Construction method of self-propelled pile casing arranged on rotary drilling rig
The invention belongs to the technical field of pile casing burying, and discloses a construction method of a self-propelled pile casing arranged on a rotary drilling rig. The method comprises the following steps: S1, machining and welding a steel plate with sigma larger than 30mm into a circular pipe cap, and welding a steel plate with sigma 2 larger than 25mm into a pile casing; s2, after the pipe cap is clamped into the pile casing based on S1, a pin is transversely inserted, and the pipe cap and the pile casing are connected into a whole; s3, connecting a drill rod of the rotary drilling rig with the pipe cap in a pin inserting manner, starting the drilling rig, and spinning the pile casing according to a measuring point until the first section is exposed by 30cm in soil; s4, the transverse pin is pulled out, the pipe cap is connected with the second section of pile casing, the position is adjusted so that the upper-lower concave-convex accurate butt joint can be achieved, an H-shaped plug pin is inserted, and a fixing rod is vertically inserted; s5, after the butt joint of the second section of pile casing is completed, the steel pressing pile casing is discontinuously rotated; and S6, if the pile casing needs to be lengthened and pressed in according to geological requirements, the steps S3-S5 are intermittently repeated until completion. And compared with the mode that holes are punched in soil, the pile casing is placed, and then the soil is compacted, soil loosening can be avoided, and the stability of the pile casing can be improved.
本发明属于护筒埋设技术领域，且公开了一种旋挖钻机配置的自进式护筒的施工方法，包括以下步骤；S1.采用σ＞30mm钢板加工焊接成圆形管帽，采用σ2＞25mm钢板焊接成护筒；S2.基于S1将管帽卡入护筒后采用横向插入销钉，将管帽与护筒连接成一个整体；S3.将旋挖钻机钻杆与管帽销插连结，启动钻机，按测量点旋压护筒至首节入土外露30cm；S4.抽出横向销钉，将管帽与第二节护筒连结，调整位置使上下凹凸准确对接，插入H型插销，并竖向插入固定杆；S5.第二节护筒对接完成后，断续旋转压钢护筒；S6.若根据地质要求，需要加长压入护筒，断续重复S3‑S5步骤直至完成。相比在土中打孔将护筒放置再夯实土壤的方式，能够避免土壤的松动提高护筒的稳定性。
