The bottom of the upper chamber is divided into a submersible pump mounting cavity and a manifold setting cavity by a partition plate that is vertically fixed on the top surface of the sealing plate and the inner walls of both sides of the pipe body. This allows the submersible pump (5) to be built into the submersible pump mounting cavity and fixed to the sealing plate by a support. A cooling water pipe is provided in the submersible pump mounting cavity. One end of the cooling water pipe is located at the bottom of the submersible pump mounting cavity, and the other end extends to the top platform (1) for connection with a small pump set on the top platform (1). The suction cylinder connection port K3 and the external connection port K4 are respectively set on the sealing plate and the pipe wall in the manifold setting cavity.

9. The suction cylinder pile driving guide structure for deep-sea applications according to claim 1, characterized in that, The suction cylinder assembly consists of N suction cylinders (7), which are respectively set below each second guide frame leg (301), so that the bottom end of the second guide frame leg (301) is vertically fixed at the center of the top surface of each suction cylinder (7).
