AI Technical Summary

Technical Problem

In traditional bridge construction, gaps are prone to appear in the connection between the pier and the support base, leading to uneven load distribution, stress concentration and corrosion problems. Moreover, the existing rigid support base is difficult to adapt to the flatness error and settlement deformation of the pier.

Method used

A bridge concrete pier support base was designed, which adopts a floating plate and a composite damping system. Through the combination of ball head structure and spring, three-dimensional fine adjustment is achieved to eliminate gaps and provide flexible support and damping absorption under static and dynamic loads.

Benefits of technology

It effectively eliminates gaps, avoids stress concentration, simplifies the construction process, reduces flatness requirements, and improves structural stability and service life, making it particularly suitable for complex geological conditions.
