Dab tsi yog qhov chaw ntawm txoj kev tsheb ciav hlau hu ua?
Jan 15, 2026
Cov hlau rail, tseem hu ua kev tsheb ciav hlau, kev tsheb ciav hlau rail, yog siv los coj lub tsheb ciav hlau log mus deb, los ntawm kev tiv thaiv kev ntxhov siab los ntawm lub log thaum lub tsheb ciav hlau hla, thiab hloov mus rau cov hlua khi thiab. Txoj kev tsheb ciav hlau yuav tsum muab du thiab nruam dov nto nrog yam tsawg kawg nkaus.
Dab tsi yog qhov chaw ntawm txoj kev tsheb ciav hlau hu ua?
Ib txoj kev tsheb ciav hlau yog ntau tshaj li cov tsheb ciav hlau; nws yog ib tug ua tiav system tsim kom muaj kev nyab xeeb coj tsheb ciav hlau, faib loads, thiab muab stability. Cov khoom tseem ceeb ntawm txoj kev tsheb ciav hlau muaj xws li cov tsheb ciav hlau, cov neeg pw tsaug zog (cov hlua khi), cov hlua khi, ballast, thiab subgrade. Txhua qhov chaw muaj cov haujlwm tshwj xeeb, ua haujlwm ua ke kom muaj kev nyab xeeb thiab ua haujlwm tau zoo.
Covtsheb ciav hlauyog longitudinal steel tivthaiv uas ncaj qha mus rau lub tsheb ciav hlau log. Niaj hnub nimno steel rails muaj peb yam tseem ceeb:
| Rail Part | Muaj nuj nqi | Yam khoom siv |
|---|---|---|
| Rail taub hau | Kev sib cuag ncaj qha nrog lub tsheb ciav hlau log; resists hnav thiab dov kev qaug zog | Siab - carbon steel, U71Mn, R350HT |
| Rail Web | Txuas lub taub hau thiab ko taw; hloov lub zog ntsug thiab sab nraud | Alloy los yog pearlitic steel |
| Rail Foot (Pib) | Distributes load rau sleepers thiab fastening system; muab lateral stability | Thaum tshav kub kub- kho steel |
Tag nrho cov kev tsheb ciav hlau niaj hnub tam sim no yog ua los ntawm cov hlau kub kub ntawm cov ntoo khaub lig tshwj xeeb - ntu (profile) uas kwv yees li kuv - nqaj tab sis yog asymmetric txog kab rov tav ---paj hauv qab, yog li ntawd tuaj yeem so ncaj qha rau ntawm cov hlua khi thiab bullhead rails zoo. Ib txoj kev tsheb ciav hlau yog tsim los ntawm peb feem ntawm txoj kev tsheb ciav hlau Lub Taub Hau, Web thiab Ko Taw, thiab tag nrho cov ntu ntu ntu yog ib txwm ua los ntawm kev tsheb ciav hlau qhov siab (A), Ko taw dav (B) thiab Lub taub hau dav (C). Ua ke nrog lub Web thickness(t), 4 qhov ntau thiab tsawg yog tag nrho qhov ntev rau kev faib cov tsheb ciav hlau.
Dab tsi yog Ballast thiab Subgrade?
- Ballast:Crushed pob zeb los yog aggregate txheej uas txhawb nqa cov neeg pw tsaug zog, tso cai rau cov dej ntws tawm, thiab tswj kev sib tw khiav.
- Subgrade:Lub hauv paus av hauv qab txoj kab uas dais tag nrho cov loads pauv los ntawm kev tsheb ciav hlau thiab cov pw tsaug zog. Kev cog lus kom raug thiab kev npaj yog qhov tseem ceeb rau kev taug qab mus ntev.
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.
