Umhlinzeki we-API we-HDD Hole yokuvula i-hard rock drilling
Incazelo Yomkhiqizo
Ama-Horizontal Hole Openers, awaziwa nangokuthi ama-HDD Reamers, asetshenziselwa ukukhulisa imbobo yokuhlola ku-Horizontal Directional Drilling(HDD)
I-HDD isetshenziswa lapho ukugenca nokumba kungenzeki.
Lobu buchwepheshe bokubhoboza buvumela indlela eqinile yokumba ngaphansi komhlaba.
Kunezigaba ezintathu:
1>isigaba sokuqala ukubhoboza imbobo encane yokulinga eyi-diameter.
2>Isigaba sesibili siwukukhulisa imbobo ngethuluzi lokusika i-diameter elikhudlwana elibizwa ngokuthi i-HDD Reamer, i-Rock Reamer noma i-Hole Opener.
3>Isigaba sesithathu ukufaka ipayipi le-casing noma omunye umkhiqizo emgodini okhulisiwe
