Sponge urban road system and rainwater collection and utilization method

Abstract

The invention discloses a sponge urban road system. The sponge urban road system includes a sunken green belt, a punching station stone, a sand basin, an overflow well, a water storage tank, a photovoltaic module, and a water suction pump; the sunken green belt is arranged between a motor lane and a bicycle lane and is concave; the punching station stone is positioned near the motor lane and is on the same line with a station stone of the motor lane; the sand basin is positioned between the punching station stone and the sunken green belt; the overflow well is positioned on the lowest position of the sunken green belt; the upper part of the overflow well communicates with a drainage pipe of a municipal pipe through an overflow pipe; the water storage tank is positioned near the overflow well and is separated by a filtering wall; and the photovoltaic module is connected to a power source control module through a wire, the power source control module is connected to the water suction pump, and the water suction pump pumps water in the water storage tank into a water distribution pipe. The invention further provides a rainwater collection and utilization method by using the sponge urban road system. The sponge urban road system and the rainwater collection and utilization method can absorb and store rainwater on the lanes and can utilize the stored water.

Description

technical field [0001] The invention relates to the technical field of rainwater resource utilization and water supply and drainage, in particular to a sponge city road system and a method for collecting and utilizing rainwater. Background technique [0002] Sponge city, also known as "water elastic city", means that the city can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. Water, the function of "releasing" stored water and utilizing it when needed. [0003] During the construction process of the sponge city renovation project, due to the influence of the environment and surrounding buildings, the construction cannot be carried out in full accordance with the concept of the sponge city. In road reconstruction, the sunken green belt is generally reconstructed, or the overflow outlet and sedimentation tank in the green belt are added, or the permeable pavement surface is replaced on the sidewalk, and the...

AI Technical Summary

Problems solved by technology

When there is heavy rainfall, most of the rainwater will be discharged to the municipal pipe network through the overflow outlet, which cannot effectively "retain" the water and cannot be reused
