Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, and more specifically, to a walking-type jacking and correction structure for the construction of bridge steel box girders. Background Technology

[0002] In bridge engineering, steel box girders typically need to be pushed forward in a step-by-step manner along a designed circular curve, and finally connected after multiple segments have been pushed into place. However, due to various factors such as foundation settlement and wind load, the steel box girder may shift laterally and deviate from the predetermined pushing route, making precise connection impossible.

[0003] Traditional lateral offset correction methods primarily rely on manual experience to determine the correction distance when lateral offset is detected during the docking phase, and then... Figure 3 The walking-type jacking architecture shown in the figure drives the correction process. Although it can meet the docking requirements to a certain extent, its error rate is still relatively large, and it cannot detect deviation trends in a timely manner. Excessive delay in detection can easily lead to additional workload and low overall operation efficiency. Utility Model Content
