Vim li cas Under Sleeper Pads (USP) siv hauv kev tsheb ciav hlau?
A rail ncoo, tseem hu ua rail roj hmab phaj, yog tsim los ntawm lub tsheb ciav hlau khi phaj thiab ko taw ntawm txoj kev tsheb ciav hlau, ua los ntawm elastic polyurethane lev, uas yog interposed ntawm steel rails thiab khi sleepers los tiv thaiv lub sleeper saum ntawm hnav thiab cuam tshuam. Nws txoj kev nruj nruj yog siv los ua kom lub elasticity ntawm lub superstructure ntawm lub ballast thiab txo kev poob siab thiab kev vibration hauv txoj kev tsheb ciav hlau.
Nyob rau hauv ib txwm hierarchy ntawm railway superstructure Cheebtsam, ua kom pom tseeb tau muab tso rau hauv lub Rail Pad nyob nruab nrab ntawm lub steel rail thiab lub sleeper. Txawm li cas los xij, kev hloov pauv thev naus laus zis tseem ceeb tshwm sim hauv qab tus neeg pw tsaug zog nws tus kheej. CovHauv qab Sleeper Pad(USP), ib txheej elastic txuas rau hauv qab ntawm cov pob zeb pw tsaug zog, tau dhau los ua tus qauv tshwj xeeb rau High-Speed Rail thiab Heavy Haul networks thoob ntiaj teb.
Transforming Ballast Interaction: Los ntawm Cov Ntsiab Lus rau Nto
Qhov tseem ceeb ntawm kev sib tw hauv ballasted lem yog kev sib cuam tshuam ntawm ob yam khoom tsis zoo: lub pob zeb pw tsaug zog thiab cov pob zeb crushed. Yog tsis muaj lub ncoo, kev sib cuag tsuas yog tshwm sim ntawm cov ntsiab lus ntse ntawm cov pob zeb, tsim kom muaj kev ntxhov siab heev. Nyob rau hauv dynamic loading, qhov no ua rau lub ballast pulverize thiab degrade, ua rau taug qab kev sib haum xeeb.
Lub Under Sleeper Pad daws qhov no los ntawm kev muab qhov cuam tshuam zoo. Ua los ntawm tshwj xeeb polyurethane los yog roj hmab tebchaw, cov Railway Sleeper Pads cia cov pob zeb ballast embed me ntsis rau hauv elastic txheej. Qhov no nce qhov chaw sib cuag los ntawm ib txwm 2-12% mus rau ntau dua 35%. Qhov "txoj kev pw tsaug zog" no ua rau txo qis kev sib cuag, tiv thaiv lub ballast los ntawm attrition thiab ncua sij hawm ntawm cov nqi taug qab tamping txij nkawm mus txog 50%.
Vibration Control thiab Stiffness Transition
Tshaj li kev tiv thaiv ballast, USPs yog cov cuab yeej siv hluav taws xob tseem ceeb rau kev tswj xyuas qhov nruj. Hauv "hloov chaw"-xws li qhov chaw taug kev txav ntawm tus choj lossis qhov mus rau hauv ib qho embankment- tam sim ntawd qhov kev hloov pauv ntawm qhov qis qis tuaj yeem ua rau kev taug qab geometry faults. Los ntawm kev txhim kho Ballast Mats lossis USPs nrog cov qib nruj sib txawv, cov kws ua haujlwm tuaj yeem tsim kom muaj kev sib hloov ntawm qhov tawv, tiv thaiv kev sib txawv. Tsis tas li ntawd, rau cov kab hauv nroog, cov ntaub qhwv no ua lub zog muaj zog ntawm kev sib cais, txo cov av- ua rau muaj suab nrov kis mus rau cov tsev nyob ze.
Bonding Technology ntawm GNEE RAIL
Qhov tseem ceeb ntawm kev vam meej rau USP yog nws daim ntawv cog lus rau lub pob zeb pw tsaug zog; delamination nyob rau hauv daim teb tsis yog ib qho kev xaiv. Ntawm GNEE RAIL, peb siv cov thev naus laus zis sib koom ua ke, suav nrog cov tshiab- kev sib txuas ua ke (qhov twg lub ncoo tau koom ua ke thaum pw tsaug zog casting) thiab tom qab- tawv adhesion. Peb cov khoom tau dhau los ua nruj nreem rub- tawm ntawm kev sim thiab qaug zog simulation kom ntseeg tau tias lawv muaj sia nyob ntawm kev tsheb ciav hlau hnyav. Txawm hais tias koj xav tau siab - cov tawv tawv tawv rau kev ruaj ntseg lossis cov ntaub mos muag rau kev co damping, GNEE RAIL muab cov kev daws teeb meem uas ua rau koj txoj kev ua tau zoo.
GNEE RAILMuaj ntau hom kev tsheb ciav hlau fasteners kom tau raws li cov neeg siv khoom xav tau, xws li Elastic Rail Clip thiab Clamp, Rail Screw Spike, Yas Dowel, High Tensile Track Bolt nrog txiv ntseej, Rail Base (Tie) Phaj, Rail Fish Phaj, Rail Lub xub pwg (Ntxig), Ntses Bolt, Railroad Rubber thiab EVA Pad, thiab lwm yam.
