Rainwater Utilization System and Construction Method

Abstract

The invention discloses a rainwater utilization system and a construction method, in particular to a rainwater collection and utilization and staggering peak discharge device and a construction method. The rainwater utilization system is characterized by comprising a pure water pool, and a flood adjustment pool which is arranged above the pure water pool and can guide rainwater into the pure water pool, wherein a pure water pool supporting body and a flood adjustment pool supporting body which are built by concrete water reservoir building blocks are respectively arranged in the pure water pool and the flood adjustment pool; the flood adjustment pool supporting body is connected with a gravel water flow channel; an inspection well penetrating through the pure water pool supporting body and the flood adjustment pool supporting body is arranged; a water pump chamber is arranged at an outlet of the inspection well; each concrete water reservoir building block is a hollow building block; a rectangular hole penetrating through in a vertical direction is formed in the middle part of each concrete water reservoir building block; semi-square slots penetrating through in the vertical direction are formed in two end parts of each concrete water reservoir building block. The rainwater utilization system disclosed by the invention is simple, relatively low in construction and use cost, wide in application range and favorable for rainwater collection and purification and can effectively alleviate urban rain flood disasters.

Description

Technical field: [0001] The invention relates to a rainwater utilization system and a construction method, which is a rainwater collection utilization and peak shifting discharge device, belonging to the technical field of sponge city construction. Background technique: [0002] At present, with the popularization of the concept of environmental protection, people pay more and more attention to the collection and utilization of rainwater, and one of the important facilities for rainwater collection and utilization is the rainwater collection pond. Traditional rainwater collection tanks are mostly made of concrete. Due to their high cost, long construction period, and great damage to the environment, they have been gradually replaced by rainwater collection tanks based on plastic modules. The plastic module rainwater collection tank is assembled into a large cube by a large number of identical hollow hexahedral box modules, and the outside of this large cube is wrapped with a...

Problems solved by technology

[0007] The shortcoming of above-mentioned three kinds of storage ponds: 1) all belong to the common method of water storage modular rainwater collection pond, and function is single, and the pond of building is either used as storage pond, or is used as osmotic flood control pond, can't combine two kinds of different Functional pools are combined into one; 2) The water storage modules are all made of plastic, and the cost is still very high, making it difficult for many construction units to accept
