Hoʻolauna nui:

ʻO ODEX (pōkole no "Overburden Drilling Excentric") kapa ʻia ʻo Stratex, Tubex a i ʻole ODS. He hoʻololi ia o ka hāmare DTH ea. ʻO ia me kahi swing-out eccentric bit e ream i lalo o ka pahu. A ʻo ka bit percussion he ʻelua ʻāpana ʻōlelo aʻoaʻo paʻa: he bit pilot concentric, a ma hope o ia he bit reamer eccentric e koli ana i waho e hoʻonui i ke anawaena lua i ka wā e wili ai. Ma hope o ka bit eccentric he mea alakaʻi e hoʻokomo i kahi kāmaʻa pahu poʻohiwi kūloko kūikawā ma lalo o ka pahu ODEX. No laila, huki ʻia ka ODEX e ke kaula drill i ka wā e holomua ana ka puka. Pahu nā ʻokiʻoki ma ka ʻāpana annulus ma waena o ka mea alakaʻi a me nā kāmaʻa pahu i kahi wili e alakaʻi iā lākou i ka lepo a i kahi ʻohi laʻana.

ʻO nā ʻōnaehana ODEX nā ʻōnaehana ʻoi aku ka maikaʻi loa no ka hoʻoheheʻe ʻana i nā pahu i nā kūlana ʻāina maʻamau. He mea kaulana loa lākou me nā mea hana ʻaelike wili no ka hoʻopaʻa ʻana i loko o nā pūnāwai wai, nā pūnāwai geothermal, ka lua mini-type grouting o ka hale, ka pāhana a me ke awa, a me ka hana micro-piling pāpaʻu. Ma muli o ke akamai o ka ʻēheu reaming, hiki ke kiʻi ʻia ka bit a hiki ke hoʻohana hou ʻia. He mea kūpono ʻo ODEX no nā puka pōkole i loko o ka overburden homogenous, mahalo i nā pōmaikaʻi maikaʻi loa e like me ke ʻano maʻalahi, ka hana maʻalahi, nā mea hana wili hoʻihoʻi, ke ola lōʻihi a me ka maikaʻi. ʻO nā hiʻohiʻona wili o nā ʻōnaehana ODEX e like me ka DTH hammer drilling method, e like me:

Hoʻopau wikiwiki i nā ʻokiʻoki;

Kiʻekiʻe ke komo ʻana, ʻoi aku ka maikaʻi ma ka hoʻokumu ʻana i nā pōhaku kūʻokoʻa (e like me ka basalt);

ʻO ka maʻalahi o ka lepo a me ka wai lepo i ka wā e wili ai;

Hiki ke ana i ka manao hua ma ka hohonu i kohoia i ka hookumu ana;

ʻOi aku ka maikaʻi i nā hoʻokumu ʻole ʻia me ka pilikia nui o ke ana (ʻo ia paha ka hiʻohiʻona nui loa).

Loaʻa iā PLATO nā ʻano ODEX mai ka ODEX90 a i ka ODEX280, i hana ʻia me nā shanks o ka hapa nui o nā hāmare DTH lanakila mai ka 3" a hiki i ka 10". Loaʻa iā lākou a pau me nā mea alakaʻi, nā kāmaʻa Casing, Eccentric Reamer, Pilot Bit, Guide Sleeve, a me nā Kit Locking.
