Description

A stable bridge height limiting device

technical field

The utility model relates to the technical field of height limiting devices, in particular to a stably placed height limiting device for bridges.

Background technique

A bridge (bridge) refers to a building built for roads to cross natural or artificial obstacles. It is erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. A bridge generally consists of a superstructure, a substructure and ancillary structures. The superstructure mainly refers to the bridge span structure and support system; the substructure includes abutments, piers and foundations; , diversion engineering, etc. According to the structural system of bridges, there are four basic systems: girder bridge, arch bridge, rigid frame bridge, and suspension cable load-bearing (suspension bridge, cable-stayed bridge).

Bridge height limit is the main measure to restrict large vehicles from passing through important bridge sections. Every year, important bridges are crushed due to unrestricted large vehicles, and then a lot of money is spent on maintaining bridges, which affects traffic. Most of the existing bridge viaducts have fixed height-limited beam heights, which restrict the passage of large vehicles and also hinder special vehicles in special periods, such as fire trucks and sprinklers, which cannot be flexibly controlled.
