Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of bridge deviation correction, and more specifically, relates to a bridge deviation correction pushing and sliding device. Background Art
[0002] After years of service, existing multi-span bridges may experience deviations in the upper beams and the bridge deck pavement due to factors such as heavy vehicles, curves, or deformation of the middle piers. The beams must then be corrected. The traditional correction construction method is direct jacking, which involves directly applying a horizontal jacking force to the beams, which reacts to the large bridge piers or abutments of the side spans. The beams and piers are replaced with ordinary steel sliders through jacking. The problem with the above solution is that this correction method generates a horizontal thrust at the top of the middle span high pier during the jacking process. When this horizontal thrust is large enough, it generates a large bending moment at the bottom of the high and flexible piers, resulting in circumferential cracks at the bottom of the piers, and even the risk of the piers collapsing and the beams falling.
