2. Dab tsi cov khoom siv ua kom precast pob zeb ntau lawm muaj cov kab ntau lawm?
Txhawm rau tsim cov railway-cuam tshuam txog cov kab prepast, cov kab ntau lawm feem ntau suav nrog:
| Cuab tam | Kev piav txog |
|---|---|
| QHOB BATCHING COG | Kev Rho Tawm Kev Rho Tawm ntawm Cement, xuab zeb, gravel, thiab ntxiv |
| Ua tov kev tov khoom pob zeb | Ua kom muaj kev sib xyaw ntawm cov khoom siv raw |
| Pwm Pwm / Formwork | High-precision pwm rau sleepers, thaiv, trench npog, thiab lwm yam. |
| Prestoving system (yog tias yuav tsum tau) | Rau lub suab pw tsaug zog lossis cov teeb ci siv steel strands |
| Kev co thiab cov txheej txheem sib xyaw | Ua kom ntseeg tau ntom ntom, tsis muaj chaw nyob dawb |
| Chav los yog nrawm kho Chamber | PASXES LUB ZOG NTXOV RAU HAS-VICAS NTAU LAWM |
| Chaw Nres Tsheb | Nqa thiab rho tawm cov khoom sib xyaw los ntawm cov pwm |
| Conveyors thiab lifting cranes | Rau kev nyab xeeb txav ntawm cov khoom hnyav |
| Kev tswj kom zoo | Rau qhov seem, load-cov kabmob, thiab kev soj ntsuam sab nraud |
3. Yuav ua li cas yog cov khoom lag luam tsim?
Cov kab ntau lawm yog tsim thiab sib sau ua ke los ntawm kev sib txuas:
Cov thav ntawv hlau thiab cov txheej txheem teeb tsa
CNC-machined pwmnrog lub siab ntsuas (tshwj xeeb tshaj yog rau cov neeg tsaug zog)
Tshuab Automation TshuabRau kev sib tsoo, kev co, thiab kev tswj hwm
Hydraulic lossis tshuab tuav tshuab
Prestressing txajRau Tensioning steel cables (yog tias yuav tsum tau)
Txhua kab yog customized nyob ntawm seb nws ua rau cov neeg pw tsaug zog txheem pw, thiab cov hlua khi, lossis cov ciav hlau loj dua .
4. Yuav tsum muaj cov khoom siv twg?
Cov ntaub ntawv tseem ceeb raw muaj xws li:
| Khoom | Lub hom phiaj |
|---|---|
| Cov Portland Mem plab Mement (OPC) | Thawj phau ntawv muaj zog thiab kav ntev |
| Nplua ua ke (xuab zeb) | Ua kom muaj voids, ua kom muaj zog ua haujlwm |
| Coarse aggregates (crushed pob zeb) | Muab lub zog thiab loj |
| Ywg dej | Kev khiav dej ntawm cov xis mas |
| Kev Kho Mob Tus Neeg Kho Mob | Accelerators, Superplasticizers, Huab Cua Autrainers |
| Hlau Hlau Txhawb | Rebars, welded mesh, lossis prest constressing |
| Embedded Qhov Chaw | Ntxig, cable ducts, nqa anchors (raws li yuav tsum tau) |
5. Cov ncauj lus kom ntxaws ntxiv yog dab tsi?
Ntawm no yog tusCov kauj ruam ib theem zuj zus:
Kauj ruam 1: Pwm Teeb
Ntxuav pwm, thov tso tawm tus neeg sawv cev, thiab qhov chaw ua kom rov qab lossis muaj kev sib tw yog xav tau .
Kauj ruam 2: Qhob Batching & Sib Xyaw
Cov ntaub ntawv nyoos yog ntsuas thiab sib xyaw raws tus qauv sib xyaw siv cov nroj tsuag sib xyaw thiab tov khoom thiab tov khoom {{}
Kauj ruam 3: pob zeb ua kom ncuav
Cov qhob yog hliv rau hauv cov pwm thiab tusyees faib .
Kauj ruam 4: Kev co thiab kev sib tw
Kev co tshem tawm cov hnab qhwv cua thiab ua kom nruj nruj rau lub zog .
Kauj ruam 5: Kho
Cov khoom tau kho tau siv chav lossis tswj hluav taws kub kom nrawm lub zog nce .
Kauj Ruam 6: Kev Txhim Kho
Thaum kho tau, Cheebtsam yog cov dab neeg siv hydraulic lossis tshuab nqa kev nqa tshuab .
Kauj ruam 7: Tiav & Zoo Kos
Cov chaw yuav yog av lossis kho, thiab cov khoom tau kuaj xyuas qhov tsis xws luag, qhov ntev, thiab cov ris nra hnyav.
Kauj ruam 8: Kev Cia Khoom & Thauj
Cov khoom lag luam muaj kev nyab xeeb khaws cia kom txog thaum tus me nyuam xa cov phiaj xwm ciav hlau .
{{0 {}} Cov khoom lag luam no tsuas yog siv nyob qhov twg?
Railway precast qhob cov khoom yog qhov tseem ceeb hauv:
| Daim ntawv thov | Kev siv |
|---|---|
| Track Siv | Cov pw tsaug zog, lub hauv paus pads, ballast muaj |
| Rail choj thiab Kam Via | Guaranrasrs, Choj Nkag Mus Txog Kev Nyab Xeeb Kev Nyab Xeeb |
| Kos Npe thiab Cable Tshuab | Trench npog thiab cable kev tiv thaiv |
| Txij Nkawm Teev | Txoj kev, cov ntaub npog hluav taws xob, thiab txhawb nqa cov ntaub qhwv |
