Rainwater collecting and recycling construction method applied to sponge city

Abstract

The invention discloses a rainwater collecting and recycling construction method applied to a sponge city. The construction method includes the steps of step 1, site selection of a water storage area;step 2, foundation pit treatment; step 3, reservoir establishment; step 4, circulating system establishment; and step 5, foundation backfilling and ground surface treatment. According to the rainwater collecting and recycling construction method applied to the sponge city, the construction method is reasonable in design, clear in construction procedure, simple and reliable in construction steps,proper in step connection arrangement, high in quality, and capable of effectively guiding urban rainwater to permeate into the ground, so as to achieve the effect of fully recycling the rainwater, accelerating rainwater infiltration, and preventing water accumulation on the road surface. Meanwhile, the rainwater can be effectively percolated, purified, collected and conserved, the water quality is improved, an underground stored water source is improved, and surface water is conveniently recycled, which increases the water source utilization rate, and supplements urban water; and different water qualities are obtained through different treatment modes and applied to different aspects, so that the surface water is more reasonably and thoroughly utilized, and rainwater resource utilizationand ecological environment protection are promoted.

Description

technical field [0001] The invention relates to the field of karst cave treatment in tunnel construction, in particular to a rainwater collection and recovery construction method applied to sponge cities. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge, and has good elasticity in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city"; The international general term is "low-impact development rainwater system construction", which absorbs, stores, infiltrates, and purifies water when it rains, and releases and utilizes the stored water when needed, so as to realize the free migration of rainwater in the city and make buildings and communities Roads and squares, parks and green spaces, water systems, etc. have the functions of absorbing, storing and slowing down the release of rainwater, improving the fu...

[0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge, and has good elasticity in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city"; The international general term is "low-impact development rainwater system construction", which absorbs, stores, infiltrates, and purifies water when it rains, and releases and utilizes the stored water when needed, so as to realize the free migration of rainwater in the city and make buildings and communities Roads and squares, parks and green spaces, water systems, etc. have the functions of absorbing, storing and slowing down the release of rainwater, improving the function of urban ecosystems and reducing the occurrence of urban flood disasters. Taking strong drainage measures did not solve the root cause of urban waterlogging, and to a certain extent, the environment was affected. At the same time, rainwater was not effectively stored, resulting in waste of water resources. For this reason, we propose a rainwater that is applied to sponge cities Collection and Recycling Construction Method
