The pile-first method is a mode of piling first and then placing a jacket, has higher requirements on pile sinking positioning precision and construction precision of the jacket, and generally needs to place a pile sinking positioning guide platform for auxiliary positioning in order to ensure that the verticality of a pile sinking is controllable and adjustable. With the continuous increase of the water depth of the construction area, the application of the pile-first method is gradually increased. In the prior pile method jacket construction, the precision control of pile sinking and the leveling of a jacket are very difficult links, the common method in the industry at present is to build a pile stabilizing platform or a guide frame firstly and then carry out the pile sinking operation, but the pile stabilizing platform or the guide frame belong to large structures, a large crane ship is needed for hoisting, the adjustment of the verticality and the levelness of the whole platform is very inconvenient, and the construction progress of the whole project is seriously influenced.
