Description

Technical Field

[0001] The invention relates to the technical field of deviation correction in caisson construction, in particular to a deviation correction device in caisson construction. Background Art

[0002] During the caisson construction process, due to many factors such as uneven soil quality, asymmetric excavation, uneven force at the blade foot and poor geology, the caisson sinking rate is uneven. The caisson is prone to tilt or offset. If this deviation is not corrected in time, it will lead to subsequent sinking difficulties of the caisson, affecting the final position accuracy of the structure and may also cause uneven force on the well wall, resulting in cracks and other quality problems.

[0003] In the prior art, when correcting the caisson, a weight is directly placed on the highest point of the well wall. The correction force is difficult to control, and stress concentration is likely to occur when force is only applied at one place, causing deformation of the well wall.

A limiting boss is provided at one end of the threaded tube 516 near the limiting plate 513, and an avoidance groove is provided at one end of the through hole of the connecting block 514 near the limiting plate 513. The limiting boss of the threaded tube 516 fits with the avoidance groove of the connecting block 514.
