Viaduct drainage and water treatment system

Abstract

The invention discloses a viaduct drainage and water treatment system. The viaduct drainage and water treatment system comprises a bridge drainage system arranged on the constructed viaduct and an under-bridge water treatment system arranged under the viaduct; the constructed viaduct comprises a bottom supporting system and a girder; the bottom supporting system comprises a front bridge abutment and a rear bridge abutment; the bridge drainage system comprises a drainage system in the longitudinal direction arranged on the girder and two vertical drainage systems respectively arranged on the two bridge abutments; the under-bridge water treatment system comprises a distribution well, a sedimentation tank, a subsurface constructed wetland and an evaporation tank, wherein the distribution well is communicated with the sedimentation tank through a connecting pipeline; the sedimentation tank is communicated with the subsurface constructed wetland through a connecting pipeline; the subsurface constructed wet land is communicated with the evaporation tank through a connecting pipeline; both of the two vertical drainage systems are communicated with a water inlet of the distribution well. The viaduct drainage and water treatment system provided by the invention has the advantages of simple structure, reasonable design, convenient construction, simple use and maintenance, timely surface drainage, good use effect and capabilities of solving the problem of runoff pollution on the viaduct deck and effectively recycling the water resource.

Description

technical field [0001] The invention belongs to the technical field of viaduct drainage treatment, in particular to a viaduct drainage and water treatment system. Background technique [0002] Water treatment ponds are common in the design of expressways. For the pavement drainage of ordinary road sections in China, mortar rubble evaporation ponds are generally installed beside the highway, and the collection of all roadbed water is not considered. It is only used for crossing water bodies with functions such as drinking and breeding. Only when it is time to consider collecting all subgrade drainage. However, there is no design specification for the initial rainwater collection and treatment process in China. Therefore, the existing highway (bridge) surface drainage system is not perfect, especially the drainage effect of the drainage system on the viaduct is poor, the later maintenance cost is high, and the water resources cannot be effectively used, and the waste of water...
