Telescopic friction wing pile foundation and construction method
The invention relates to the technical field of offshore wind power, in particular to a telescopic friction wing pile foundation and a construction method. A telescopic friction wing pile foundation comprises a pipe pile, the pipe pile is suitable for being arranged on the seabed, an opening is formed in the pile wall, sinking into a soil layer below the seabed plane, of the pipe pile, a grouting channel is formed in the pipe pile, and high-pressure gas is suitable for being introduced into the grouting channel; and the telescopic wing assembly is arranged in the opening, the grouting channel is connected with the telescopic wing assembly in a penetrating mode, and the telescopic wing assembly is unfolded in the direction away from the pipe pile wall under the action of high-pressure gas. According to the telescopic friction wing pile foundation and the construction method, the problems that supporting wings are arranged on the side wall of a single pile foundation, but the supporting wings are fixed before sinking, the transportation difficulty of the single pile foundation with wings is high, and the resistance is too large in the sinking process are solved, and therefore the telescopic friction wing pile foundation and the construction method are provided.
本发明涉及海上风电技术领域，具体涉及一种伸缩式摩擦翼桩基础及施工方法。一种伸缩式摩擦翼桩基础，包括：管桩，所述管桩适于设于海底，所述管桩沉入海底平面下方土层的桩壁上设有开口，所述管桩内设有注浆通道，所述注浆通道内适于通入高压气体；伸缩翼组件，所述伸缩翼组件设在开口内，所述注浆通道与伸缩翼组件贯通连接，所述伸缩翼组件在高压气体作用下朝向背离管桩桩壁的方向展开。本发明解决在单桩基础的侧壁上设置支翼，但却面临着在下沉前已经固定好支翼，存在带翼单桩基础运输难度高、在下沉过程中阻力过大的问题，从而提供一种伸缩式摩擦翼桩基础及施工方法。
