Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving material production, in particular to a steel structure bridge pier across a highway. Background Art

[0002] Bridge piers are substructures that support the bridge span structure and transmit dead loads and vehicle live loads to the foundation. Bridge abutments are located on both sides of the bridge, and bridge piers are located between the two abutments. Currently, there are many accidents in which vehicles collide with bridge piers in traffic accidents. Therefore, how to solve the problem of vehicle collisions with bridge piers has become one of the problems that need to be solved urgently. The collision between vehicles and bridge piers not only causes great harm to vehicles and people, but also damages the base of the piers, thereby affecting and weakening the bearing capacity of the base of the piers, and further affecting the overall stability and safety performance of the piers. At the same time, the current steel structure bridge piers are relatively cumbersome during the maintenance process, and most of the maintenance work is carried out with the assistance of slings and safety ropes. Not only is the work cumbersome but also the efficiency is low. Therefore, we have introduced a new steel structure bridge pier for highways. Utility Model Content
