Description

A device for collecting precipitation for soil water recharge under surface hard cover

technical field

The utility model relates to the field of environmental science, in particular to a device for collecting precipitation for soil water replenishment under hard surface covering.

Background technique

Hard covering refers to the phenomenon that the surface of non-building land is covered with hard materials (such as floor tiles, concrete and asphalt, etc.). This phenomenon is common in cities, and its existence will bring many non-polluting environmental and ecological problems:

1. Hard coverage will change the thermal properties of the underlying surface of the city, causing the heat island effect;

2. Hard covering will cause poor ventilation, and it will be difficult for precipitation to penetrate into the ground, and groundwater cannot be replenished;

3. Hard covering will seriously affect the soil environment, making plant growth vulnerable to insect damage, freezing damage, drought and other problems;

4. The continuous expansion of hard coverage will also lead to the loss of water resources and the destruction of the balance of the water circulation system.

At present, rainwater, as a natural resource, plays an important role in regulating and replenishing urban water resources and improving urban natural ecosystems. The way of rainwater collection and replenishment to soil is mainly through ground rainwater collection, which can be divided into hard cover runoff rainwater collection and surface rainwater infiltration. Among them, hard cover rainwater runoff collection mainly uses the runoff generated on hard cover surfaces such as urban roads, squares, and parking lots after rainfall to flow into the ground storage tanks built to recycle rainwater and collect water for urban cleaning, irrigation and Landscape water, etc. The surface rainwater infiltrates underground mainly through permeable ponds, infiltration trenches, infiltration tanks and urban green spaces, flower beds and gardens to increase the underground infiltration of rainwater. When constructing green spaces, flower beds, and gardens, a concave design is usually used to investigate the relationship between the elevation of the surrounding green areas, the elevation of the green areas, and the elevation of the storage pool, so that the surrounding elevations are higher than the elevation of the green areas, and the rainwater outlets are set on the green areas to collect and store water. The elevation of the pond is between the elevation of the greenbelt and the surrounding elevation, so that the rainwater runoff flows into the greenbelt to recharge the soil through infiltration, and the excess rainwater runoff enters the reservoir for irrigation of the greenbelt and urban cleaning. Another way is to use permeable ground such as permeable pavement bricks, grass-embedded pavement, turf bricks, loose grain filler, porous asphalt and porous concrete to replace traditional hard pavement, so that rainwater can directly infiltrate into the ground to replenish the soil.

To sum up, the rainwater collected by hard cover rainwater runoff will not be directly used to recharge groundwater and soil under hard cover, while surface rainwater generally occupies a large area in the underground infiltration and refill measures, and the topography and geographical location and other conditions have great influence on the project. There are many conditions and constraints, and there are certain difficulties in implementation. At the same time, there are also problems such as the disconnection between water storage and rainwater utilization, and low resource utilization. Therefore, how to use rainwater harvesting to improve the soil environment under urban hard cover and take effective and economical water replenishment measures are key issues to be solved urgently.

Therefore, the prior art still needs to be improved and developed.
