Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is used to improve the surrounding land environment by returning water that has been collected as a stream or a water reservoir as surrounding groundwater, and to collect and drain humid groundwater. This relates to permeable waterways developed for the purpose of improving humid environments.

<Conventional technology> In order to return some of the water running through waterways underground, methods such as using concrete waterway blocks with holes drilled in them or paving the bottom of the waterway with crushed stones have been used. ing.

<Problems to be solved by the invention> However, even if holes are made in a concrete waterway block, it is not possible to increase the porosity, and if the pores are small, the perforation will be difficult and one capillary will be reduced from g. It is not possible to normally expect water to flow due to this phenomenon, and the method of paving crushed stones in a part of the waterway has a low structural strength, so it is not practical as it loses its resistance and is washed away when the water flow increases. It has some disadvantages.

Means for Solving the Problems〉 Therefore, 1. the present inventor developed a structure in which the side or bottom of a waterway is formed of a water-permeable inorganic block having a large number of pores, most of which have a diameter of 0.5 to 5 m. He developed the waterway □.

If the pore diameter of the water-permeable inorganic block is less than 0.5 m, it will become clogged and impair its water permeability, and if it is more than 5+n++, the water permeability will be excessive and it will lack versatility as a water collection channel. I can't.

In the water-permeable inorganic block (2), most of the pore diameters, for example, 60% or more, need only be around 0.5 to 5 m, and inorganic particles with a main particle diameter of 1 to 15 mo, such as natural waxite There is a method of bonding between the particles by heating ore, crushed bricks, crushed fired clay, etc. that can be collected in a molten metal to the melting point using a lower temperature molten material (e.g. feldspar, glaze, etc.). A block is formed by using an inorganic adhesive or by utilizing the adhesive properties of an inorganic or organic polymeric material (for example, a phenol resin or an asphalt material). In addition, a block in which particles with different diameters are unevenly distributed on the surface side and back side of the block (Japanese Patent Application No. 62-26847
) can also be used as appropriate depending on the purpose.

Forming the sides or bottom of a waterway with a water-permeable inorganic block as used herein does not only mean that the entire side or bottom of the waterway is formed with a water-permeable inorganic block;
It also means using a water-permeable inorganic block in the form of an island on a part of the side or bottom of the waterway. In addition, in the construction of waterways,
Regarding the joint structure and reinforcement necessary for strength, the measures implemented in conventional waterway blocks can also be implemented in the present invention.

Furthermore, in small-scale waterways, it is also included to form waterways with integrally molded U-shaped blocks or similarly shaped water-permeable blocks.

<Function> With such a structure, when the land around the waterway has a humidity condition that allows water to be absorbed by the permeable inorganic blocks that make up the waterway, water passes through the many pores and absorbs water from the inside of the waterway to the nearby land. Conversely, when the surrounding land is humid, it collects and drains water from underground, helping to create a humid environment. Such an effect is observed when the pore size is 0.5 to 5.
This is due to the movement of water through the pores of m due to capillary action.

<Example> Embodiments of the present invention will be described in detail below with reference to the drawings.

1 to 3 are cross-sectional perspective views showing embodiments of the present invention, respectively.

FIG. 1 shows a first embodiment of the invention. In this example, when constructing a waterway (1), inorganic blocks (2), which are entirely water-permeable, are placed at predetermined intervals and then concrete is poured to integrate them. The water flow function is maintained internally by using sink stones (3) on the sides and bottom of the waterway.

FIG. 2 shows a second embodiment of the invention.

In this example, a water channel (1) is constructed of a water-permeable inorganic block (2) whose peripheral edge is bordered in a porous state. Almost the entire waterway is permeable.

FIG. 3 shows a third embodiment of the present invention.

In this example, almost the entire water channel (1) is formed of a water-permeable inorganic block (2). Almost the entire waterway is permeable. Reinforcements (4) are placed at appropriate intervals for reinforcement.

<Effects of the Invention> Since the present invention has the above-described structure, when the land around the waterway has a humidity condition that allows it to absorb water, water is supplied from the inside of the waterway to the nearby land through the large number of pores. On the other hand, when the surrounding land is humid, collecting and draining water from underground has the effect of creating a humid environment.
