Kev nce qib hauv Railroad Infrastructure Technology
Txawm hais tias qhov zoo li ntawm txoj kev tsheb ciav hlau yuav zoo li tsis muaj kev hloov pauv hauv ib puas xyoo dhau los, kev txhim kho thev naus laus zis tau txhim kho lub zog, kev nyab xeeb, thiab kev ntseeg siab ntawm txoj kev tsheb ciav hlau. Ib txoj kev tsheb ciav hlau raug muaj xws li ob qho tib si steel rails teem rau ntawm qhov sib nrug deb, hu ua qhov ntsuas. Cov kev tsheb ciav hlau no txuas nrog txoj kev tsheb ciav hlau, uas tuaj yeem tsim los ntawm ntau yam ntaub ntawv xws li ntoo, pob zeb, lossis cov khoom sib xyaw. Cov hlua khi tau ruaj ntseg rau cov ntsia hlau uas siv cov hlua khi, bolts, lossis cov clip tshwj xeeb, nyob ntawm seb hom khi siv. Hauv qab cov kev sib raug zoo yog cov ballast, feem ntau muaj cov pob zeb crushed los yog gravel, uas ua hauj lwm los muab lub hauv paus ruaj khov rau kev khiav thiab faib cov tsheb ciav hlau hla.
Cov Cheebtsam tseem ceeb ntawm Railroad Infrastructure:
Railroad Track: Parallel steel rails nteg rau saum cov ties.
Rail: steel tuav muab tso rau qhov kawg rau hauv ob kab sib luag.
Spike: Cov khoom siv hlau siv los txuas cov hlua khi rau lub tsheb ciav hlau.
Tie: Ntoo los yog qhob khoom nyob rau hauv perpendicular mus rau hauv qab cov rails.
Tie Phaj: Hlau phaj uas txhawb nqa thiab ruaj ntseg rau txoj hlua khi.
Ballast: Crushed pob zeb los yog gravel txheej hauv qab txoj hlua khi, ua haujlwm raws li lub hauv paus.
Kev nce qib hauv kev tsim cov hlau tau ua rau cov hlau zoo dua siv rau kev tsheb ciav hlau, ua kom lawv lub neej ntev mus rau qhov nruab nrab ntawm 50-60 xyoo. Lub neej ntev ntawm txoj kev tsheb ciav hlau nyob ntawm cov khoom xws li qhov ntim ntawm cov khoom thauj txhua xyoo thiab lwm yam kev mob ib puag ncig. Cov tuam txhab tsheb ciav hlau ntiav cov cuab yeej tshwj xeeb, suav nrog cov tsheb khiav tsheb thiab cov tsheb ciav hlau tsis xws luag, nrog rau kev kuaj pom, los saib xyuas cov xwm txheej. Cov thev naus laus zis siv laser ntsuas kom paub txog kev hnav thiab ua kom muaj peev xwm sib kho kom ntseeg tau tias muaj kev nyab xeeb thiab kev ua haujlwm rail.
