Construction method for pile hole collapse treatment after installation of cast-in-place pile reinforcement cage
The invention discloses a construction method for pile hole collapse treatment after installation of a cast-in-place pile reinforcement cage, and relates to the technical field of pile hole construction.A percussion drill is used for pressing and damaging the reinforcement cage, the reinforcement cage is disintegrated, and a reinforcement cage residue body and reinforcement cage chippings are obtained; and then a reinforcement cage residue body is taken out through a barrel drill, reinforcement cage chippings are taken out through a residue taking-out barrel, and therefore the reinforcement cage in the collapsed pile hole is taken out. The barrel drill comprises a first drill barrel and a second drill barrel which rotate reversely, so that a first lasso mounted on the first drill barrel and a second lasso mounted on the second drill barrel are wound on the middle portion and the upper portion of a reinforcement cage residue body in the form of opposite rotation directions, the reinforcement cage residue body is hoisted and taken out when the barrel drill is pulled out, the construction success rate is high, and the construction efficiency is improved. And the problem of low efficiency caused by repeated construction is avoided.
本发明公开了一种用于灌注桩钢筋笼安装后桩孔塌孔处理的施工方法，涉及桩孔施工技术领域，通过冲击钻对钢筋笼进行下压、破坏，将钢筋笼解体，得到钢筋笼残渣主体和钢筋笼碎屑，然后利用筒钻将钢筋笼残渣主体取出、利用掏渣筒将钢筋笼碎屑取出，从而取出坍塌桩孔内的钢筋笼。筒钻包括反向转动的第一钻筒和第二钻筒，从而使安装在第一钻筒上的第一套索和安装在第二钻筒上的第二套索以旋向相反的形式缠绕的钢筋笼残渣主体的中部和上部，从而在拔出筒钻时将钢筋笼残渣主体吊装取出，施工成功率高，避免了重复施工导致效率低下的问题。
