A sponge double waste permeable concrete pavement

Abstract

The invention discloses a novel sponge body double-waste pervious concrete pavement. The pavement comprises the following layers in order: a surface layer, a connecting layer, a base and a cushion. The connecting layer is sponge body garden waste mortar; the base is novel sponge body double-waste pervious concrete; the sponge body garden waste mortar comprises cement, sand and garden waste; the novel sponge body double-waste pervious concrete comprises cement, sand, garden waste, regenerated stones and a brightener. The sponge body double-waste pervious concrete pavement solves the city garden waste pollution problem, changes waste into valuables, and is good for environmental protection; the pavement has the advantages of water imbibition, water penetration, water storage, permeability and higher strength; the garden waste can be collected conveniently, and concrete, mortar and other materials are saved, so that the pavement is economical.

Description

technical field [0001] The invention relates to a pavement, in particular to a novel spongy double-waste permeable concrete pavement. 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 groundwater, and th...

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, threatening urban buildings;

[0007] 5. The hardening of the road surface prevents rainwater from penetrating into the ground, and the accumulation of water on the ground affects urban sanitation and traffic, or after a heavy rain, the amount of water flowing into the sewer increases greatly, which adds a huge processing burden to urban drainage pipes and sewage treatment plants

Due to the large porosity, the water permeability of the pavement is improved, but the process of preparing large pores is more complicated, and the higher the porosity, the worse the compression resistance, and the protection of the ecological environment is also very limited.
