Railway sleepers Qhov zoo
Railway sleepers, tseem hu ua railroad ties los yog crossties, ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa thiab kev ruaj ntseg railway lem. Lawv qhov zoo muaj xws li:
Txhawb nqa Rails:
Cov neeg pw tsaug zog muab qhov chaw ruaj khov thiab theem rau cov kev tsheb ciav hlau. Lawv faib cov khoom thauj ntawm cov tsheb ciav hlau hla, pab tiv thaiv cov tsheb ciav hlau los ntawm kev poob rau hauv av.
Kev ruaj ntseg Rail Alignment:
Cov neeg pw tsaug zog pab tswj qhov kev sib raug zoo thiab ntsuas (qhov deb ntawm txoj kev tsheb ciav hlau) ntawm txoj kev tsheb ciav hlau, ua kom cov tsheb ciav hlau du thiab nyab xeeb.
Absorbing vibrations:
Cov neeg pw tsaug zog nqus cov kev vibrations tsim los ntawm kev txav tsheb ciav hlau, ua rau lub caij yooj yim dua thiab yooj yim dua rau cov neeg caij tsheb thiab txo qis kev hnav ntawm txoj kev tsheb ciav hlau.
Tiv thaiv Rail Creep:
Rail sleepers pab tiv thaiv "rail creep," uas yog maj mam txav ntawm txoj hlua hla lub sijhawm. Txhim kho cov neeg pw tsaug zog txhim kho cov ntsia hlau rau hauv qhov chaw, tswj kev taug qab kev ruaj ntseg.
Distributing Loads:
Cov neeg pw tsaug zog faib cov khoom thauj los ntawm kev hla cov tsheb ciav hlau mus rau hauv qab ballast, muab qhov dav thiab ntau dua los txhawb qhov chaw kom tsis txhob muaj kev ntxhov siab ntau dhau ntawm cov khoom siv.
