Garden distributed rainwater collection and ecological provision protection system

Abstract

The invention discloses a garden distributed rainwater collection and ecological provision protection system. The system is composed of an ground tree protection part, a penetrating part and an underground rainwater collection and recovery well. Rainwater flows into the penetrating part through a large permeable cover plate, a small permeable cover plate, an outer permeable support frame and an inner permeable support frame and enters soil; when water pressure in the soil is greater than water pressure in the well, water in the soil passes through geotextile and then permeates into the rainwater collection and recovery well; when the water pressure in the well is greater than the water pressure in the soil, the water in the well permeates into the soil through the geotextile so as to supplement underground water and change the moisture content of the soil, and quick entering and slow going are realized through internal and external pressure or concentration difference. According to the garden distributed rainwater collection and ecological provision protection system, industrial waste steel slag is used as surrounding protection devices of shade trees, so that the water can permeate and can be purified, the trees can be protected, urban rain and flood resources are used locally, the discharge pressure of urban pipelines is reduced, and the utilization rate of the rain and flood resources is increased.

Description

technical field

[0001] The present invention relates to utilizing the planting characteristics of gardens and shade trees dotted around the city to collect rainwater, reuse and replenish groundwater, more specifically, it involves using discarded steel slag with water permeability as raw materials to make a shade tree The utility model relates to an ecological supply protection device, which belongs to the field of ecological environmental protection. Background technique

[0002] Existing shade tree protection device mainly uses natural stone, organic macromolecule material as raw material, makes enclosure protection around the shade tree. Using this method will inevitably destroy mountains and consume energy, which is contrary to the "low-carbon, green, and circular" development concept we follow. Stone is a hard material, which completely blocks the above ground and underground, and cannot realize the sponge city construction function of "natural penetration". Although ...
