AI Technical Summary
Technical Problem
[0004]本实用新型的目的在于提供一种受限条件下斜拉扣挂施工背索排布结构，旨在解决传统背索在受限条件下锚固点有限、受力不均、施工难的问题
Benefits of technology
[0007] Highly adaptable and effectively addresses constrained conditions: This utility model adopts a design that combines a permanent and temporary anchoring system with a newly constructed rock anchoring system. It makes full use of the bridge's own permanent structural components such as abutments and pier caps as anchoring points, reducing the occupation of temporary sites. Furthermore, by casting rock anchoring systems on both sides of the mountain, it solves the problem of insufficient anchoring points under complex terrain. It can flexibly adapt to bridge projects with limited terrain and complex construction conditions, and has a wide range of applications.
