Accurate cutting construction method for rotary excavating pile
The invention discloses a precise cutting construction method for a rotary excavating pile. The method comprises the steps of pile position lofting, drilling machine in-place, pile casing burying, precise cutting drill bit cutting drilling, precise cutting drill bit lifting and slag discharging, hole measuring and replacement with a bucket tooth drill bit to drill to the designed elevation. A precise cutting drill bit is adopted for carrying out cutting treatment on a waste reinforced concrete pile body, the cutting precision can be effectively improved, hole position deviation is prevented, and meanwhile the waste reinforced concrete pile body can be rapidly cut.
本发明公开了一种旋挖桩精准切削施工方法，包括有桩位放样、钻机就位、埋设护筒、精准切削钻头切削钻进、精准切削钻头提升卸渣、测孔和更换成斗齿钻头钻进至设计标高。本发明采用精准切削钻头对废旧钢筋混凝土桩体进行切削处理，能有效提高切削的精度，防止孔位偏位，同时可快速切削废旧钢筋混凝土桩体。
