Horizontal storage tank for sponge city rainwater collection system and construction method thereof

Abstract

The invention discloses a horizontal storage tank for a sponge city rainwater collection system and a construction method thereof. The horizontal storage tank comprises a water storage tank, a control well, an overflow well and a cyclone filter, the water storage tank is in an inverse I shape, the overflow well is connected with the water storage tank through an overflow tube, the side face of the over flow well is connected with the cyclone filter through a connecting tube, the cyclone filter is connected with the water storage tank through a filter connecting tube, the control well is connected with the water storage tank through a return tube, and the return tube is located at the bottom of the overflow tube. The construction method comprises the steps that foundation trench excavation, water storage tank manufacturing, rainwater collection system mounting and rainwater collection system debugging. The construction method is simple in steps and strong in proactivity, not only can rainwater collection and utilization of urban areas with various rainwater quantity be satisfied, but also the stability and reliability of integral rainwater collection system are effectively improved, the installation is convenient and fast, the maintenance is simple, the operation difficulty is reduced, and the economic benefits are high.

Description

technical field [0001] The invention relates to a horizontal storage tank for a sponge city rainwater collection system and a construction method thereof. Background technique [0002] In recent years, the problem of urban rainwater flooding has become increasingly serious. On the one hand, this phenomenon of long-lasting rainwater is caused by the imperfection of urban flood control facilities. Most urban flood control uses hard methods such as pipes and ditches to discharge floods. This requires the municipal pipe network to have strong flood control and drainage capabilities. Insufficient flood discharge capacity will easily cause rainwater to overflow if there is no place to discharge, resulting in urban rainwater flooding; on the other hand, the emergence of a large number of hard pavements in the city has isolated the groundwater supply from surface precipitation, making the land lose its water permeability function , resulting in the inability of rainwater to infiltr...

AI Technical Summary

Problems solved by technology

[0004] Rainwater collection systems in the prior art generally use water tanks or large puddles. Although they can temporarily collect rainwater, the rainwater handling effect in different seasons is poor, the adjustment ability is low, and it is easy to cause overflow. High cost, easy to pollute the environment
