1.Ubwubatsi
Irinde gutandukana kumurongo no gushiraho imiterere ya "S" mubwubatsi buyobowe.
Mubikorwa byo kubakagucukura icyerekezounyuze, niba umwobo uyobora woroshye cyangwa utari mwiza, waba uhuye nigishushanyo mbonera cyambere, kandi ukirinda kugaragara kumiterere ya "S" yumwobo uyobora nicyo gisabwa kugirango urangize neza kubaka kwambuka.Kugira ngo wirinde gushiraho imiterere ya “S”, ingamba zikurikira zirashobora gufatwa:
1
（2） Mbere yo gucukura, igikoresho cyo gucukura kirahagarikwa, hamwe ningingo nyinshi zo gupima inshuro nyinshi kugirango tumenye neza.
.Mubikorwa byo gucukura, ukurikije aho gucukura imiterere yimiterere kugirango igenzure imikorere yibyondo byicyondo, umwanya uwariwo wose ukurikije imiterere ya geologiya kugirango uhindure umuvuduko wibyondo, igipimo cyibyondo nibindi bipimo.
. imiterere ya "S" y'umuyoboro wimyitozo muburyo bwo gushiraho kugirango harebwe neza umurongo ucukura no kunoza ubwiza bwumwobo windege.
.Gupima inguni ya azimuth ikorwa kumpande zombi zashyinguwe hamwe nubucukuzi.
（6） Igiceri kigomba guhishwa hejuru y’umurongo wambukiranya, kandi gutandukana bigomba gupimwa kenshi kugirango harebwe niba umurongo wambukiranya uhuza igishushanyo mbonera hamwe n’ubucukuzi bw’ikirundo cyo hejuru hejuru y’ahantu hacukuwe.
（7 records Inyandiko zigenzura ibyerekezo zigomba kuba zuzuye, zuzuye kandi neza.Mugihe cyo gucukura umwobo wicyitegererezo, ibintu byose bidasanzwe no guhagarika gucukura bigomba kwandikwa.
（8） Reba itandukaniro ryumuvuduko wibyondo nimpinduka zibyondo igihe cyose kugirango utange ishingiro ryo gusuzuma imikorere ya pompe yicyondo;kwitegereza ihinduka ryumuvuduko wo gusunika kugirango utange ishingiro ryimikorere yigikoresho cyo gucukura.
. kugenzura kalibrasi kugenzura, amakuru, nibindi) guhora umenya.Nyuma y'ibizamini byose nibihinduka birangiye, komeza ucukure bisanzwe.
2.Umutint gupima iyo myitozo ya biti
.Muri iki gihe, itara ryakozwe na moteri y'ibyondo ntirishobora gutsinda ibikorwa bya torque ya rutare kuri biti ya myitozo, biti ya myitozo ihagarika kuzunguruka.
Hariho inzira ebyiri:
? urutare vuba, gabanya itandukaniro ryumuvuduko wibyondo, hanyuma ukoreshe buhoro Thrust hanyuma utere umuvuduko wihuta;
? ku kashe.
.Impamvu nyamukuru ni uko gutandukana kw'ibice bitandukanye ari binini cyane, gusukura umwobo ntabwo byuzuye, kwirundanya cyane gutema ibice byatewe na "umwobo wo kugabanuka", bikaviramo gucukura.
Umuti: Icya mbere, icyondo kigomba gukomeza gukora mubisanzwe, kandi hari ibyondo bihagije byo kuvoma mu mwobo.Muri iki gihe, umuyoboro wimyitozo ntugomba gukomeza gusubira inyuma, bitabaye ibyo uzahita uhagarara.Umuyoboro wimyitozo ugomba gukomeza gutera imbere hamwe no kuvoma ibyondo, wihangane usukure umwobo, uhindure impande ndende ya biti ukurikije inyandiko ya mbere yo gucukura, guhagarika kuzenguruka umuyoboro wimyitozo usubiza inyuma, witondere kugenzura impagarara zuruganda. , hanyuma uzenguruke umuyoboro wimyitozo imbere, usukure umwobo, inshuro nyinshi, kugeza byoroshye unyuze mugice cya "shrinkage".
3.Kwubaka
(1) Kurwanya kugwa kwa cone mu mwobo mugihe cyo gusubiramo
Mugihe cyo kongera kubaka, kubera imbaraga zurutare rwinshi cyangwa imiterere ihindagurika ryurutare, cone reamer irashobora kugwa mumwobo, bikagira ingaruka kumyubakire ikurikira.
Uburyo bwo kuvura: Ukurikije amakuru yubuyobozi bwanditse, impinduka ziterwa na buri gice cyurutare zirashobora kugenwa.Nyuma ya rock reamer imaze gukoreshwa amasaha 80, iyisimbuze iyindi nshyashya;Mbere yuko reamer yinjira mukarere aho imihangayiko yiyongera, niba urutare rukoreshwa mumasaha arenga 60, rusimbuze urundi rushya.
(2) Kurwanya ingamba zacitse reaming umuyoboro
Kwambukiranya geologiya yumushinga ntibingana mubukomere no gukomera, kandi ibisabwa kugirango reaming ibe nziza ni byinshi cyane.Iyo uhuye nahantu hafite impinduka nini mukibazo cyurutare mugihe cyo gusubiramo, biroroshye gutera kuvunika imiyoboro ya drill, bigaragazwa no kugabanuka ako kanya kugabanuka kwimyitozo nuburemere.
Uburyo bwo kuvura: mugihe cyagucukura icyerekezokubaka, inzira yo kubaka ihuza imiyoboro ya dring ahacukurwa.Umuyoboro wimyitozo umaze kumeneka, hindura mugihe ibikoresho kugirango ucukure hanyuma usubize inyuma reamer.Nyuma yo kuroba imiyoboro yose ya dring reamers, sisitemu yo kuyobora igomba gushyirwa kuruhande rwubutaka kugirango yongere kuyobora ku mwobo wambere.
Gookma Technology Industry Company Limitedni uruganda rukora tekinoroji hamwe nu ruganda ruyoboraimashini itambutsa icyerekezomu Bushinwa.
