Water storage system used for river-alongside road of sponge city and construction method

Abstract

The invention discloses a water storage system used for a river-alongside road of a sponge city and a construction method. The water storage system comprises a water seepage pond and a water storage pond; a collection water pipe is arranged between the water seepage pond and the water storage pond; the water seepage pond comprises a water permeable surface, a clay layer and a gravel layer; the water permeable surface comprises a water permeable pavement layer, a leveling layer, a water permeable base layer, a permeable layer and a water permeable cushion layer; a first water discharging pipe is arranged in the water permeable base layer; a second water discharging pipe is arranged at the bottom of the gravel layer; the first water discharging pipe and the second water discharging pipe are communicated with the collection water pipe respectively. The construction method comprises the following steps: (a) digging a foundation pit; (b) constructing the water storage pond; (c) constructing the water seepage pond; (d) constructing the water permeable surface; (e) curing. The water storage system is simple to construct and convenient to operate; the construction quality is easy to control, the construction cost is low, the permeation effect is good and the water storage capability is strong; collected rainwater is purified and secondary pollution of the rainwater is reduced.

Description

technical field [0001] The invention relates to a water storage system and a construction method for a road along a river in a sponge city. 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. It can also be called "water elastic city". Absorb water, store water, infiltrate water, purify water when needed, and "release" the stored water and use it when needed. Under the premise of ensuring the safety of urban drainage and waterlogging, the sponge city maximizes the accumulation, infiltration and purification of rainwater in the urban area, and promotes the utilization of rainwater resources and the protection of the ecological environment. [0003] The traditional sponge city construction model is full of hardened roads. Whenever there is heavy rain, it mainly relies on "grey" facili...

Problems solved by technology

Whenever there is heavy rain, it mainly relies on "grey" facilities such as pipes, canals, and pump stations to drain water. The main planning and design concepts are "quick drainage" and "end-centralized" control. Rainwater is mainly drained through drainage facilities and cannot penetrate into the ground. It will cause waterlogging every time it rains, and the drought and flood will turn sharply, which does not meet the requirements of sponge city construction
