Pavement drainage system and construction method thereof

Abstract

The invention provides a pavement drainage system and a construction method thereof. The pavement drainage system comprises a drainage pipe, a roadbed, an obliquely-arranged pavement and a slope protection arranged on the relatively low side of the pavement, the pavement is laid on the upper side of the roadbed, the drainage pipe is pre-buried in the roadbed and the slope protection, the pavement is provided with flow guide holes, the flow guide holes are connected with the drainage pipe, the water outlet end of the drainage pipe extends to the relatively low side of the slope protection; and the surface of the slope protection is provided with a sliding way arranged in the inclined direction. Rainwater on the road surface and the slope protection quickly flows and is drained through the flow guide holes, the drainage pipe and the sliding way, the drainage efficiency is improved, then the road surface and the slope protection are effectively prevented from being washed and permeated by the rainwater, the quality of the road surface and the slope protection is guaranteed, and driving safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of pavement drainage, in particular to a pavement drainage system and a construction method thereof. Background technique [0002] With the development of highway construction, the impact of road drainage on the road is becoming more and more prominent; the accumulation of water on the expressway will reduce the friction between the high-speed vehicle and the ground, resulting in the phenomenon of long braking distance and potential safety hazards. It is not conducive to ensuring the safe driving of the vehicle; in addition, when the vehicle passes through the waterlogged section at high speed, the waterlogged area where the tires of the vehicle pass through will form water mist, which will be sprayed on the subsequent vehicles, which will block the vision of the drivers of the subsequent vehicles and cannot Normal driving increases the risk of driving. [0003] The existing highway drainage method is mainl...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a pavement drainage system and its construction method, which are used to solve the defects of low highway drainage efficiency and seepage damage to the roadbed and slope protection in the prior art, so as to improve the drainage efficiency of the road surface and prevent rainwater from affecting the roadbed and slope protection. The erosion and penetration of the damage to ensure the quality of the pavement
