Construction method of rock-socketed occlusive pile in rock-filled stratum
The invention discloses a construction method of a rock-socketed occlusive pile in a rock-filled stratum, belongs to the technical field of foundation pit enclosure construction, and solves the problem of low construction efficiency of the occlusive pile due to the high complexity of an underground stratum and the limitation of construction technology. A site requiring construction is subjected tostratum replacement, the construction efficiency of the occlusive pile is improved, a pile grinding machine is not used any longer, firstly, the bottom end of a protective tube is pressed into the stratum with the help of a pressurizer, a rotary drilling rig is used for drilling and taking soil with a barrel drill, when the barrel drill drills 3-6m in the stratum, the protective tube is pressed again with the help of the pressurizer, and this operation is repeated until the protective tube reaches the specified depth; a casing is not needed to be in advance, an all casing drill is not neededto be invested, the protective tube is just embedded, the rotary drilling drill is adopted to form a hole, the construction efficiency of the occlusive pile is improved greatly, and the construction cost is reduced.
填石地层嵌岩咬合桩施工方法，属于基坑围护施工技术领域，解决了由于地下地层的高度复杂性和施工工艺的限制，咬合桩施工效率低的问题，对所需施工场地进行地层换填，提高咬合桩的施工效率，不再使用磨桩机，先将护筒底端借助加压器压入进地层，采用旋挖钻机以筒钻进行钻孔取土，每当筒钻向地层钻孔深度3‑6m时，则再次借助加压器压入护筒，循环此操作，直至护筒达到指定深度，无需套管超前，无需投入全套管钻机，只需埋设护筒，采用旋挖钻机成孔，大大提高了咬合桩的施工效率，降低了施工成本。
