Kayan Aiki na Rock Roller (Tricone)

Rock roller tricone bits suna da mahimmanci a cikin ayyukan drilling na deep foundation, musamman lokacin da aka sadu da rock formations da hali na ƙasa. Waɗannan kayayyakin suna da three rotating cones da aka sanya da hardened steel ko tungsten carbide inserts, wanda ke aiki tare don karya da rock material lokacin da bit ke shiga cikin borehole. Tsarin tricone roller bit ya zama ma'auni a cikin ayyukan gine-gine na foundation wanda ke buƙatar shiga cikin limestone, sandstone, granite, shale, da mixed rock strata. Aikin su na mechanic ya banbanta da fixed-cutter bits, wanda ya sa su zama zaɓi na farko lokacin da aka yi drilling boreholes don large-diameter foundations, pile driving operations, da geotechnical exploration inda rock breakdown efficiency da bit durability suka yi daidai. Three cones masu rotation suna rarraba drilling loads evenly, wanda ke rage heat generation da kuma karuwa bit life wanda ke riƙe da inganci na hole don gine-gine da shigarwa.
