Description

Technical Field

[0001] The utility model relates to the technical field of reinforced bridge piers, in particular to reinforced bridge pier supports in bridge and tunnel engineering. Background Art

[0002] In bridge and tunnel projects, the reinforcement of pier supports is a very important link, especially for single-column continuous box girder bridges, because they are prone to adverse situations such as support loss and main beam slippage under the action of overloaded vehicles, and may even lead to safety accidents such as bridge instability and overturning. Therefore, it is necessary to reinforce these bridges and ensure that the newly added supports are tightly connected to the upper structure box girder and can withstand a certain initial pressure.

[0003] For example, a bridge tunnel engineering reinforcement pier support provided in the Chinese patent application with application number 202310569222.4 includes a supporting pier, a supporting frame for supporting the bridge is fixedly installed on the upper end of the supporting pier, and a base is fixedly installed on the lower end of the supporting pier. A plurality of steel bar holes for connecting with steel bars are opened on the lower surface of the base. The technical solution is achieved by burying the base in the foundation, and connecting the steel bar holes provided on the lower surface of the base to the embedded steel bars in the foundation. Then the staff uses a crane to place the bridge on the supporting frame. After the bridge is placed on the supporting frame, with the cooperation of the reinforcement assembly, the fixing effect between the supporting frame and the supporting pier is greatly enhanced, thereby avoiding the occurrence of fractures between the bridge support and the pier support when there are many cars passing on one side of the bridge. This not only effectively reinforces the bridge, but also avoids the occurrence of major accidents.
