DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rainwater seepage measure (also referred to as a seepage measure) provided with a deodorizing device.

[0002]

2. Description of the Related Art Generally, when a road is paved or a sewer is provided, rainwater is removed more quickly than before, and immediately flows into a river, causing various adverse effects such as flash floods. Recently, research and development of rainwater runoff control devices such as permeable pavements and rainwater infiltration basins and seepage connection pipes have been conducted with the aim of minimizing the amount of rainwater flowing into sewers and rivers. Have been.

[0003] On the other hand, as is well known, there are two types of sewage drainage systems: a split type and a combined type. The combined type removes wastewater and rainwater in the same system. Although there is no permeation function of the sewage main pipe due to the effect of the above, the above-mentioned rainwater suppression measures are in place, as well as the rainwater on the road surface, as well as the rainwater on the residential land, trying to suppress the inflow to the sewage main pipe as much as possible. I have.

In particular, there is a case where the amount of wastewater and rainwater drainage flowing into an existing sewer main (public sewer) increases due to the rapid development of residential land, etc., and exceeds the allowable drainage of the sewer main. In such a case, before rainwater merges with sewage, it can be permeated in residential land or introduced into a rainwater basin,
The infiltration at the bottom of the rainwater basin, and also the infiltration of the infiltration connection pipe and the infiltration U-shaped gutter, are intended to reduce the inflow into the sewer main pipe.

By the way, regarding the rainwater infiltration basin which is one of the rainwater runoff control devices, the present applicant has taken into account the development results of a small-diameter PVC smelt, that is, to improve the connection with the PVC pipe and the improvement of the lid for the inspection cylinder. Based on these high-quality conditions such as production efficiency and raw materials, we have developed and already provided them (for example,
See JP-A-7-286355).

[0006] Now, a general problem in a rainwater outflow control device such as a rainwater infiltration basin is the maintenance and management of the device,
Quantification of the permeation effect and influence on groundwater are mentioned. For example, clogging is mentioned in the problem of maintenance of the rainwater outflow control device.

[0007] If clogging progresses in this device, rainwater is allowed to flow out to the combined sewerage system as it is, and the effect of suppressing rainwater outflow is lost, so that the problem of clogging is the biggest problem.

[0008] To describe this in more detail, a rainwater basin in a normal sewer system is originally provided with a mud reservoir because sediment tends to accumulate therein. Since the infiltration basin is replaced with the infiltration basin, there is a conflict between mud sump and infiltration.

For this reason, a double rainwater infiltration basin has been proposed for providing a mud sump and allowing the supernatant water to penetrate (see, for example, Japanese Utility Model Application Laid-Open No. 2-26687), and a trash collecting bucket at the entrance of the rainwater infiltration basin. Proposal of providing a basket or the like (see, for example, Japanese Utility Model Application Laid-Open No. 59-192976, Japanese Utility Model Application Laid-Open No. 5-7777, etc.), and a proposal of providing a bucket for removing dust or a water-permeable bottom plate at the bottom of a rainwater infiltration basin (for example, 63-216
No. 89, JP-A-6-2357, etc.) and various proposals such as a proposal to introduce rainwater in a cyclonic manner and to flow it out from the center (for example, see Japanese Utility Model Publication No. 3-36628). I have.

[0010]

However, when a rainwater infiltration basin is used in the combined sewer system, there is a problem that odors from the sewage basin and the sewage main pipe flow back into the residential land and diffuse.

Therefore, the deodorant U trap 10 shown in FIG.
7 may be provided on the outflow side of the rainwater infiltration basin. However, in the rainwater infiltration basin 100, since the deodorant trap hinders, for example, a bucket for infiltration cannot be put in and out, the clogging which is the biggest problem described above. There was a problem that no measures were taken.

The rainwater seepage measure 100 shown in FIG. 9 will be briefly described. The box body 101 is formed of a bottomless cylindrical body made of PP, and is set on a concrete block 102. Crushed stone 103 for permeation is spread near this bottom, and rainwater permeates there.

An inflow pipe 104 is connected to the upper and lower middle portions of the box body 101, and a riser pipe 105 for outflow is erected from the bottom thereof. Are provided detachably.

An outflow side 108 of the riser pipe 105 is connected to an unillustrated sewage basin or a sewer main pipe via a deodorizing U trap 107.

Accordingly, the present invention has as its main object to prevent clogging, which is the biggest problem in rainwater infiltration basins, in a combined sewerage system, while providing a rainwater infiltration basin for a house or the like with an odor control device such as a deodorant U trap. It is another object of the present invention to provide a compact rainwater infiltration basin while having a deodorizing device and a clogging preventing device.

[0016]

In order to achieve the above object, the gist of the present invention is as follows: 1) an opening for an inspection tube or a lid frame upward, a rainwater inlet horizontally, and a downward seepage. In the synthetic resin rainwater infiltration basin provided with the cylindrical body, the outflow side of the deodorant U trap having an inflow opening opened flush with the opening of the infiltration cylindrical body, the sewage basin of the combined sewer system or A single plate that communicates with the sewage main pipe and closes both the inlet of the U trap and the opening of the infiltration cylinder is provided, and the inlet of the U trap is provided as a mounting portion for the plate. Is made to enter and exit through the opening for the check tube or the lid frame, thereby making the whole compact and easy to maintain and improve the permeation effect of rainwater. Etc. In the rainwater infiltration basin equipped with a deodorizing device, 2) an opening for an inspection tube or a lid frame is provided upward, a rainwater inlet is provided horizontally, and a penetration cylinder is provided downward. In the synthetic resin rainwater infiltration basin, the solid material is prevented from directly flowing into the cylindrical body for infiltration, and only the solid material is captured. A deep-bottom type infiltration bucket provided with a water hole is accommodated, and the outflow side of the deodorization elbow, whose inflow side is open as a sealing portion with rainwater accumulated in the infiltration bucket, is used as a wastewater basin of a combined sewer system or By communicating with the sewage main pipe and providing a perforated plate on the inflow side of the elbow, the burden on the sewage treatment plant is reduced and priority is given to rainwater permeation. Going in and out of Accordingly, in rainwater percolating box provided with a deodorizing apparatus characterized by to facilitate maintenance and to improve the penetration effect of rainwater.

First, a rainwater infiltration basin 1 equipped with the deodorizing device of the present invention will be outlined (used without suffixes such as A and B in the drawing). This is a box body 2 and a permeation bucket (solid-state capture device), all made of PVC injection molding (made of synthetic resin).
10, composed of a U-trap 4 or elbow 5 and a perforated plate 6 for deodorization, in which rainwater in the house or the like is introduced into the basin body 2, where it penetrates, and the remaining rainwater is introduced into a sewage basin or sewage main pipe (not shown). Although it flows out, the odor that flows back from the sewage basin or sewage main line at that time is blocked by the U trap 4 or the elbow 5 so that the odor does not diffuse from the basin body 2 to the house or the like.
By easily taking out and cleaning the permeation bucket 10 housed in the basin body 2 and the attached eye plates 6 and 50, each clogging is prevented and permeation is promoted.

That is, the sediment and dust collected from these are removed, and the infiltration bucket 10 and the perforated plates 6, 50 are put in and out together with the elbow 5, or the perforated bucket 6 is used independently of the U trap 4. This facilitates the maintenance and management of the rainwater infiltration basin 1 and enhances the infiltration effect.

One or more rainwater inflow pipes (rainwater inflow ports) 7 are connected to the basin body 2, and a sewage basin or a sewage main pipe is connected to the outlet side of the U trap 4 or the elbow 5. One outlet pipe 8 to be connected is connected, and these pipes 7 and 8 are ordinary PVC pipes for residential land (75 to 100 mm).

Next, a first embodiment will be described. In FIG. 1, a rainwater infiltration basin 1A provided with the deodorizing device of this embodiment is a permeation bucket (penetration cylinder) provided through a basin body 2A and a connection tube 9 connected to a lower portion of the basin body 2A. Body) 10, a U-trap 4A opened in the box body 2A and supported by the connecting tube 9, and an inlet 11 of the U-trap 4A and an upper end opening of the connecting tube 9 are both closed. In addition, it is roughly constituted by one curved plate (a device for capturing only solid matter) 6A which can be put in and out of the inspection tube 12. Therefore, the inflow port 11 of the U trap 4A is used as a perforated plate mounting portion.

At the side of the main body 2A, one or a plurality of inlets (rainwater inlets) 13, 13 are provided, and a rainwater inlet pipe 7A for in-home use is bonded to these inlets 13. Joined.

An in-house rainwater outflow pipe 8A is adhesively bonded to the outlet side of the U trap 4A via an elbow 14.

Further, the inspection cylinder 12 is adhesively bonded to an upwardly facing inspection cylinder receptacle (opening) 15 on the box body 2A, and a lid 17 is provided on the upper end of the inspection cylinder 12 via a lid frame 16. It is covered to open and close freely. Of course, the lid frame 16 may be provided directly on the box body 2A.

Therefore, each of the inlet pipes 7 is
When rainwater flows in from A, it flows down and accumulates in the infiltration bucket 10 through the curved perforated plate 6A, and the U trap 4
A, the rainwater which has flowed into the infiltration bucket 10 penetrates into the house where the crushed stone 19 is spread through the many vertical slit water holes 18, 18, and also flows out from the U trap 4A. It also flows out to the pipe 8A.

[0027] Then, since dust such as earth and sand and fallen leaves in the rainwater is captured by the one eye plate 6A, the rod 20 for taking in and out is appropriately (for example, periodically) taken out from the inspection cylinder 12 and taken out. Remove solid matter such as garbage. Therefore, cleaning of the eye plate 6A can be performed easily. Then, the odor flowing backward from the outflow pipe 8A is blocked by the U trap 4A and does not diffuse into the house.

The configuration of the first embodiment will be described in more detail. Three inlet ports 13 are provided on the side of the basin body 2A, an inspection pipe port 15 is provided above, and a connecting pipe port 21 having the same diameter as the receiving port 15 is provided below. Further, an inward flange 22 is formed at the bottom of the pipe inside the inflow port 13 and serves as an inner fitting portion on the outer periphery of the perforated plate 6A.

The access rod 20 described above is implanted on the upper surface of the perforated plate 6A, and the U-trap connecting foot 23 is provided on the lower surface.

The U-trap connecting foot 23 is removably inserted into the inlet 24 of the U-trap 4A.

The U trap 4A constitutes a U trap by using two elbows and joining the horizontal portions 26, 26 of both elbows and combining them.

That is, the horizontal portions 26 of these elbows
Is inserted into and supported by a U-trap support receiving portion 27 formed in the connecting cylinder 9, but the horizontal portion 26 of the inlet-side elbow of the U-trap 4A forms a spigot, and is supported by the U-trap supporting receiving portion. The horizontal portion 26 of the outlet side elbow of the U trap 4A forms a spigot, and is inserted into the stopper portion of the U trap support receiving portion 27, and these horizontal portions 2
6 are joined to each other.

An upper portion of the connection tube 9 forms a receiving port, and
A and is spliced with the spigot 21 of A.
Is formed and is adhesively bonded to the opening receptacle of the permeation bucket 10.

On the side surface of the penetration bucket 10, for example, a slit width of 5 mm, a pitch of 15 mm, and a slit length of 60 mm
The vertical slit water hole 18 is formed in two stages, upper and lower, and an appropriate water hole 30 is also provided on the bottom surface.

As a modification of the rainwater infiltration box 1A provided with the deodorizing device of the first embodiment, the connecting cylinder 9 is directly used on the concrete block (102) shown in FIG. 9 without using the infiltration bucket 10. It may be installed in.

Therefore, the rainwater infiltration basin 1A provided with the deodorizing device shown in FIG. 1 can be buried deeply avoiding the surface loam layer (depth of about 80 cm), can be installed on the downstream side of the house, It is convenient to install in a residential area with ample space where the U trap 4A may slightly protrude downstream.

Next, a rainwater infiltration basin 1B provided with the deodorizing device of the second embodiment will be described. In FIG. 2, FIG. 3, FIG. 4, and FIG.
In this method, an elbow 5B is used in place of the U trap 4A, and a perforated plate 50 is mounted on the inflow side of the lower opening 33 of the elbow 5B. It is as compact as possible to get in and out with 10B.

Particularly, on the inflow side of the lower opening 33, a cylindrical dish 50 having a lattice-shaped bottom surface and a side surface having a vertical slit water hole is detachably mounted from below. Therefore, the inflow side of the lower opening 33 serves as a perforated plate mounting portion.

Further, this infiltration bucket 10B is
Cylindrical body with bottom (perforated cylindrical body) 3 integrally formed with B
1 is housed so as to be able to enter and exit freely.

Therefore, the second embodiment is
Also referred to as an elbow-type trapped rainwater infiltration box 1B composed of a box body 2B having a bottomed cylindrical body 31 with a hole, and a small-diameter (for example, 250 mmφ) inspection tube 12 or lid frame 16 (both in FIG. Is suitable for a rainwater infiltration basin made of PVC, which can be attached, and has a deodorant function (trap function).
With the addition of (1), rainwater flows, which is particularly convenient to install in a home drainage system in a narrow land.

First, the rainwater infiltration trough 1B with an elbow trap will be outlined. The mouth of the inspection cylinder (a lid frame for fitting a manhole cover may be directly joined, or an inlet or a rubber ring receptacle) 15B may be directed upward to the box body 2B. Entrance port (may be a port or rubber ring port) 13
B, the outlet port 32 (which may be an outlet or a rubber ring port) 32 on the other side, and the above-mentioned bottomed cylindrical body 31 which is deeper downward and slightly squeezed slightly downward are integrally formed with each other. Is formed.

The inlet 13B for the inlet is the outlet 3 for the outlet.
2 and on the same tube axis in a plan view, and is opened upward with a slight difference in water level (for example, 20 mm) from the receiving port 32. The bottomed cylindrical body 31 has substantially the same shape. A bottomed cylindrical infiltration bucket 10B having a vertical slit water hole 18B at the upper end, which has been made as large as possible, is mounted so as to be able to be taken out.

Therefore, this infiltration bucket 10B includes:
As much rainwater as the lower opening 33 of the elbow 5B is sufficiently immersed is collected, and a water sealing effect is exhibited. In addition, the bottomed cylindrical body 31
May be configured as a detachable body (see, for example, JP-A-7-292758).

An elbow 5B is connected to the outflow port 32 of the rainwater immersion tub 1B with a trap to form a trap. The lower opening 33 of this elbow 5B is
It is immersed in rainwater within 0B. Therefore, it is convenient to reduce the diameter of the rainwater infiltration basin with the elbow trap.

When the above-described rainwater infiltration basin 1B with an elbow trap is used, for example, in a house drainage system, rainwater mixed with solids flows in from an inlet and flows out from an outlet. The contaminants such as earth and sand, fallen leaves, etc.) settle and accumulate in the infiltration bucket 10B, and the rainwater excluding the solids penetrates and flows out to the sewage main pipe.

At this time, the odor flows back to the outlet from the sewage basin or sewage main pipe at the outflow destination.
Since it is shut off by the water sealing of B, it does not leak to the inside of the cell body 2B as well as to the inflow port.

The solid matter deposited in the infiltration bucket 10B is taken out and cleaned integrally with the elbow 5B as described later. Of course, the eye plate 50 of the elbow 5B may be removed and cleaned. Therefore, clogging due to permeation is eliminated.

In this case, the rainwater infiltration basin 1B with the elbow trap is designed to reduce the diameter while increasing the pool of rainwater as much as possible. Further, the basin body 2B, the permeation bucket 10B, the elbow 5B, etc. In order to facilitate cleaning, a structure is adopted in which the infiltration bucket 10B and the elbow 5B are detachably integrated, or are separated and integrated with an adhesive or the like so that they can be taken out at the same time.

The details of this structure will be described below in
B "," penetrating bucket 10B ", and" elbow 5B ".

First, the "cell body 2B" will be described. Mainly in FIGS. 2 and 4, the box body 2B is a PVC injection-molded product, and the dimensions of the inspection port 15B are formed as follows.

That is, the connected home drain pipe is 75 mm
When the opening diameter of the penetration bucket 10B is about 150 mmφ in the case of φ to 200 mmφ, for example, 100 mmφ, the diameter of the inspection tube receiving port 15B is about 200 mmφ because the elbow 5B is integrated with the penetration bucket 10B. Is formed. Therefore, the diameter of the inspection tube receiving port 15B is made larger than the opening diameter of the infiltration bucket 10B so that it is easy to enter and exit even when the diameter is reduced by the lid frame (not shown).

The overall shape of the bottomed cylindrical body 31 of the box body 2B is formed substantially in conformity (substantially the same shape) with the shape of the deep penetration bucket 10B, and a large number of water passage holes 46 are provided. ing. A pair of upper and lower sliding L-shaped grooves 34, 34 is formed from the vicinity of the outlet port 32 to the upper end of the bottomed cylindrical body 31 with the outlet port 32 interposed therebetween.

Next, the “penetrating bucket 10B” will be described. Primarily in FIG. 2 and FIG. 3, this is an ABS injection molded product, and employs a deep bottom type in order to increase the amount of rainwater storage as much as possible. For example, the opening diameter is approximately 1
If it is 50 mm and the bottom diameter is about 140 mm, the depth is about 2
40 mm.

A large number of vertical slit water holes 18B are formed in a single step at the upper end of the side surface of the permeation bucket 10B to allow rainwater to overflow and permeate.

The body 35 of the infiltration bucket 10B has a flat surface on the side surface perpendicular to the tube axis of the outlet and inlet ports 13B and 32, and is slightly larger than the bottomed cylindrical body 31 of the box body 2B. A space is formed to secure the water storage amount, and the numbered handle 36, which is always erected, does not interfere with the entry and exit of the box body 2B.

The handle 36 of the infiltration bucket 10B is provided integrally on the upper part of the elbow bracket 38, and the opening of the body 35 of the infiltration bucket 10B is made substantially the same shape as the opening of the bottomed cylindrical body 31. Is also good.

A flange 37 extends from the open end of the infiltration bucket 10B and is fitted on the inner surface of the bottomed cylindrical body 31. Therefore, it is possible for solid matter to directly flow into the bottomed cylindrical body 31. Absent.

The flange 37 formed with one radius extends on the outer periphery of the opening of the infiltration bucket 10B, and an elbow bracket 38 described later stands upright on the outflow port 32 side of the flange 37. And the vicinity thereof are notched.

The elbow bracket 3 having a curved plate shape is provided on the outlet 32 side of the opening of the infiltration bucket 10B.
Reference numeral 8 stands integrally (integrally molded). An outer surface of the elbow bracket 38 is provided with a ridge 39 having substantially the same height as the flange width of the flange 37 to prevent solids from flowing into the bottomed cylindrical body 31.

An elbow insertion hole 40 is opened at a position of the elbow bracket 38 facing the outlet port 32, and an outer periphery of the elbow insertion hole 40 and an outer surface thereof are provided.
A ring-shaped ridge 41 is provided.

The height of the ring-shaped protruding portion 41 is set lower than the height of the edge protruding portion 39 so that even if the back surface of the elbow flange 42 of the elbow 5B abuts, the ring-shaped protruding portion 41 projects to the cell body 2B and does not interfere with the inner surface thereof. I have to. On the concentric outer periphery of the ring-shaped protruding portion 41, a packing fitting protruding portion 43 having the same height as the edge protruding portion 39 and partially overlapping is provided.

The edge protruding portions 39 at the left and right ends and the lower end of the elbow bracket 38 are provided with
Insert pieces 45, 45 to be inserted into the upper and lower slide L-shaped grooves 34 provided in B are formed.

Next, the "elbow 5B" will be described. This is polyethylene or a similar resin, for example, a PVC injection-molded product. The lower opening 33 is formed of a normal tube, and the upper opening 47 is formed of an eccentric enlarged portion having the same tube bottom. are doing. An elbow flange 42 is formed at the open end of the eccentric enlarged diameter portion, and the elbow flange 42 prevents the elbow 5B from being removed when the elbow 5B is mounted on the elbow bracket 38.

That is, the back surface of the elbow flange 42 comes into contact with the ring-shaped protrusion 41 of the elbow bracket 38 as described above, and the elbow flange 42 and the locking portion 5
The ring-shaped ridge 41 is sandwiched between the ring-shaped protrusions 3.

Therefore, the elbow 5B is inserted into the elbow insertion hole 4 of the elbow bracket 38 in the vertical state.
In order to insert it into the tube 5, the tube is first inserted with the lower opening 33 of the elbow 5B horizontal while the tube axis is gradually vertical.

Next, the elbow 5B is passed over the elbow insertion hole 40 while the pipe axis of the upper opening 47 of the elbow 5B is slightly inclined.

Next, if the pipe axis of the upper opening 47 is made horizontal, the ring-shaped protruding portion 41 can be sandwiched between the locking portion 53 and the elbow flange 42, and the elbow 5B is prevented from falling off. become.

At the lower opening 33 of the elbow 5B, a bottomed cylindrical perforated plate 50 provided with a number of vertical slit water holes 51 on the side and bottom is detachably mounted or fixed. Therefore, the solid matter of the infiltration bucket 10B is prevented from flowing out to the outflow port 32, and the load on the sewage treatment plant is reduced.

Further, since the vertical slit water hole 18B of the permeation bucket 10B is located at a position lower than the outlet port 32,
Rainwater first enters the infiltration bucket 10B, becomes full,
The water overflows from the vertical slit water hole 18B, flows out from the water hole 46 of the box body 2B, and penetrates into the crushed stone 19 (see FIG. 1).

Further, when the amount of rainwater increases, a part of the rainwater flows through the elbow 5B to the wastewater basin or the sewage main pipe. Therefore, the structure is such that rainwater is always given priority to permeation, and since rainwater is collected up to the lower end of the vertical slit water hole 18B of the permeation bucket 10B, a water-sealing portion is formed by the elbow 5B, and the odor flows backward. Cut off.

Next, a rainwater infiltration basin 1C provided with the deodorizing device of the third embodiment will be described. In FIGS. 6, 7 and 8, this is an existing deep-bottom type rainwater infiltration basin with an additional deodorant elbow 5C, and the difference from the second embodiment is as follows. Therefore, the functions of rainwater permeation, removal of clogging by solid matter, and deodorization basically do not change. In the drawings, the suffix C is attached only to the elements specifically described, and the description of the common parts is omitted.

That is, in the box body 2C, there are two inlet ports 13C, and the bottomed cylindrical body 31C is made separate from the box body 2C, and the connecting tube 55 for permeation is interposed. It is formed into a deep bottom type to increase the amount of permeation. In addition, these connections are performed by adhesive bonding of a socket and a spigot.

The pair of upper and lower slide L-shaped grooves 3
4 is stopped from being formed on the box body 2C, and is integrally formed on the elbow 5C as a pillar. Up and down slide L of these pillars
An upward semi-circular plate 61 is formed integrally between the grooves 34C, 34C.

A part of the upper opening 47C of the elbow 5C is cut off to constitute a separate guide short pipe 56, and the outer end of the guide short pipe 56 is connected to the outlet port 32 of the box body 2C.
Inserted and joined to C.

The elbow flange 42 at the opening end of the upper opening 47C of the elbow 5C and the guide short pipe 56
And the short pipe flange 62 at the inner end of the guide pipe via a seal packing (not shown).
In addition to preventing rainwater from leaking, it also prevents odor from leaking.

Therefore, the guide short tube 56 is connected to
After insertion and joining to the outlet 32C for the outlet of C,
The penetrating bucket 10C is accommodated and placed in the bottomed cylindrical body 31C having a slit, the flange 37 is fitted on the inner surface of the box body 2C, and the pair of vertical sliding L-shaped grooves 34C, 34C, 34C is brought into contact with the back surface of the short pipe flange 62 of the short guide pipe 56, thereby restricting vertical and horizontal rotation and positioning.

Next, in the elbow 5C, the upper opening 4
7C is formed of a normal pipe having the same diameter as the guide short pipe 56, and the lower opening 33, that is, the vertical part is formed in a substantially rectangular shape having an arc along the inner surface of the infiltration bucket 10C (FIG. 8). ), As close as possible to the inner surface of the infiltration bucket 10C. The inflow side is a mounting portion for a perforated plate.

Next, the handle 36C receives an eccentric load due to the sliding friction of the upper and lower slide L-shaped grooves 34C and 34C when the handle 36C is moved in and out integrally with the elbow 5C. , Which are shifted to the elbow 5C side.

That is, the handle 36C is made of resin molding, and grips the inverted U-shaped grip portion 57, the curved plate body 58 extending over the upper half of the upper opening 47C, and the upper inner periphery of the infiltration bucket 10C. And an arm 59 with a pair of claws 60 to be held.

Therefore, the elbow 5 is added to the infiltration bucket 10C.
After the C is inserted, the curved plate body 58 of the handle 36C is brought into contact with the back surface of the elbow flange 42 and the upper opening 47
C, sandwiched between the upward semi-circular plates 61, and penetrated into the bucket 1 by the claws 60 of the pair of arms 59.
When the upper inner periphery of OC is gripped, the penetration bucket 10C, the elbow 5C and the handle 36C can be set integrally with the chuck.

As a result, when the handle 36C is lifted from the inspection tube, both the infiltration bucket 10C and the elbow 5C can be taken out.

It is needless to say that the rainwater seepage measure provided with the deodorizing device of the present invention can be applied not only to a house but also to a public place such as a park or an apartment complex.

[0083]

According to the first aspect of the present invention, since the deodorizing device is provided in the rainwater infiltration basin, even when used in a combined sewer system, the odor that flows backward can be prevented. Since the common eye plate for the body can be easily taken in and out once, it is easy to clean them, and furthermore, the clogging of the rainwater infiltration basin can be prevented and the seepage effect can be promoted. Priority is given to infiltration, and the remaining infiltration rainwater is drained to the combined sewer system, reducing the processing load.
It can contribute to the control of rainwater runoff.

In addition, even if the perforated plate can be put in and out of the inspection tube or the like at a time, the whole can be made compact and can be installed even on a small land.

According to the second aspect of the present invention, in addition to the above, solid matter is deposited in the permeation bucket serving as a water sealing portion of the deodorization elbow, and the permeation bucket is integrated with the deodorization elbow and taken out for cleaning. The burden on the user can be particularly reduced.
