A road pavement drainage method and its drainage structure system

Abstract

The invention provides a road pavement draining method and a drainage structure system. The road pavement draining method is characterized in that water falling on a lane vertically passes through a lane water-permeable surface layer, arrives at a waterproof bonding layer preventing water penetration, and enters into a water-permeable drainage system located at outer sides of drainage curbstones by a cross slope and the drainage curbstones located at outer sides of the lane; the bottoms of the drainage curbstones are provided with water-permeable curbstone bases; the water-permeable drainage system comprises a broken stone blind drain drainage system arranged at the bottoms and the outer sides of the water-permeable curbstone bases; the bottom of the broken stone blind drain drainage system is provided with a longitudinal drainage water-permeable pipe; and most of the water discharged into the water-permeable drainage system at the outer sides permeates into soil at the outer sides and forms ground water, and the rest of the water passes through the longitudinal drainage water-permeable pipe in the broken stone blind drain drainage system and then is discharged into a municipal pipe. The road pavement draining method solves the problem that rainwater on a drainage bituminous pavement is directly discharged into the municipal pipe, and has functional advantages of good safety, ecological benefits, energy saving and good economical efficiency.

Description

technical field [0001] The invention relates to the technical field of road pavement drainage, in particular to a road pavement drainage method and a drainage structure system mainly used for drainage asphalt pavement. Background technique [0002] With the improvement of urban construction and road network, the urban ground coverage rate is getting higher and higher. At present, urban roads are mostly paved with dense and impermeable materials, causing the urban ecological environment to face some outstanding problems: 1) The large amount of rainwater discharge during the rainy season will greatly increase the burden on the urban drainage system; Splashing under the action of vehicles will adversely affect the safety of surrounding vehicles and pedestrians; 3) The dense and impermeable road surface lacks the ability to adjust the temperature and humidity of the urban surface, and the dust pollution is heavy; 4) The road surface blocks the groundwater supply path, making the...
