The invention discloses a large-size barb pile technology suitable for land or ocean geotechnical engineering. A prefabricated or cast-in-place main pile, a hollow interlayer with the closed bottom and a prefabricated barb reinforcing body are included. And after the open main pile and the interlayer are implemented in place, the barbs are pressed into surrounding rock-soil bodies from the preset opening positions of the side wall of the main pile through the cavity of the interlayer, or after the main pile is drilled, the barbs are implemented firstly, and then main pile concrete is poured. The length of a single barb is slightly smaller than the inner diameter of the main pile, the abduction effect which is close to two times of the diameter of the main pile can be achieved by symmetrically arranging the barbs on the two sides, and enhanced bearing capacity, rigidity and stability are provided for a pile anchor structure. The problems that a conventional large-size pile is large in material consumption and high in cost are effectively solved, after the service mission of a foundation is finished, some components can be detached and recycled, and low carbon and environmental protection are facilitated.
本申请公开了一种适用于陆地或海洋岩土工程的大尺寸倒刺桩技术，包括：预制或现浇的主桩、底部封闭的中空夹层和预制的倒刺增强体。敞口主桩和夹层实施就位后，倒刺通过夹层空腔由主桩侧壁预设开口位置压打入周围岩土体，或者在主桩成孔后，先实施倒刺再浇筑主桩混凝土。单根倒刺的长度略小于主桩内径，双侧对称设置最小可实现接近2倍主桩直径的外展效果，为桩锚结构提供增强的承载力、刚度和稳定性。本申请有效改善了常规大尺寸桩材料消耗大和成本高的问题，在基础服役使命结束后，一些部件还可以拆除回收，有利于低碳环保。
