ʻO ka Rotary drilling rig kahi ʻano mīkini hana kūpono no ka hana ʻana i ka lua i ke kūkulu ʻana i ka ʻenehana kumu. He mea kūpono ia no ke kūkulu ʻana i ke one, ka pālolo, ka lepo lepo a me nā papa lepo ʻē aʻe, a ua hoʻohana nui ʻia i ke kūkulu ʻana i nā kumu like ʻole e like me nā puʻu i hoʻolei ʻia, nā paia diaphragm, a me ka hoʻoikaika ʻana i ke kumu. ʻO ka mana helu o ka rotary drilling rig ma ke ʻano he 117 ~ 450KW, ʻo ka mana puka mana he 45 ~ 600kN · m, hiki ke anawaena puka kiʻekiʻe i 1 ~ 4m, a ʻo ka hohonu o ka lua he 15 ~ 150m, hiki ke hoʻokō i nā koi o ʻano hana kumu nui-nui.
Hoʻohana maʻamau ʻo Rotary drilling rig i ka hydraulic crawler telescopic chassis, hoʻokiʻekiʻe ponoʻī a pae ʻana i foldable mast, telescopic kelly bar, me ka ʻike perpendicularity a me ka hoʻoponopono ʻana, hōʻike kikohoʻe hohonu lua, etc. . Maʻalahi a ʻoluʻolu e hana.
Hiki ke hoʻohana ʻia ka winch nui a me ka winch kōkua i nā pono o nā kūlana like ʻole ma ke kahua kūkulu. Hoʻohui pū ʻia me nā mea hana wili like ʻole, kūpono ka rig drilling rotary no ka maloʻo (short auger) a i ʻole pulu (rotary bucket) a me ka hoʻokumu pōhaku (core barrel) hana hole. Hiki ke hoʻolako pū ʻia me ka auger lōʻihi, hopu i ka paia diaphragm, vibrating pile hammer, etc. Hoʻohana nui ʻia ia i ke kūkulu ʻana i ke kaona, ke alahaka alanui, nā hale ʻoihana a me nā hale kīwila, ka paia diaphragm ma lalo o ka honua, ka mālama ʻana i ka wai, ka pale ʻana a me ka pale slope a me nā kūkulu kumu ʻē aʻe.
Hoʻohana ʻia i ka rig wili liʻiliʻi:
(1) Nā puʻu pale pali o nā hale like ʻole;
(2) He ʻāpana o nā puʻu paʻa ukana o ka hale;
(3) ʻO nā puʻu like ʻole me ke anawaena o ka liʻiliʻi ma mua o 1m no nā hana kaona no ka hoʻoponopono hou ʻana i ke kūlanakauhale;
(4) Pile no nā kumu ʻē aʻe.
