Novel secant pile forming construction technology
The invention discloses a novel secant pile forming construction technology, and relates to the technical field of secant pile forming construction.The novel secant pile forming construction technology comprises the steps that firstly, holes are drilled in a ground base layer according to the fixed interval sequence to form continuous hole positions with the secant width, so that holes are obtained, and the holes are composed of A1, B1, A2, B2 and A3; secondly, locking pipes are placed in the A1 and the A3, the outer diameter of each locking pipe is the same as the pile forming diameter, the bottom of each locking pipe is flush with the bottom of the hole, and each locking pipe is a cross plate steel pipe; according to the novel secant pile forming construction technology, the pile A and the pile B are obtained, the pile A does not need to be cut during construction of the pile B, so that super-delayed coagulation concrete does not need to be adopted for the pile A, during reinforced concrete construction of the pile B, the pile A is already coagulated, the quality of the pile B is not affected by the pile A, the requirements of pile forming mechanical equipment are reduced, the construction period is shortened, the manufacturing cost is saved, and only the two locking pipes need to be inserted and pulled in a reciprocating mode for use; and the construction is more convenient.
本发明公开了一种新型咬合桩成桩施工工艺，涉及咬合桩成桩施工技术领域，步骤一：以固定间距顺序在地面基层上钻孔以形成具备咬合宽度的连续孔位，从而获得孔洞，孔洞由A1、B1、A2、B2、A3构成；步骤二：在A1与A3内部均放入锁口管，锁口管外径与成桩直径相同，管底与孔洞孔底齐平，锁口管采用十字板钢管；该新型咬合桩成桩施工工艺，获得A桩与B桩，使得B桩施工时无需切割A桩，因此A桩无需采用超缓凝混凝土，B桩钢筋混凝土施工时，A桩已完成凝结，B桩质量不会受A桩影响，降低成桩机械设备要求，缩短工期，节约造价，只需对两根锁口管往复进行插拔使用，使得施工较为方便。
