Construction method of implanted anchor rod type uplift pile
The invention discloses a construction method of an implanted anchor rod type uplift pile. The method comprises the following steps that firstly, a foundation is drilled to form a pile hole with the reserved depth; secondly, a reinforcement cage is put into the pile hole; thirdly, an anchor rod casing pipe is put into the pile hole, the anchor rod casing pipe is pressed on a hole opening of the pile hole, and the anchor rod casing pipe is inserted into a pile hole bottom ground by a certain depth; fourthly, an anchor rod is inserted into the anchor rod casing pipe, and the anchor rod extends out of the bottom of the anchor rod casing pipe and enters the pile hole bottom ground by a certain depth; fifthly, slurry is injected into the anchor rod casing pipe to form an anchorage segment in the pile hole bottom foundation, and the anchor rod casing pipe and the supporting frame are moved away from the pile hole; and sixthly, the concrete is poured into the pile hole, after concrete final setting, anchor rod tensioning and anchor head locking are carried out, and the uplift pile is finally formed. The formed uplift pile is large in uplift force, the number of uplift piles can be effectively reduced, and the pile length is reduced.
本发明公开植入锚杆型抗拔桩的施工方法，包括以下步骤：1）在地基上钻孔以形成预定深度的桩孔；2）将钢筋笼放入桩孔内；3）将锚杆套管放入桩孔内，并在桩孔的孔口处按压锚杆套管，使得锚杆套管插入桩孔底部地基一定深度；4）在锚杆套管中插入锚杆，锚杆延伸出锚杆套管底部并进入桩孔底部地基一定深度；5）在锚杆套管内注入浆液以在桩孔底部地基内形成锚固段，然后将锚杆套管和支撑架从桩孔上移走；6）在桩孔内灌注混凝土，混凝土终凝后对锚杆张拉及锚头锁定，最终形成抗拔桩。本发明形成的抗拔桩抗拔力大，能够有效减少抗拔桩的数量和减小桩长。
