Precision pile sinking foundation structure of underwater engineering and underwater chute pile foundation structure construction method
The invention discloses a precision pile sinking foundation structure of underwater engineering. The pile foundation is formed by continuously connecting lower PHC piles with upper steel pipe piles through bearing parts between the PHC piles and the steel pipe piles, wherein the PHC piles and the steel pipe piles have the same outside diameter; the bearing parts are pre-fixed on the tops of the PHC piles; the steel pipe piles are welded and fixed on the bearing parts. The pile foundation structure can be flexibly applicable to solution of pile foundation construction deviation caused by geological changes; therefore, underwater welding or cutting is conveniently carried out, and temporary cofferdam or a sleeve box for forming dry field construction conditions is saved; the structure is ensured for smooth underwater construction of the chute structure; the problem of structure durability is solved; underwater pile connection or cutting is conveniently carried out; a plurality of purposes such as reliable structure, reduction of process, reduction of construction cycle, safe construction and cost saving are achieved; the structure can be popularized and applied in large shipbuilding and repair yards.
