Description

An ecological rainwater collection system

technical field

The utility model relates to the technical field of environmental protection and ecology, in particular to an ecological rainwater collection system.

Background technique

With the continuous progress of society, people's awareness of environmental protection and resource reuse is gradually increasing. As a country with serious shortage of water resources, my country's per capita water resources are only a quarter of the world's per capita possession, and the annual rainfall deviates. It is easy to lead to irregular droughts and floods in some areas. How to effectively use rainwater, through reasonable collection and utilization, reduce urban flood peak flow, improve the urban ecological environment, and alleviate the tension of water resources, etc., has an important social responsibility. The traditional ecological rainwater collection device is a water pipe for rainwater collection, and the outlet of the water pipe is connected with the urban rainwater collection device. On rainy days, the rainwater enters the urban rainwater harvesting device directly through the water pipe. However, because rainwater generally flows from the road to the water pipe, the rainwater is dirty, and even if the rainwater is collected, it needs to be purified by a purification device before it can be reused, which is costly and cumbersome to operate. It is difficult for the ecological rainwater harvesting system to purify rainwater by itself. Therefore, how to improve the rainwater purification effect of the ecological rainwater harvesting system and make due contributions to the construction of urban sponge cities is a technical problem to be solved urgently by those skilled in the art.

A Chinese utility model patent with a publication number of CN203866895U has been retrieved, which discloses an ecological rainwater collection system, including an ecological ditch, a blind pipe, a catheter and a seepage overflow well. In the overflow well, the water inlet of the guide pipe communicates with the inner cavity of the seepage overflow well, the water outlet end of the blind pipe is lower than the water inlet of the guide pipe, and the bottom of the seepage overflow well is provided with Water seepage structure, the ecological ditch includes a gravel layer, a planting soil layer and a coarse sand cushion between the gravel layer and the planting soil layer, the blind pipe is located inside the gravel layer, the The lower surface of the gravel layer is bonded to the plain soil on the ground.

However, the blind pipe of this ecological ditch is directly connected to the interior of the gravel layer. Once the earth’s crust shakes slightly, there will be gaps in the gravel layer for the coarse sand in the coarse sand cushion to pass through, and the dead pipe will be easily blocked. , resulting in the inability to store water, and the entire system will lose its function. At the same time, this kind of blind pipe is installed deep in the ground, so it is very inconvenient to clean and maintain. Therefore, it is very necessary to solve the problem that the blind pipe is easy to be blocked.

Utility model content

The purpose of the utility model is to provide an ecological rainwater collection system, which has the advantage that the blind pipe is not easy to be blocked.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: an ecological rainwater collection system, including an ecological ditch for collecting rainwater, the ecological ditch includes a surface vegetation layer, a sandy filter layer, a sandy filter layer, A plastic anti-blocking board and a drainage layer, the drainage layer is provided with a plurality of blind pipes for drainage, the upper ends of the dead pipes are connected to the plastic anti-blocking board through a plurality of connecting pipes, and the plastic anti-blocking board is provided with There is a through hole for the connecting pipe to be inserted and water to flow in, and the water inlet of the through hole is provided with a filter assembly for blocking sand and gravel.
