Kelly Mai Kasa tare da Mai Haɓaka Torque

Cased kelly tare da torque multiplicator drilling wani aikin horarwa ne na rotary drilling wanda ake amfani da shi sosai a cikin gini na zurfi da geotechnical engineering don tsarin saitin saitin saitin zurfi, diaphragm walls, da ground anchors. Wannan aikin ya amfani da kelly mai kare wanda aka haɓaka tare da ƙarfin torque, wanda ke ba masu aikin horarwa damar samun saurin shiga na horarwa da kiyaye ƙarfin horarwa a cikin yanayin ƙasa mai ƙalubale. Tsarin cased kelly ya kare rod ɗin horarwa daga ƙarfin ƙarfafawa na ɓangaren hagu da gurɓatawa yayin da multiplicator na torque ke ƙara ƙarfin juyin juya hula wanda ake amfani da shi don kayan horarwa, wanda ke ba damar horarwa mai ƙarfi ta hanyar ƙasa mai ƙarfi, mixed strata, da ƙasa mai laka. Wannan haɗin gwiwa na karewa da haɓakawa na torque ya sa aikin zai fi dacewa don aikin gini a cikin muhallin geological mai ƙalubale inda ake amfani da hanyoyin horarwa na al'ada.
