Siv ntawm lub teeb ntsia hlau
Raws li ib qho tseem ceeb ntawm cov tsheb hla kev tsheb hla kev, lub teeb ntsia tau siv hauv ntau thaj teb. Txoj kev tsheb ciav hlau hnyav tsawg dua 30 kg ib lub ntsuas yog feem ntau yog ua rau cov roj ntsha lossis cov hlau tsis muaj zog, thiab yog tsim rau hauv cov qauv hla los ntawm kub dov. Cov qauv qauv no tsis tsuas yog ua kom muaj zog txhawb nqa lub zog ntawm txoj kev tsheb nqaj hlau, tab sis kuj yuav siv sijhawm rau kev lag luam ntawm cov khoom siv. Nyob rau hauv cov ntsiab lus ntawm cov khoom siv, tawm los dag zog ntawm Q235b thiab 55Q cov hlau mus txog 235 MPA thiab 355 MPa tau txaus los tiv thaiv kev thauj khoom txhua hnub.
Nroog Tram Systems Feem ntau siv 43kg / m kev ntsia, uas muaj tsheb ciav hlau siab ntawm 114 mm, uas tuaj yeem ua tau zoo lub tsheb yuag. Lub Henzhen Lauj Longhuata Tram Project siv UIC54 ntsia hlau. Nrog rau ib qho nruab nrab txhua hnub thauj neeg caij siab khiav ntawm 30, {5}}}}, cov ciav hlau qaim tsuas yog 0.15 mm / xyoo. Qhov chaw ua si scenic sightseeing tracks feem ntau siv 30kg / m ntsia hlau, thiab lawv cov haujlwm ntawm kev sib tw kom haum rau ntawm 15 mais hauv ib teev. Hainan Yanoda Rainforest Chaw Muag Khoom Tsw Siv Cov tsheb ciav hlau no ua tiav qhov kev xav tau tsawg kawg ntawm kev hloov hluav taws xob tsawg kawg ntawm 50 meters.
Nyob rau hauv kev thauj mus los ntawm kev thauj mus los, cov ntaub ntawv thov cov ntaub ntawv ntawm 38kg / m sib tw hauv kev tso tawm hauv lub tsheb hauv Sranexi tau tshaj tawm ntau tshaj 3 hli. Cov pob qij txha tsheb sib txuas nrog cov phaj ntses ntses, thiab cov ntsia liaj qhov rooj preload yog tswj tau li ntawm qhov kev sib koom ua ke yog tsawg dua 1 hli. Rau cov acidic mine ib puag ncig, cov nplaim dej yog kho nrog kub txhuas txau kom nce cov xeb tiv thaiv lub neej rau 2.3 zaug ntawm cov khoom siv dog dig.
Kev thauj mus los sab hauv ntawm cov nroj tsuag muaj kev lag luam feem ntau siv 24kg / m lub teeb ntsia hlau, thiab kev tsheb nqaj hlau ruaj khov yog tswj hwm ntawm Hb {1}}. Nyob rau hauv Shanghai Baostin raw khoom siv cov khoom siv, hom kev tsheb ciav hlau no txhawb nqa hluav taws xob tsheb nrog lub nra ntawm 50 tons. Lub pw tsaug zog spacing yog nce rau 400 mm, thiab kev tsheb ciav hlau hauv qab ntawm 1:40 kom muaj kev cuam tshuam nrog kev sib tw log tsheb. Lub kaw lus nrawm nrawm tau ua tiav cov kev hloov kho tau ntawm +15 hli rau txoj haujlwm khiav kom tau raws li cov txheej txheem hloov khoom.
