Water storage permeation device based on pervious concrete

Abstract

A water storage permeation device based on pervious concrete comprises a pervious material layer on the surface layer, a plurality of pervious bodies are arranged below the pervious material layer on the surface layer, each pervious body is provided with a shell, a rainwater collection cavity is formed in each shell, and a water inlet connected with the surface layer is formed in the upper portion of the shell; the shell is made of pervious concrete and has the functions of water storage and slow permeation. A cavity water storage principle is adopted, a water storage function and a permeation function are combined, and the device has the advantages that firstly, the device is used in cooperation with a permeable device on the market, rainwater can be stored in a cavity and slowly discharged to soil, and meanwhile, the problem that a permeable material is frozen and thawed to be damaged can be solved; secondly, compared with a large rainwater collecting system, the water storage permeation device is simple and convenient in structure, can be installed after a city is built, and is convenient to install and recycle and low in cost; and thirdly, the comprehensive performance is excellent, the permeability of a sponge city can be improved, the soil bearing capacity is improved by utilizing rainwater, reducing the saline-alkaline property of soil and consolidating and draining water, and high economic benefits are achieved.

Description

technical field [0001] The invention relates to a drought prevention technology, in particular to a water storage and infiltration device based on permeable concrete. Background technique [0002] The north is dry, and the South-to-North Water Diversion Project is costly. The city suffers from severe water shortage, and excessive exploitation of groundwater leads to land subsidence, seawater intrusion, and serious soil salinization. However, the arid cities in the north are severely waterlogged, which is in contradiction with the water-scarce environment. The reason is that the soil has poor water permeability, rainwater cannot penetrate into the ground, the soil is salinized, and vegetation is difficult to survive; Sponge city, laying permeable materials, but with little effect. Domestic urban construction focuses on ground construction, ignoring underground facilities, and a complete rainwater collection system was not built at the beginning of urban construction. At pr...

AI Technical Summary

Problems solved by technology

At present, the construction of the sponge city only studies the pavement materials on the surface, and there is no research and development of underground water storage and infiltration devices. Rainwater can enter the permeable materials, but it is difficult to enter the soil.

Moreover, in the north, these permeable materials cannot be discharged into the soil in time due to rain, which is easy to cause freeze-thaw damage
