Lub pas dej tam, raws li tseem ceeb rau kev tsim kho vaj tsev zoo nkauj, yuav tsum yog tsim kom muaj ntau lub zog sab nraud, suav nrog dej siab, thiab cov kev ua txhaum cai ntxias. Cov tub rog sab nraud yuav tsum muaj nyob rau qhov kev nyab xeeb thiab ruaj khov ntawm cov qauv ua kom zoo nkauj, thiab yog li ntawd, thaum xaiv cov kev ua si ntawm cov pas dej tauv kom ntseeg tau tias nws cov haujlwm ntev.
Feem ntau, steel fibers rau dams muaj cov cuab yeej zoo dua thiab kav rau kev xaiv khaub ncaws zoo tshaj plaws thiab tshuaj tiv thaiv kev tiv thaiv khaub ncaws. Qhov siab dua lub zog ntawm cov hlau steel, ntau qhov tseem ceeb ntawm cov khoom muaj peev xwm, thiab tiv thaiv kev puas tsuaj rau kev puas tsuaj vim dej ntws los yog lwm yam. High-zog steel fibers tsis tsuas yog txhim kho lub tensile lub zog ntawm cov pob zeb ua kom tshwm sim los ntawm av qeeg lossis lwm yam kev siv hluav taws xob.
Ib qho ntxiv, lub pas dej yog feem ntau nyob ze rau cov dej hauv lub cev, ua rau muaj kev cuam tshuam rau kev yaig los ntawm dej ntws, av noo, thiab tshuaj lom neeg. Yog li ntawd, txoj kev xeb tawm tsam ntawm cov steel fibers rau dams yog qhov tseem ceeb yog qhov tseem ceeb yog qhov kev xaiv lawv. Txij li thaum lub pas dej uas muaj tas li rau cov chaw noo noo, cov corrosion tsis kam ntawm cov steel fibers ncaj qha cuam tshuam lub pas dej tauv. Stainless hlau fibers thiab alloy steel fibers feem ntau nthuav tawm cov siab corrosion, ua rau cov kev xaiv oxidation tsis kam, ua rau kev xaiv zoo rau kev siv noo noo. Cov fibers tau tiv thaiv kev puas tsuaj los ntawm kev xeb ntawm cov dej, ntsev, lossis lwm yam tshuaj, uas yog qhov txuas tau lub neej ntawm cov qauv dam.
Thaum xaiv cov hlau steel rau lub pas dej dams, nws tseem ceeb kom cov kev xaiv raws li cov kev thov kev thov tshwj xeeb. Piv txwv li, qee thaj chaw ntawm lub pas dej tam tej zaum yuav tau tiv thaiv dej siab thiab ntxhov siab ntau dua thiab qhov loj me ntawm cov phaj loj dua. Nyob rau hauv cov rooj plaub no, high-zog, ntev dua steel fibers tuaj yeem siv rau kev txhawb nqa. Cov sib zog ntev dua thiab txhim kho lub zog tsis kam thiab ua kom tiv thaiv lub pas pob zeb ua kom tawg, tiv thaiv lub pas dej tauv vim tias muaj kev sib tsoo ntev dhau los. Rau cov cheeb tsam uas yuav tsum tau ua kom zoo dua ntawm kev tswj hwm cov tshuaj tua hluav taws xob, cov nplais steel nrog cov feem me me thiab cov kev faib tawm cov kev faib tawm me me tej zaum yuav raug xaiv. Zoo-lub taub hlau cov fibers muab ib qho loj tshwj xeeb thaj chaw, txhim kho nws cov kev cuam tshuam, txhim kho cov dej sib txawv, thiab txo cov dej sib txawv ntawm cov qauv kab dam.
Hauv kev xaus, xaiv cov fibers tsim nyog yog qhov tseem ceeb rau cov qauv tsim thiab kev tsim kho cov pas dej tauv. Los ntawm kev xav txog ntau yam xws li lub zog, loj, kev tiv thaiv zoo tuaj yeem ua tau zoo, thiab kev ruaj ntseg thoob plaws hauv nws lub neej, txawm tias nyob rau ib puag ncig ib puag ncig thiab kev ncua sij hawm siv.
