Implanted socketed pile foundation and construction method
The invention relates to the technical field of ocean engineering, in particular to an implantable socketed pile foundation and a construction method. An implantable socketed pile foundation is suitable for seabed socketed construction and comprises a platform provided with an operation plane and main legs, and the main legs are provided with mounting through holes; the pile casing pile is fixedly arranged in the mounting through hole in a penetrating mode, a guide through hole is formed in the pile casing pile, the end face of one end of the pile casing pile is flush with the operation plane, and the end face of the other end of the pile casing pile goes deep into a seabed covering layer to the top face of bedrock; the at least three micro pile structures are arranged at intervals, the micro pile structures are fixedly arranged in the guide through holes, each micro pile structure comprises a core rod, and the drilling end of each core rod is fixedly arranged in the seabed bed rock so that the seabed bed rock can be connected with the core rods in an anchoring mode. The technical problem to be solved is that when an included angle exists between a pile foundation and the surface of a seabed, a drilling hole is inclined, so that a reinforcement cage cannot be lowered smoothly, and a high-quality concrete core column is difficult to form.
本发明涉及海洋工程技术领域，具体涉及一种植入式嵌岩桩基础及施工方法。一种植入式嵌岩桩基础，适于海床嵌岩施工，包括：平台，设有操作平面和主腿，主腿设有安装通孔；护筒桩，固定穿设于安装通孔内，护筒桩设有导向通孔，护筒桩一端的端面与所述操作平面平齐，另一端的端面深入海床覆盖层直至基岩顶面；至少三个间隔设置的微桩结构，微桩结构固定设于所述导向通孔内，所述微桩结构包括芯杆，芯杆的钻探端固定设于海床基岩内，以使海床基岩与芯杆锚固连接。本发明要解决的技术问题解决了桩基与海床表面存在夹角时，钻孔倾斜导致钢筋笼无法顺利下放，难以形成高质量的混凝土芯柱的问题。
