Drainage system for highway bridge

Abstract

The invention discloses a drainage system for highway bridges, which includes sidewalks, sewage tanks and water filter tanks; multiple sidewalk drainage wells are arranged on the original highway bridges, and the water in the drainage wells is discharged through water distribution pipes and bends respectively, which can Quickly discharge the accumulated water on the sidewalk, and set up a number of sewage tanks on the roadway, which can filter and purify the water in the sewage tank in the water storage tank. Drainage. In the rainstorm environment, there is a lot of water inside the water storage tank. The water is discharged through the flood discharge pipe and the filter outlet to improve the drainage efficiency. This method has little environmental pollution and can quickly remove the water accumulation on the road bridge. Reduce water accumulation on highway bridges, reduce the impact of water flow on roadbeds and road surfaces, improve the service life of highway bridges, and make pedestrians and vehicles passing through highway bridges safer.

Description

technical field [0001] The invention belongs to the technical field of drainage facilities, and in particular relates to a drainage system for highway bridges. Background technique [0002] Drainage system refers to the overall combination of drainage collection, transportation, water quality treatment and discharge and other facilities in a certain way. The general term for all levels of drainage ditches and buildings used for waterlogging, waterlogging and salt prevention. The layout of the drainage system should be comprehensively planned, and the drainage ditch should be located at the lowest point of the control area as far as possible, so as to achieve self-flowing drainage as much as possible. According to the terrain, the drainage area should be divided into high, medium and low areas to achieve high water and high drainage. Low water and low discharge, mainly self-drainage, supplemented by pumping, the outlet of the main drainage ditch should be selected in a place...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a drainage system for highway bridges, to solve the problem that the original highway bridge drainage system proposed in the above background technology cannot achieve fast drainage in the rainstorm environment, when the water flow cannot be quickly discharged from the highway bridge , rainwater will form accumulation in the front, causing road surface water to infiltrate, causing different degrees of damage to the roadbed and pavement of road bridges, resulting in a decline in the usability and safety of road bridges, and bringing safety hazards to the use of road bridges
