The invention discloses a recoverable barb pile anchor system which comprises a prefabricated or cast-in-place hollow main pile made of a steel or reinforced concrete material; the prefabricated barb reinforcing body extends outwards from the preset opening position of the side wall through the cavity of the main pile to enter a surrounding rock-soil body to provide bearing force for the pile-anchor structure; wherein the preset opening position of the main pile is locally provided with structure reinforcing and water stopping measures, and reliable connection and water prevention of the barbs and the main pile are achieved; and the force transmission component realizes reliable force transmission among the piles, the anchors and the barbs of the main body. The prefabricated main pile and the barbs can be penetrated and pulled out through special equipment, and therefore the purpose of recycling is achieved. The problems that in engineering practice, a large number of temporarily-acting pile anchors are manufactured according to a permanent structure and cannot be recycled, so that the construction period is long, resources are wasted, and the environment is polluted are solved.
本申请公开了一种可回收倒刺桩锚系统，包括：预制或现浇的中空主桩，为钢制或钢筋混凝土材质；预制的倒刺增强体，通过主桩空腔由侧壁预设开口位置外展进入周围岩土体，为桩锚结构提供承载力；其中主桩的预设开口位置局部有结构加强和止水措施，实现倒刺和主桩的可靠连接及防水；以及传力构件，实现主体的桩、锚与倒刺之间可靠的力的传递。预制主桩和倒刺可通过专门的设备实现贯入和拔除，从而达到回收再利用的目的。本申请解决了工程实践中大量临时作用的桩锚，按照永久结构制作而不可回收，从而导致施工周期长、资源浪费和环境污染的问题。
