AI Technical Summary

Technical Problem

Existing U-shaped bridge abutment structures are prone to cracks and safety hazards in areas with weak stress. Traditional reinforcement methods are complex to construct, occupy space, and have unstable connections, affecting traffic and safety.

Method used

The bridge abutment adopts a modular prefabricated assembly truss structure. The truss units are assembled with high precision in the factory and connected on site using high-strength bolts. Combined with fixed chemical anchors and tie rods, a self-balancing system is formed, which enhances the overall stability and load-bearing capacity of the abutment.

Benefits of technology

It enables rapid construction, improves the overall stability and load-bearing capacity of the bridge abutment structure, prevents crack propagation and safety hazards, reduces construction difficulty and safety risks, and allows for the recycling of resources.

Abstract

This utility model discloses a prefabricated truss structure for reinforcing U-shaped bridge abutments, including a front wall truss unit located at the front wall of the U-shaped bridge abutment, side wall truss units symmetrically arranged at the side walls on both sides of the bridge abutment, and an anchoring unit. The side wall truss unit includes a first upper and lower chord and a first vertical member, and the side wall truss unit includes a second upper and lower chord and a second vertical member. One side of the first upper and lower chord and the second upper and lower chord protrudes beyond the first and second vertical members. This protruding part is an extension section with bolt holes, which connect adjacent truss segments by bolts. The anchoring unit includes a fixed chemical anchor that anchors the front wall truss unit and the side wall truss unit to the bridge abutment body as a whole, and a tie rod between the side wall truss units on both sides of the bridge abutment. It serves as a connector for the side wall truss units, connecting the truss structures on both sides to form a frame-type clamp. By prefabricating truss segments in advance, modular assembly of the truss structure is achieved.
