Nov yog yuav ua li cas nws muab qhov kom zoo dua thiab qhov twg nws zoo tshaj plaws:
Qhov "Double-Cov Boom" txhais li cas
Ib ob - nkhaus (ob -khoov) boom muajob articulated bending ntsiab luses ib. Qhov no tso cai rau kev xyaum ua:
Mus txogUpper crown, sidewalls, thiab inverttsis txav tus cab kuj
Laum ntawmloj ntsug thiab kab rov tav kaum
Tsis txhob cuam tshuam nrog qhov ribs thiab kev txhawb nqa
Yog vim li cas nws ua tau "Ob Efficiency"
1. Kev them nyiaj ntau dua los ntawm Ib Txoj Haujlwm
Ib qhov chaw nres tsheb tuaj yeem npogyuav luag tag nrho lub ntsej muag
Tsawg tus neeg nqa khoom txav →luv dua drilling voj voog
Tshwj xeeb tshaj yog zoo nyob rau hauv6-10 m dav tunnels
✅ Cov txiaj ntsig:Ntau qhov drilled rau ib qho kev hloov
2. Ceev dua lub ntsej muag Drilling
Yooj yim thiab nrawm dua kev sib dhos ntawm cov tho qhov
Yooj yim hloov ntawmtxiav qhov, perimeter qhov, thiab lifters
Txo lub sij hawm siv kho boom txoj hauj lwm
✅ Cov txiaj ntsig:Ntau dua meters drilled ib teev
3. Ib lub tshuab, ntau yam haujlwm
Muab ob npaug rau- nkhaus boom jumbos tuaj yeem siv rau:
Lub ntsej muag drilling
Ru tsev bolting
Sidewall thauj tog rau nkoj installation
Qhov no hloov ntau lub tshuab lossis rov teeb tsa dua.
✅ Cov txiaj ntsig:Kev siv cov cuab yeej siv siab dua
4. Kev ua tau zoo dua nyob rau hauv complex Geology
Haum rauChav Kawm II-IV nyob ib puag ncig pob zeb
Txhim kho qhov tseeb drilling txawm nyob rau hauv lub ntsej muag tawg los yog tsis sib xws
Stable boom geometry txhim kho qhov ncaj
✅ Cov txiaj ntsig:Tsawg dua -drilling thiab txo cov khoom tawg
Kev sib piv kev ua tau zoo
| Yam khoom | Ncaj Boom | Ib leeg -Cov Boom | Muab ob npaug rau-Cov Boom |
|---|---|---|---|
| Kev npog ntsej muag | txwv | Nruab nrab | Loj heev |
| Repositioning zaus | Siab | Nruab nrab | Tsawg |
| Drilling ceev | Ib txwm | Ceev dua | Siab tshaj |
| Ntau yam | Tsawg | Nruab nrab | Siab |
Ideal Application Scenarios
Txoj kev loj & railway tunnels
Hydropower tunnels (raws li koj tau nug txog ua ntej)
Nruab nrab mus rau loj hla -section tunnels (Ntau dua lossis sib npaug li 5 × 5 m)
Tej yaam num yuav tsum tauceev ceev ua ntej tus nqi
Cov ntsiab lus
A ob -kho pob zeb drilling jumbomuab "ob chav efficiency" los ntawm:
Minimizing repositioning
Maximizing lub ntsej muag npog
Combining tunneling thiab bolting muaj nuj nqi
Txhim kho qhov drilling raug thiab ceev
Yog tias koj xav tau, tsuas yog qhia rau peb koj qhov tunnel seem thiab chav kawm pob zeb.
