Los txiav txim seb lubqhov ntev ntawm pob zeb drilling jumbo zoo kawg nkaus phim lub qhov hla ntawm -sectional dimensions, koj yuav tsum xyuas cov ntsiab lus hauv qab no ib ntus:
1. Paub meej tias qhov hla hla- ntu ntu
Tau txais covtsim duab kos duabntawm lub qhov thiab qhia meej meej:
Qhov dav dav (hauv qab thiab qhov siab tshaj plaws)
Qhov siab
Qhov zoo (horseshoe, ncig, rectangular, thiab lwm yam)
Arch radius thiab sidewall curvature
Kev tsim kho clearance (kev nyab xeeb margin)
Cov nqi no tsim covlub hnab ntawv hauv pauslub jumbo yuav tsum haum rau hauv.
2. Tshawb xyuas lub pob zeb drilling jumbo tag nrho qhov ntev
Los ntawm cov chaw tsim khoom cov ntaub ntawv technical, paub meej tias:
Zuag qhia tag nrho dav, qhov siab, thiab ntev
Yam tsawg kawg nkaus ua haujlwm siab
Hloov lub vojvoog
Thauj dav (tseem ceeb rau kev nkag tunnels)
👉 Lub jumbotag nrho qhov siab thiab qhov dav yuav tsum yog me dua li qhov profile, nrog kev tshem tawm txaus rau kev ua haujlwm nyab xeeb.
3. Txheeb xyuas qhov kev tiv thaiv boom tiv thaiv qhov profile
Qhov no yog kauj ruam tseem ceeb tshaj plaws.
Tshawb xyuas:
Qhov siab tshaj plaws drilling qhov siab ntawm lub boom
Kab rov tav ncav cuag
Drilling npog dav
Muaj peev xwm tho qhovcrown, xub pwg nyom, sidewalls, thiab invert
Lub jumbo zoo sib xws yuav tsum:
Npog100% ntawm excavation profile
Mus txog lub arch thiab ces kaumtsis muaj repositioning los yog boom kaum sab xis
Tsis txhob pom qhov muag tsis pom qhov chaw ze ntawm qhov qhov contour
4. Sib piv propulsion beam (feed) ntev nrog lub qhov tob
Xyuas kom meej:
Pub ntev Ntau dua los yog sib npaug rau qhov tsim lub qhov tob tob
Pub tuaj yeem laum ntawm cov ces kaum xav tau (kiv cua-zoo li tus lossis qhov sib npaug)
Tsis muaj kev cuam tshuam ntawm cov khoom noj, qhov phab ntsa, lossis koov
Piv txwv li:
4.5 m qhov ua ntej → Ntau dua lossis sib npaug rau 4.8-5.0 m pub ntev yog pom zoo
5. Tshawb xyuas kev tshem tawm thaum ua haujlwm
Cia kev nyab xeeb clearance rau:
Boom viav vias thiab kev sib hloov
Tus neeg teb xov tooj cabin lossis chaw taws teeb - tswj kev pom
Cov kab hluav taws xob cua, teeb pom kev zoo, thiab cov tais cable
Ib yam kev nyab xeeb clearance:
Ntau tshaj lossis sib npaug li 300-500 mmnruab nrab ntawm lub tshuab thiab qhov phab ntsa / arch
6. Simulate lossis overlay profiles (zoo tshaj plaws)
Txoj kev ntseeg siab tshaj plaws yog:
Overlay lubjumbo hnab ntawv ua haujlwmmus rau ntawmqhov hla -sectional drawing
Los yog siv 3D simulation / CAD sib piv
Yog tias lub hnab ntawv boom npog tag nrho lub qhov profile yam tsis muaj kev cuam tshuam, qhov sib tw yog qhov tseeb.
7. Kev txheeb xyuas qhov chaw (ntawm -qhov chaw lees paub)
Ua ntej ua haujlwm tag nrho:
Tsav lub jumbo mus rau hauv lub qhov
Ua qhov chaw sim thiab boom extension
Paub meej tias tsis muaj kev sib tsoo, qhov muag tsis pom kev, lossis ncav cuag tsis txaus
Yog tias koj xav tau, koj tuaj yeem qhia peb:
Qhov hla- ntu loj (dav × qhov siab)
Hom qhov (hydropower, railway, mine, thiab lwm yam)
Ib leeg- npab los yog ob- npab jumbo
Peb tuaj yeem pab kojtxheeb xyuas qhov sib tw lossis pom zoo kom tsim nyog jumbo configuration.
