Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage concrete pipe to be buried near a road or the like and a method for producing the same.

[0002]

2. Description of the Related Art Generally, a drainage concrete pipe having a water passage portion is buried near a road in order to improve drainage of the road. As the water passage of this drainage concrete pipe, water passages are generally formed, but as a means to further improve the drainage efficiency, part or all of the wall such as the upper wall and the side wall is made of natural stone particles. There is a water-permeable panel formed by binding a material such as water with a binder.

[0003]

However, the concrete pipe for drainage using the water permeable panel as described above has the following problems. That is, when manufacturing a drainage concrete pipe using a water permeable panel, the water permeable panel is installed at a predetermined position of the form, and the cement paste is poured to form the other part with concrete, but at this time. The cement paste permeated into the water-permeable space of the water-permeable panel, impairing the water-permeable performance of many parts of the water-permeable panel.

[0004]

Means for Solving the Problems The means of the present invention taken to solve the above problems are as follows. The first means is a concrete pipe for drainage, in which a container made of a material that does not allow cement paste to penetrate substantially pierces the wall portion and is buried in a required number. There is a concrete pipe for drainage, in which the inside of the container is filled with a water-permeable member obtained by binding a granular material in a water-permeable manner.

The second means is a concrete for drainage according to the first means, wherein one or both of the inner surface and the outer surface of the wall portion of the container is provided with a retaining member for preventing the container from coming off. It is a tube.

[0006] A third means is a method for producing a concrete pipe for drainage, which is made of a material that does not allow cement paste to penetrate into a required portion of a mold for molding the concrete pipe for drainage, and A step of mounting a required number of containers filled with a water-permeable member formed by binding the granular material to allow water permeation, and a step of pouring cement paste to the outside of the container and molding a drainage concrete pipe, It is a method of manufacturing a concrete pipe for drainage including.

The material forming the container is, for example, vinyl chloride resin (PVC), but is not limited thereto. The water-permeable material is solid, such as natural stone grains or fly ash (made by processing volcanic ash into small particles) with a binder made of synthetic resin to form a large number of water-permeable voids inside. For example, it is in a shape. In this case, the compounding ratio is, for example, 1 by weight but 15 by weight for the aggregate (natural stone particles or fly ash), but is not limited thereto. Moreover, the particle size of the natural stone particles is, for example, 4 to 5 m.
The particle size of fly ash is about 1 to 2 mm, but is not limited.

The wall portion in which the container is embedded is an upper wall, a side wall,
The bottom wall may have one surface or a plurality of surfaces, and is appropriately selected according to the application of the concrete pipe for drainage. For example, when burying the entire concrete pipe in the ground, use the one with the housing embedded in each of the top wall, side wall, and bottom wall to efficiently remove the water that oozes into the ground. Allow it to be taken into the tube.

Further, when the upper wall is exposed and buried in the ground, it is common to use the one in which the housing is buried only in the upper wall, but the other housing is buried in the housing. There is no problem. The number of containers to be buried is not limited,
It is also possible to arbitrarily set the water permeability by adjusting the number of buried containers.

[0010]

The water-permeable concrete pipe for drainage according to the present invention is buried near a road or the like so that its upper surface is flush with the ground. As a result, rainwater or the like permeates through the water-permeable member portion filled in each container, enters the pipe, and is drained. Although the water-permeable member allows water to pass therethrough, leaves, wood chips, dust, and the like do not pass through and are separated, so that they can be prevented from clogging inside the drainage concrete pipe.

The water-permeable member is filled in the container and has a water-permeable function, but unlike the water-permeable hole, the hole is not opened. As a result, it is possible to prevent the inconvenience that, for example, the heel of a pedestrian's shoes, particularly the heel of a woman's high heel, is stuck and stumbles.

In the case where the container according to the second means is provided with the latching member, the one provided on the inner wall can prevent the filled water-permeable member from coming out. In addition, with the one provided on the outer wall, the container itself can be prevented from coming out.

In the production of the water-permeable concrete pipe for drainage according to the third means, the water-permeable member is surrounded by a container formed of a material that does not allow cement paste to penetrate, and the cement paste is external to the container. Since it is poured into the side, the cement paste can be prevented from seeping into the water permeable member, and a drainage concrete pipe having water permeability can be manufactured.

The present invention will be described in more detail based on the embodiments shown in the drawings. 1 is a perspective view of a concrete pipe for drainage according to the present invention, FIG. 2 is a sectional view of a concrete pipe for drainage according to the present invention, and FIG. 3 is a perspective view showing a structure of a container. Reference numeral C is a concrete pipe for drainage, which is formed in a substantially rectangular tube shape. The concrete pipe C for drainage has a required length,
It has a top wall 1, side walls 2 and 3, and a bottom wall 4, and has a water passage 7 inside.

Five accommodating bodies 5 are embedded in the central portion of the upper wall 1 in the width direction so as to penetrate through the upper wall 1 in parallel with the axial direction at equal intervals. As shown in FIG. 3, the container 5 has a flat cylindrical shape that penetrates vertically, and the lower side is formed to be slightly concave. On the inner surface 50 of the wall portion of the container 5, hooking members 51 are provided at four locations in the circumferential direction so as to project inward. A locking member 52 is provided on the outer surface 50a at a position corresponding to the locking member 51 so as to project outward.
The container 5 is made of vinyl chloride resin, which is a material through which the cement paste does not penetrate.

The container 5 is filled with a water permeable member 6. The water permeable member 6 is made by binding natural stone particles such as brocade stone with a binder made of synthetic resin, and has a large number of irregular water-flowing voids (not shown) extending from the upper surface to the lower surface. Water such as rainwater is smoothly transmitted. In the present embodiment, the water permeable member 6 is filled in the entire inside of the container 5, but it may be partially filled, for example, in the upper 2/3.

At both ends of the upper wall 1 in the longitudinal direction, notch slots 10 are provided for hanging a hanging tool when suspending the concrete pipe C for drainage. In addition, fitting recesses 20 and 30 are provided at both ends of the side walls 2 and 3 in the longitudinal direction for fitting the connecting metal fittings when the drainage concrete pipe C is connected. Further, a U-shaped cushion material 12 is embedded in one end surface 11 in the longitudinal direction of the drainage concrete pipe C.

(Operation) The operation of this embodiment will be described with reference to FIGS. The drainage concrete pipe C is buried near a road so that the surface of the upper wall 1 is flush with the ground, for example. Rainwater or the like permeates through the water-permeable member 6 portion filled in each container 5, enters the water passage 7, and is drained.
Although the water-permeable member 6 allows water to pass therethrough, it does not allow leaves, wood chips, dust, and the like to pass through and is separated. Therefore, it is possible to prevent water from flowing due to clogging of these inside the water passage 7 of the concrete pipe for drainage.

The water-permeable member 6 is filled in the container 5 and has a water-permeable function, but unlike the water-permeable hole, the hole is not opened. As a result, it is possible to prevent the inconvenience that, for example, the heel portion of a woman's high heel fits and is stuck. Also,
Since the container 5 is provided with the hooking members 51 and 52, it is possible to prevent the water permeable member 6 from coming out and prevent the container 5 itself from coming out.

The concrete pipe C for drainage according to the present invention is manufactured as follows. First, drainage concrete pipe C
At a required position of the molding frame (not shown), a container 5 formed of a material such as vinyl chloride resin that does not allow the cement paste to permeate and having a water-permeable member 6 filled therein is mounted. Next, the cement paste is poured into the outside of the container 5,
It is cured for a certain period of time to be solidified, taken out from the molding frame, and a drainage concrete pipe C is molded.

According to this manufacturing method, since the water-permeable member 6 is surrounded by the container 5 into which the cement paste does not permeate, the cement paste is poured into the outside of the container 5 and does not enter the inside. Therefore, the cement paste does not soak into the water permeable member 6 and the water permeability is not impaired, and the drainage concrete pipe C having the water permeability in the water permeable member 6 portion can be manufactured. The present invention is not limited to the illustrated embodiments, and various modifications can be made within the scope of the claims.
