Novel linear drainage ditch structure for permeable drainage pavement

Abstract

The invention discloses a novel linear drainage ditch structure for permeable drainage pavement. The novel linear drainage ditch structure comprises a resin concrete ditch body. The resin concrete ditch body is arranged at the outer side of a water impermeable base layer of a road. A road drainage asphalt surface layer is fixed right above the water impermeable base layer by means of a waterproof adhesive layer. The upper edge of the resin concrete ditch body is flush with the upper surface of the road drainage asphalt surface layer. Drainage holes distributed at equal intervals are formed in the ditch wall of the side, close to the road drainage asphalt surface layer, of the resin concrete ditch body. A resin concrete cover plate is arranged at the upper half part in the channel of the resin concrete ditch body. Multiple groups of sewage intercepting weir units distributed at equal intervals are arranged at the bottom of the channel of the resin concrete ditch body. The novel linear drainage ditch structure can meet the requirements of water permeation and drainage of permeable drainage pavement, and also has sewage intercepting and cleaning functions to prevent solid particles smaller in size from going into a municipal sewage drain pipeline network along with rainwater; this structure is simple and easy to implement, and has favorable application prospect.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a novel linear drainage ditch structure for permeable drainage pavement. Background technique [0002] With the proposal of the concept of sponge city, the Ministry of Housing and Urban-Rural Development requires the construction of a sponge city with natural accumulation, natural infiltration and natural purification. As one of the important components of the low-impact development facilities of the sponge city, permeable pavement plays a role that cannot be ignored. Local governments are also actively responding to the call of the central government to plan and construct permeable pavement. Taking Nanjing as an example, the "Implementation Opinions on Promoting the Construction of Sponge City" requires that in the hardened area of ​​newly built and rebuilt communities, the permeable pavement rate should not be lower than 40%; , The permeable pavement rate should not b...

Problems solved by technology

[0008] The purpose of the present invention is to overcome the problem that the existing linear drainage ditch easily causes water accumulation on the road surface and cannot realize the interception and purification of rainwater in the middle
