Abstract

The invention discloses an offshore large-diameter steel pipe pile erecting method and device. The offshore large-diameter steel pipe pile erecting device comprises a pile driving guide frame, a hoisting mechanism, a pile driving frame, a straightening mechanism and a positioning mechanism. According to the offshore large-diameter steel pipe pile erecting method and device, the purpose of erectinga steel pipe pile into a vertical state is achieved by adopting the mode that a pile hoisting auxiliary device is mounted on the pile driving guide frame to hook the bottom of the steel pipe pile, the hoisted position of the steel pipe pile is hooked through external lifting equipment, a steel wire rope of the pile hoisting auxiliary device is descended gradually, and a steel wire rope of the external lifting equipment is ascended gradually, by adopting a process, the performance requirement of an offshore wind power large-diameter steel pipe pile for steamer machine equipment can be greatlylowered, meanwhile the berthing positions of the steamer machine equipment are reduced, a pile driving platform is pile erecting auxiliary equipment and also a pile erecting limiting device, and the pile erecting and steel pipe pile berthing efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of offshore large-diameter steel pipe pile construction, in particular to an offshore large-diameter steel pipe pile erection method and a pile erection device. Background technique [0002] In the construction process of offshore wind power foundation, single pile foundation has been widely used because of its high bearing capacity, convenient construction, high construction efficiency and many other advantages. With the increasing installed power of offshore wind power, the diameter and pile length of single pile foundations are also increasing, and higher and higher requirements are placed on construction marine equipment. For some offshore wind power projects, domestically available There are very few marine machinery and equipment, which to a certain extent has caused the situation that "offshore wind power construction needs to wait for offshore wind power construction equipment", which directly result...
