Multifunctional delayed drainage port suitable for rainwater infiltration drainage and bioretention facility

Abstract

The invention provides a multifunctional delayed drainage port suitable for a rainwater infiltration drainage and bioretention facility. The multifunctional delayed drainage port comprises a concrete foundation, an overflow well wall, a municipal water outlet and a top overflow channel and further comprises an infiltration drainage channel. The infiltration drainage channel comprises an infiltration drainage channel pipe arranged on the side wall of the overflow well wall, an inner side opening of the infiltration drainage is communicated with a well body through the overflow well wall, an outer side opening of the infiltration drainage is communicated with a rainwater facility, and the infiltration drainage channel and the top overflow channel are connected with a municipal pipeline through the well body and the municipal water outlet. The multifunctional delayed drainage port has the advantages that the multifunctional delayed drainage port is particularly suitable for rainwater facilities, like grass swales and rainwater gardens, needing infiltration drainage and has the functions of delayed adjustment and graded control according to different rainfall adjustment, rainwater retention of the rainwater facility is prolonged, infiltration drainage water can be collected and drained, long-time soaking of the plants is prevented, and normal growth of the plants is protected.

Description

technical field [0001] The invention relates to multi-stage time-delay discharge equipment, in particular to a multifunctional time-delay discharge port suitable for infiltration and drainage of rainwater biological retention facilities. Background technique [0002] Delayed discharge of rainwater is one of the common technologies in rainwater management. It is mainly used to adjust the amount of rainwater runoff entering the municipal pipe network and play a role in delaying the regulation of runoff. The traditional rainwater delayed discharge outlet is mainly used for regulating and storing water levels in rainwater facilities. It has the function of controlling the water flow, but it has the problem of single structure and single function, and it is difficult to meet the requirements of runoff classification control or storm peak flow control. Therefore, the existing technology needs to be further improved and perfected to realize multifunctional rainwater Further develop...
