Offshore wind turbine foundation and grouting construction method thereof
The invention relates to the technical field of electricity generation devices, in particular to an offshore wind turbine foundation comprising grouting assemblies, suction force barrels and a guide pipe frame arranged on the suction force barrels. Each grouting assembly comprises a grouting pipe, a flow distributor and multiple flow distribution pipes which are sequentially connected. Each suction force barrel is provided with a suction force cavity. An opening is formed in the lower end of each suction force cavity. A water drainage opening is formed in the upper end of each suction force cavity. The outlet ends of the flow distribution pipes are arranged on the upper portions of the suction force cavities and are used for conducting grouting towards in the inner portions of the suctionforce cavities. The invention further provides a grouting construction method of the offshore wind turbine foundation, dependence of the wind turbine foundation installation on engineering geology isreduced, the construction effect and the economical performance are improved, the force bearing mode of the suction force barrels is changed, seawater in the suction force barrels is discharged, the effect of sealing the suction force cavities is achieved, a stable force bearing structure is formed below the wind turbine foundation, and stability of the foundation is improved.
本发明涉及发电设备技术领域，尤其涉及一种海上风机基础，包括灌浆组件、吸力桶以及设置于吸力桶上的导管架，灌浆组件包括依次连接的灌浆管、分流器和若干条分流管，吸力桶设置有吸力腔，吸力腔下端设有开口，吸力腔的上端设有排水口，若干条分流管的出口端分别布置于吸力腔上部用于向吸力腔内进行灌浆。本发明还提供了一种海上风机基础灌浆施工方法，减少了风机基础安装对工程地质的依赖，提高施工功效以及经济型，改变吸力桶的受力模式，将吸力桶内的海水排出，达到吸力腔密封的效果，并在风机基础下形成稳定的受力结构，提高基础的稳定性。
