Pile-tube composite truss type offshore wind turbine foundation and construction process thereof
The invention discloses a pile-tube composite truss type offshore wind turbine foundation. The pile-tube composite truss type offshore wind turbine foundation comprises a truss type structure, a suction barrel and a pile foundation, wherein the suction barrel is connected to the bottom of the truss type structure; and an embedded sleeve for mounting the pile foundation is arranged on the suction barrel. The invention further discloses a construction process for the offshore wind turbine foundation, and the construction process comprises the following steps: lifting and placing the truss type structure, and the suction barrel connected to the bottom of the truss type structure to a seabed, penetrating the truss type structure and the suction barrel into the seabed after being in contact with the seabed until the bottom end of the embedded sleeve is sunk into soil, and forming a sealed space in the suction barrel; performing water pumping operation on the suction barrel, dropping the suction barrel to specified elevation, switching off a suction pump, and sealing a pump connector through a cover plate or grouting measures, thereby accomplishing mounting of the suction barrel; and after the suction barrel is mounted, inserting the pile foundation into the embedded sleeve, and grouting a gap between the pile foundation and the embedded sleeve after pile sinking is accomplished. According to the structure of the offshore wind turbine foundation and a construction method thereof disclosed by the invention, pile-tube composite truss type offshore wind turbine foundation has higherstability and bearing ability, can resist limit load such as a typhoon, and is strong in adaptation to the seabed.
本发明公开了一种桩筒复合桁架式海上风机基础：包括桁架式结构、吸力筒和桩基，吸力筒与桁架式结构的底部相连接，吸力筒上设有安装桩基的嵌入套筒。本发明上述海上风机基础的施工工艺：将桁架式结构、与桁架式结构的底部相连接的吸力筒吊放至海底，接触海床后贯入海床至嵌入套筒的底端没入泥土，吸力筒内形成封闭空间；对吸力筒进行抽水作业，使吸力筒下沉至指定标高，关停吸力泵，并通过盖板或者灌浆措施密封泵接口，完成吸力筒的安装；吸力筒安装完成后，将桩基插入嵌入套筒，沉桩完成后在桩基和嵌入套筒间隙灌浆。该海上风机基础的结构及其施工方法使其具有更高的稳定性和承载能力，更能抵御台风等极限载荷，且海床适应性强。
