AI Technical Summary
The existing connection structure of prefabricated concrete bridge piers is insufficient in terms of strength and complexity. In particular, cement mortar cannot significantly improve the structural integrity and connection strength of the bridge piers, and the simple structure of the connectors makes it difficult to resist lateral impact forces.
The UHPC steel pipe connectors are used, and a multi-layer composite connection structure is formed by setting up a steel cage unit, an upper UHPC layer unit and a perforated steel plate unit inside the steel pipe unit, combined with steel reinforcement binding and welding, which enhances the connection strength and stability of the pier and abutment.
It provides a high-strength and stable connection effect, improves the integrity and impact resistance of the bridge pier structure, and ensures the stability and durability of the connectors under various stresses.
