Description

[Detailed description of the invention] This relates to a paving method.

Generally, the concrete and asphalt that form the pavement surface are not permeable, so in order for surface water to permeate all underground, the entire surface should be exposed directly to the ground surface, rather than forming the entire surface of the pavement, as is the case around street trees. Alternatively, you can cut out a part of concrete or asphalt to form a cavity where surface water flows directly underground, or cut out a part of a material other than concrete or asphalt, such as a steel plate, to allow surface water to flow underground. This is done by forming a cavity that flows directly into the water. Alternatively, all the concrete blocks were arranged, the joints were filled with sand, and water and gold permeated through the small gaps between them.

In view of the problems mentioned in section 2 above, the present invention has been developed to provide a plurality of concrete flocks each consisting of a concrete block body having a hollow part penetrating vertically and a water-permeable block attached to the top or inside of the hollow part. The concrete block is prepared so that the concrete block body is placed on the ground so that the permeable block faces upward, so that the P1 ground surface can be covered with a paved surface. Moreover, the present invention provides a paving method that allows a large amount of surface water to permeate underground. The present invention will be explained in detail below.

1 to 6 show a first embodiment of the present invention, in which 10 is a concrete block used in the method of the present invention, including a concrete block main body 11 made of a general concrete block material and the concrete block main body 11 made of a general concrete block material. It consists of a water-permeable rectangular plate-shaped block 13 which is overlaid on the upper surface of the concrete block body 11 and integrated by applying concrete mortar or adhesive. 12 are provided.

[Plat-shaped block] 3 is an aggregate of inorganic particles such as silicate and oxide minerals, which is completely fired or bonded together to solidify it so that it has a large number of pores that allow water to pass through but not sand grains. Because the surface is rough, it has greater frictional resistance than conventional pavement surfaces, and has the effect of preventing slips when people are walking or cars are driving. The strength of this plate-like block 13 shall be set depending on the purpose of use, such as for a sidewalk or a roadway.

Next, the paving method will be explained. As shown in FIGS. 5 and 6, a sand layer 14 is laid on the leveled roadbed 15, and the block body 1 of the concrete block 10 described above is placed on top of the sand layer 14.
1 are arranged so that the plate-like blocks 13 are located at the top.

Due to this.

The upper surfaces of the plate-like blocks 13 of the concrete blocks 10 are arranged intertwined with each other to form a paved surface that completely covers the entire ground. Since this plate-like block 13 has water permeability,
As shown by the arrow, surface water due to rainfall flows into plate-shaped block 1.
3 through the hollow part 12 of the concrete block body 11
It passes through the sand layer 14 and permeates underground.

7 to 1o show a second embodiment of the present invention. In the figures, 20 is a concrete block used in the method of the present invention, including a concrete block main body 21 made of a general concrete material and a concrete block main body 21 made of a general concrete material.
It consists of a block 23 made of water-permeable gold which is inserted and fixed into a hollow part 22 which vertically penetrates through concrete mortar or an adhesive.

Next, paving method ff: will be explained. As shown in FIG. 10, a sand layer 14 is laid on the soil of the roadbed 15, and the block body 21 of the concrete block 2o described above is inserted into the soil, and the surface on which the permeable block 23 is fixed is placed on top. Arrange as shown.

As a result, the upper surfaces of the concrete block body 21 of each concrete block 20 and the water-permeable block 23 inserted and fixed therein are arranged flush with each other, thereby forming a paved surface that completely covers the entire ground. When surface water due to rainfall is on the permeable block 23, the water directly passes through the permeable block 23 and reaches the soil, and when it is on the concrete body 21, it flows into the nearby permeable block where it easily flows. It passes through 23 and enters the soil, becoming Kokichi that permeates underground. The other configurations and effects are as described in the first section above.
This is similar to the embodiment.

Further, the shape of the block body and its hollow portion is not limited to the above-mentioned shape, but may be modified into a circular shape, a polygonal shape, etc. Further, the positions and numbers of the cavity portions are not limited to those described above, and various modifications are possible.

J: As explained above, according to the present invention, a plurality of concrete blocks are constructed of a concrete block main body through which a hollow part passes through the vertical part, and a water-permeable block attached to the top or inside of the hollow part. Prepare the concrete block, and place the concrete block so that the water-permeable block faces upward. Since it is placed on the ground, a paved surface similar to conventional pavement forms can be formed easily and quickly. Moreover, a large amount of surface water during rain is absorbed into the ground through the permeable blocks and the cavity. Inside 9
It penetrates into the ground, prevents sewage and river flooding, provides natural replenishment of groundwater, and prevents ground subsidence due to a drop in the groundwater level, providing an environment closer to the natural state, and in all aspects of pavement being the same as conventional pavement. It is extremely versatile and has the ability to maintain the comfort of daily life.
