umahluko phakathi kokubhola ngokuthe nkqo, ukubhola okujikelezayo kunye nokungenamigxobhozo ye-HDD

Inkcazo: Indlela yendabuko yokugrumba edala imingxunya ethe nkqo kumphezulu woMhlaba ukuze kufikelele kwizixhobo ezingaphantsi komhlaba okanye kwakhiwe izakhiwo ezithe nkqo.

Umgaqo Wokusebenza: I-drill bit ejikelezayo (umz., i-tricone, i-PDC bit) iqhutywa iye ezantsi ngamandla oomatshini okanye e-hydraulic. Ulwelo lokubhola (udaka) luyajikeleziswa ukuze lupholise i-bit, lususe iingceba, kwaye luzinzise iindonga ze-borehole.​

Izicelo eziphambili:

• Ukukhupha ioyile, igesi yendalo, okanye iiminerali (umz., amalahle, iisinyithi).

• Ukugrumba imithombo yamanzi, imithombo yobushushu bomhlaba, okanye imithombo yokubeka esweni uphando lokusingqongileyo.

Iingenelo: Ubungakanani bobunzulu obuphezulu (ukuya kuthi ga kumawaka eemitha), ulungelelwaniso oluchanekileyo oluthe nkqo, kunye nokufaneleka kokwakheka kwamatye aqinileyo.

Imida: Ifuna indawo enkulu yomphezulu, iphazamisa umhlaba ongaphezulu, kwaye ayikwazi ukuhamba imiqobo ethe tye (umz., imilambo, iindlela).

2. Iibhodi ezijikelezayo​

Inkcazo: Indlela yokwakha isiseko ekhethekileyo ebhoboza imingxunya ethe nkqo okanye etyekele kancinci ukufaka iipali zekhonkrithi, zentsimbi, okanye ezidityanisiweyo (izakhiwo ezithwala umthwalo kwizakhiwo/iibhulorho).

Umgaqo Wokusebenza: Isixhobo sokubhola esijikelezayo sisebenzisa ibhakethi yokubhola engenanto okanye i-auger ukumba umhlaba/amatye. Emva kokwenza umngxuma, kufakwa iikheyiji zokuqinisa, kwaye kugalelwa ikhonkrithi (ngokufuthi phantsi koxinzelelo) ukwenza inqwaba.​

Izicelo eziphambili:

• Ukwakha iziseko zee-high-up, iibhulorho, amazibuko, okanye izakhiwo zoshishino (ukusasaza imithwalo yesakhiwo kwiindawo ezizinzileyo ezingaphantsi komhlaba).

• Ukuzinzisa amathambeka okanye ukulungisa iziseko ezikhoyo.

Iingenelo: Ukwakheka kweenqwaba ngokukhawuleza, kuyaqhelana nomhlaba owahlukeneyo (udongwe, isanti, amatye athambileyo), kwaye kunciphisa ukungcangcazela xa kuthelekiswa nokufakwa kweehammer.​

Imida: Ifuna ukulungiswa komphezulu othe tyaba, inokubangela ukudilika kwemingxuma yomhlaba okhululekileyo (ifuna isingxobo), kwaye ilinganiselwe kubunzulu obunganzulu ukuya kobuphakathi (ngesiqhelo ngaphantsi kweemitha ezili-100).​

3. I-HDD Trenchless (Ukubhola Ngokuthe Tye)​

Inkcazo: Indlela entsha "engagrumbi" egrumba imingxuma ethe tye okanye ethe tye phantsi komhlaba ukuze kufakwe izixhobo ezingaphantsi komhlaba (iipayipi, iintambo) ngaphandle kokwemba imisele.​

Umgaqo Wokusebenza:

1. "Umngxuma wokuhlola" omncinci ugqojozwa kwindlela ethe tye eyilwe kwangaphambili kusetyenziswa intloko yokubhola ekwaziyo ukujika (ekhokelwa yiGPS okanye iigyroscopes).​

2. Umngxuma wovavanyo uyandiswa (ulungisiwe) ukuze ulingane nobubanzi bombane.

3. Umbhobho/intambo yombane itsalwa ngasemva ngequla elikhulu.

Izicelo eziphambili:

• Ukufaka imibhobho yamanzi/yogutyulo, imigca yegesi, okanye iintambo ze-fiber-optic phantsi kweendlela, oololiwe, imilambo, izikhululo zeenqwelo-moya, okanye iindawo ezinobuthathaka kokusingqongileyo (umz., iindawo ezimanzi).​

Iingenelo: Ukuphazamiseka okuncinci komphezulu (akukho kugrunjwa kwemisele), kugcina iziseko zophuhliso/ukuhamba kwezithuthi, kwaye kunciphisa impembelelo kwindalo esingqongileyo.

Imida: Ubungakanani bobunzulu obuphantsi (ngesiqhelo ngaphantsi kweemitha ezili-100), bunqunyelwe kumhlaba othambileyo ukuya kophakathi (ilitye eliqinileyo liyanyusa iindleko), kwaye lifuna ukuhamba ngokuchanekileyo (umngcipheko wokuphambuka kwendlela yokumba).
