Intelligent Negative Pressure Sinking Construction Technology for Suction Tube Jacket
In recent years,the offshore wind power construction area has gradually developed in the direction of offshore and deep-water construction,and the fixed infrastructure form of offshore wind power has also developed from a monopile structure to a pipe frame structure.The suction tube jacket is one of the new offshore wind power infrastructures,and the sinking of the suction tube foundation is the key process in the construction of the tube jacket structure.Combined with the example of the foundation sinking construction of the suction tube jacket of an offshore wind power project,a new type of intelligent negative pressure machine was selected,and the working principle,process flow,system composition,pipeline layout,system installation,specific sinking operation,and system recovery after completion of the new intelligent negative pressure machine system were emphatically discussed.In practice,it has achieved good results of installing a suction tube jacket in 9 hours,which has laid a good foundation for the subsequent large-scale promotion of intelligent negative pressure machines in offshore wind power foundation construction.
