Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] This structure combines the advantages of collecting and utilizing hardened ground rainwater and infiltrating underground, and realizes the comprehensive utilization of road rainwater based on the principle of convenient construction. The comprehensive utilization system of hardened ground rainwater uses the existing water collection wells to collect ground rainwater, and through the runoff rainwater-storage sedimentation tank-storage tank system, part of the rainwater penetrates into the roots of plants and the surrounding soil through permeable hoses to infiltrate trees. Excess rainwater is infiltrated on-site to replenish groundwater; part of the rainwater is purified and recovered by artificial soil infiltration through the storage tank and can be directly used for environmental water. Since the surface runoff contains a lot of sedim...

Abstract

The invention discloses a ground rainwater comprehensive utilization structure. The ground rainwater comprehensive utilization structure comprises a settling pond and a water storage pond which are arranged below a road surface, a water grate is arranged on the settling pond and flush with the road surface, one side of the pond wall of the settling pond is provided with a drainage pipe and a water outlet, the drainage pipe is communicated with a municipal pipeline, an automatic overturn gate is arranged at the junction between the drainage pipe and the pond wall of the settling pond, the water outlet of the pond wall of the settling pond is communicated with the water storage pond, the water outlet is lower than that axis of the automatic overturn gate, a filter screen is hung on the water outlet, and water-pervious hoses are arranged on the pond wall of the water storage pond and stretch to roots of plants on the road surface. The ground rainwater comprehensive utilization structure integrates direct utilization and indirect utilization of rainwater on the hardened ground, runoffs on the road are collected to serve as supplement water sources of green belts on the roadside according to the water usage characteristic of street trees and the green belts on the road, a pipeline is shortened, and the rainwater can further serve as water for environment after being processed through percolation.

Description

technical field [0001] The invention relates to a comprehensive utilization structure of ground rainwater. Background technique [0002] With the aggravation of the shortage of water resources in our country, many cities have carried out research on rainwater utilization. In the past, urban water resources were mainly devoted to the development of surface water resources and groundwater resources. They did not pay attention to the utilization of urban runoff rainwater and let it discharge, resulting in the loss of a large amount of precious rainwater resources. With the rapid expansion of cities, the amount of rainwater loss also increased. getting bigger. And a large amount of rainwater discharge has increased the burden on urban drainage facilities. Untreated urban ground (roads, squares, etc.) rainwater runoff is also one of the main non-point source pollution. Road rainwater has brought about a series of problems such as the deterioration of the urban ecological environ...
