Rainwater permeation system based on ecological parking lot and preparation method

Abstract

The invention discloses a rainwater permeation system based on an ecological parking lot, which comprises a first anti-settling water-permeable cloth layer, a plain soil base layer, a porous asphalt water-permeable layer, a second anti-settling water-permeable cloth layer, a pumice water-permeable bottom base layer, a sand-free macroporous concrete base layer, a water permeation layer, a medium sand leveling layer and an 8-shaped water-permeable grass planting brick layer which are sequentially arranged from bottom to top. Filtering and dredging pipes are arranged on the 8-shaped water-permeable grass-planting brick layer at intervals, a filtering surface layer is arranged at an opening in the top of each filtering and dredging pipe, and the filtering and dredging pipes sequentially penetrate through the 8-shaped water-permeable grass-planting brick layer and the medium sand leveling layer from top to bottom and then communicate with the interior of the water seepage layer. According to the rainwater permeation system based on the ecological parking lot and the preparation method, loss of sandy soil can be effectively prevented through the two anti-sinking permeable cloth layers, roadbed sinking is avoided, the plant growth environment of the ecological parking lot is improved, the plant water supplementing frequency is reduced, and the system is good in breathability, water permeability, adhesion and water retention and high in supporting strength; and the method is green and environment-friendly and can improve the local thermal environment.

Description

technical field [0001] The invention belongs to the technical field of rainwater infiltration systems, in particular to a rainwater infiltration system based on an ecological parking lot and a preparation method thereof. Background technique [0002] With the rapid development of economy and society and the improvement of people's living standards, the number of cars in my country is also increasing year by year, and open-air or underground parking lots have developed rapidly. However, the conventional cement or asphalt parking lots have a simple structure and isolate The exchange of water and heat between the earth and the atmosphere can easily form the urban heat island effect, which can easily generate high temperatures and cause human discomfort. In addition, open-air parking lots often accumulate water, especially in heavy rain seasons. Although there are green plants, However, the water absorption effect is very little, the bearing capacity is small, and the accumulation...

[0002] With the rapid development of economy and society and the improvement of people's living standards, the number of cars in my country is also increasing year by year, and open-air or underground parking lots have developed rapidly. However, the structure of conventional cement or asphalt parking lots is simple and isolated The exchange of moisture and heat between the earth and the atmosphere can easily form the urban heat island effect, which can easily generate high temperature and cause human discomfort. In addition, open-air parking lots often accumulate water, especially in heavy rain seasons. Although there are green plants, However, the water absorption effect is very small, the bearing capacity is small, and the accumulation of rainwater will also soften the pavement foundation, resulting in damage to the foundation and affecting normal use
