Description

technical field [0001] The invention relates to the technical field of bridge deviation correction, in particular to a traction bridge deviation correction device and a construction method thereof. Background technique [0002] With the progress of urbanization, more and more constructions appear around the existing bridges. For bridge structures, caps and bridge piles are important components for the bridge to support the structural load on the upper part of the bridge and ensure the normal and safe operation of the bridge.

AI Technical Summary

Problems solved by technology

For bridge structures, caps and bridge piles are important components for the bridge to support the structural load on the upper part of the bridge and to ensure the normal and safe operation of the bridge.

If the deviation is not corrected in time, the bridge will continue to tilt, and even affect the safety of the bridge structure and operation

[0003] Although the existing bridge deviation correction devices can effectively solve the bridge structure deviation and safety problems, the general deviation correction devices have a large volume and weight, and they need to occupy a large construction site when used, which has a great impact on road traffic, and installation and construction are also difficult. It is cumbersome and even disturbs the bridge structure during installation

And most of the bridge correction devices need to be equipped with a large-scale reaction frame structure to overcome the reaction force generated by pushing the bridge. However, when the workable space around the bridge piers is small, the existing correction devices and their reaction frames cannot be installed flexibly. To use, it is necessary to go through the cumbersome process of borrowing the construction site and closing the enclosure, and it is impossible to achieve quick rescue and flexible use

In addition, the existing correction device is not sensitive and comprehensive enough to detect the displacement, and cannot timely and accurately feed back the monitoring data to the on-site construction personnel

Application No. 202010176392.2 "A Bridge Pier Column Correction Device Capable of Accurately Controlling the Displacement of Pier Columns" only realizes the deviation correction of the upper structure of the bridge, and lacks the protection of the lower structure of the bridge, and the device needs to install four limit nails Columns, the construction is complicated and occupies a large site, which has a great impact on road traffic

Application No. 201920510126.1 "A Bridge Non-Fulcrum Translation Correction System" only realizes the correction of the bridge beam structure, and lacks the protection of the structure below the beam structure. Bridge deviation is generally caused by the deviation of bridge piers. This patent does not The problem has not been solved fundamentally. At the same time, the cost of building a construction platform is high and the operation is complicated. When the box girder is jacked up, the box girder body will crack, which is extremely risky

Application No. 201921096266.5 "Pushing Support Device for Adaptive Bridge Structure Height Difference" uses the pushing support device to correct the displacement of the bridge. Although it can correct the vertical and horizontal displacements, the stability of itself and the stability of the beam body cannot be guaranteed by the device. , and at the same time effectively ensure that the jacking displacement is lack of monitoring, the construction conditions are complex, the cost is high, and it takes up a large site

[0004] In summary, the current bridge deviation correction devices have problems in construction convenience, flexibility and monitoring accuracy, and cannot be well applied to bridge deviation corrections that require quick rescue or limited surrounding sites, and lack bridge deviation correction devices that are small in size, flexible in installation and use device
