Embodiment Construction

[0031] see Figure 1-Figure 13 , in this embodiment, the offshore wind power jacket foundation includes four steel pipe piles 1 arranged in a rectangular shape. 12. The lower end of the steel pipe vertical pile 11 is inserted into the mud on the seabed, and at least one reinforcing support 2 is provided between two adjacent steel pipe inclined piles 12. The reinforcing support 2 is X-shaped, and the reinforcing support The two joints 21 on one side of the member 2 are connected to one of the steel pipe inclined piles 12, and the two joints 21 on the other side of the reinforcing support member 2 are connected to the adjacent steel pipe inclined piles 12. The top end of the steel pipe pile 1 A steel platform 3 is provided, and the steel platform 3 is connected to the top ends of four steel pipe inclined piles 12, and a transition section 4 is vertically provided above the steel platform 3, and the transition section 4 is provided with four transition sections along the circumfe...

Abstract

The invention relates to the technical field of offshore wind power engineering, and discloses a method for dismantling the foundation of an offshore wind power jacket, including construction preparation, dismantling of the diagonal bracing of the transition section, dismantling of the transition section, dismantling of the steel platform, dismantling of the reinforcing support, steel The dismantling of the upper part of the pipe pile and the dismantling of the lower part of the steel pipe pile are carried out by dismantling in sections and layers from top to bottom, which makes the selection of marine machinery and equipment more flexible for construction and avoids dependence on large-scale proprietary equipment; In addition, segmental lifting points are set to prevent safety accidents caused by unbalance in the dismantling process. The cutting of underwater steel pipe piles adopts the method of first pumping mud and then cutting steel pipe piles, so as to ensure the accuracy requirements after completion and the navigation requirements of sea areas; Potential safety hazards during the demolition process of the jacket foundation, accurately control the accuracy of the demolition process, and ensure the normal operation and safe navigation of the wind farm during and after the demolition.

Description

technical field [0001] The invention relates to the technical field of offshore wind power engineering, in particular to a method for removing the foundation of an offshore wind power jacket. Background technique [0002] The jacket foundation is one of the main structural types of the offshore wind farm foundation. During the operation of the offshore wind farm, if the jacket foundation is damaged or the design deadline has been reached, the jacket foundation needs to be dismantled. At present, China is in the construction period of offshore wind power, and there is no case of demolition of the jacket foundation. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned prior art, the present invention provides a method for dismantling the foundation of an offshore wind power jacket, which can safely remove the foundation of the jacket. [0004] The technical scheme that the present invention solves its technical problem adopts is: ...
