1. Olelo mua
ʻO ka Rotary drilling rig he mīkini hana kūpono no nā hana wili i ke kūkulu ʻana i ka ʻenekinia kumu. I kēia mau makahiki i hala iho nei, ua lilo ia i mea ikaika nui i ke kūkulu ʻana i ke kahua paʻa i ke kūkulu ʻana i ke alahaka ma Kina. Me nā mea hana wili like ʻole, kūpono ka wili wiliwili no nā hana wili ma kahi maloʻo (pilipili pōkole), pulu (rotary bucket) a me nā papa pōhaku (core drill). Loaʻa iā ia nā hiʻohiʻona o ka mana kiʻekiʻe i hoʻokomo ʻia, kiʻekiʻe kiʻekiʻe torque pukana, nui axial kaomi, maʻalahi maneuverability, kiʻekiʻe kūkulu pono a me ka multifunctionality. ʻO ka mana i helu ʻia o ka rotary drilling rig ma ke ʻano he 125-450kW, ʻo ka mana hoʻopuka mana ʻo 120-400kN•m, hiki i ke anawaena puka kiʻekiʻe ke hiki i 1.5-4m, a ʻo ka hohonu o ka lua he 60-90m, hiki ke hoʻokō i nā koi o nā ʻano hana kumu nui.
I ke kūkulu ʻia ʻana o ke alahaka ma nā wahi paʻakikī, ʻo ke ʻano hana maʻamau i hoʻohana ʻia i ke ʻano o ka hoʻokumu ʻana i nā kumulāʻau he manual excavation pile method and impact drilling method. Hoʻopau mālie ʻia ke ʻano hana ʻeli lima ma muli o ka lōʻihi o ke kūkulu ʻia ʻana o nā kumu puʻu, nā ʻenehana kahiko, a me ka pono o nā hana hoʻoheheʻe ʻana, kahi mea e pilikia ai a me nā pōʻino; Aia kekahi mau pilikia me ka hoʻohana ʻana i nā ʻauwaʻa hopena no ke kūkulu ʻana, ʻike nui ʻia i ka wikiwiki o ka wili ʻana i ka hopena i nā papa pōhaku paʻakikī, a me ke ʻano o ka ʻole ʻana i ka lā. Inā hoʻomohala maikaʻi ʻia ka karst geological, hana pinepine ʻia ka wili ʻana. I ka wā e puka mai ai ka wili ʻana, ʻo ke kūkulu ʻia ʻana o ka puʻu wili ʻia he 1-3 mahina, a ʻoi aku paha. ʻO ka hoʻohana ʻana i nā rigs rotary drilling no ke kūkulu ʻana i ke kumu pile ʻaʻole wale ka hoʻomaikaʻi nui ʻana i ka wikiwiki o ke kūkulu ʻana a hōʻemi i nā kumukūʻai kūkulu, akā hōʻike pū kekahi i ke kiʻekiʻe o ka maikaʻi o ke kūkulu ʻana.
2. Nā hiʻohiʻona o nā ʻano hana
2.1 ʻO ka wikiwiki o ka puka ʻana o ka pore
Hoʻolālā ʻia ka hoʻonohonoho niho a me ke ʻano o ka pahu drill core pōhaku o ka rotary drilling rig ma muli o ke kumumanaʻo o ka ʻāpana pōhaku. Hiki iā ia ke wili pololei i loko o ka papa pōhaku, e hopena i ka wikiwiki o ka wili ʻana a me ka hoʻomaikaʻi maikaʻi ʻana i ke kūkulu ʻana.
2.2 Nā pōmaikaʻi maikaʻi loa i ka mana maikaʻi
Hoʻokomo pinepine ʻia nā rig drilling Rotary me kahi pahu puka ma kahi o 2 mika (hiki ke hoʻonui ʻia inā mānoanoa ka lepo backfill ma ka lua), a hiki i ka rig ponoʻī ke hoʻokomo i ka pahu, hiki ke hōʻemi i ka hopena o ka lepo backfill ma ka lua ma ka puʻu wili ʻia; Hoʻohana ka rotary drilling rig i ke kaʻina hana hoʻoheheʻe ʻana i lalo o ka wai oʻo, hiki ke pale i nā hopena ʻino o ka hāʻule ʻana o ka lepo mai ka lua a me ka sediment i hana ʻia i ka wā o ka ninini ʻana; ʻO ka Rotary drilling rig kahi mīkini hana hoʻokumu paʻa e hoʻohui i ka ʻepekema a me ka ʻenehana holomua hou. I ka wā o ka wili ʻana, he kiʻekiʻe ka pololei o ka verticality, ka nānā ʻana i ka papa pōhaku ma lalo o ka lua, a me ka mana o ka lōʻihi o ka puʻu. I ka manawa like, ma muli o ka liʻiliʻi o ka sediment ma lalo o ka lua, ua maʻalahi ka hoʻomaʻemaʻe ʻana i ka lua, no laila ua paʻa pono ka maikaʻi o ka hoʻokumu ʻana o ka waihona.
2.3 Hiki ke hoʻololi i ka hoʻokumu ʻana o ka honua
Hoʻokomo ʻia ka rotary drilling rig me nā ʻāpana drill like ʻole, hiki ke hoʻohana ʻia no nā kūlana geological like ʻole e like me ke one one, ka lepo lepo, gravel, rock layers, etc., me ka ʻole o ka palena ʻāina.
2.4 ʻO ka neʻe ʻana a me ka mana ikaika
Hoʻohana ka chassis o ka rotary drilling rig i kahi chassis excavator crawler, hiki ke hele ma kāna iho. Eia kekahi, hiki i nā rigs drilling rotary ke hana kūʻokoʻa, loaʻa ka neʻe ikaika, hoʻololi i ka ʻāina paʻakikī, a ʻaʻole koi i nā mea kōkua no ka hoʻonohonoho ʻana a me ka wehe ʻana. Noho lākou i kahi liʻiliʻi a hiki ke hana ʻia i nā paia.
2.5 Ka palekana a me ka maʻemaʻe o ke kahua kūkulu
Hiki i ka rotary drilling rig ke hana i loko o nā ʻano pōhaku me ka ʻole o ka lepo, ʻaʻole ia e hōʻemi wale i ka pau ʻole o nā kumu wai akā pale pū kekahi i ka haumia o ke kaiapuni a puni i kumu ʻia e ka lepo. No laila, maʻemaʻe ke kahua kūkulu o ka rotary drilling rig a hoʻohaumia liʻiliʻi i ke kaiapuni.
3. Ka laulā o ka noi
He kūpono kēia ʻano hana no ka ʻeli ʻana i nā puʻu me nā mīkini wiliwili rotary ma nā ʻano pōhaku haʻahaʻa a palupalu me ka maikaʻi o ka pōhaku paʻakikī.
4. Kaʻina hana
4.1 Nā Kumu Hoʻolālā
Ma muli o ke kumu hana o ka rotary drilling rig drilling, i hui pū ʻia me nā waiwai mechanical o nā pōhaku a me ke kumumanaʻo kumu o ka ʻāpana pōhaku e ka rotary drilling rig, ua wili ʻia nā puʻu hoʻāʻo ma nā ʻano limestone maʻalahi me ka pōhaku paʻakikī. ʻO nā ʻāpana ʻenehana kūpono a me nā hōʻailona hoʻokele waiwai o nā kaʻina hana wili like ʻole i hoʻohana ʻia e ka rotary drilling rig i kālai ʻia i ka helu helu. Ma o ka hoʻohālikelike ʻenehana a me ka hoʻokele waiwai a me ka nānā ʻana, ua hoʻoholo hope ʻia ke ʻano hana o ka rotary drilling rig wili puʻu ma nā ʻano pōhaku lime me ka pōhaku paʻakikī.
4.2 Ke kumu o ka ʻenehana wili no ka rig wili ʻana i nā pōhaku
Ma ka hoʻolako ʻana i ka rotary drilling rig me nā ʻano like ʻole o ka drill bits e hana i ka hoʻonui ʻia ʻana o ka lua ma luna o nā papa pōhaku paʻakikī, ua kūkulu ʻia kahi ʻili manuahi ma lalo o ka lua no ka rotary drilling rig drill bit, e hoʻomaikaʻi ana i ka hiki ke komo i ka pōhaku o ka rotary drilling. rig a hiki i ka loaʻa ʻana o ke komo ʻana i ka pōhaku ʻoiai e mālama ana i nā kumukūʻai kūkulu.
