During the lifting process of the pile foundation, a certain swing will be generated, and then the support arm will be subjected to a certain lateral force. The method of directly locking the base with bolts has limited effect on lateral support, and thus the ability to suppress overall tipping is not ideal. If a method of forming a support on the side of the base is adopted, the lateral support capacity of the base can be improved.

[0004] In view of this, the present utility model is proposed. Utility Model Content
