Problems solved by technology

For the construction of pile foundations in water, it is usually to build a platform or build a cofferdam on the horizontal surface, and then carry out the construction of the pile foundation. Large amount, long construction period, and the construction of cofferdams has a large impact on the water environment and other shortcomings
There are also large-scale floating cranes or piling ships to assist bridge pile foundation construction, but for some closed waters, it cannot be adapted and the cost is relatively high

Abstract

The invention belongs to the technical field of underwater pile foundation construction. The ultra-long large-diameter pile foundation underwater operation platform unit comprises a supporting barrel and a cantilever positioning guide frame, a guide assembly is arranged on the cantilever positioning guide frame and used for conducting radial limiting supporting on the supporting barrel, a supporting assembly is arranged on the supporting barrel, and the supporting assembly is used for supporting the supporting barrel. The supporting assembly is used for supporting the cantilever positioning guide frame. The invention further discloses a super-long large-diameter pile foundation underwater operation platform and a construction method. The overall arrangement is reasonable, the problems existing in construction of an existing ultra-long large-diameter pile foundation operation platform can be effectively solved, the structural stability and the construction efficiency are improved, modular arrangement can be achieved, and construction and control over the structural stability are more convenient.

Description

technical field [0001] The invention belongs to the technical field of underwater pile foundation construction, and in particular relates to an underwater working platform unit, a working platform and a construction method for a super-long diameter pile foundation. Background technique [0002] As the load-bearing structure of the bridge, the pile foundation bears all the loads of the superstructure. Among them, steel pipe piles or bored cast-in-place piles are widely used in the construction of bridge pile foundations with high bearing capacity, especially in underwater engineering. For the construction of pile foundations in water, usually a platform or cofferdam is built on a horizontal surface, and then the construction of the pile foundation is carried out. These construction methods are highly reliable and can ensure the safety and quality of the pile foundation. It has disadvantages such as large quantity, long construction period, and great impact on the water envir...
