Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a block laid on a road, a passage, a park, and the like, and more particularly, to a water-permeable block suitable for use on a road, a passage, and the like in a green belt or the like where vegetation needs to be maintained. .

[0002]

2. Description of the Related Art In recent years, as roads are paved and soil around the roads becomes dry, the growth of trees and the like is hindered. I have. In this way, the natural environment has been significantly degraded, and especially the ecosystems have started to have a great impact, so now we have to install permeable blocks that are useful for environmental protection on roads such as national roads and prefectural roads or on all paved surfaces, etc. It must be used to create a naturally friendly environment.

[0003] Here, the conventional water-permeable block is formed of porous water-permeable concrete, and rainwater permeates through the air bubbles of the block into the ground.

[0004]

However, the conventional water-permeable block has a certain limit in the amount of water permeation because rainwater penetrates into the ground by penetrating the air bubbles in the water-permeable concrete. There is a problem that the amount of water cannot be increased until the drying of the soil as described above is sufficiently eliminated.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a water-permeable block capable of greatly increasing the amount of water permeation.

[0006]

Means for Solving the Problems To solve the above-mentioned problems, a means adopted by the present invention is to provide a block laid on a road, a passage, a park, or the like, which is provided with a water permeable hole that passes from the front surface to the back surface. It is in. By this means, water permeability is not determined based on the characteristics of the material itself, but a large amount of rainwater can be transmitted through the ground by opening a water-permeable hole. For example, the block is made of any one of concrete, asphalt, plastic, and ceramic.

[0007] Preferably, the block has a hollow portion,
Since the water permeable holes pass through this hollow portion, the hollow portion temporarily retains rainwater and provides a habitat for microorganisms that require the presence of water and air. For example, by filling the hollow portion with fibers, it becomes easier for microorganisms to inhabit. Also, by packing activated carbon, it purifies rainwater, removes dioxin, etc., and returns it to the underground.

[0008] More preferably, the block is solidified with a reinforcing material to secure sufficient strength. For example, the reinforcing material is a frame formed of one of metal, plastic, ceramic, or a composite material in which two or more are combined, or formed by attaching a reinforcing mesh to a plurality of reinforcing bars above and below. It is a reinforcing bar frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of a water-permeable block according to the present invention will be described with reference to FIG. Figure 1 shows the road,
1 shows a most basic permeable block 1 for laying in a passage, a park, or the like. The block 1 has a large number of water permeable holes 2 that pass from the front surface to the back surface. Therefore, the block 1 can directly guide the rainwater that has fallen to the ground, and can supply an incomparably large amount of water to the surrounding soil as compared with the conventional permeable block. Generally, ordinary concrete is used as the material of the block 1. However, when strength is particularly required, high-strength concrete is used. For a road with a light load, such as a pedestrian-only road, concrete suitable for the road may be used.
As described above, as the material of the water-permeable block 1, it is not necessary to use a water-permeable concrete having a relatively low strength because it is porous, and it is possible to freely select a type of concrete according to a place where the water-permeable block 1 is laid.

If a reinforcing material such as a reinforcing bar frame similar to that shown in FIG. 3 is put inside and solidified integrally, the strength can be further increased. Further, as the material of the block 1, not as concrete but also strong asphalt, plastic, ceramic or the like can be used.

[0011]

A second embodiment of the water-permeable block according to the present invention will be described with reference to FIGS. As shown in FIG. 2, the water-permeable block 5 has a large number of water-permeable holes 6 passing from the front surface to the back surface, and has a hollow portion 7 formed therein, as in the case of the first embodiment. Through the hollow portion 7, the material escapes from the front surface to the back surface. As shown in FIG. 3, the block 5 is provided with reinforcing steel frames 8 formed by attaching reinforcing steel meshes 10 above and below a plurality of reinforcing steel columns 9 so as to sandwich the hollow portion 7 as shown in FIG. It is solidified together. The reinforcing bar 9 and the reinforcing bar mesh 10 are made of a material having corrosion resistance. Since the hollow portion 7 is surrounded by the reinforcing frame 8, sufficient strength is ensured even if the hollow portion 7 is provided.

The hollow portion 7 is filled with fibers 11 and activated carbon 12 which are water-permeable and corrosion-resistant and promote the inhabitation of microorganisms from an opening on a side surface (not shown) of the block 5.
If necessary, microorganisms particularly effective for soil improvement are attached in advance. The hollow part 7 temporarily holds a large amount of rainwater, and is useful not only for greening but also for preventing flooding of rivers.
The presence of water and air inside provides a good habitat for microorganisms. Propagation of microorganisms improves the soil around the plant and contributes to greening. Further, by filling the hollow portion 7 with the fibers 11, the microorganisms can be more easily propagated. Further, by filling the hollow portion 7 with activated carbon, it is possible to purify rainwater that has flowed in, remove dioxins, and the like, and reduce the underground water. This block 5 can provide an earth-friendly construction method.

As the reinforcing material, the above-described reinforcing bar frame 8 is used.
Alternatively, a frame formed of any one of metal, plastic, and ceramic or a composite material obtained by combining two or more of them can be used. Block 5
Instead of concrete, strong asphalt, plastic, ceramic, or the like can be used as the material for the above.

[0014]

As described in detail above, the water-permeable block of the present invention is provided with a water-permeation hole which passes from the front surface to the back surface in a block laid on a road, a passage, a park or the like. Therefore, the amount of permeation of rainwater or the like into the ground can be remarkably increased, and an excellent effect of greatly helping greening of roads and the like is exerted.

[0015] Preferably, a hollow portion is provided, and the water permeable hole passes through the hollow portion, so that it is possible to temporarily retain rainwater and to promote the propagation of microorganisms essential for soil improvement. Further, by filling the hollow portion with fibers or activated carbon, soil improvement and accompanying greening can be more effectively performed.
