Qhov txawv ntawm Hauv qab -Sleeper Pads thiab Hauv qab -Ballast Mats yog dab tsi?
Hauv kev nrhiav kev caij tsheb zoo dua thiab cov nroog nyob ntsiag to, niaj hnub kev tsheb ciav hlau engineering siv ntau txheej txheej elastic nyob rau hauv txoj kev taug qab superstructure. Ob ntawm cov qib siab tshaj plaws tab sis nquag tsis meej pem yog covHauv qab -Sleeper Pad(USP) thiabHauv qab -Ballast Mat(UBM). Thaum ob leeg ua haujlwm los qhia txog elasticity rau hauv lub cev, lawv ua haujlwm ntawm ntau qib sib txawv ntawm txoj kab "sandwich." Thawj qhov sib txawv yog nyob rau hauv lawv txoj hauj lwm txheeb ze rau lub ballast: ib tug zaum saum lub ballast, thaum lwm tus nyob hauv qab nws.
1. Qhov chaw thiab kev teeb tsa Logic
Qhov sib txawv tshaj plaws yog kev tso lub cev. Hauv qab -Sleeper Pad yog ib feem tseem ceeb ntawm chav pw tsaug zog. Nws yog bonded ncaj qha mus rau hauv qab nto ntawm lub pob zeb sleeper (kiv). Yog li ntawd, nws txav dynamically nrog lub sleeper thiab zaum ncaj qha rau saum lub pob zeb crushed ballast.
Hauv qhov sib piv, Hauv qab -Ballast Mat yog txheej txheej zoo li qub. Nws yog ib tug nruam elastic lev (muab nyob rau hauv yob los yog loj nplooj ntawv) uas yog nteg ncaj qha mus rau lub subgrade, qhov hauv pem teb, los yog choj lawj. Tom qab ntawd lub ballast yog poured rau saum lub lev. Qhov tseem ceeb, USP ua raws li kev tiv thaiv ib leeg rau cov neeg pw tsaug zog, thaum UBM ua lub hauv paus ntaub pua plag rau tag nrho lub txaj.
2. Lub Hom Phiaj Ua Haujlwm: Kev Saib Xyuas vs
Thaum ob leeg txo kev vibration, lawv cov hom phiaj engineering sib txawv. Lub luag haujlwm tseem ceeb ntawm Railway Sleeper Pads (USP) yog txhawm rau txhim kho lub voj voog khiav haujlwm. Los ntawm kev ua kom thaj chaw sib cuag ntawm cov neeg pw tsaug zog thiab cov pob zeb ballast, USPs faib cov khoom sib npaug ntau dua, txo cov pob zeb atrition (pulverization) thiab txuas ntxiv lub sijhawm ntawm kev khiav tamping.
Ntawm qhov tod tes, Hauv qab -Ballast Mats (UBM) feem ntau yog siv rau kev tiv thaiv ib puag ncig thiab kev tsim qauv. Lawv yog cov kev daws teeb meem zoo tshaj plaws rau kev sib cais hauv av- ua suab nrov thiab kev co, tiv thaiv lawv los ntawm kev mus rau hauv cov tsev nyob ze. Tsis tas li ntawd, lawv yog cov qauv kev qhia tshwj xeeb rau kev tsheb ciav hlau txuas hniav los tiv thaiv cov pob zeb ua pob zeb los ntawm kev puas tsuaj los ntawm cov pob zeb abrasive.
