Manyan DTH Hammers

Hammer na DTH (Down-The-Hole) na drilling na manya yana da mahimmanci a cikin injiniyarin tushe na zamani, musamman ga ayyuka da aka buƙata na diameters na borehole na manya da high-capacity load-bearing solutions. Ayyukan aikin sun ƙunshi drilling da tono na boreholes na manya diameters tare da amfani da fasahar DTH ta percussion, wacce ke ƙera makamashin impact a fuska ta drill bit ta hanyar downhole hammer mechanism. DTH hammers na manya an tsara su musamman don shiga cikin dense soil strata, weathered rock, da competent bedrock formations a zurfin da, wanda ke sa su muhimmin aikin gina tushe na bored, caisson drilling, da tsarin ƙasa. Fasahar ita ce muhimmi a cikin mazingira na birane da wuraren gini da aka ƙwara inda pile-driving noise da vibration dole ne a rage yayin da ake riƙe da drilling precision da ayyukan aiki. Waɗannan hammers suna aiki ta hanyar canza hydraulic pressure da pneumatic energy zuwa rapid percussion strikes waɗanda ke yaƙar da lalata kayayyakin ƙasa, waɗanda ake cirewa ta hanyar ci gaba na drilling fluid ko compressed air, a kai da yanayin ƙasa da buƙatun aikin.
