It can reduce the impact on the atmospheric environment and traffic roads, improve quality and safety, and civilized construction level. It is the development trend of my country's bridge industry. In order to improve the strength and stability of prefabricated bridge pile foundations, bridge pile foundation reinforcement brackets are usually used to reinforce them.

[0003] Chinese patent publication number CN219218740U proposes "a bridge pile foundation reinforcement structure". The technical solution proposes the problem that "in the prior art, when the foundation strength of the pile foundation is insufficient and displacement or settlement occurs, the wire drawing will gradually become loose, and thus cannot play a stable pulling and reinforcing role on the pile foundation, reducing the reinforcement effect of the pile foundation". The utility model provides the following technical solution: "Through the set reinforcement component, the steel cable can be continuously squeezed, so that the steel cable can gradually move from a relaxed state to a tensioned state, so that the steel cable can be in a taut state, which can play a stable connection role between the compression ring and the pile foundation, ensuring that the bridge pier remains in a static and stable state in the pile foundation."

[0004] The above scheme has the following defects: the above device only uses steel cables to stabilize and reinforce the compression ring and the pile foundation, which is not effective and lacks a backup plan. Therefore, a pile foundation reinforcement device for prefabricated bridge design is proposed to solve the above problem. Utility Model Content
