Description

DETAILED DESCRIPTION OF THE INVENTION [Fields of application of the present invention] This invention relates to water-permeable pavement blocks laid on roads.

Conventional technology> The stone blocks used for the two sidewalks in parks and amusement parks are designed with colorful colors that harmonize with the natural environment and the sides of the blocks.
By singing together and distributing the load, it can be used not only for road closures but also for roadways.
A block similar to that of the I2 river has been under development. However, since the top surface of the block is impermeable, water that falls on the top surface of the block is treated as before by being drained into underground water pipes.

<Problem to be solved by the invention> What is the amount of water discharged into the sewer pipe by infiltrating underground VC through the permeable surface of constructed paving stone blocks? By reducing this, it will be easier to prevent water damage caused by overflowing small rivers, take measures to green streets and parks, and secure underground water through rainwater rebound.

Measures to solve the problem: Water draining underground on impermeable paving concrete blocks by installing permeable water holes such as salt water holes and porous holes to drain water underground. V
This invention r [, $ 111 fill] Sokeishi flock yrl which can completely distribute the load by interlocking the bases with each other.With its bright colors, it is attractive for promenades, car seats, etc. A saline hole or porous hole is installed to allow rainwater to permeate into the impermeable concrete layer to create a celebratory effect (8).
Busy ゛C Water seeps underground and drains into the sewer 1' IτSlowly C Iku 11T Prevent the flooding of small and medium-sized rivers around the area, and at least prevent artificial streams from falling on the trees and flowers in the park. It is possible to secure underground water without having to supply water, making it possible to reduce the risk of marginalization.

<Implementation sequence> Figure 1 is a diagram showing the execution sequence of blocks formed with the hard-mixed concrete of this invention. Here, hard-mixed concrete is referred to as cement, resin, various fiber materials, etc. 911111 with a water hole for water permeation in the ol which contains composite concrete mixed with a base material after raising the gold.
[2 is a symmetrical saw-toothed side and 3 is a parallel S-shaped 1fl
During construction, the contact surfaces of the blocks that are in contact with KN are more effective than conventional blocks, and the friction between the blocks works and meshes, resulting in a M-sized force distribution that prevents lateral movement or any twisting. Therefore, it has resistance to the applied load that acts on the sheathing.

The NiI side 4 of the block is covered with a colorful, wear-resistant, water-resistant concrete layer.

Depending on the area to be constructed, such as the Kokoto land or the airport, it is recommended to use a high-strength composite concrete with six sides or all layers mixed with resin and fibers. .

In this way, Hon@mei's salt water block is coated with concrete that increases strength, so compared to conventional water-permeable blocks, it can be installed not only in parks and promenades, but also in general weight-bearing roads and general passageways in residential areas. The monkey is the one who does it.

In addition, as shown in Figure 3, for the permeable surface, in the case of depressions where no large loads are applied, a salt water hole 1 is installed in the upper part 5, and a porous concrete layer Pt is formed in the lower part 6 to direct rainwater to the underground V 2fL.
V-rubbing or bolus concrete h1 as shown in Figure-4
Depending on the construction location and fall conditions, YC ratio, etc., M P k is laminated vertically in the middle of impermeable concrete with salt water holes on the top and bottom.
If the number of irrigation holes and the thickness of the Bohus layer are quadratic, then it becomes 0.
<Young Red of the Invention> When the block of the present invention is installed, rainwater can be diverted underground by 12X without draining water from the water collection basin to the sewer as in the case of today. Tree of the Tree Emperor,
jL Replenishes essential water over a long period of time without artificially supplying water to the flowers.Hμ of the mountain water that fell on the city's shield area, such as in the 1st and 8th heat of the year, regenerates underground, resulting in small and medium-sized plants. It is also possible to prevent flood damage by reducing the amount of water in rivers.
