Shade tree pool with water storage and drainage device

Abstract

The invention relates to the field of municipal greening management and maintenance, and provides a shade tree pool with a water storage and drainage device. The shade tree pool comprises a collection and drainage device arranged under a sidewalk, the storage and drainage device arranged under a portion between a green belt and a roadway and a shade tree pool body arranged under the green belt; the collection and drainage device is used for moderately collecting leaking rainwater and conveying the collected rainwater to the shade tree pool body; the storage and drainage device is used for moderately filtering sewage to generate filter water, conveying the filter water to the shade tree pool body, and draining excessive sewage to a municipal road sewage pipe; the shade tree pool body is used for planting shade trees, receiving and moderately storing the rainwater conveyed by the collection and drainage device and the filter water conveyed by the storage and drainage device, continuously conveying the rainwater and filter water into a planting soil layer through water absorbing cotton ropes, and releasing the excessive rainwater and filter water to a municipal road rainwater pipe; the shade tree pool body is also used for receiving and storing irrigation water, and continuously conveying the irrigation water into the planting soil layer through the water absorbing cotton ropes.

Description

technical field [0001] This technology relates to the field of municipal greening management and maintenance, and provides a street tree pond for municipal roads, especially a street tree pond with a storage and drainage device, which can collect and store rainwater infiltrated from the surface in an appropriate amount and discharge excess rainwater To the rainwater pipes of municipal roads, it can also filter sewage in an appropriate amount and store filtered water, and discharge excess filtered water to municipal road rainwater pipes. The stored rainwater and filtered water can continuously supply the growth of street trees. It is an ecological water-saving type with storage and drainage functions. urban street tree tree pool. Background technique [0002] The tree pool structure used for planting green trees on municipal roads is more widely used to add some simple coverings on the basis of bare soil, such as iron grates, resin grids, cobblestones, ceramsite, grass planti...

AI Technical Summary

Problems solved by technology

[0006] However, at present, the street trees and tree pools in the city still cannot effectively participate in the urban drainage and improve the urban drainage efficiency. Moreover, there will be pollutants such as grease and chemicals deposited on the urban roadways. These pollutants can seep into the ground through surface runoff with rainwater , pollute the urban groundwater environment, and also affect the healthy growth of street trees
