Description
Technical Field
The utility model relates to the technical field of offshore construction equipment, in particular to suction pile negative pressure cylinder injection equipment.
Background
Because the requirement for environmental protection is continuously severe, offshore wind power in China develops rapidly in recent years, and according to statistics, the current single-pile foundation exceeds 65% in the global offshore wind power foundation form, so that the method is the most applied wind power foundation form. With the development of the offshore wind turbine power towards large-scale, the geological conditions of the site are poor, the wave force is large, the pile diameter, the pile length and the pile weight of a single-pile foundation are further increased, but the offshore construction equipment matched with the pile diameter, the pile length and the pile weight are less, the construction cost is high, and the development and utilization of offshore wind energy resources are restricted.
Along with the increase of water depth, the length of a cantilever of the water middle section of the single-pile structure is correspondingly increased, and under the action of upper wind, wave and current loads, the deformation of a cantilever section pile body is very obvious, so that a wind turbine generator which is tall up to 200 meters generates very large horizontal shaking, and the engineering safety is seriously influenced. The suction bucket foundation is widely applied to offshore and offshore projects due to high rigidity, strong deformation resistance, convenience in installation and high comprehensive bearing performance, but the penetration depth of the suction bucket foundation is shallower than that of a pile foundation, the requirement on the bearing capacity of a shallow soil body is high, and the suction bucket foundation is independently utilized as an offshore wind power foundation to have greater risk. At present, the composite foundation structure form combining the pile and the suction bucket is adopted, the respective advantages of the pile and the suction bucket are fully exerted, the deformation of a central large-diameter single pile under extreme load is reduced through the huge rigidity of an external suction bucket structure, the integral rigidity and the natural vibration frequency of a fan foundation are increased, and then the pile diameter or the pile length is reduced, so that the construction solution is realized, and the application is realized.
