[0002] At present, when the steel casing of the pile foundation is lowered for installation and driven in, the center of the steel casing is required to keep vertically coincident with the design center of the pile foundation, especially in the construction of underwater pile foundation. The steel casing needs to be extended many times during the follow-up of the erection, and because of the need for hole construction, the coordinate position of the steel casing needs to be tracked and measured in real time, otherwise it is easy to cause the steel casing to deviate from the design center of the pile foundation, and rework is required, affecting the construction speed and work efficiency. During the adjustment process, there will be an error between the actual position and the theoretical position of the steel casing, and after the adjustment, it is necessary to strictly ensure that the plane position deviation of the steel casing is less than 5 cm and the verticality deviation is less than 1%. The current adjustment method is mostly a guide frame.
