System for preventing water from being accumulated on road surface and recovering and recycling urban rainfall and flood resources

Abstract

The invention relates to the fields of collecting and recycling of urban rainfall and flood resources and paving of a road surface, and provides a new method for recovering and recycling the urban rainfall and flood resources. According to the new method disclosed by the invention, the problem of accumulated water in roads of residential areas during torrential rains can be solved, and the rainfall and flood resources in the residential areas can be effectively recovered; through natural purification treatment, the rainfall and flood resources can be converted into high-level rainwater potential energy so as to be used for flushing floors or other relevant use. The technical scheme adopted by the new method disclosed by the invention lies in that a system for preventing water from being accumulated on a road surface and recovering and recycling urban rainfall and flood resources consists of a permeable plate, a diversion layer and water storage tanks, wherein the diversion layer adopts a structure that a bottom layer is paved, a top layer is designed into a ridge shape, and lateral diversion trenches formed at equal intervals are formed in the top layer road surface and are used for guiding rainwater to the water storage tanks; water outlets for flushing the road surface are mainly paved in an interval zone between every two adjacent diversion trenches; and the water storage tanks are hung to two sides of the diversion layer. The new method and the system disclosed by the invention are mainly applied to the field of paving of city road surfaces.

Description

technical field [0001] The invention relates to the fields of collection, recycling and pavement of rainwater resources in urban areas, as well as a technique and a design method for using rainwater potential energy of high-rise buildings to scour road surfaces. Specifically, it relates to a method for preventing road surface water and urban rainstorm and flood resource recovery and recycling. Background technique [0002] Rainwater resources refer to the rainwater that exceeds the natural digestion capacity of the surface after the precipitation in the atmosphere falls to the ground. In recent years, with the continuous acceleration of urbanization, the impermeable area covered by the ground has gradually replaced the well-permeable forest land and farmland, which has affected the natural water process. The daily life and traffic bring inconvenience, and the rainwater resources on the road surface are simply discharged into the river as "waste water", which causes waste to...

In recent years, with the continuous acceleration of urbanization, the impermeable area covered by the ground has gradually replaced the well-permeable forest land and farmland, which has affected the natural water process. The daily life and traffic bring inconvenience, and the rainwater resources on the road surface are simply discharged into the river as "waste water", which causes waste to a certain extent.
