Fabrication and hoisting construction technology of reinforcement cage for large diameter and super long pile foundation
For the 100m super long reinforcement cage, if it is installed in sections and the hoisting time is long, it is easy to cause the hole collapse of underwater bored cast-in-place pile; If the reinforcement cage of bored cast-in-place pile is installed in two sections, the welding connection time of reinforcement cage can be reduced and the construction can be faster, so as to reduce the risk of hole collapse of underwater bored pile Appropriate reinforcement cage hoisting method must be adopted for this method
