[Technical field to which the invention belongs]

 The present invention is applicable to drainage pavement such as reinforced concrete L-type, pedestrian road boundary block, precast culvert, apron, V-shaped ditch, dish-shaped ditch which can collect and drain rainwater without clogging. The present invention relates to concrete products for collecting and draining water.

[0002]

[Prior art]

 The drainage pavement has a structure in which asphalt mixture for drainage pavement (open ascon) is used for the surface layer or the surface layer / base layer for the purpose of draining rainwater quickly from the road surface, and water does not penetrate below the roadbed. By the way, the permeable pavement allows the water on the road surface to penetrate below the subbase for pedestrian roads, and the drainage pavement allows the water on the subsurface to lower the strength below the subbase for the roads. The structure does not penetrate below. This drainage pavement improves visibility by preventing splashing and splashing in rainy weather, preventing hydroplaning, and preventing headlights from reflecting off the road at night or in rainy weather, as well as reducing vehicle noise. There are additional effects such as. In order to exhibit these effects, it is required that the drainage pavement be constructed so that rainwater and the like do not accumulate on the surface or inside. It is also said that if rainwater remains inside the drainage pavement for a long time, the asphalt binder and the aggregate will peel off, which will cause the durability of the drainage pavement to decrease. Therefore, it is necessary to consider drainage (edge treatment) at a position below the pavement surface (the lower surface of the open ascon). Specifically, a water-impermeable seal layer (usually sprayed with asphalt emulsion containing rubber) is provided on the back of the drainage pavement, and by providing a cross slope, the rainwater is guided toward the road shoulder, For example, a method of burying a water conveyance pipe such as a perforated PVC pipe, collecting rainwater into this water conveyance pipe, and draining the water is adopted.

[0003]

[Problems to be solved by the invention]

 However, as described above, the structure in which the drainage channel is formed in the ground at the shoulder of the road with the water conveyance pipe requires a configuration for surely guiding rainwater to the water conveyance pipe. In other words, the method of collecting and draining water by arranging such water conveyance pipes involves various methods such as soil excavation and level adjustment, filling of crushed stone around the water conveyance pipe, and formation of water conveyance channels with a waterproof sheet at the time of construction at the site. This process had to be performed, and there were many types of construction members, so the workability was extremely poor. On the other hand, there are known reinforced concrete L-shape, pedestrian road boundary block, precast culvert, apron, V-shaped ditch, dish-shaped ditch, etc., which constitute shoulders. These concrete products collect rainwater flowing from the surface of the road. However, it was not compatible with the introduction of drainage pavement.

[0004]

[Means for Solving the Problems]

 The present invention has been proposed in view of the above, and has a water collecting section composed of a permeable concrete in which a water guide pipe that is continuous in a longitudinal direction is buried at a corner of a concrete product for collecting and draining the side of which contacts the drainage pavement. The present invention relates to a concrete product for collecting and draining water, which is provided integrally.

[0005]

[Action]

 The concrete product for drainage collection and drainage according to the present invention is a water-conducting pipe at the corner on the underside roadway side of concrete products such as reinforced concrete L-type, pedestrian road boundary block, precast culvert, apron, V-shaped groove, and dish-shaped groove. The water collection part made of buried permeable concrete is provided integrally, and the workability is extremely good for both transportation to the site and construction at the site. After the construction, rainwater flowing in the direction of the road shoulder due to the cross slope inside the drainage pavement is led to the water collecting section, and a continuous water transmission pipe is buried in the water collecting section. Therefore, rainwater can be surely and quickly drained to a catchment basin without clogging with time.

[0006]

[Embodiment of the invention]

 The first embodiment shown in FIGS. 1 to 3 is a concrete product 1 for collecting and draining water having a substantially L-shaped cross section, which comprises a main body portion 2 made of ordinary concrete and a permeable member provided at a corner on the lower roadway side. This is a configuration in which the water collecting part 3 made of concrete is integrated. The water collecting section 3 is buried with a water guide pipe 4 composed of a perforated PVC pipe. The water guide pipe 4 is not particularly limited as long as it can guide water from the side peripheral surface, and may be, for example, a spiral pipe or a punched metal formed into a cylindrical shape. In the figure, 5 is a hanging metal fitting, 6 is open ascon, and 7 is ordinary asphalt.

The production of the concrete product for collecting and draining water 1 may be carried out by a usual process. For example, an example of a prototype is shown below. 1. Formwork set, 2. 2. Body part 2 (ordinary concrete) casting; 3. Body part 2 surface iron finish; First curing, 5. 5. removal of formwork; 6. Installation of perforated PVC pipe (headrace pipe 4) 7. Water collecting section 3 (permeable concrete) 8. Water collecting part 3 surface iron finish; Second curing, 10. Demolding In addition, 4. In the first curing step, since it was in the cold season, weak steam curing was applied (about 40 ° C. after 2 hours). Also, 5. In the process of removing the formwork, the concrete was hardened enough to allow the attachment to be removed, and removed (approximately 3 hours and 30 minutes after casting).

Since the concrete product 1 for collecting and draining water having such a configuration is a single member (integrated product), it is easy to manage the product and transport it to the site. Since it is only necessary to arrange it in contact with the open ascon 6), compared to the conventional method of burying a water guide pipe and collecting and draining water, it requires much more work for product management, transport to the site, and construction at the site. It is good. In the state after the construction as shown in FIGS. 1 and 3, the rainwater flowing in the direction of the road shoulder by the transverse gradient inside the drainage pavement (open granulated ascon 6) is guided to the water collecting part 3, Since the water collecting pipe 3 is buried in the water collecting section 3, the concrete products 1 for collecting and draining water are arranged in series in the longitudinal direction, so that the water collecting section 3 and the water collecting pipe 3 are arranged. The pipes 4 are also connected in series in the longitudinal direction, so that rainwater can be surely and quickly drained to a catchment basin (not shown) without clogging with time.

The concrete product 1 for collecting and draining water of FIGS. 1 to 3 which is the first embodiment can be used specifically as an apron, a precast street culvert, and a concrete L type. Therefore, when it is used as an apron, it should be installed after the foundation material and U-shaped groove have been constructed, and when it is used as a precast culvert, it should be placed on the pedestal base pedestal and culvert base. What is necessary is just to arrange | position, In short, what is necessary is just to implement the conventional construction. In addition, the height of the raised portion of the main body 2 may be adjusted to be low as appropriate for pedestrian crossing and wheelchair entry.

A second embodiment shown in FIG. 4 is a V-shaped groove 8, a main body 9 made of reinforced concrete having a shallow V-shaped groove formed on the surface thereof, and a V-shaped groove 8 at a corner on the lower roadway side. The water collecting part 10 made of permeable concrete is provided as a single unit. In the water collecting part 10, a water guide pipe 11 composed of a perforated PVC pipe is buried.

A third embodiment shown in FIG. 5 is a sidewalk roadway boundary block 12, which is composed of a body 13 made of ordinary concrete and a water collection made of permeable concrete provided at a corner on the lower roadway side. This is a configuration in which the unit 14 and the unit 14 are integrated. A water guide pipe 15 made of a spiral pipe is buried in the water collecting section 14.

Although the present invention has been described based on the embodiment, the present invention is not limited to the above-described embodiment, and may be implemented in any way unless the configuration described in the claims for utility model registration is changed. Can be implemented.

[Effect of the invention]

 In short, the present invention is based on a permeable concrete in which a water pipe is buried at the corner on the underside roadway side of concrete products such as reinforced concrete L-shaped, pedestrian road boundary block, precast culvert, apron, V-shaped groove, and dish-shaped groove. The water collection section is made of a single material, and since it is a single member, product management and transport to the site are easy, and the workability at the site is excellent. After the concrete product for collecting and draining water according to the present invention is installed, the rainwater flowing toward the shoulder by the cross slope inside the drainage pavement is led to the collecting part. Since the water guide pipes continuous in the direction are buried, rainwater can be reliably and quickly drained to the catchment basin or the like without causing clogging over time. Therefore, the drainage function can be maintained for a long period of time.
