The invention relates to the technical field of ocean engineering, and provides a high-pulling-resistance spiral pile for mooring a tension leg floating type draught fan and a construction method of the high-pulling-resistance spiral pile. The drill bit is arranged at the bottom end of the screw pile body; the mooring pile cap is arranged at the top end of the screw pile body, and a mooring rope for mooring is stored in the mooring pile cap; and the transmission connecting piece is mounted at the top of the mooring pile cap, is connected with an external power source, and transmits torque to the screw pile body and the drill bit. According to the scheme, the axial pulling resistance of the anchoring foundation is remarkably improved through the spiral pile structure. A piling method is not needed, use of large special equipment is avoided, the construction efficiency is greatly improved in the drilling construction process, and large-scale application is facilitated. The mooring rope and the mooring pile cap are connected together and stored in the pile cap, connection of the lower portion of the mooring rope is achieved on the land, the installation process is greatly simplified, and the installation efficiency is improved.

    本发明涉及海洋工程技术领域,提供一种用于张力腿浮式风机系泊的高抗拔力螺旋桩及其施工方法,螺旋桩包括:螺旋桩桩身,其上布置螺旋叶片;钻头,设置在所述螺旋桩桩身的底端;系泊桩帽,设置在螺旋桩桩身的顶端,其内部存储系泊用缆绳;传动连接件,安装在系泊桩帽的顶部,与外接动力源连接,为螺旋桩桩身和钻头传递扭矩。根据本发明的方案,本发明中的螺旋桩结构显著提升了锚固基础轴向抗拔能力。本发明无需使用打桩的方法,避免了大型特种装备的使用,钻进的施工过程极大的提高了施工效率,便于规模化应用。本发明将系泊缆绳与系泊桩帽连接在一起,并且存放在桩帽内部,在陆上实现了系泊缆下部的连接,极大的简化了安装流程,提高了安装效率。
