Umthengisi we-API we-HDD Hole yokuvula i-hard rock yokomba
Ingcaciso yeMveliso
IziVuli zemingxuma eHorizontal, ekwaziwa ngokuba zii-HDD Reaamers, zisetyenziselwa ukukhulisa umngxuma wokulingwa kwi-Horizontal Directional Drilling(HDD)
I-HDD isetyenziswa xa ukugrumba kunye nokugrumba akwenzeki.
Obu buchwephesha bokomba buvumela indlela eqhubelekayo yokugrumba ngaphantsi komhlaba.
Kukho izigaba ezithathu:
1>inqanaba lokuqala kukugrumba umngxuma olingwayo omncinci.
2>Inqanaba lesibini kukwandisa umngxuma ngesixhobo sokusika esikhulu esibizwa ngokuba yi-HDD Reamer, iRock Reamer okanye iHole Opener.
3>Inqanaba lesithathu lifaka umbhobho we-casing okanye enye imveliso kumngxuma owandisiweyo
