Lub tsheb ciav hlau hu ua dab tsi?
Nyob rau hauv railway engineering thiab kev npaj thauj mus los, txoj kev tsheb ciav hlau feem ntau hu ua "railway track" lossis yooj yim "khiav." Txawm li cas los xij, nyob ntawm cov ntsiab lus ntawm cov txheej txheem, cov qauv tsim, thiab daim ntawv thov, ob peb lwm cov ntsiab lus tseem siv tau.
Ib txoj kev tsheb ciav hlau hais txog cov kab ke ua tiav uas txhawb nqa thiab coj kev tsheb ciav hlau, tsis yog cov hlau rails lawv tus kheej xwb. Nws suav nrog cov tsheb ciav hlau, cov neeg pw tsaug zog (kev sib txuas), kev sib txuas ceev, thiab lub hauv paus txhawb nqa.
Lub sij hawm siv tau dav tshaj plaws yog:
Railway Track- txoj kev ua tiav tas mus li rau kev ua haujlwm tsheb ciav hlau
Khiav- abbreviated engineering term siv nyob rau hauv kos duab thiab specifications
Txoj Kev Mus Ib Txhis (P-Txoj Kev)- ib txwm siv pej xeem engineering lub sij hawm, tshwj xeeb tshaj yog nyob rau hauv British thiab Commonwealth systems, xa mus rau lub taag infrastructure ntawm txoj kev tsheb ciav hlau
Lub luag haujlwm ntawm steel rail yog dab tsi hauv kev tsheb ciav hlau?
Lub luag hauj lwm ntawm steel rails nyob rau hauv ib tug railway khiav yog muab ib tug du, ruaj khov, thiab nruam nto rau lub tsheb ciav hlau log, coj lub tsheb ciav hlau cov kev taw qhia, thiab hloov loj loj ntsug thiab lateral loads rau cov pw tsaug zog, kom muaj kev nyab xeeb thiab muaj zog txav thaum tseem ua ib tug neeg xyuas pib rau signaling systems. Ua los ntawm siab- lub zog steel, rails tsim lub nraub qaum ntawm txoj kev taug kev, txhawb nqa lub tsheb ciav hlau qhov hnyav thiab ua kom yooj yim rau lub log- kev sib tshuam.
- Load Bearing & Distribution:Rails dais qhov hnyav hnyav ntawm lub tsheb ciav hlau thiab faib nws raws li lub siab rau cov neeg pw tsaug zog (ties) thiab ballast, tiv thaiv txoj kev taug kev los ntawm kev poob.
- Kev taw qhia & Kev ruaj ntseg:Lawv muab kev taw qhia rau sab nraud, ua kom lub log ntawm txoj kev raug thiab ua kom muaj kev tswj hwm kev coj ua.
- Smooth Rolling Surface:Rails muaj qhov txuas ntxiv, qis - ua haujlwm saum npoo rau lub log, tso cai rau kev sib tw, ua haujlwm tau zoo, thiab txav nrawm.
- Cov Qauv Txheej Txheem:Lawv tsim cov txheej txheem tseem ceeb ntawm txoj kev khiav, ruaj ntseg los ntawm fastenings rau cov neeg pw tsaug zog, tsim kom muaj lub zog ruaj khov.
- Signaling Conductor:Rails ua cov cim hluav taws xob rau cov kab hluav taws xob khiav, uas kuaj pom lub tsheb ciav hlau, qhov chaw, thiab kev txav mus los, tseem ceeb heev rau kev nyab xeeb.

Yuav ua li cas xaiv ib lub tsheb ciav hlau nrog tus qauv tsim nyog?
Txhawm rau xaiv txoj cai steel rail qauv, ntsuas koj qhov project txoj kev tsheb khiav (ceev, tonnage, qag load), ib puag ncig, thiab pob nyiaj siv, tom qab ntawd muab cov qauv no rau cov qauv tshwj xeeb (AREMA, EN, UIC), xav txog qhov hnyav (kg / m), profile (piv txwv li, 60E1), thiab qib (piv txwv li, R350HT rau hnyav -cov qauv kev cai), R26 kev nyab xeeb thiab kev tsim kho hauv zos. kev ua tau zoo.
Yam tseem ceeb uas yuav tau xav txog
- Tsheb thauj mus los & Load: Siab-ceev (Ntau dua lossis sib npaug li 250km / h) lossis hnyav-haul (Ntau dua lossis sib npaug ntawm 25t qag load) xav tau cov tsheb ciav hlau muaj zog xws li EN 60E1/R350HT; Lub teeb loads tuaj yeem siv cov hlua sib dua (piv txwv li, 30kg / m).
- Ceev: Kev nrawm dua xav tau kev sib tw, muaj zog dua rau kev caij tsheb zoo dua thiab qaug zog, feem ntau lub taub hau- tawv.
- Ib puag ncig: thaj chaw ntug hiav txwv xav tau corrosion-cov ciav hlau tiv taus; Kev nyab xeeb hnyav tuaj yeem nyiam cov pa roj carbon steel tshaj qee qhov siab - lub zog alloys.
- Daim ntawv thov: Mainlines (R260, R350HT), tsheb thauj mus los hauv nroog (49E1 / R260, grooved rails), mining (R370CrHT) muaj cov kev xav tau sib txawv.
- Cov Qauv: Ua raws li cov qauv lees paub xws li EN (European), AREMA (North American), UIC (International), lossis GB (Suav).
