Circular-permeation and water-storage sponge integrated system

Abstract

The invention discloses a circular-permeation and water-storage sponge integrated system. The system comprises a gravel sponge belt, one or more rows of steel band corrugated pipes, a steel band corrugated pipe communicating groove and multiple rainwater conversion wells arranged at the upper part of the gravel sponge belt, wherein the steel band corrugated pipes and the steel band corrugated pipe communicating groove are arranged in the gravel sponge belt; an inspection well communicated with the overground part is arranged in the steel band corrugated pipe communicating groove; the rainwater conversion wells are communicated with rainwater wells through water inlet pipes and communicated with the inspection well or the steel band corrugated pipe communicating groove through overflow pipes, punched water distribution pipes are connected between the rainwater conversion wells, and ends of the water inlet pipes, the overflow pipes and the punched water distribution pipes are all arranged in the middles of the rainwater conversion wells, and the bottoms of the ends of the punched water distribution pipes are lower than those of the ends of the water inlet pipes and the overflow pipes. According to the system, characteristics of good bearing, permeating filtering and purifying properties and low cost of the gravel sponge as well as characteristics of good water storage performance and high bearing capacity of the steel band corrugated pipes are sufficiently utilized and combined, so that rainwater can be subjected to circular permeation, filtration, absorptive storage and sedimentation, waterlogging is prevented, and underground water is supplemented and extracted.

Description

Technical field [0001] The present invention relates to the technical field of sponge cities, in particular to an integrated system of circulating infiltration water storage sponge. Background technique [0002] Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and coping with natural disasters caused by rainwater. It can also be called "water elastic city". The international common term is "low-impact development rainwater system construction". When it rains, water is absorbed, stored, seeped and purified, and the stored water is "released" and used when needed. In the construction of sponge cities, gravel sponges and water storage module sponges are mostly used. Among them, gravel sponges have good load-bearing and water purification effects, but have the disadvantages of poor water storage and easy clogging; while water storage module sponges The body has good water stor...

Problems solved by technology

In the current construction of sponge cities, crushed stone sponges and water storage module sponges are mostly used. Among them, the crushed stone sponge has good load-bearing and water purification effects, but has the disadvantages of poor water storage and easy silting; while the water storage module sponge The water storage capacity of the body is good, but it has the disadvantages of load bearing, poor water purification effect and expensive price
