Xa i-rotary drilling rig isebenza, kusoloko kukho intlenga ephantsi komngxuma, eyona nto iyisiphene esingenakuphepheka se-rotary drilling rig.Ngoko kutheni inentlenga ezantsi komngxuma?Isizathu esona sizathu kukuba inkqubo yayo yokwakha yahlukile.I-rotary drilling rig ithatha indlela yokugaya udaka olungajikeleziyo, kwaye i-slag yokubhoboza ayinakuthwalwa emhlabeni ngokujikeleza kodaka ukuze ihlale phantsi.
Ezi zilandelayo zezona zizathu ziphambili zokwenzeka kwentlenga:
1.Intsalela phakathi kwamazinyo eemele e-rotary drilling rig kunye nesigqubuthelo esisezantsi se-emele yokomba
2.Amazinyo amancinci amancinci ajikelezayo, ngoko ke intlenga phakathi kwamazinyo ayinakuphepheka;
3.Isigqubuthelo esisezantsi sesixhobo sokugaya asivalwanga ngokuqinileyo;
4.Umhlaba onqunywe kumda wangaphandle webhakethi yokugaya i-rotary awukwazi ukungena emlonyeni we-cylinder ngenxa yecala eliphantsi lomngxuma kwaye lihlala emphethweni wezantsi komngxuma;
5.Xa ubhobhoza isanti yodaka kunye ne-flow-plastic formations, i-slag yokubhoboza kwibhakethi ye-drill ilahlekile ngexesha lokunyusa, kwaye ngamanye amaxesha nayo yonke into ilahleka kwi-borehole;
6.I-stroke yokubuya kwebhakethi ye-drill inkulu kakhulu, umthwalo ugcwele kakhulu, kwaye i-muck igxininiswe ngaphandle komngxuma wokukhupha i-cover top.
Ngokomgangatho wesizwe, ubukhulu obujoliswe kuyo be-sediment phantsi komngxuma wokungqubuzana kwengqumba kunye ne-end-bearing pile ayikho ngaphezu kwe-100mm kwaye ayikho ngaphezu kwe-50mm, ngokulandelanayo.
Ezi zingentla zizizathu zokwenzeka kwentlenga ekubunjweni komngxuma wezixhobo zokomba ezincinci ezijikelezayo ezishwankathelwa yiGookma.Nangona esi sisiphako esingenakuthintelwa sezixhobo ezincinci zokomba ezijikelezayo, izixhobo zokomba ezijikelezayo zisengoyena matshini ufanelekileyo wokomba nokufaka inqwaba kweli nqanaba.
Emva kokuba i-rotary drilling rig iqhube umngxuma, kufuneka sihlambulule umngxuma, ukwenzela ukuba i-sediment ephantsi komngxuma ingasuswa.
