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

Embodiment 1

[0052] Such as figure 1 , 2 Shown is the traction type bridge deviation correcting device of the present invention. Among them, the base 1 is fixed by several prestressed anchor rods 2 and provides counter force. Such as image 3 , 4 As shown, the pulling module 3 is composed of a motor 37 , a wire reel 38 , a transverse limiting plate 31 , a longitudinal limiting plate 32 and a transparent skylight 34 . The motor 37 is connected to the wire reel 38 through the transmission shaft 39, and the other end of the wire reel 38 is connected to the transverse limit plate 31 through the limit structure 33, and the bottom of the transverse limit plate 31 and the longitudinal limit plate 32 are provided with bolt holes 7 It is fixedly connected with the base 1 through the bolt 6 connection.

[0053] Such as Figure 5 , 6 As shown, the hoop 4 is made up of a standard block 41 , a corner block 42 and an adjustment block 49 . One end of the standard block 41, the corner block 42 and...

Embodiment 2

[0057] The main difference from Example 1 is that Figure 9 When the platform 82 is convex or other sizes and shapes, the flexible arrangement of the standard block 41, the corner block 42 and the adjustment block 49 can be adapted to different sizes and shapes of the platform 82, which greatly improves the versatility of the device.

Embodiment 3

[0059] The main difference from Example 1 is that Figure 10 When there is an obstacle between the bridge and the traction device and the size of the bearing platform 82 is quite different from that of the traction module 3, the present invention realizes the active deviation correction of the bridge. By changing the position of the splitter 47 and using the turning column 91 to guide The cable 48 is turned to bypass the obstacle area 92 to use the device to correct the deviation, so as to realize the adaptation of the device to various positional relationships of the bridge.

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.
