Drainage sidewalk capable of purifying stagnant water

Abstract

The invention discloses a drainage sidewalk capable of purifying stagnant water, which comprises a sidewalk pavement and a stagnant water drainage system, and the stagnant water drainage system is arranged on the side face of the sidewalk pavement; the stagnant drainage system comprises a cover plate, a rock wool plate, a pervious concrete layer, a gravel layer, a pervious hose and a mortar rubble side ditch; the pervious concrete layer is connected with the cover plate and the gravel layer, the pervious concrete layer provides certain support for the cover plate, one side of the pervious concrete layer is provided with a mortar rubble side ditch used for collecting and discharging rainwater, the rock wool board is arranged in a space defined by the other side of the pervious concrete layer, the cover plate and the sidewalk pavement, the pervious hose is arranged in the gravel layer, and rainwater is collected into the permeable hose through the gravel layer. The temporary stagnant water space is constructed in the pavement, the stagnant water drainage system is arranged at the bottom of the large-thickness base layer, it is guaranteed that the pavement has good water permeability, meanwhile, part of rainwater is temporarily retained in the pavement, the time of the drainage peak value is effectively delayed, and the pressure of the drainage system is remarkably relieved.

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 paved with impervious pavements. When it rains, the rainwater collects through the road surface and directly enters the drainage system. When the drainage system is too late to discharge, there will be water accumulation on the road surface, which will cause urban waterlogging. Drainage pavement refers to the pavement paved with permeable asphalt, permeable concrete and other materials. Rainwater can quickly infiltrate through the gaps in the pavement, avoiding the generation of water accumulation on the road surface. [0003] Since the sponge city design concept was put forward, cities in my country have begun to vigorously promote the construction of drainage pavements. The permeable asphalt and permeable concrete materials used in the drainag...

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.
