AI Technical Summary
During the construction of the caisson, the caisson descends under its own weight, which can easily cause it to tilt when the soil around the bottom of the caisson is excavated at different depths.
The method involves installing an abutment plate and a drive assembly on the well casing. Through the cooperation of a cam and a rotating rod, the abutment plate is ensured to abut against the inner wall of the well pit when the soil at the bottom of the well casing is excavated, ensuring that the excavation depth is consistent each time. After the soil around the bottom of the well casing is excavated evenly, the cam is rotated in the opposite direction to make the well casing fall down by gravity.
It effectively reduces the tilting of the well casing during the descent process, improving the stability and fixation effect of the well casing during descent.
