Deep anchor rod ground barrier device for treating stratum prone to collapse and ground barrier hole forming method
The invention relates to the technical field of pile foundation construction, in particular to a deep anchor rod ground barrier device for processing an easy-to-collapse stratum, which comprises a power head, and a pile casing driver is arranged below the power head, a ground barrier hole forming method for processing a deep anchor rod for processing the easy-to-collapse stratum comprises the following steps: S1, leveling a construction site and measuring a pile placement position; the rotary drilling rig has the beneficial effects that the pile casing driver is arranged on the rotary drilling rig, so that construction of the rotary drilling rig can be achieved, the middle pile casing can be driven to follow up and put down in a segmented mode, the rotary drilling rig is effectively suitable for bored pile hole forming of an easy-to-collapse stratum, hole collapse is prevented, and the construction efficiency is improved. And the diamond drill teeth additionally arranged at the end of the first pile casing can be used for annularly cutting a deep anchor rod ground barrier, and compared with a conventional full-casing full-slewing drilling machine, required construction equipment is small in size, high in equipment utilization rate, high in hole forming speed and low in cost.
本发明涉及一种处理易坍塌地层的深层锚杆地障装置，涉及桩基施工技术领域，包括动力头，所述动力头的下方设置有护筒驱动器，一种处理易坍塌地层的深层锚杆的地障成孔方法，包括以下步骤：S1、平整施工场地及测放桩位；S2、定制端部带有金刚石钻齿的3m的首节钢护筒和中间3m标准的首节钢护筒，有益效果：通过在旋挖钻机上设置护筒驱动器，既能实现旋挖钻的施工，又能通过驱动中间节护筒的分节跟进下放，有效地适应易坍塌地层的钻孔桩成孔，防止塌孔，又能通过第一节护筒端头增设的金刚石钻齿环切深层锚杆地障，所需的施工设备相对常规全套管全回转钻机体积小，设备利用率高，成孔速度快，且成本低。
