Jacket with construction suction cylinders and construction method thereof

Abstract

The invention discloses a jacket with construction suction cylinders and a construction method thereof. The jacket includes the construction suction cylinders which are arranged in a regular polygon,a truss jacket body on the upper parts of the construction suction cylinders and external pile sleeves fixed to the construction suction cylinders. When the jacket with the construction suction cylinders are in construction, the truss jacket body, the construction suction cylinders, upper and lower hoof-shaped yoke plates, the pile sleeves and cutting plates are made in a factory, all the membersare welded into the integral jacket, the integral jacket is positioned and lifted to a seabed, columns of the jacket body are vacuumed to sink the integral jacket body, the integral jacket body is leveled, stressed piles are hit into the integral jacket body through the pile sleeves, and finally, the stressed piles are connected to the pile sleeves through annular grouting so as to form a stable foundation. Through the construction method of the invention, the jacket is stabilized during a construction period by using the construction suction cylinders, which saves pile clamping devices required for a jacket by a ''post-pile method'' and relevant construction links and has the advantages of fast and safe construction and good economy.

Description

technical field [0001] The invention relates to the field of marine engineering, in particular to a jacket and a construction method thereof. Background technique [0002] Among the structural types of marine engineering foundations, the jacket is the most commonly used form of foundation structure. Its function is to provide support for the upper facilities and maintain stability. At present, it is mainly a steel structure truss. As the foundation of the wind turbine, the jacket must be leveled during installation, and its level accuracy directly affects the safety, adaptability, service life and other performances of the offshore wind turbine. The leveling and installation process of the jacket in deep water includes the leveling stage and the clamping stage. During construction, a special leveling and clamping system is required to level and stabilize the jacket. Pile device also involves relevant clamping pile construction link, its construction is complicated, and cons...
