Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge reinforcement, in particular to a reinforcement device for highway bridges. Background Art
[0002] Most of the existing highway bridge pile foundations are affected by natural geographical conditions, usage time, and especially the impact of water flow. The impact force of water flow on the bridge pile foundation will reduce the stability of the bridge pile foundation over time, and then destroy the structure of the bridge pile foundation, causing safety hazards to the entire bridge and its stability will be reduced. It is necessary to strengthen the bridge structure.
[0003] After searching the Chinese patent with the announcement number CN215441990U, a reinforcement device for highway bridge pile foundation is disclosed. The threaded rod is arranged to drive the threaded sleeve to rotate, and the threaded sleeve drives the connecting rod to stretch inward. At the same time, the connecting rod also drives the shell to stretch inward to support the pile foundation and avoid the pile foundation from tilting. By arranging side plates, the two sides of the pile foundation can be supported to improve its stability. By arranging the above structure, the advantage of adjusting the fixed height is obtained, which solves the problem that the existing pile foundation reinforcement device does not have the ability to adjust the fixed height, thereby facilitating the use of the device.
[0004] Based on the above search and combined with the prior art, it was found that the above patent has certain defects. When in use, the side reinforcement structures such as the side panels cannot change with the adjustment of the shell height. There is no structural connection between the side panels and the shell, and the shells on both sides are fixed and spliced only by fixing bolts. The overall contact area is small and easily damaged when under pressure. The stability is poor, which reduces the reinforcement efficiency of the highway bridge. Utility Model Content
