Urban rainwater pipeline system capable of effectively supplementing underground water

Abstract

The invention discloses an urban rainwater pipeline system capable of effectively supplementing underground water. The urban rainwater pipeline system includes a plurality of rainwater openings, filtering screens, rainwater connecting pipes and manholes which are quantitatively corresponding to the rainwater openings respectively, municipal rainwater pipes and filtering layers; each rainwater opening is provided with a first channel which is communicated with two ends of the rainwater opening; and each rainwater connecting pipe is provided with a second channel which is communicated with two ends of the rainwater connecting pipe; each municipal rainwater is provided with a third channel which is communicated with two ends of the municipal rainwater; the manholes are provided with cavities; the rainwater openings are connected with the rainwater connecting pipes; the first channels and the second channels are connected together so as to form channels which are communicated with the rainwater openings and the rainwater connecting pipes; the rainwater connecting pipes are connected with the manholes; the second channels are communicated with the cavities of the manholes; the manholes are connected with the municipal rainwater pipes; the cavities of the manholes are communicated with the third channels of the municipal rainwater pipes; the municipal rainwater pipes are provided with water seepage holes which are communicated with the interiors and the exteriors of the pipe walls of the municipal rainwater pipes; the exteriors of the municipal rainwater pipes are provided with the filtering layers; the filtering layers completely cover the water seepage holes; and the filtering screens are arranged at end portions of the rainwater connecting pipes, wherein the end portions of the rainwater connecting pipes are adjacent to the rainwater openings.

Description

technical field [0001] The invention relates to the field of drainage and the technical field of hydrogeology, in particular to an urban rainwater pipeline system for effectively compensating groundwater. Background technique [0002] With the acceleration of the urbanization process, the rate of ground hardening continues to increase, the urban population surges, the water consumption continues to increase, and environmental pollution has aggravated the water quality-type water shortage crisis. In order to meet the needs of urban water resources, people continue to increase the exploitation of groundwater resources, resulting in serious overexploitation, a sharp decrease in urban underground water storage, a continuous decline in groundwater levels, and a corresponding increase in the area of ​​underground funnels. At the same time, the high rate of ground hardening increases the runoff of rainwater, and insufficient infiltration makes it impossible to replenish groundwater...

AI Technical Summary

Problems solved by technology

This technology achieves the purpose of reseeping urban rainwater to compensate groundwater, but the initial rainwater pollution is serious, and the device may pollute groundwater by reseeping initial rainwater into the ground

In addition, the connecting pipe and reinjection well in this device need to be laid separately, the underground structure is complicated, and the implementation cost is relatively high
