Supporting Vegetation Buffers for Sponge City

Abstract

The invention provides a supporting vegetation buffer zone for the sponge city, which includes a ground body, a debris removal groove and a spiral relief; the bottom of the ground body is laid with a gravel cushion; energy body, and the whole ground body is laid with a downward slope to the right; the upper surface of the ground body at the lower right of the energy dissipation body is provided with a row of interconnected shunt energy reduction bodies; the lower right side of the ground body is provided with an inverted Trapezoidal purification channel, and the top opening of the purification channel is laid with an upper shield. The present invention cooperates with the above-mentioned various structures to comprehensively realize a supporting vegetation buffer belt structure for the sponge city, and through the setting of the energy-dissipating water bag, the debris removal tank, and the purification channel in the above-mentioned structure, the purpose of filtering runoff can be achieved , and can protect river banks and lake banks, effectively control floods, and vegetation planting trays and diversion energy-reducing bodies can absorb nutrients in runoff water, providing food and habitat for wild animals.

Description

technical field [0001] The invention belongs to the technical field of buffer strips for sponge cities, and more specifically relates to supporting vegetation buffer strips for sponge cities. Background technique [0002] The vegetation buffer zone is a vegetation area with a gentle slope, which slows down the surface runoff velocity through vegetation interception and soil infiltration, and removes part of the pollutants in the runoff. The vegetation buffer zone is used around roads and other impermeable surfaces, such as patent application CN201720783445 A vegetation buffer zone structure supporting a sponge city in .0, including vine vegetation and arbor vegetation; the buffer zone structure on the ground is a ladder-like structure, and a layer of sand and gravel is laid on the top surface of each layer, and the sand Grass plants are planted between the stone layer and the ground; a layer of stone protection at the end of the step is built on the top of the step section, ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a supporting vegetation buffer zone for the sponge city to solve the problem that the existing crushed stone energy dissipation pits are easy to accumulate sediments, are difficult to remove, and are easy to breed microorganisms and various bacteria for a long time. When it is used, it is often directly discharged, causing damage to the river bed
