Construction method of novel slope protection pile
The invention discloses a construction method of a novel slope protection pile. The construction method comprises the steps of paying-off positioning, drilling machine in-place and hole forming, re-drilling and hole forming, slope protection pile concrete pouring and reversely-inserted reinforcement cage pile forming. The construction method has the beneficial effects that a rotary drilling rig and a long spiral drilling rig are mechanically combined, the advantages of the rotary drilling rig are utilized, the influence of underground obstacles such as underground anchor rod bodies is effectively eliminated, and the construction potential safety hazard caused by the long spiral drilling rig encountering steel strands is avoided; by combining the construction process of the long spiral center pressure pouring reverse insertion reinforcement cage, a small construction site is occupied, concrete construction loss caused by pile casings and underwater pouring is reduced, and the site and materials are saved; according to the construction process of the long spiral center pressure grouting reverse insertion reinforcement cage, the pile forming quality is good; through rotary hole digging, the re-hole-forming speed of a long spiral is increased, concrete pouring is continuous, construction is coherent, and the construction speed is high; and the construction method has a wide application market in narrow and limited construction sites with a plurality of underground anchor rods and other obstacles close to municipal roads.
本发明公开了一种新型护坡桩的施工工法，包括放线定位、钻机就位及成孔、复钻成孔、护坡桩混凝土灌注、反插钢筋笼成桩。本发明的有益效果是：将旋挖钻机与长螺旋钻机两种机械结合，利用了旋挖钻机优点，有效地消除了地下锚杆杆体等地下障碍物的影响，避免长螺旋钻机遇到钢绞线带来的施工安全隐患；结合长螺旋中心压灌反插钢筋笼的施工工艺，占用较小的施工场地，减少护筒和水下灌注带来的混凝土施工损耗，节约场地和材料；长螺旋中心压灌反插钢筋笼的施工工艺，成桩质量佳；通过旋挖引孔，长螺旋再成孔速度提高，且混凝土浇筑连续，施工连贯，施工速度快；在临近市政道路、有多道地下锚杆等障碍物，且施工狭小有限的场地，具有广阔的应用市场。
