Sponge underground water storage body and application thereof

Abstract

The invention discloses a sponge underground water storage body. The sponge underground water storage body comprises an enclosure part and a closed cavity defined by the enclosure part. The enclosure part is prepared from sponge pervious concrete. The sponge pervious concrete is prepared from park waste, cement and sand. The park waste is from branches or leaves or bark or wood chips or sawdust or straw or rice hulls or hard fruit shells. The invention further provides a method for applying the sponge underground water storage body. The method includes the step of arranging the sponge underground water storage body below the ground surface and above the water level of underground water. The whole sponge underground water storage body is made of a previous material, water can permeate into the cavity through the top of the water storage body in rainstorm weather and then slowly permeates into external space through the bottom of the water storage body, and waterlogging can be relieved.

Description

technical field [0001] The invention relates to the construction field, in particular to a spongy underground water storage body and its application. Background technique [0002] With the continuous prosperity and development of the world economy, the earth has gradually changed its original appearance. Urban construction is changing with each passing day and developing rapidly. The construction of public buildings, houses, and roads hardens the surface environment, which almost completely changes the ecological environment of the construction site. The atmospheric evaporation cycle is affected, resulting in lower air humidity and higher temperature in the urban area, forming a "heat island" effect". This "heat island effect" makes the city hotter and hotter in summer, and the dust in the atmosphere increases, making people's life more and more uncomfortable, threatening human health, and the hardening of the ground makes it almost impossible for rainwater to replenish gro...

AI Technical Summary

Problems solved by technology

[0003] 1. Sewage is directly discharged into urban rivers and lakes, causing a large amount of clean surface water to become sewage and lose its use value;

[0004] 2. The natural environment of urban surface water has been destroyed, the area of ​​wetlands has decreased, rivers have hardened, etc., resulting in changes in water ecology, and water loses its self-purification function;

[0006] 4. Excessive exploitation of groundwater by industry and residential groups leads to a drop in groundwater levels and ground subsidence,
