Road drainage structure and construction method

Abstract

The invention discloses a road drainage structure and a construction method. According to key points of the technical scheme, the road drainage structure comprises a roadbed, wherein a water permeablefiltering layer, a drainage cushion layer, a waterproof layer and a base layer are sequentially arranged above the roadbed from bottom to top; and the road drainage structure is characterized in thatdrainage channels are arranged on two sides of the base layer, wherein the upper ends of the drainage channels communicate with the road surface, filter assemblies are arranged in the drainage channels, each filter assembly comprises a plurality of flow guide plates arranged at intervals, and each flow guide plate is inverted V-shaped; and a collection box is arranged between every two adjacent flow guide plates, wherein a plurality of water permeable holes are formed in the bottom and the front side wall of each collection box, and the collection boxes are located on the lower sides of the flow guide plates. According to the road drainage structure and the construction method, the functions of conveniently draining water and easily cleaning garbage can be achieved.

Description

technical field [0001] The invention relates to the field of road construction, more specifically it relates to a road drainage structure and a construction method. Background technique [0002] In order to prevent waterlogging, drainage channels are usually set up on both sides of the road for drainage in urban roads, and filter grids are installed above the drainage channels to prevent garbage from being piled up in the drainage channels to block the drainage channels.
