Groundwater replenishment water collecting device

The invention relates to a groundwater replenishment water collecting device, in particular to a groundwater replenishing water collecting device which can effectively replenish the ground layer groundwater and adjust the flood peak water flow to avoid the ground area water.

According to the excessive construction of urban buildings, the earth water circulation system has been seriously damaged, causing frequent news of flooding and flooding in various areas during the rainy season or typhoon, and reducing the incidence of urban flooding has become an important issue.

The traditional building base mainly adopts the design of impervious pavement, and then installs drainage ditch on the adjacent ground, in order to drain the rainwater to the sewer system as soon as it rains. However, the existing building base and its surrounding land are impervious. The rainwater can not seep into the ground, and the earth loses its ability to absorb water and retain water. The drainage function of the drainage ditch is limited, and there are often fouling conditions, which can cause the rainwater to be discharged in a timely manner. It is also the main cause of urban water accumulation, and the other is rainwater drainage. After the ditch enters the sewer system, it will be discharged into the river or the sea, and it will not penetrate into the ground soil, which will cause the groundwater to be irreparable and the ground subsidence, and it will be more difficult to adjust naturally because the groundwater in the earth is gradually decreasing. The temperature function makes the urban environment prone to high temperature "heat island effect".

Therefore, today's governments all advocate green buildings, including base greening, building base water retention, rainwater recycling and reuse, etc., in the construction base water conservation, it will be the building base A water injection pipe is buried in the surrounding land, and concrete is laid on the land around the nozzle of the water injection pipe. The permeable pavement is laid on the nozzle and concrete of the water injection pipe. Thus, when it rains, the rainwater can flow into the water injection pipe through the permeable pavement. Then, it flows into the soil through the water injection pipe to achieve the function of draining and replenishing the groundwater around the building base. However, in actual use, it was found that whenever the rainy season or typhoon comes and there is abundant rainfall, the rainfall is greater than the displacement of the water injection pipe, so the water injection pipe is often not drained, so that every time the rainy season or the typhoon comes, the water is accumulated everywhere. The situation of disasters still occurs frequently.

The reason is that the present inventors have made it possible to solve the problem of manufacturing and designing in related fields for many years, in view of the fact that the method of water injection pipe is only buried in the land surrounding the building base, and the water shortage is too large to be solved. With the help of knowledge, and through many ingenuity, research and development on the existing urban building water accumulation, and research and development of the present invention.

A permeable pavement is laid on the earth leakage layer, and a plurality of convex portions are continuous on the bottom side of the permeable pavement, and the convex portion of the permeable pavement is in contact with the permeable layer through the anti-earth leakage layer.

The groundwater replenishment water collecting device as described above, wherein the convex portion of the permeable paving is further provided with one end of the water collecting pipe, and the other end of the water collecting pipe extends into the water permeable layer.

The groundwater replenishment water collecting device as described above, wherein the permeable paving is composed of a plurality of permeable bricks, and a part of the permeable bricks is thicker than the adjacent permeable bricks to form a convex portion of the permeable paving.

In the groundwater replenishing water collecting device as described above, the water injection hole of the water tank of the water storage tank is further inserted with a water injection pipe, and a plurality of through holes are formed in the water injection pipe peripheral wall.
