JPS595065Y2 - Underground drainage block device - Google Patents

Description

[Detailed description of the invention] This invention relates to a block device for collecting and draining groundwater near the surface of the earth.

Up until now, permeable circular pipes have generally been buried near the ground surface to treat water that accumulates near the ground surface, but circular pipes have a small collection surface for water that mainly enters into the ground from the topsoil. Ivy has a defect of poor water efficiency.

This proposal was made in view of the above circumstances, and will be explained below using the examples shown in the drawings. In Fig. 1, 1 is a bottom slab made of waterproof concrete, and the lower groove part 1b is bordered by the central ridge base 1a. , IC are formed, and rising walls 1f, Ig are formed at the outer ends of the outer ridge bases 1d, le.

2 is the printing plate, and its front width is the rising wall If.

1g, and upper groove portions 2b and 2C corresponding to the lower groove portion 1b and IC of the bottom plate 1 are provided with the center downward wall 2a as a boundary, and these upper and lower groove portions 1b, 2b, 1
C and 20 are in the form of drainage canal H.

The proposed block device is constructed as described above, but in order to use it now, the bottom plate 1 must be assembled as shown in FIGS. 3 and 4.
and Plate 2 are combined and buried underground near the ground surface.

Then, the water that accumulates near the ground surface is caught by the flat plate surface of the permeable concrete plate 2 as a water collection surface, and flows into the drainage channel formed by the upper and lower grooves 1b and 2b, IC, and 2C of the bottom plate 1 and plate 2. They are guided and drained one after another.

As described above, this project is capable of dynamically collecting and draining water that seeps down from the ground surface using a wide catchment surface, and is effective by burying it underground near the ground surface, such as in grounds and cords. This allows for ground surface management.

Furthermore, it is also superior to circular pipes in terms of stability after construction.

Claims (1)

[Scope of utility model registration request] Consisting of a bottom plate 1 made of waterproof concrete and a plate 2 made of water-permeable concrete, the bottom plate 1 has a central ridge base 1a as a boundary, a lower groove 1b and an IC, and the outside of the outer ridge bases 1d and le. A rising wall 1f, Ig is formed at the end, and the front width of the printing plate 2 is such that it fits tightly into the rising wall 1f, 1g, and the bottom groove 1b, IC
This underground drainage block device is provided with upper groove parts 2b and 2C corresponding to the upper groove parts 2b and 2C, and drains underground collected water that has permeated from the printing plate 2 through a drainage channel H formed by the upper and lower groove parts 1b and 2b, 1C and 2C.
