Hom Lub Pob Zeb Sleepers

Lub tsheb ciav hlau pw tsaug zog tuaj yeem tshwm sim tsis zoo, tab sis nws txoj haujlwm tseem ceeb. Lub luag haujlwm tseem ceeb ntawm tus neeg pw tsaug zog yog txhawb nqa cov ntsia hlau thaum tuav lawv txoj haujlwm thiab hloov lub siab loj ntawm cov ntsia hlau mus rau lub txaj khiav. Yog li ntawd, cov neeg pw tsaug zog yuav tsum muaj qee qhov kev hloov pauv thiab elasticity - nyuaj heev tsis haum, thiab muag heev kuj tsis zoo tagnrho. Thaum lub tsheb ciav hlau hla, tus neeg pw tsaug zog tuaj yeem deform me ntsis kom cushion lub siab, tab sis nws yuav tsum rov qab mus rau nws qhov qub zoo li ntau li ntau tau tom qab lub tsheb ciav hlau hla.

Peb GNEE txoj kev tsheb ciav hlau tshwj xeeb hauv kev tsim, tsim khoom, thiab muag khoom ntawm hom kev tsheb ciav hlau pw tsaug zog, suav nrog cov pob zeb sib xyaw, cov pob zeb muaj zog, cov ntoo pw tsaug zog. Peb cov neeg pw tsaug zog zoo sib xws hauv qhov loj, elastic, thiab ruaj khov. Ua nrog chav kho thiab molding ib zaug, lawv muaj qhov chaw du thiab muaj zog, ntxiv dag zog sab hauv nrog steel rods. Lawv yog cov ruaj, huab cua-resistant, thiab corrosion-resistant, ua kom lub neej ntev. Kev cai tsim muaj. Tiv tauj peb kom paub meej ntxiv.

1. Railway sleepers feem ntau yog cais raws li lawv daim ntawv thov: cov pw tsaug zog tsis tu ncua, hloov pw tsaug zog, thiab tus choj pw tsaug zog. Cov neeg pw tsaug zog tsis tu ncua yog siv rau cov qauv kev taug qab, cov neeg pw tsaug zog hloov pauv tau siv rau hauv kev hloov tsheb ciav hlau, thiab cov neeg pw tsaug zog yog siv rau ntawm txoj kev tsheb ciav hlau. Qhov sib txawv tseem ceeb ntawm lawv yog lawv qhov ntev thiab txoj haujlwm uas lawv txhawb nqa cov ntsia hlau.

2. Traditional railway sleepers tuaj yeem muab faib ua wood sleepers, steel sleepers, thiab prestressed reinforced concrete sleepers, raws li cov ntaub ntawv siv.

• Cov ntoo pw tsaug zog tau siv sijhawm ntev, nrog ntau dua 2.5 billion ntsia thoob ntiaj teb. Lawv yog cov elastic heev, yooj yim rau txheej txheem, thiab yooj yim rau nruab. Txawm li cas los xij, lawv yooj yim rau kev lwj, thiab kev tswj xyuas cov duab geometry dhau sijhawm tuaj yeem nyuaj.
• Steel sleepers, qhia nyob rau hauv 1880s, yog lub teeb yuag thiab muaj lub neej ntev kev pab cuam. Txawm li cas los xij, lawv raug kev txom nyem los ntawm kev rwb thaiv tsev tsis zoo, kev co siab, thiab lub suab nrov tseem ceeb.
• Tus thawj prestressed reinforced qhob pw tsaug zog yog qhia nyob rau hauv 1943, thiab nws high longitudinal thiab lateral resistance, raws li zoo raws li nws ntev lifespan, ua rau nws dav saws. Txawm hais tias cov txiaj ntsig zoo no, nws hnyav thiab tsis tshua muaj elasticity.
• Hauv kev teb rau cov kev txwv ntawm cov ntaub ntawv ib txwm muaj, kev tshawb fawb rau hauv cov khoom sib xyaw ua ke tau loj hlob. Cov neeg pw tsaug zog no txhawm rau txhim kho kev ua haujlwm ntev, txo cov nqi tsim khoom, thiab txo qhov cuam tshuam ib puag ncig thaum tsim khoom, thaum kawg muab cov kev daws teeb meem zoo dua rau cov kev tsheb ciav hlau niaj hnub no.
