Description

Technical Field

[0001] The utility model relates to the technical field of positioning and deviation correction, in particular to a positioning and deviation correction device for a cross-bridge steel arch rib. Background Technique

[0002] At present, when construction workers are constructing the steel beam structure of an arch bridge, the position of the steel beam of the arch bridge often shifts left and right or front and back. At this time, a deviation correction device is needed to adjust the position of the steel beam of the arch bridge. In the actual use process of the existing deviation correction device, the steel beam of the arch bridge is usually supported, and then a synchronous hydraulic jack is used to push the steel beam of the arch bridge to move for deviation correction. Although the basic purpose of correcting the deviation of the steel beam of the arch bridge can be achieved, because each time the deviation of the steel beam of the arch bridge is corrected, it can only be corrected in one direction of left and right or front and back. Therefore, when the steel beam deviates in both the left and right and front and back positions, it is necessary to support the steel beam of the arch bridge again after correcting the deviation in one direction, disassemble the synchronous hydraulic jack, and then install the synchronous hydraulic jack in a different direction for secondary deviation correction, which increases the working intensity of construction workers and brings inconvenience to construction workers.

[0003] However, when the existing positioning and deviation correction is used, there are still some problems:

[0004] When the existing bridge is under construction, its columns are directly inserted into the soil without any fixation. Due to the soft soil, after long-term use, the columns will shake.

[0005] In view of the above problems, innovative design is carried out on the basis of the original positioning and deviation correction. Content of the Utility Model
