Casing Rotator

ʻO ka rotator roting kahi ʻano drill hou me ka hoʻopili ʻana o ka mana piha hydraulic a me ka lawe ʻana, a me ka kaohi o ka mīkini, ka mana a me ka wai. He mea hou, ʻenehana a pilikino a me ka ʻenehanaʻeli ʻeli kūpono. I nā makahiki i hala aku nei, ua ʻāpono ʻia ia i nā papahana e like me ke kūkulu ʻana o ke alaloa o ke kūlanakauhale, ka puʻupuʻu o ka pā hohonu hohonu, ka hoʻomaʻemaʻe ʻana o nā puʻu ʻōpala (nā wahi ālai ʻia), ke kaʻaahi wikiwiki, ke alanui a me ke alahaka, a me nā paina kūkulu kūlanakauhale. a me ka hoʻoikaika ʻana o ka waihona waipuna.
ʻO ka noiʻi kūleʻa o kēia ʻano hana hou i ʻike ʻia ka hiki no ka poʻe hana kūkulu e hana i ke kūkulu ʻana i ka paipu casing, pile hoʻoneʻe, a me ka paia mau o ka honua, a me nā mea hiki i ka paipu-jacking a me ka tunnel pale e hele i loko o ka nā kumu paila like ʻole me nā mea keakea ʻole, ke hemo ʻole nā ​​mea ālai, e like me ka hana ʻana o ka ʻiliʻili a me ka pōhaku, ke ana ʻana, ka stratum mānoanoa nui, ka hoʻokumu ʻana i nā ʻāpana puʻupuʻu a me nā paʻa paʻa paʻa paʻa paʻa kila.
Ua hoʻopau maikaʻi ke ʻano hana o ka rotate casing rotation ma mua o 5000 mau papahana ma nā wahi o Singapore, Japan, Hongkong District, Shanghai, Hangzhou, Beijing a me Tianjin. He ʻoi aku ka nui o kāna hana i ka wā e hiki mai ana ke kūkulu kūlanakauhale a me nā kahua kūkulu kahua ʻoi aʻe.

 Ka mālama ʻana o ka paia i ka paia o ka waihona wai.
(2) Nā ʻeli ʻana, nā pōhaku a me nā ana karst
 ʻAe ʻia e alakaʻi i ke kūkulu ʻana o nā paila kahua ma nā ʻāina mauna me nā ʻiliʻili a me nā pōhaku.
 ʻAe ʻia e alakaʻi i ka hana a hoʻolei i nā kumu o ke kahua i ka hoʻokumu ʻia ʻana o ka wikiwiki a me ka hoʻopili ʻana i ka stratum a i ʻole ka hoʻopihapiha hoʻopihapiha.
 Hana i ka wili pōhaku i ka stratum pōhaku, hoʻolei i ka paepae kahua.
(3) Holoi i nā ālai honua
 I ka wā o ke kūkulu kūlanakauhale a me ke kūkulu hou ʻana i ke alahaka, hiki ke hoʻomaʻemaʻe pololei ʻia nā paina e like me ka paila paʻa paʻa paʻa kila, nā paila paipu kila, nā puʻupuʻu H, ka paila pc a me nā paina wahie, a hoʻolei i ka paepae kahua ma kahi.
(4) ʻoki i ka stratum pōhaku
 E alakaʻi i ka ʻeli pōhaku i hoʻopaʻa ʻia i nā paila o nā mea hoʻolei.
 ʻEli puka-ma luna o ka moena pōhaku (nā ʻau a me nā puka ea)
(5) Ka ʻeli hohonu ʻana
 Hana i ka hoʻoheheʻe ʻana i ka wahi a i ʻole ka paipu kila e hoʻokomo nei no ka hoʻomaikaʻi hohonu hohonu.
 E ʻeli i nā luawai hohonu no ka hana kūkulu i nā kūkulu o ka waihona wai a me ke tunnel.
