Rotary excavating all-casing drilling, sinking and pulling integrated construction method for deep and thick easily-collapsed cast-in-place pile
The invention relates to the technical field of cast-in-place pile construction, and discloses a deep easily-collapsed hole cast-in-place pile rotary excavating all-casing drilling, sinking and pulling integrated construction method which comprises the following construction steps that (1) the pile position for construction is determined; (2) the power head drives the driving cylinder through the connecting cylinder to drill the casing pipe towards the pile position, and soil is taken into the casing pipe through the drilling tool; (3) concrete is poured into the pile hole through the guide pipe; (4) the orifice sleeve pulling and clamping mechanism is arranged on the sleeve in a sleeving mode, and a power head pulls out the sleeve through a driving cylinder; the rotary drilling rig outputs torque and pressure to the casing pipe through the power head in cooperation with the connecting cylinder and the driving cylinder, so that the casing pipe drills and sinks to the set depth at the pile position through the cylinder shoe, soil is taken into the casing pipe through the drilling tool, and a pile hole is formed in the casing pipe; and after concrete pouring of the pile hole is completed, the power head pulls out the casing pipe through the driving cylinder again, according to the construction method, drilling, sinking and pulling of the casing pipe are integrally completed through the rotary drilling rig, and the problems that the construction procedure is complex, and the drilling efficiency is low are solved.
本发明涉及灌注桩施工的技术领域，公开了深厚易塌孔灌注桩旋挖全套管钻、沉、拔一体施工方法，包括如下施工步骤：1)、确定施工的桩位；2)、动力头通过连接筒驱动驱动筒将套管往桩位钻进，通过钻具往套管内取土；3)、通过导管往桩孔内灌注混凝土；4)、将孔口套管起拔夹持机构套设在套管上，动力头通过驱动筒将套管拔出；旋挖钻机通过动力头配合连接筒以及驱动筒向套管输出扭矩以及压力，使得套管通过筒靴在桩位钻沉至设定深度，通过钻具往套管内取土，使套管内形成桩孔；当完成桩孔完成混凝土浇筑后，动力头再次通过驱动筒将套管拔出，该施工方法将套管钻、沉、拔一体通过旋挖钻机完成，解决了施工工序较复杂，且钻进效率低的问题。
