Kayan Aiki na PDC Drag

PDC drag bits suna da mahimmanci a cikin ayyukan drilling na foundation engineering da geotechnical site investigation. Waɗannan polycrystalline diamond compact bits suna da fixed cutting elements badala da rolling cones, wanda ya sa su zama da amfani a cikin rotary drilling applications a cikin ayyukan deep foundation. PDC drag bits suna aiki don karya rock formations ta hanyar rotational motion, wanda ke cire material layer by layer lokacin da drilling rig ke aiwatar da downward pressure da rotational force. A cikin yanayin ayyukan deep foundation, waɗannan bits suna da mahimmanci don boring exploratory boreholes, soil sampling, da foundation design phase investigations inda masu aikin goni suka buƙaci bincika hali na ƙasa da ƙasa kafin pile driving, caisson installation, ko sauran ayyukan gine-gine na deep foundation.
