Rainwater regulating and storing system of a sponge city ecological road

Abstract

The invention discloses a rainwater regulating and storing system of a sponge city ecological road, which comprises a pavement, a comprehensive pipe corridor, an infiltration system of a sidewalk greening isolation zone, a regulating and storing system of a non-motor vehicle lane isolation zone and a central isolation zone; the rainwater regulating and storing system comprises a pavement, a comprehensive pipe corridor, a pavement greening isolation zone infiltration system, a non-motor vehicle lane isolation zone regulation system and a central isolation zone regulation system. The pavement includes pedestrian pervious asphalt pavement, non-motor vehicle pervious concrete pavement and motor vehicle pervious concrete pavement. The comprehensive pipe corridor is buried under the pedestrian permeable asphalt pavement; the infiltration system of sidewalk greening isolation zone is located between pedestrian permeable asphalt pavement and non-motor vehicle permeable concrete pavement. The regulating and storing system of the non-motor vehicle lane isolation belt is located between the non-motor vehicle permeable concrete pavement and the motor vehicle permeable concrete pavement; the regulating and storing system of the non-motor vehicle lane isolation belt is located between the non-motor vehicle permeable concrete pavement and the motor vehicle permeable concrete pavement. The other side of the motor vehicle permeable concrete pavement is provided with a central isolation belt regulating and storing system. The invention can realize the rapid drainage of the main road of the city, effectively absorb the rainwater in the rainstorm weather, store and utilize the rainwater, realize the automatic sprinkling of the city greening, replenish the groundwater, alleviate the prominent problems such as the shortage of the water resources and the like.

Description

technical field [0001] The invention relates to a rainwater regulation and storage system, in particular to a sponge city ecological road rainwater regulation and storage system. Background technique [0002] With the development of the national economy and the continuous improvement of the level of awareness of ecological protection, the call for the design and construction of sponge cities is getting higher and higher, and the requirements for the collection and recycling of rainwater are constantly being put forward. In urban planning and construction, urban roads account for most of the urban area. Therefore, realizing the rainwater regulation and storage function of urban roads is of great significance to the realization of water storage, water transfer, and water purification in sponge cities. [0003] At this stage, the design of roads in large, medium and small cities in my country usually adopts the slope form of drainage from the middle to both sides. Drainage well...

AI Technical Summary

Problems solved by technology

This type of road design is insufficient for the instantaneous road surface drainage capacity. Therefore, when the rainstorm season comes, due to the small number of drainage outlets, insufficient diameter of infiltration pipes, and accumulation of garbage to block the drainage outlets, it is very easy for the city to look at the sea.

In addition, the green space of urban roads is insufficient, and the separation space between motor vehicle lanes, non-motor vehicle lanes and sidewalks is insufficient, and the pollution from motor vehicle lanes is easy to spread to the sidewalks on both sides.

At the same time, the current road design cannot realize the storage and transfer of rainwater. After the rainwater hits the ground, it flows into the drainage pipes and is directly discharged into the urban sewage system.

In the dry season, the plants on the green belt need to be sprayed manually, and urban tap water is used as water for irrigation. It is difficult to use the stored rainwater for automatic spraying, resulting in a waste of manpower and water resources.
