Description

A new rainwater interception and seepage drainage integrated system

technical field

The invention relates to the field of rainwater interception and seepage drainage, in particular to a novel rainwater interception and seepage drainage integrated system. the

Background technique

The use of rainwater as a non-traditional resource has multiple functions: saving water to alleviate the water resource crisis; rainwater infiltration increases groundwater content and improves the regional ecological environment; reduces and slows down rainwater drainage and reduces urban rainwater floods, etc. If the rainwater that falls on the ground or the roof is discharged directly, the runoff of urban rainwater will be increased, and the drainage pressure of the municipal pipe network will be increased. The system integrating interception-infiltration-storage-discharge can play a role in initial filtration and purification of rainwater. The rainwater is stored and infiltrated through the infiltration rainwater outlet, infiltration pipe, infiltration well and infiltration tank, and the rainwater that is too late to infiltrate is discharged into the municipal pipe network. It can not only save water, relieve the pressure of municipal drainage, but also conserve groundwater and beautify the ecological environment. It is a way and means to make better use of rainwater. At present, there is no mature rainwater interception-infiltration-storage-discharge system, and generally only the means of complete discharge or complete recovery or partial infiltration are used for rainwater. the
