The invention relates to a post-tensioned prestressed large-pulling-resistance pile formed by deeply stirring and implanting cement into tubular piles, which is characterized in that a cylindrical cement-soil pile body 1 with the designed depth L and the diameter D is formed by stirring through a cement powerful stirring pile machine, prefabricated reinforced concrete tubular piles 2 are implanted in sections, and steel strands 3 are arranged in each section of tubular pile; when an underground structure bearing platform 21 is poured, pile head pre-embedded anchor bars 11 of the prefabricated reinforced concrete pipe piles 2 are anchored into the bearing platform, meanwhile, steel base plates 15 and anchoring parts 9 of the steel strands 3 are pre-embedded, and notches 17 are reserved in the positions of the steel base plates 15 and the anchoring parts 9; and after prestress is applied to the steel strand 3 and the steel strand 3 is locked, concrete 12 is poured into the cavity of the pipe pile, cement paste pressure grouting is conducted on the cavity of the whole pipe pile from the pipe bottom to the pipe top through the pre-buried grouting pipe 13, and construction of the post-tensioning prestress large-pulling-resistance pile formed by embedding the cement into the pipe pile in a deep stirring mode is completed. The novel anti-floating pile has the advantages of being high in bearing capacity, easy and convenient to construct, low in manufacturing cost, small in influence on the environment, easy to construct and operate and the like.
本发明是一种水泥深搅植入管桩后张预应力大抗拔力桩，采用水泥强力搅拌桩机搅拌形成设计深度L、直径为D的圆柱状水泥土桩体1后，分节植入预制钢筋混凝土管桩2，各节管桩内设有钢绞线3；地下结构承台21浇筑时将预制钢筋混凝土管桩2的桩头预埋锚筋11锚入承台内，同时将钢绞线3的钢垫板15和锚固件9预埋，并在钢垫板15和锚固件9处预留缺口17；对钢绞线3施加预应力并锁定后，往管桩空腔内浇灌混凝土12，通过预埋的注浆管13对整根管桩空腔从管底进行水泥浆压力注浆至管顶，完成水泥深搅植入管桩后张预应力大抗拔力桩的施工；这种新型的抗浮桩具有承载力高、施工简便、造价低廉、对环境影响小且施工操作简单等优点。
