Highway drainage system and construction method

Abstract

The invention discloses a highway drainage system and a construction method. The highway drainage system includes a drainage pipeline system, wherein the drainage pipeline system includes a flow guiding pipeline which includes pervious beds arranged in drainage ditches of the roadsides of a highway, a plurality of flow guiding pipes communicating with the bottom ends of the pervious beds and arranged below the highway, a greening pipeline and an intelligent monitoring system, wherein the greening pipeline includes a water pumping pipe, a water collecting tank and dispersed flow pipes, the water pumping pipe communicates with the flow guiding pipe through liquid, the water collecting tank communicates with near adjacent 4-6 water pumping pipes through liquid, the dispersed flow pipes include the main dispersed flow pipe and the sub dispersed flow pipe communicating with the main dispersed flow pipe and the water collecting tank, the main dispersed flow pipe and the sub dispersed flow pipe are arranged in curbstones of the two sides of a green belt of the middle of the highway, a first water pump and a second water pump are correspondingly arranged on the water pumping pipe and the sub dispersed flow pipe. According to the highway drainage system and the construction method, a road surface water collecting system is established for vegetation irrigation of the green belt in the middle of the highway, the problem of road surface drainage is solved, and meanwhile the problem of vegetation irrigation is solved.

Description

Technical field [0001] The invention relates to the technical field of road construction, in particular to a highway drainage system and a construction method. Background technique [0002] With the development of my country’s economy, people’s living standards continue to improve, and high-speed travel is becoming more frequent. As a result, the requirements for expressway pavement design technology and quality are also increasing. The design, construction and maintenance of pavement The service life of the expressway has a great influence. Among them, the design of the expressway drainage system has a decisive influence on the service life of the expressway. It can be known from the construction of highways in the past that an important factor that affects the performance and life of the road surface is water. The poor design of the highway drainage system will cause the problem of highway water damage to become increasingly prominent, and seriously cause the road section to be ...

AI Technical Summary

Problems solved by technology

[0004] Another object of the present invention is to provide a highway drainage system and construction method. By establishing a road surface drainage collection system, it can be used for vegetation irrigation in the green belt in the middle of the highway, which not only solves the problem of road surface drainage, but also solves the problem of vegetation irrigation.
