Nyob rau lub sijhawm thaum ntxov ntawm Indian Railway, ntoo yog tib yam khoom ntawm kev ua kom tsaug zog hauv ntiaj teb. Nrog rau txoj kev loj hlob ntawm cov cuab yeej siv cuab yeej cuab tam nyob rau hauv lub xyoo pua puv 19, cov cement pob zeb tau tsim nws qhov chaw ua ntau yam khoom siv hauv tsev thiab tuaj yeem siv tau raws li qhov yuav tsum tau ua ntawm txoj kev tsheb ciav hlau. Pob zeb pw tsaug zog tau tsim los ntawm Kev Tshawb Fawb Tsim thiab Cov Qauv Txheej Txheem (RDSO) tis ntawm Indian Railway.
BG pw tsaug zog
Pob zeb pw tsaug zog muaj ntau yam: pre-stressed qhob pw tsaug zog, pre-tension qhob pw tsaug zog, post-tension qhob sleeper thiab ob-thaiv qhob pw tsaug zog. Ntau hom pob zeb pw tsaug zog yog tsim los ntawm Indian Railway.

Qhob rail sleepers
Cov ntoo ntoo ntoo muaj ntau yam zoo xws li kev ua neej ntev, kev ruaj ntseg siab, kev saib xyuas me me, kev puas tsuaj tsawg thiab qis qis. Lawv tau dav siv nyob rau hauv kev kub ceev railway thiab kev ruaj ntseg yog ntau dua li ntoo sleepers. Ntau lub tebchaws tau xaiv cov neeg pw tsaug zog los tsim kev kub ceev cov neeg caij tsheb. Thaum cov pob zeb pw tsaug zog tseem muaj ntau yam tsis zoo xws li hnyav hnyav, nyuaj rau kev thauj mus los thiab kev txwv ib puag ncig. Lawv tsis haum rau lub ntiaj teb khov, hnyav heev hauv cheeb tsam thiab tsis khoom ntawm cov pob zeb hauv av.
Qhov zoo ntawm pob zeb rail sleepers
1. Muab siab dua longitudinal thiab transverse stability
2. Ib qho yooj yim los tswj kev ntsuas, hla qib thiab kev sib tw
3. Haum rau cov txheej txheem niaj hnub ntawm kev saib xyuas
4. Nws tuaj yeem siv rau hauv cov kab hluav taws xob hauv cheeb tsam
5. Lub neej ntev dua (40-50 xyoo) tso cai rau kev rov ua dua tshiab ntawm kev tsheb ciav hlau thiab pw tsaug zog ua ke
6. Haum rau kev tsim khoom loj nrog cov khoom siv hauv zos
7. Tsis raug rau (corrosion, hluav taws kub txaus ntshai thiab kab tsuag tua)
Qhov tsis zoo
1. Hnyav los tuav
2. Taug kev nteg xav tau kev siv tshuab
3. Kev puas tsuaj hnyav thaum lub sij hawm derailment
4. Tsis muaj nqi seem
