I .Introduction ofR.C.Ka wili ʻana

ʻO ka drilling RC, i kapa ʻia ʻo "Centre Sample Recovery" a i ʻole "Dual Wall Drilling", e hoʻohana ana i kahi paipu pālua ʻelua kahi e hoʻoheheʻe ʻia ai ka ea wili, maʻamau kiʻekiʻe, ma waena o nā paipu waho a me loko a hiki i ka maka o ka bit drilling. kahi e hoʻihoʻi ʻia ai ka paipu waena me ka laʻana i ʻoki ʻia e ka bit drill.

Ⅱ .ʻO ka hoʻohana a me nā pono o ka RCDTH Hammer:

1) ʻAʻohe ʻino

ʻOhi ka ʻōnaehana RC i ka laʻana ma o nā puka hoʻihoʻi i ke alo o ka drill bit i ka wā i hana ʻia ai nā ʻokiʻoki a i ʻole ka laʻana.ʻAʻole pono ka laʻana i wili ʻia e hele i ka lōʻihi o ka hāmare kahi i hoʻopōʻino ʻia a nalowale ka laʻana.

2) ʻOi aku ka hana kiʻekiʻe

I nā kūlana o ka ʻāina haʻihaʻi a haʻihaʻi, e hana pinepine ka RC i ka hāmare maʻamau e pili ana i nā helu penetratiion.

3) Laʻana Māloʻo

ʻOiai ma kekahi mau ʻāpana wai e hiki nō ke hōʻiliʻili i kahi hāpana maloʻo no ka mea ua ʻohi ʻia nā ʻokiʻoki (sample) i ka wā i hana ʻia ai lākou ma ka maka o ka drill bit.

4) Hoʻihoʻi Laʻana Kiʻekiʻe

Ma muli o ka hōʻiliʻili ʻia ʻana o ka hāpana ma ke alo o ka bit drill ʻaʻole e nalowale ka laʻana i ka wā e wili ai i ka ʻāina haʻihaʻi a haʻihaʻi paha.A ma muli o ka hoʻohālikelike ʻana o ka bit me ka nui o ka chuck, ʻaʻole liʻiliʻi loa ke kaʻe ʻana o ka laʻana a me nā helu hoʻihoʻi o, a hiki i ka 98% hiki ke loaʻa.
