Description

TECHNICAL FIELD

With the acceleration of urbanization, the degree of urban ground hardening is continuously improved, the rainwater infiltration path is blocked, the urban waterlogging risk is significantly increased, and the traditional drainage system mainly aims to quickly remove rainwater, which directly discharges a large amount of rainwater into rivers, lakes and seas. This not only wastes valuable water resources, but also increases the burden of urban drainage network, and it is difficult to cope with increasingly frequent extreme rainfall events. At the same time, with the deepening of the concept of sustainable development of city and the increasing attention to water resource protection, there is an urgent need to develop a new type of infiltration overflow well with better performance, convenient cleaning and maintenance, and higher rainwater utilization efficiency.

Infiltration overflow well is mainly used to collect rainwater in roads and green areas. Rainwater enters the well body through the well mouth, is preliminarily treated by the pollution basket filter device to remove leaves, sand and garbage pollutants carried in the rainwater, and then part of the rainwater slowly infiltrates into the ground through the infiltration structure around the well body to supplement the groundwater. When the rainfall is large and the water level in the well rises above the set threshold, the excess rainwater is discharged into the water body near the urban drainage pipe network through the overflow pipeline to avoid excessive water accumulation in the well and cause waterlogging in the surrounding area. From the perspective of rainwater resource utilization efficiency, the existing infiltration overflow well also needs to be improved. In terms of rainwater collection and storage function, some infiltration overflow wells are designed unreasonably, which cannot fully collect and store rainwater, resulting in a large amount of rainwater being wasted. The well body has too small volume, and when the rainfall is large, rainwater will quickly be discharged through the overflow port, which cannot realize effective storage and subsequent utilization of rainwater.
