Urban landscape rainwater reservoir system

Abstract

The invention provides an urban landscape rainwater reservoir system. The urban landscape rainwater reservoir system comprises a rainwater collection pipe and a rainwater collection tank. One end of the rainwater collection pipe is connected with a roof drainage pipe or a drainage ditch, and the other end of the rainwater collection pipe is connected with a filter well. The filter well is connected with a sediment well through a water supply pipe. The sediment well is connected with the rainwater collection pipe through the water supply pipe. The filter well, the sediment well and the rainwater collection tank are all arranged under the soil. The rainwater collection tank comprises a plurality of rainwater collection tank units. The plurality of rainwater collection tank units are closelyconnected to form a honeycomb structure. Each rainwater collection tank unit is provided with at least two first through holes. The first through holes communicate to form a water flow channel. The rainwater collection tank communicates with a municipal water supply network through the water supply pipe. Compared with the prior art, the urban landscape rainwater reservoir system. The urban landscape rainwater reservoir system has the advantages that the problems that the rainwater collection tank is blocked, and the water storage volume ratio is low and the structure bearing capacity is poor can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of urban rainwater collection and utilization, in particular to an urban landscape rainwater storage tank system. Background technique [0002] At present, many countries in the world are vigorously developing the technology of rainwater recovery and reuse. Whether in developed countries (such as the United States, Japan, Canada, and European countries), or in developing countries such as India, Thailand, etc., rainwater harvesting and recycling technologies are used as important methods to relieve water pressure. In foreign countries, there are mainly three systems for rainwater collection and utilization: ①rainwater collection and storage system; ②ecological rainwater system; ③rainwater infiltration system. Rainwater from streets and arterial roads flows to both sides of the road, enters the reservoir through sewers, and can also replenish groundwater through infiltration. The above systems are relativel...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the present invention provides an urban landscape rainwater storage tank system, which innovatively uses regular hexahedron-shaped rainwater collection tank units to form a honeycomb structure. , it uses less material than the unit module of the rainwater collection pool of the cube, which can effectively solve the problems of low water storage volume ratio and poor structural load-bearing capacity of the rainwater collection pool. The problem of blockage of rainwater collection tanks reduces maintenance costs
