Drainage device for highway bridge

Abstract

The invention discloses a drainage device for a highway bridge. The device comprises a soil base layer, a highway main body is arranged at the upper end of the soil base layer, a bridge main body is arranged above the highway main body, pier stand columns are arranged at the lower end of the bridge main body, the bridge main body is fixedly connected with the pier stand columns, and the pier stand columns are fixedly connected with the highway main body; the number of the drainage ditches is two, the two drainage ditches are located on the two sides of the road body respectively, water collecting pipes are arranged in the drainage ditches, and water inlets are formed in the upper ends of the drainage ditches; a water collecting mechanism comprises a first water collecting disc, a second water collecting disc and a third water collecting disc, the first water collecting disc, the second water collecting disc and the third water collecting disc are equal in size, drainage vertical pipes are arranged at the lower end of the water collecting mechanism, and the lower ends of the drainage vertical pipes are embedded into the drainage ditches. The efficient and rapid drainage is achieved, and the problems that water is accumulated on the road surface and a drainage opening is prone to being blocked are solved.

Description

technical field [0001] The invention relates to the technical field of highway bridge drainage, in particular to a drainage device for highway bridges. Background technique [0002] Highway bridge engineering (highway bridge engineering) refers to the planning, design, construction, maintenance, repair and other work of structures that cross waters, valleys and all traffic passages. With the development of my country's transportation industry, highway lines cross rivers , harbors, lakes, reservoirs, irrigation canals and other waters, or across deep valleys with large height differences, or across other traffic routes, in order to maintain smooth traffic, bridges need to be erected. Highway bridges are special road structures that can cross terrain. It has become a very important part of transportation development, and drainage facilities are an indispensable part of highway bridges. [0003] The structure of the existing drainage device is simple, the drainage efficiency is ...
