Description

[Detailed description of the invention] 1. Purpose of the invention The invention relates to a device for rainwater infiltration into soil.

Today, the amount of water in rivers is increasing because rainwater is centrally managed in houses and other buildings and immediately drained into the sewer system, and rainwater on paved roads is immediately drained from side gutters into the sewer system. death,
During heavy rains, it caused river flooding. For this reason, rivers and river basins were being repaired, but this alone was insufficient as a flood control measure.
It was also a cause of groundwater depletion and land subsidence.

Therefore, the purpose of the present invention is to centrally manage rainwater and allow it to permeate into the soil instead of discharging it into the sewer system, thereby eliminating the above-mentioned drawbacks. .

2. Structure of the invention The structure and operation of the invention will be explained with reference to the embodiments shown in the drawings.

1 and 1 are rainwater storage tanks installed at intervals inside a groove a formed with a predetermined length, width, and depth in the land surrounding a predetermined building; Openings 2, 2 are provided on one side of the housing. Reference numeral 3 denotes a mesh pipe installed in a gentle curve between the reservoir openings 2 and 2, and this mesh pipe has sufficient strength to withstand strong pressure.

Reference numeral 4 denotes a filter membrane body which is removably inserted into the mesh pipe 3, and this filter membrane body has a relatively dense mesh material 5 attached to its inner side and a relatively coarse mesh material to its outer side. Attach the net material 6, and connect these three members 4, 5,
6 is constructed by integrally machine-stitching and has flexibility as a whole. The inner mesh material 5 serves as a breaker to prevent various floating matters and sludge mixed in rainwater from coming into direct contact with the filtration membrane body 4 and reducing its permeability, and the outer mesh material 6 serves as a breaker for preventing various floating matters and sludge mixed in rainwater from directly contacting the filtration membrane body 4 and reducing the permeability.
It is made of the same material as the mesh pipe, and is made of the same material as the mesh pipe.

b is crushed stone, c is sand, and d is topsoil.

Therefore, the openings 2, which are opposite to each other in the reservoirs 1, 1, installed at appropriate intervals on the land surrounding a predetermined building.
A mesh pipe 3 is installed between the two parts while forming a gentle curve. When initially constructing the mesh pipe 3, the filter membrane body 4 with mesh materials 5 and 6 attached to the inside and outside may be inserted into the inside of the mesh pipe 3. However, when replacing the filter membrane body 4 after installation, this can be inserted into the mesh pipe 3. Remove it and replace it with a new one.

The rainwater that has now flowed from the rain gutter on the roof and been collected in the storage basins 1, 1 flows from the openings 2, 2 into the filter membrane 4, respectively, and flows out into the soil through the outer mesh pipe 3, but before this outflow. The rainwater is filtered by the inner mesh material 5 of the filter membrane body 4 to remove foreign matter and sludge mixed in the rainwater, and is filtered by the filter membrane body 4, so that the water becomes clean and passes through the outer mesh. material 6 and mesh pipe 3
It penetrates into the soil through the

3 Effects of the invention This invention forms a groove a of a predetermined length, width, and depth at the location, and the openings 2 of the reservoirs 1, 1 are installed at intervals in the groove.
A mesh pipe 3 is buried between the two parts, and a filter membrane body 4, which is integrally provided with a relatively dense mesh material 5 on the inside and a relatively coarse mesh material 6 on the outside, is removably installed in the mesh pipe. Since the device is characterized by
Rainwater that falls on the roof of a building will be able to reliably and quickly percolate into the soil of the land without being directly discharged from the storage tank to the sewer system, thereby preventing the concentrated outflow of rainwater into rivers. Second, the rainwater that permeates into the soil becomes clean water from which all foreign matter and sludge have been removed, so soil with good permeability can be maintained for a long period of time. Thirdly, when the filtration membrane body and its surrounding inner and outer netting become clogged, it can be easily replaced and used, which has great practical effects. be.
