Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drainage pipe that is inserted into a hole drilled into the soil from an inclined surface in order to drain water contained in the soil inside the inclined surface.

If a large amount of water is present in the soil 1 constituting a slope such as a cliff as shown in FIG. 1, landslides are likely to occur, which is dangerous.

For this reason, in places where there is a risk of landslides, a horizontal hole 2 is drilled from this slope to ±1 inside, gradually increasing in height as it goes deeper, and inside this horizontal hole 2. A perforated metal tube was inserted into the tube to drain excess moisture within ±1. However, if the water handling pipe inserted into the horizontal hole 2 is a simple metal porous pipe, the small through holes drilled in the circumferential surface of the perforated pipe are likely to become clogged, and the inside of the soil 1 may become clogged. Water could not be drained sufficiently.

The drain pipe of the present invention eliminates the drawbacks of conventional products as described above.

The present invention will be described below with reference to drawings showing examples.

The connecting fittings 6 to be installed at the joints when a long drainage pipe is formed by connecting a plurality of pipe bodies 3 formed in the same manner as in FIG. Made in Japan.

The end face shape of the pipe main body 3 made by integral extrusion molding of synthetic resin is formed symmetrically with respect to the center line in the vertical direction, and the shape of the circumferential face is approximately circular. The upper ends of the dog-shaped central wall portions 7.7 provided near the center are connected by an arc-shaped connecting portion 8, and each central wall portion 7.7
Arc-shaped outer circumferential wall portions 9.9 are integrally formed at the lower ends of each.

Projections 10.10 are formed outwardly at the upper ends of the outer peripheral wall portions 9.9, and vertical wall portions 11.11 are formed upwardly at the inner edges. ,
A slit-like gap 12 is formed between the vertical wall portions 11.11.

Further, on the upper surface of the lower half portions 7a, 7a of the central wall portion 7.7,
A plurality of partition walls 13.1 parallel to each other diagonally upward
3 is formed. A hook-shaped portion 13as13a bent outward is integrally formed at the upper end of each partition wall portion 13.13. The edge of this hooked portion 13as13a and the upper edge of the adjacent partition wall portion 13.13 or the protruding portion 10°10
There are slit-shaped gaps 14 and 14 between the upper surface and the upper surface, respectively.
is formed. In addition, the innermost partition wall portion 13
．． A similar gap 14.14 is also formed between the upper edge of the connecting portion 13 and the lower surface of the eave-like portions 8a, 8a projecting on both sides of the connecting portion 8.

Next, as shown in FIG. 3, the upper spacer 4 is inserted into a gap formed in the upper half of the pipe body on the inner peripheral surface of the arc-shaped base 15 that can be brought into close contact with the upper half of the pipe body 3. 14. Eaves-like portions 16.16 are formed inwardly at intervals corresponding to the intervals of ]4. In addition, the lower spacer 5 is connected to the pipe body 3
An upright wall part 18 that can be inserted into a gap 12 formed in the center part of the lower surface of the pipe body 3 is formed on the upper surface of the central part of the arc-shaped base part 17 that can be brought into close contact with the lower half part. Both the upper and lower spacers 4.15 having such an end face shape are connected to the pipe body 3.
The length is much shorter, for example, about 2 to 3 cm.

Furthermore, the connecting tool 6 for connecting adjacent pipe bodies 3.3 is formed in a substantially X-shape as shown in FIG. It can be inserted freely without rattling.

The length of the connecting tool 6 is set so that the adjacent pipe bodies 3.3 can be connected with sufficient strength for each spacer 4.3.
It is set to be longer than 5, for example, about 1Qcm.

Each part 3.4.5.6 formed as described above is
The drain pipe 19 is assembled as shown in the figure. That is, the upper spacer 4 brings the lower surface of the base portion 15 into contact with the upper surface of the pipe main body 3, and each eave-shaped portion 16.
16 inserted into the gap 14.14, the pipe body 3
It is fixed with adhesive etc. Such an upper spacer 4 is engaged with the pipe body 3 at the end face of the pipe body 3, and is slid on the surface of the pipe body 3 to a predetermined attachment position.

A lower spacer 5 is attached to the lower half of the pipe body 3 to which the upper spacer 4 is fixed in this manner. The lower spacer 5 is fixed to the pipe body 3 with an adhesive or the like with the upper surface of the base 17 in contact with the lower surface of the pipe body 3 and the vertical wall portion 18 inserted into the gap 12. Both the upper and lower spacers 4 are attached to the pipe body 3 in this way.
5 is for preventing gaps 12 and 14 of the pipe body 3 from being crushed by earth pressure when the water draining vibrator 19 is buried in the soil. fixed every 10 to 29 cm). Furthermore,
When connecting a plurality of water draining vibrators 19 assembled in this way to form a long water draining pipe to be inserted into the horizontal hole 2 shown in FIG. 1, the connection shown in FIG. Part 6
The pipes 19 and 9 for draining water are fitted inside the center wall part 7.7 so as to pass over them, and the end surfaces of the pipe bodies 3.3 of both pipes are brought into contact with each other. The pipe 19.19 and the connector 6 are fixed with adhesive or the like.

Further, upper and lower surface spacers 4.5 are also attached to this connection portion.

The drainage pipe 19.19 constructed in this way and connected by the connector 6 is buried in the soil by being inserted into the horizontal hole 2 as shown in FIG. In order to facilitate the work and to prevent earth and sand from entering the inside of the pipe body 3, a cap body 20 is attached to the end of the innermost drain pipe 19 as shown in FIG.

This cap body 20 has a conical part 22 formed integrally with a short cylindrical part 21 into which the end of the pipe main body 3 can be fitted.
A notch 23 for a bidet is formed in both sides of the button 1, and a small through hole 24 is formed in the conical part 22 to allow communication between the inside and outside of the circular button part 22. Furthermore, when the water drain pipe 19 is inserted into the horizontal hole 2, the protrusions L01lO on both sides of the pipe body 3 dig into the inner surface of the horizontal hole 2, so that the water drain pipe 19 is inserted into the horizontal hole. 2, and the draining m-vibrator 19 will not be turned upside down.

Further, depending on the case, a net may be wrapped around the water draining pipe 19 when it is inserted into the horizontal hole 2.

The drainage pipe 19 of the present invention configured as described above and buried in the soil introduces moisture contained in the surrounding soil into the main body 3 through the gap 12.14 of the pipe main body 3, It is discharged to the outside through a water passage formed inside the pipe body 3.

Does the water draining pipe of the present invention extend along the length of the vibrator? Since slit-like gaps of J number are formed, the ability to collect water contained in the surrounding soil is large, making it possible to completely prevent landslides.
