A new rainwater interception and seepage drainage integrated system

Abstract

An embodiment of the invention discloses a novel rainwater cut-off and permeation drainage integral system which comprises a permeation rainwater inlet, a permeation filter well, a permeation well, HDPE (high-density polyethylene) permeation pipes, a permeation pond, geotextile fabrics and gravel layers and is a set series product. The novel rainwater cut-off and permeation drainage integral system has the advantages that the novel rainwater cut-off and permeation drainage integral system is a set rainwater utilization system, rainwater can be initially purified and can be stored and permeated, redundant rainwater can be normally drained, and the system has proper rainfall load bearing capacity; the novel rainwater cut-off and permeation drainage system can replace the traditional rainwater pipelines, rainwater inlets and rainwater inspection wells and is provided with the permeation rainwater inlet, the rainwater pipes, the rainwater wells and the rainwater pond, so that the rainwater can be collected, permeated and drained; the traditional deeply buried rainwater pipelines can be reduced, and the outdoor pipe network laying difficulty can be lowered.

Description

technical field [0001] The invention relates to the field of rainwater interception and seepage drainage, in particular to a novel rainwater interception and seepage drainage integrated system. Background technique [0002] 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, infiltratio...

AI Technical Summary

Problems solved by technology

At present, there is no mature rainwater interception-infiltration-storage-discharge system. Generally, the rainwater is completely discharged or fully recovered or partially infiltrated.
