Description

Technical Field

[0001] The present application relates to the field of foundation hoisting, and in particular to a tooling hoist for hoisting a pile bucket composite foundation. Background Art

[0002] The pile-barrel composite foundation is a new type of foundation that combines a large-diameter single pile and a negative pressure barrel. It can effectively reduce the depth of the pipe pile into the soil, improve the foundation's ability to resist horizontal deformation, and obtain a foundation type with higher bearing capacity and stronger adaptability to the marine environment.

[0003] In the prior art, the pile-barrel composite foundation usually adopts the construction method of first driving piles and then sinking barrels during the construction process. The barrel body of the sinking barrel usually includes an inner barrel, an outer barrel, six bulkheads and a top cover plate, wherein the six bulkheads are evenly distributed between the inner barrel and the outer barrel, and the top cover plate is fixedly covered on the top surface between the inner barrel and the outer barrel. The main process of the pile-barrel composite foundation construction is to hoist the inner barrel of the barrel body and sleeve it on the steel pipe pile after the steel pipe pile is installed. At this time, the barrel body will first gradually insert downward into the seabed due to its own weight, and then the barrel body will continue to sink by extracting the air in the barrel. When the barrel body sinks to the seabed, it will sink into the seabed soil due to its own gravity, forming initial mud. At this time, the seawater and soil in the barrel are continuously sucked, so as to prompt the barrel body to further insert downward into the seabed to the designed penetration depth under the action of negative pressure.

[0004] With regard to the above-mentioned prior art, when the barrel body is directly hoisted by ropes, it is not convenient to ensure the stability of the position of the barrel body, and it is difficult to quickly place the inner barrel of the barrel body outside the steel pipe pile, and the work efficiency during the installation of the barrel body is low.
