Kayan Aiki na Down-The-Hole (DTH) Hammer

Bit na Down-The-Hole (DTH) na hammer wakilci fasalin fasaha na bugun bugun da ke da mahimmanci ga ayyukan gine-gine na kasa da na geotechnical. Wadannan kayan aikin gini na stainless steel ko tungsten carbide-tipped suna aiki a cikin DTH hammer systems, suna kawo bugun bugun sauri don karyata kasa da strata mai kauri a lokacin kirkirar borehole. Duk da haka da hanyoyin bugun rotary, DTH percussion drilling na amfani da watsa wutar ta hanyar drill string don kai hammer bit daidai a kan borehole face, wanda ke ba da darajar shiga cikin kasa mai kauri da kundin kayan. Fasahar bugun bugun dai dai mahimmanci ne ga shirye-shiryen gini, kwakwalwa bore installation, da binciken bugun inda na'urorin rotary na gargajiya suka sami raguwa. Tsarin bit na amfani da pneumatic ko hydraulic percussion hammers, tare da diameters daban-daban daga 25mm zuwa sama da 150mm, wanda ke ba masu aikin gini damar za su zaɓi kayan aikin da ya dace tare da yanayin kasa na ƙasa da buƙatun aikin.
