Construction method of offshore wind power single pile foundation
The invention relates to the technical field of offshore wind power building construction, and particularly discloses a construction method of an offshore wind power single-pile foundation, which comprises the following steps of: firstly, mounting a foundation pile on a pile position, and ensuring the construction directionality of the foundation pile by using a positioning platform, so that the foundation pile is gradually submerged into a liquid surface and a mud surface; after the foundation pile stops diving, a vibratory hammer is installed, and the foundation pile is continuously dived through the vibratory hammer until the bottom of the foundation pile makes contact with a seabed bedrock layer; then grouting is utilized to form a grouting reinforcing body on the outer side of the foundation pile; the grouting reinforcing bodies are sequentially formed from bottom to top, and the grouting reinforcing bodies in different layers form a whole; and after grouting is completed, the grouting equipment is dismantled, the top of the foundation pile is connected with the wind turbine generator tower, and construction is completed. According to the construction method provided by the invention, a plurality of layers of grouting reinforcement bodies are formed at the bottom of the foundation pile in a grouting manner, and the grouting reinforcement bodies form a whole, so that the foundation pile is combined with the seabed foundation, and the purpose of quickly reinforcing the foundation pile is achieved.
本发明涉及海上风电建筑施工技术领域，具体公开了一种海上风电单桩基础的施工方法，包括如下步骤：先将基础桩安装在桩位上，利用定位平台保证基础桩施工的方向性，使基础桩逐渐潜入液面和泥面中；待基础桩停止下潜后，安装振动锤，利用振动锤使基础桩持续下潜，直至底部与海底基岩层接触到；之后利用灌浆，在基础桩外侧形成注浆加固体；注浆加固体从下向上依次形成，不同层的注浆加固体相互形成一个整体；注浆完成后拆除注浆设备，并将基础桩顶部与风电机组塔筒相连，完成施工；本发明所提供的施工方法，利用注浆的方式在基础桩底部形成若干层注浆加固体，注浆加固体形成一个整体，使基础桩与海底的地基相结合，达到快速加固基础桩的目的。
