Pressure-type post-inserted composite rib uplift pile for constructional engineering and construction method of pressure-type post-inserted composite rib uplift pile
The invention discloses a constructional engineering pressure type post-inserted composite rib uplift pile and a construction method of the constructional engineering pressure type post-inserted composite rib uplift pile, and belongs to the technical field of construction piles.The constructional engineering pressure type post-inserted composite rib uplift pile comprises an uplift pile body, a conical head guide cap, a bearing plate, a limiting plate, a steel pipe bearing body, a slow-bonding steel strand, a prestressed steel strand self-locking device and a prestressed steel bar are inserted behind the composite bar; according to the scheme, long spiral hole forming is adopted, concrete is poured firstly, then composite ribs are inserted, the pile body quality of the uplift pile body is guaranteed, and the bearing capacity of the uplift pile body is guaranteed. The problem of water leakage caused by improper treatment of a raft tensioning end and a steel strand tensioning end is solved by arranging the prestressed reinforcements on the upper portions of the composite reinforcements, and the problem that the reinforcements cannot meet the anti-seismic effect under the anti-floating effect is better solved by arranging the slow-bonding steel strands on the lower portions of the composite reinforcements. The problem that the stress defect of a single material is eliminated due to the fact that different materials are matched in different stress areas under the action force of different working conditions of prestressed reinforcements and prestressed steel strands is solved.
本发明公开了建筑桩技术领域的一种建筑工程压力型后插复合筋抗拔桩及其施工方法，包括抗拔桩体，所述抗拔桩体的内部植入有复合筋，所述复合筋后插锥头导向帽、承压板、限位板、钢管承载体、缓粘结钢绞线、预应力钢绞线自锁装置和预应力钢筋；本方案采用长螺旋成孔先浇筑混凝土再后插复合筋，保证抗拔桩体的桩身质量，抗拔桩体的承载力得到保障。通过复合筋上部配置预应力钢筋消除筏板张拉端、钢绞线张拉端处理不当造成的漏水问题，下部配置缓粘结钢绞线更好的解决抗浮作用下钢筋无法满足抗震效果，有效减少抗浮锚杆设计时体量大，解决预应力钢筋和预应力钢绞线在不同工况作用力下，不同受力区域配不同材料，消除单一材料的受力缺陷问题。
