A drainage sidewalk capable of stagnant water purification

Abstract

The invention discloses a drainage sidewalk capable of stagnant water purification, which comprises a sidewalk surface and a stagnant drainage system, the stagnant drainage system is arranged on the side of the sidewalk surface; the stagnant drainage system includes a cover plate, a rock wool board, a permeable concrete layer, crushed Stone layer, permeable hose and mortar rubble side ditch; the permeable concrete layer is connected with the cover plate and gravel layer respectively, the permeable concrete layer provides a certain support for the cover plate, and one side of the permeable concrete layer is set with mortar rubble side ditch, It is used to collect and discharge rainwater. Rock wool boards are installed in the space enclosed by the cover plate and sidewalk surface on the other side, and permeable hoses are installed in the gravel layer. Rainwater is collected into the permeable hose through the gravel layer. The present invention builds a temporary stagnant water space inside the pavement, and arranges a stagnant drainage system at the bottom of the large-thickness base. While ensuring good water permeability of the pavement, a part of the rainwater is temporarily stagnated inside the pavement, effectively delaying the peak drainage time. Significantly reduces the pressure on the drainage system.

Description

technical field [0001] The invention belongs to the field of urban roads, in particular to a drainage sidewalk capable of stagnant water purification. Background technique [0002] In traditional urban construction, urban roads are all paved with impermeable water. When it rains, the rainwater is collected by the road surface and directly enters the drainage system. When the drainage system is too late to discharge, the water on the road surface will appear, which will lead to urban waterlogging. Drainage pavement refers to the pavement paved with permeable asphalt, permeable concrete and other materials. Rainwater can quickly infiltrate through the pavement gap, avoiding the generation of water on the road surface. [0003] Since the concept of sponge city design was put forward, cities in my country have begun to vigorously promote the construction of drainage pavement. The permeable asphalt and permeable concrete materials used in the drainage pavement have well-develop...

AI Technical Summary

Problems solved by technology

However, the above-mentioned development facilities need to occupy a large amount of urban space, and the construction cost is also high. They can only be used in parks, leisure squares, etc., and cannot well reduce the pressure on the urban drainage system.

The existing drainage pavement design, the stagnant water space and peak delay effect formed by the drainage structure layer are limited, and the ideal regulation, storage and purification effects cannot be achieved.
