Recyclable temporary anti-floating pile for construction stage and construction method thereof
The invention discloses a recoverable temporary anti-floating pile for a construction stage. The recoverable temporary anti-floating pile comprises a pile body, a reinforcement cage and a load bearing device, the reinforcement cage is arranged in the pile body, a first construction foundation is arranged at the top of the reinforcement cage, and a cushion layer is arranged below the first construction foundation; the load bearing device is arranged above the reinforcement cage, and the pile body and the reinforcement cage are both connected with the load bearing device; the reinforcement cage comprises a plurality of sets of recycling main reinforcements, isolation corrugated pipes and anchoring main reinforcements, the recycling main reinforcements are connected with the anchoring main reinforcements, the isolation corrugated pipes are arranged on the outer sides of the recycling main reinforcements in a sleeving mode, and the multiple sets of recycling main reinforcements, the isolation corrugated pipes and the anchoring main reinforcements are arranged to be a cage body of a cylindrical structure. The anti-floating piles are constructed according to the most unfavorable construction conditions, underground water does not need to be pumped and drained during construction, recycled steel bars of the anti-floating piles can be recycled when a constructed main body structure can resist underground water buoyancy, after the recycled steel bars are removed, remaining pile bodies and a foundation form a composite foundation to jointly share upper loads, the design of a foundation bottom plate is optimized, and the construction cost is reduced. And the engineering economy is improved.
本发明公开了一种施工阶段用可回收的临时抗浮桩，包括：桩体、钢筋笼和承荷装置；钢筋笼设置在桩体内，钢筋笼顶部设置有第一施工基础，在第一施工基础的下方设置有垫层；承荷装置设置在钢筋笼的上方，且桩体和钢筋笼均与承荷装置相连接；钢筋笼包括多组回收主筋、隔离波纹管和锚固主筋，回收主筋与锚固主筋相连接，隔离波纹管套设在回收主筋的外侧，多组回收主筋、隔离波纹管和锚固主筋设置为圆柱形结构笼体。按照施工最不利情况施工抗浮桩，施工时不需要将地下水抽排，抗浮桩的回收钢筋能够在已施工的主体结构能够抵抗地下水浮力时进行回收，拆除回收钢筋后，遗留桩体与基础形成复合地基共同分担上部荷载，优化基础底板设计，提高工程经济性。
