A road rainwater harvesting system that helps improve the heat island effect in residential areas

Abstract

The invention relates to a road rainwater collection system that helps to improve the heat island effect in residential areas. It is provided with a permeable floor. The permeable floor is mainly laid by a permeable plate. The bottom of the see-through plate is supported by a column. Below is the bottom foundation. The space between the permeable plate and the bottom foundation is a water collection space. A submersible pump and an upper limit water level gauge for drainage can be arranged in the water collection space. The output pipe of the submersible pump is connected to the storage A pool, the reservoir is provided with vertical baffles and horizontal baffles, and is equipped with a water purification submersible pump and a mortar pump. The permeable plate preferably adopts a double-layer structure, and the upper layer is a sand-based permeable layer. The lower layer is a stone-based water-permeable layer, and a hard frame is arranged around the stone-based water-permeable layer to surround the side surface of the stone-based water-permeable layer. The invention can improve the ability of the pavement to absorb and collect rainwater runoff, and help slow down the heat island effect.

Description

technical field [0001] The invention relates to a road rainwater collection system that helps to improve the heat island effect in residential areas, and is suitable for collecting rainwater on the ground and road surfaces of living quarters, entertainment and leisure activities and other similar occasions. Background technique [0002] The heat island effect refers to the phenomenon that the temperature in an area is higher than that of the surrounding areas. Due to the large amount of artificial heating in the city, and the high heat storage bodies such as buildings and roads and the reduction of green spaces, the city "heats up" and makes the city The temperature in some areas is significantly higher than that in the peripheral areas. Usually, on the near-surface temperature map, the temperature in the suburbs has little change, while the urban area is a high-temperature area, like an island protruding from the sea. For example, there are a large number of artificial stru...

[0005] However, in many occasions in the realization, for example, the foundation of the pavement of the living quarters (including the ground of the outdoor activity place) is mostly a hardened foundation, or mixed with a large amount of construction dregs, etc., and the water permeability is very poor. Basically, the water permeating under the bricks is difficult to continue to infiltrate downwards, and the purpose of allowing rainwater to enter the ground cannot be achieved. The water storage capacity of the surface is poor, which significantly reduces the evaporation and heat dissipation capacity and strengthens the heat island effect.
