Large-section anchoring pile construction method under landslide mass condition
The invention discloses a large-section anchor pile construction method under a landslide mass condition, which comprises the following steps of: determining a pile body area of an anchor pile to be constructed on a landslide mass; a plurality of fender post holes are evenly formed in the periphery of the pile body area of the anchoring pile in the circumferential direction, and reinforced concrete is poured into all the fender post holes to form a plurality of fender posts arranged on the periphery of the pile body area of the anchoring pile; a rotary drilling coring and pore-forming method is adopted to perform multiple times of coring and pore-forming on the pile body area of the anchoring pile, so that an anchoring pile hole is formed in the pile body area of the anchoring pile; and after steel bars and sounding pipes are placed in the anchoring pile holes, concrete pouring is carried out to form the anchoring piles. The method has the beneficial effects that the hole wall of the anchoring pile hole is protected by the fender post, so that the hole wall of the anchoring pile hole is high in stability and not prone to collapse, the safety of operators in the hole is improved, meanwhile, measures such as anchor rod driving, net hanging and guniting, formwork pouring and concrete filling are not needed, the construction efficiency is effectively improved, and the construction cost is reduced. And a landslide renovation project can be quickly completed.
本发明公开了一种滑坡体条件下大截面锚固桩施工方法，包括确定滑坡体上待施工的锚固桩的桩体区域，在锚固桩的桩体区域的外围沿周向均匀开设若干个围护桩孔、并在各个围护桩孔内均浇筑钢筋混凝土形成布置于锚固桩的桩体区域的外围的若干围护桩；采用旋挖钻取芯成孔方法对锚固桩的桩体区域进行多次取芯成孔，使锚固桩的桩体区域形成锚固桩孔；在锚固桩孔内放入钢筋及声测管后进行混凝土浇筑形成锚固桩。本发明的有益效果是：由于锚固桩孔的孔壁受到围护桩的防护，因此锚固桩孔的孔壁稳定性较高，不易垮塌，提高了孔内作业人员安全性，同时，不需要通过打设锚杆、挂网喷浆、支模浇筑混凝土填塞等措施，有效提升施工效率，可快速完成滑坡整治工程。
