A kind of urban micro underground reservoir and construction method

Abstract

The invention discloses an urban miniature underground reservoir. The underground reservoir is composed of multiple water storage ponds which are buried underground and connected with municipal administration rainwater drainage pipelines, and the miniature reservoir is located below urban road auxiliary roads and green belts. Rainwater on the roads and the peripheries of the roads can flow into the reservoir through drainage pipes, and when it rains, the rainwater can flow into the miniature reservoir through the drainage pipes to be stored; as tiny holes are formed within the range above the one fourth to one third portion of the side face of the reservoir, water in the miniature reservoir can slowly permeate into a foundation soil body to supplement underground water and improve the underground water environment. The invention further discloses a construction method for the miniature underground reservoir. The miniature underground reservoir can relieve pressure of the municipal administration rainwater drainage pipelines, improve the municipal water use capacity, supplement the underground water and improve the underground water environment, and therefore the miniature underground reservoir has large social benefits and high ecological value.

Description

technical field [0001] The invention belongs to the field of municipal engineering, in particular to an urban miniature underground reservoir connected with a rainwater drainage pipe and a construction method. Background technique [0002] With the increasing scale of urbanization, there are more and more hard surfaces such as concrete and asphalt, and the isolation between rainwater and groundwater is becoming more and more serious. Due to the expansion of cities, the diameter of urban drainage pipes is also increasing. When the rainstorm is too late to discharge, it will cause waterlogging, and when it is serious, it will endanger people's lives and material property safety. For example, in 2012, the torrential rain in Beijing on July 21 caused 79 deaths and 10,660 houses collapsed, 1.602 million people were affected, and the economic loss was 11.64 billion yuan. In May 2014, the heavy rain in Shenzhen caused about 150 local roads to accumulate water, 20 areas were floode...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the shortcomings of traditional rainwater drainage pipes, such as insufficient drainage capacity during heavy rains, lack of replenishment of groundwater, and waste of water resources, and propose an underground micro-reservoir, which can effectively relieve the pressure of drainage pipes and prevent urban floods. , and the groundwater is replenished, alleviating urban water shortage and drought
