Plaub hom kev tsheb ciav hlau yog dab tsi?
Jan 15, 2026
Railway Trackyog ib qho qauv tsim los ntawm steel rails, sleepers, txuas qhov chaw, taug kev txaj, turnouts thiab lwm yam khoom siv ntxiv. Nws bears txawv ntsug, kab rov tav thiab longitudinal static thiab dynamic loads. Lub load yog kis los ntawm cov ntsia hlau mus rau subgrade los ntawm cov sleepers thiab lub txaj khiav. Nws ua lub luag haujlwm tseem ceeb hauv kev thauj mus los hauv kev tsheb ciav hlau.
Plaub hom kev tsheb ciav hlau
Dab tsi yog Ballasted Track?
Lub ballasted khiav yog hom kev tsheb ciav hlau uas muaj ntau tshaj plaws, muaj cov ntsia hlau, pw tsaug zog, fasteners, thiab lub txaj ntawm cov pob zeb crushed hu ua ballast. Ballast faib cov khoom thauj, muab cov dej ntws tawm, thiab tswj kev sib tw khiav.
Dab tsi yog Ballastless (Slab) Track?
Slab lem siv pob zeb los yog asphalt slabs es tsis txhob ballast. Rails yog fastened ncaj qha mus rau lub slab, muab siab stability thiab tsis tshua muaj txij nkawm. Cov kab no zoo tagnrho rau kev hla nroog, siab - tsheb ciav hlau ceev, qhov av, thiab txuas hniav.
Lub Teeb Rail / Tram Track yog dab tsi?
Lub teeb rail rail yog tsim los rau hauv nroog tsheb thauj mus los xws li trams thiab LRT (Light Rail Transit). Lawv yog cov sib dua, feem ntau nyob rau hauv txoj kev lossis pavements, thiab tso cai rau kev sib xyaw nrog cov tsheb thiab cov neeg taug kev.
Dab tsi yog Crane lossis Industrial Track?
Crane rails yog hnyav-cov dej num tsim los rau kev lag luam ib puag ncig xws li steel mills, ports, lossis warehouses. Lawv nqa lub log siab thiab tiv thaiv sab nraud thiab cuam tshuam los ntawm cranes.
Lub luag haujlwm ntawm steel rail nyob rau hauv txoj kev tsheb ciav hlau yog dab tsi?
Lub tsheb ciav hlau steel yog lub hauv paus thauj khoom -cov kabmob ntawm txoj kev tsheb ciav hlau, lub luag haujlwm rau kev cob qhia cov tsheb ciav hlau thiab xa cov khoom thauj los ntawm lub log mus rau lub hauv paus kev txhawb nqa. Nws ua kom muaj kev sib tw, nyab xeeb, thiab muaj txiaj ntsig kev txav mus los ntawm txoj kev tsheb ciav hlau, txawm hais tias nyob rau hauv cov neeg caij tsheb thauj mus los, cov chaw thauj khoom thauj, lossis kev siv hauv kev lag luam.
Steel rails muab ib tug nruam khiav nto rau tsheb ciav hlau log, txo dov kuj thiab hnav. Lawv qhov profile tsim- suav nrog lub taub hau tsheb ciav hlau, lub vev xaib, thiab ko taw- xyuas kom meej:
- Lub taub hau resists hnav thiab dov kev sib cuag qaug zog.
- Lub vev xaib hloov txoj kab ntsug thiab sab nraud mus rau lub hauv paus kev tsheb nqaj hlau.
- Cov ko taw (hauv paus) faib cov khoom thauj mus rau cov neeg pw tsaug zog thiab lub kaw lus fastening, tswj kev ruaj ntseg ntawm sab nraud.
GNEE RAILmuaj nyob rau hauv kev tsim steel rails ntawm ntau yam qauv siv nyob rau hauv coal mining, lub ntsiab railway kab, factories, cranes, thiab lwm yam. Muaj lub teeb steel rails, hnyav steel rails, crane steel rails, thiab tshaj hnyav steel rail.
