Uplift cast-in-place pile for reinforcing seabed and construction method thereof
The invention discloses an anti-pulling cast-in-place pile for reinforcing a seabed and a construction method of the anti-pulling cast-in-place pile, and belongs to the technical field of underwater infrastructure construction. Comprising a pile body, convex thorns and a first pipeline. The pile body is a cylindrical barrel with openings in the upper and lower ends, and a plurality of extending holes are formed in the side wall of the pile body; the convex thorns are of conical telescopic structures, cavities are formed in the convex thorns, a plurality of water outlet holes are formed in the side walls of the convex thorns, and the convex thorns are fixedly mounted on the extending holes in one-to-one correspondence and can extend out of the pile body or retract into the pile body; the first pipeline is correspondingly connected with the convex thorns, penetrates into the pile body and is used for being connected with the maximum-diameter end of the corresponding convex thorn and the pump machine. The convex thorns penetrate into the seabed around the pile and the side friction resistance of the pile body and the soil body of the seabed around the pile is enhanced by filling, draining and grouting the convex thorns, so that the pulling resistance and the stability of the pile foundation are improved, the anti-scouring capacity and the bearing capacity of the pile foundation are enhanced by grouting, and the construction method is flexible, simple and convenient, and is particularly suitable for the construction environment with the weak seabed foundation.
本发明公开了加固海床的抗拔灌注桩及其施工方法，属于水下基础建设技术领域。包括桩体、凸刺和第一管道。桩体为上下端开口的柱形筒体，其侧壁开设有多个伸出孔；凸刺为锥形伸缩结构且内部设空腔，其侧壁开设多个出水孔，凸刺固定安装在与之一一对应的伸出孔上，凸刺可伸出桩体或收缩至桩体内；第一管道对应连接凸刺，穿入所述桩体内用于连接与之对应的凸刺的最大口径端和泵机。本发明通过向凸刺内充、排水、灌浆等方法使凸刺贯入桩周海床并增强桩体与桩周海床土体的侧摩阻力，由此提高桩基抗拔力和稳定性，并通过灌浆加强了桩基抗冲刷能力与承载力，施工方法灵活简便，尤其适用于海床基础软弱的施工环境。
