Intshayelelo ngokubanzi:
I-DTH drill rods (ekwabizwa ngokuba ziityhubhu zokubhola okanye imibhobho yokomba) yindlela yokudlulisa amandla empembelelo kunye netorque ejikelezayo kwiihamile kunye neebhithi ze-DTH, kunye nokunikezela ngokudlula kokuhamba komoya.
Ngokomgaqo, intonga ekhaphukhaphu, kungcono ukuba isebenze. Ngoko ke obhityileyo usoloko ekhethwa kunomjiva ukuba ezinye iiparamitha bezifana. Ngelixa okwangoku, amandla esivuno kunye namandla okuqina nawo kufuneka athathelwe ingqalelo, okuthetha ukuba ubukhulu bodonga lwentonga buyafuneka ukufumana amandla aneleyo. Ewe kunjalo, xa ubungqingqwa bucelwe ngokungqongqo buncinci kangangoko ukunciphisa ubunzima bomtya we-drill, kukwakho nenye indlela yokufumana iityhubhu zokubhola ezizezona zisebenzisa iintsimbi zomgangatho ongcono.
I-Plato ine-DTH drill rods ezinoyilo oluninzi olwahlukeneyo lobukhulu bedayamitha nganye, ezenziwe kwiintsimbi zebakala ezahlukeneyo zokukhethwa. Ke ngoko, ekusebenzeni ukomba endle, phantsi kweemeko ezahlukeneyo, kunokubakho isidingo seentlobo ezahlukeneyo zeentonga zokomba kwisicelo esithile. Umzekelo, ezityebileyo ezinemigangatho yentsimbi ekumgangatho ophezulu jikelele yokugrumba umngxuma wobunzulu obuphakathi, njengemingxuma yokuqhushumba; kwaye ezi zibhityileyo zinentsimbi yomgangatho ongcono wokomba umngxuma onzulu kakhulu, njengokugrumba i-thermal yomhlaba. Ngapha koko, iintonga ze-Plato DTH zokubhola ziphathwa kakuhle ngobushushu, ngokuchanekileyo zenziwe, kunye ne-friction-welded.
