Rainwater containing deceleration strip used for slope road surface of city

Abstract

The invention relates to a road surface deceleration strip. The road surface deceleration strip comprises a shell, wherein the front end of the shell is hinged with a rotating shaft fixed at the upper end of the slope road surface, a spring is installed at the tail end of the shell and is sheathed on a limiting pile fixed at the lower end of the slope road surface, a water containing bag is arranged in the shell, the bottom of water containing bag is tightly attached on the road surface, the top of the water containing bag is tightly attached on the inner surface of the shell, a water inlet board is arranged at the front end of the water containing bag, a water inlet is formed in a water containing bag body behind the water inlet board, a water inlet membrane section is suspended at the top of the inner wall of the water inlet, water drain holes are respectively formed in the two sides of the tail part of the water containing bag, and are in butt joint with a water drain pipe, and a water outlet membrane section is suspended at the tops of the outer wall of the water drain holes. The road surface deceleration strip has the following advantages that running water on the road surface can be stored and held, the running water amount of the road surface is reduced, meanwhile, the running water on the road surface can be transferred to green belts on the two sides of a road, the plant process of the running water during the initial period can be implemented, and the surface source pollution load of the road surface can be reduced.

Description

technical field [0001] The invention relates to a road deceleration belt, in particular to a deceleration belt used for urban slope road surfaces. Background technique [0002] At present, although my country's urban point source pollution has gradually been effectively solved, my country is in the process of rapid urbanization, the population is increasing, the city is in a period of large-scale construction, land use types are undergoing huge changes, and a large number of impermeable surfaces appear. The impact of urban rainfall runoff pollution on the water environment is prominent, especially in mountainous cities. The terrain of mountainous cities has large undulations and steep slopes. During the rainfall process, they are easy to generate runoff and have strong scouring effects, which have a prominent impact on the water environment of the basin. Therefore, the control of urban non-point source pollution is of great significance to ensure the safety of urban water en...

AI Technical Summary

Problems solved by technology

The disadvantages of the existing speed bumps are: neither can store the runoff on the road surface, reduce the runoff on the road surface, nor can it transfer the runoff on the road surface to the green belts on both sides of the road, implement the plant treatment of the initial runoff, and reduce the amount of surface source pollution on the road surface
