Txoj kev tsheb ciav hlauyog ib qho tseem ceeb ntawm txoj kev tsheb ciav hlau, thiab nws txoj haujlwm yog coj lub tsheb ciav hlau lub log mus rau pem hauv ntej los ntawm kev tiv thaiv lub zog loj ntawm lub log. Steel rail yuav tsum muab du, ruaj khov thiab nruam dov nto rau lub tsheb ciav hlau dhau lub log. Nyob rau hauv hluav taws xob railway los yog tsis siv neeg thaiv seem, railway khiav kuj yuav siv tau raws li ib tug khiav Circuit Court.
Dab tsi yog hom rails?
Txoj kev tsheb ciav hlau feem ntau yog cais los ntawm lawv tus ntoo khaub lig- ntu rau hauvPav ca-Kub (Vignole) Rails, feem ntau, nrog lub hauv paus tiaj tus rau ncaj qha fastening;Bull-Headed Rails, thicker ntawm lub taub hau rau lub zog, siv nyob rau hauv cov ntsiab lus / hloov; thiab laus duaOb -Headed Rails, symmetrical rau reversible siv, tam sim no tsis tshua muaj, nrog tshwj xeeb hom xws li Grooved Rails rau trams thiab Check Rails rau nkhaus kuj muaj.

Lub luag haujlwm ntawm steel rail yog dab tsi?
Lub luag haujlwm tseem ceeb ntawm steel rails yog muab kev sib tw, tsis tu ncua, thiab qis - kev sib txhuam ntawm lub tsheb ciav hlau log, coj lawv kom nyab xeeb raws txoj hauv kev tshwj xeeb thaum thauj cov khoom hnyav thiab xa cov quab yuam mus rau lub txaj khiav (sleepers / ballast). Tshaj li kev taw qhia thiab kev txhawb nqa, cov tsheb ciav hlau kuj ua raws li cov khoom siv hluav taws xob rau cov khoom siv hluav taws xob hauv kev tsheb ciav hlau hluav taws xob thiab yog qhov tseem ceeb rau kev nyab xeeb, ua haujlwm tau zoo, thiab ruaj khov tsheb ciav hlau.
Lub luag haujlwm tseem ceeb:
- Kev taw qhia & kev txhawb nqa: Lawv tsim cov kab sib txuas, coj cov tsheb ciav hlau thiab txhawb nqa qhov hnyav hnyav ntawm locomotives thiab carriages.
- Load Transfer: Rails nqus ntsug siab, cuam tshuam, thiab lub zog sab nraud ntawm lub log thiab faib rau cov neeg pw tsaug zog, ballast, thiab subgrade.
- Low Friction Surface: Cov hlau- ntawm- steel tiv thaiv tsim cov dov tsis zoo, ua rau lub zog- txav tau zoo.
- Kev Qhia Teeb Meem: Hauv ntau lub tshuab, rails nqa hluav taws xob teeb liab los kuaj xyuas lub tsheb ciav hlau, qhov chaw, thiab kev txav mus los, ua kom muaj kev nyab xeeb.
- Stability & Durability: Lawv tsim lub hauv paus ruaj khov, tiv thaiv kev vibrations thiab muab lub sijhawm ntev - taug qab rau siab - nrawm thiab hnyav - tsheb thauj mus los.
Txij xyoo 2008,GNEE RAILtau muab steel rails ntawm ntau qib sib txawv rau ntau tshaj 18 xyoo, steel rails los ntawm GNEE yog heev recommened nyob rau hauv Tuam Tshoj thiab txawv teb chaws.Wtih txiav ntug cov cuab yeej, GNEE ua tau zoo steel rails raws li cov kev cai ntawm feem ntau lub teb chaws. Standard rail, lub taub hau hardened rail, hnyav rail, lub teeb rail, crane rail thiab lwm yam yog tag nrho cov muaj nyob ntawm no, raws li ib tug ntawm cov Tuam Tshoj lub ntsiab rail tsum, GNEE RAIL tau ua hauj lwm rau muab kev lag luam ntsuab railway khoom thoob plaws lub ntiaj teb no.
