After the core upright post 2 and the middle upright post 3 of the pile bottom 1 are separated, the sealing sheet 13 and the lifting sealing column 14 can be restored to the original state, so that the interior of the pile bottom 1 is in a sealing state, and sand and stones at the bottom of a river bank are prevented from entering the interior of the pile bottom 1.

Twenty-four steps: and after all the structures are dismantled, carrying out regular maintenance and classified storage.

Twenty-five steps: and if the underwater structure needs to be maintained and reinforced, the core upright column 2 and the middle upright column 3 are directly connected with the corresponding pile bottom 1.

Twenty-six steps: and repeating the eighth step to the eighteen steps, and providing a working site for maintenance and reinforcement construction by adopting the water isolating system.

Twenty-seven steps: and when the maintenance and reinforcement are completed, repeating the nineteen steps to the twenty-four steps, and dismantling and storing the automatic tensioning water-resisting system.

In conclusion, the combined type water-resisting device provided by the invention is convenient to disassemble, assemble and operate, can be recycled, is economic and environment-friendly, and reduces the construction cost of the device to a greater extent.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
