Shallow sea wind electricity facility force absorption pile

Abstract

The invention provides a shallow sea wind electricity facility force absorption pile, and belongs to the field of ocean equipment. The pipe comprises an outer cylinder, grouting pipes, an inner cylinder, a vacuum pump, a one-way valve, an upper arc-shaped body, a lower arc-shaped body and plugs. The grouting pipes are installed between the outer cylinder and the inner cylinder. The outer cylinder, the inner cylinder and the grouting pipes are fixed to be a whole through linear laser welding, and stress on welding portions is eliminated through Hawking. The upper arc-shaped body and the lower arc-shaped body are welded in the inner cylinder, wherein the upper arc-shaped body is provided with the vacuum pump, the lower arc-shaped body is provided with the one-way valve, and the lower ends of the grouting pipes are provided with the plugs. The eight grouting pipes are uniformly distributed between the outer cylinder and the inner cylinder. The plugs are cone-shaped and are made of magnetic steel. Welding line stress elimination can be achieved on the upper arc-shaped body and the lower arc-shaped body which are welded in the inner cylinder through Hawking. The outer cylinder and the inner cylinder are both big-end-up and are cones with force absorption characteristics. The pile is simple in structure, convenient to insert, large in bearing capacity and little in pile pulling resistance, construction difficulty is the same as that of a cylindrical leg pile, all principles and theories which are used are simple and mature, and reliability of the device is high.

Description

technical field [0001] The invention relates to a shallow sea wind power facility suction pile, which belongs to the field of marine equipment. Background technique [0002] The development of offshore wind power facilities is affected by the harsh environment of the ocean, maintenance is difficult, and the cost of power generation is high, which inhibits the development of offshore wind power facilities. Offshore wind power facilities are subject to the dual effects of environmental loads and wind turbine loads. It is necessary to comprehensively consider the dynamic characteristics of environmental loads such as wind, waves, and currents. The effect of the action on the foundation of offshore wind power is a complex load action system, and the effects of various influencing factors are mutual coupling and mutual influence. Exploring the dynamic characteristics of offshore wind power generation facilities under complex wind turbine loads and environmental factors, and rese...
