Overburden Drill Bit / Eccentric Laum Bit
Overburden Drilling cuab yeej
ODEX systems rau DTH hammers uas tau tsim tshwj xeeb rau kev xyaum thiab cov ntaub ntawv ib txhij los ntawm overburden.Cov cuab yeej ruaj khov overburden drilling tau yooj yim dhau los ntawm cov pob zeb loj rau rub lub teeb hnyav uas pheej yig casings tau suav nrog hauv qab lawv.Cov cuab yeej overburden drilling no yooj yim tshem tawm ntawm lub qhov / qhov tob thiab muab rau peb cov neeg siv khoom hauv cov lus qhia nram qab no:
1. Siv rau qhov drilling qhov twg cov pob zeb tsim yog overburden thiab xav tau lub raj casing los txhawb.
2. hloov tau qhib thiab kaw.
3. Daim Ntawv Thov Ntau Yam: Nws yog tsim rau drilling qhov dej, qhov dej kub hauv qhov dej, thiab luv luv miscopies nruab nrab mini-hom grouting qhov ntawm lub tsev, lub pas dej ua ke thiab cov chaw nres nkoj.
4. Cov Ntsiab Cai Tsim: Ua kom lub casing ua raws li yooj yim thiab cov khoom siv thiab kev ua haujlwm yooj yim
5. Cov txiaj ntsig zoo: Cov qauv yooj yim, kev ua haujlwm yooj yim, txhim khu kev qha zoo, cov cuab yeej drilling rov qab tau, lub neej ua haujlwm ntev.
6. Pem hauv ntej pob nrog cartons, txheej txheej nrog ntoo rooj
