Ground permeating rainwater recovery system utilizing building waste materials and construction method of ground permeating rainwater recovery system

Abstract

The invention discloses a ground permeating rainwater recovery system utilizing building waste materials. The ground permeating rainwater recovery system comprises a soil foundation, a permeating layer, a base layer, a planting soil layer and a face layer which are sequentially arranged from bottom to top. The permeating layer is a building waste material rough particle layer which is evenly distributed with the particle size of 30-50 mm, a permeating pipe is laid in the building waste material rough particle layer and permeating pipe is connected with a water collecting well through a connecting pipe. The base layer is a building waste material fine particle layer which is evenly distributed with the particle size of 1-10 mm. The face layer is lawn blocks and waste engineering stones, and the lawn blocks and the waste engineering stones are arranged alternately. The invention further discloses a construction method of the ground permeating rainwater recovery system utilizing building waste materials, and the method includes the steps of site flatting, soil foundation processing, building waste material crashing, permeating layer laying and the like. According to the ground permeating rainwater recovery system utilizing building waste materials and the construction method of the ground permeating rainwater recovery system, building waste is reasonably used, building resources are saved, the environment is protected, rainwater is recycled, and water resources are saved.

Description

Technical field [0001] The invention relates to a ground permeable rainwater recovery system using waste building materials and a construction method thereof, belonging to the technical field of ecological environment construction and resource protection. Background technique [0002] At present, the amount of urban construction waste in my country has accounted for 30% to 40% of the total amount of urban waste. With the acceleration of urbanization, a large number of construction projects will increase the total amount of construction waste. How to discharge and dispose of urban construction waste has become an important issue facing construction companies and environmental protection departments. [0003] Construction waste is generally generated during the construction process or the repair and demolition of old buildings, including soil, stones, concrete blocks, broken bricks, waste wood, scrap metal, waste pipes and electrical waste, among which there is no pollution Directly...

AI Technical Summary

Problems solved by technology

[0004] At present, there are two ways to dispose of construction waste in my country: one is that most of the construction waste is directly transported to the suburbs or villages for open-air landfill without any treatment, which not only consumes a lot of land, but also requires landfill. Occupation fees and garbage removal fees, etc. At the same time, the removal and stacking process will pollute the environment

The second is to transport the construction waste to the "recycling treatment center" for reuse after pretreatment, but building a treatment plant requires a lot of construction costs, operation and management costs, and consumes energy
