Dugukoloko porozɛw jɔli masinw ye ankɔri masinw ye, jirituru ni fɛnw falen-falen masinw, faraw dilanni, fɛn minnu bɛ kɛ ka fɛnw sɔgɔ, ani jibɔ masin minnu bɛ kɛ ka caya. Kabɛli sira ta min bɛ kɛ kuluw la, a ka c’a la, o bɛ jɔ waati kelen na ni dugukolo baara porozɛw ye, wa a bɛ se ka kɛ layini jɔli bɛɛ la.
Ankɔri masinw bɛ kɛ ka ankɔri kuluw ka pilan jigincogo baara kɛ. A ka c’a la, tarakitɛri minnu bɛ kɛ ni wotoro ye walima minnu bɛ kɛ ni nɛgɛ ye, mobili, ani sɛgɛsɛgɛlikɛlanw, olu bɛ kɛ ni pilan bolibagaw ka so jɔli minɛnw ye minnu ka kan.
Fɛnɲɛnɛmaw ni fɛnw falen-falen masinw bɛ kɛ ka jusigilanw dingɛw sɔgɔ minnu bɛ tilennen-Barrel bored piles ani expanded-Bottom Bored Piles. Drilling and expanding baara senfɛ, dugukolo bɛ fɔlɔ ka sɔgɔ fo ka se a jugumanba ma, o kɔfɛ, drilling kun bɛ da wuli dɔɔnin dɔɔnin fɛɛrɛ kɛrɛnkɛrɛnnen dɔ fɛ walasa ka duguma dingɛ bonya, ani laban na, alikama- i n’a fɔ jusigilan dingɛ bɛ dilan. Drilling ni expanding machine jogo ye standardized hole formation ye, tigɛ tɛmɛnen si tɛ, ani dugukolo fɔlɔ fanga bɛ se ka mara.
Farakurunw ye fɛnw ye minnu bɛ se ka kɛ ka faraw bila ka fara dingɛw kan Pole Tower Foundation jɔli kama kuluyɔrɔw la. A bɛ kɛ ka caya ni kɔnɔna na faraw ye minnu bɛ jeni ani pneumatic rock drills.
(1) Kɔnɔna na, farakurun min bɛ jeni, o bɛ kɛ ni gazi motɛri fila ye-Stroke gazoli ni faraw. Motɛri piston ni rock drill impact piston bɛ silinda kelen na.
(2) Nɛgɛsira-Type pneumatic rock drill, n’a bɛ fɔ fana ko farakurun-dɔrɔgu, o ye fara-dɔgɔtɔrɔso ni fara-ji-minɛn (walima jɔyɔrɔ) faralen ye ɲɔgɔn kan. A bɛ se ka kɛ ka drill (480-130 mm) ani ka juguya (fo ka se m 30 ma, ka fara drill bere dingɛw kan) fara dingɛw kɔnɔ.
