Full-casing full-slewing drilling machine hole-forming process
The invention provides a full-casing full-slewing drilling machine hole-forming process. The full-casing full-slewing drilling machine hole-forming process comprises the following technological processes that S1, platform is manufactured and mounted; S2, discharge points is measured; S3, the full-slewing drilling machine is in place; S4, casing pipe is manufactured and mounted; S5, drilling and acceptance inspection are conducted; S6, drilling displacement is conducted; S7, a reinforcing steel bar shed is constructed; S8, a reinforcing steel bar cage and a detection pipe are manufactured and installed; S9, a guide pipe and a hopper are installed; S10, underwater concrete pouring is carried out; S11, pile foundation detection, wherein an ultrasonic detection method is adopted; S12, the casing pipe is cut underwater; and S13, completion and site cleaning are carried out. According to the full-casing full-slewing drilling machine hole-forming process, a common full-slewing drilling machine and a special cantilever platform are combined, so that the hole forming problem of a high-cantilever deepwater anti-impact pile is effectively solved, the construction progress is greatly accelerated, and obvious economic benefits are achieved; the problem that the structure cannot be subjected to excessive vibration is solved, so that the construction process that holes can be formed in the structure only manually is replaced; the problem that no construction operation platform is arranged at the top end of the structure can be solved, and the construction technology of deep water pile foundation hole forming is achieved.
本发明提供一种全套管全回转钻机成孔工艺，包括以下工艺流程：S1：平台制作安装；S2：测量放点；S3：全回转钻机就位；S4：套管制作安装：S5：钻孔并验收；S6：钻孔移位：S7：钢筋棚建设：S8：钢筋笼及检测管的制作与安装；S9：导管及料斗的安装；S10：水下混凝土浇筑；S11：桩基检测，采用超声波检测法；S12：套管水下切割；S13：完工清场。本发明采用普通全回转钻机和特制悬挑平台结合，有效解决了高悬挑深水抗冲桩的成孔难题，大大的提高了施工进度，具有明显的经济效益；解决不能受过大震动的结构，从而代替了只能人工在结构物上成孔的施工工艺；不仅能解决在结构物顶端无施工作业平台的难题，也解决了深水桩基成孔的的施工工艺。
