He hanauna hou o na wili wili

Loaʻa i nā mea hana ka hana paʻa, ka hana maʻalahi, ka neʻe maikaʻi, ka hana ʻāpana piha, ka hana palekana maikaʻi, hoʻokahi mīkini no nā kumu he nui a me nā ʻano ʻē aʻe. Ma waho aʻe o ka hoʻopau ʻana i ka ʻimi wai a me ka ʻimi kinoea, hiki iā ia ke hoʻoheheʻe i loko o nā ʻano paʻakikī. Ua lako ia me ka reaming drill bits a pela aku. Hiki ke hoʻohana ʻia ka mea hoʻoheheʻe no ka wili ʻana. ...

ʻO 900mm ka laulā a me 2500mm ka lōʻihi, a hiki ke hana ʻia e like me ka nui o ke alanui.

ʻEli Tunnel a me ka hana ʻana ma lalo o ka honua

ʻO ka hoʻoheheʻe ʻana o ka tunnel no nā papahana ʻenehana: Crawler piha hydraulic tunnel drilling rigs ua hoʻohana nui ʻia i ka hana ʻana i nā hana ʻenehana e like me nā alaloa, nā alahao, nā subways, a me nā kahawai wai. Hiki i kēia mau rigs ke wili ma ka pōhaku, ka lepo, a me nā mea ʻē aʻe e hana ai i nā tunnels no ka lawe ʻana, nā pono hana, a i ʻole nā ​​​​mea hana lalo. ʻO ko lākou hiki ke hana ma nā wahi paʻa a ma lalo o nā kūlana paʻakikī e pono ai lākou no ka ʻeli ʻana i ka tunnel nui.

Nā hana mining

Underground Mine Development: Ma nā hana mining, crawler full hydraulic tunnel drilling rigs e hoʻohana ʻia no ka wili ʻana i nā ʻāpana tunnel a me nā adits e komo i nā waihona mineral. Hiki iā lākou ke ʻeli i nā tunnels ma nā ʻano ʻano honua like ʻole, e like me ka pōhaku paʻa a me ka lepo i hui pū ʻia, e hana i nā ala komo no nā lako a me nā limahana hana.

Nā Papahana Hoʻomalu Wai

ʻO ka wili ʻana no nā Tunnels Hydroelectric: He mea nui ka Crawler piha hydraulic tunnel drilling rigs i ke kūkulu ʻana i nā mea kanu hydroelectric, kahi e hoʻohana ʻia ai e wili i nā tunnels no ka hoʻololi ʻana i ka wai, ka hana mana, a me ka lawe ʻana. Hiki i kēia mau rigs ke wili ma o nā ʻano kūlohelohe like ʻole e hana i nā tunnel lawe wai, e hōʻoia i ka holo mālie o ka wai i nā turbines.
