1. Yuav ua li cas spikes ua nyob rau hauv cov av qeeg?
Seismic adaptations:
Siab dua ductility steels (elongation >18%)
Tapered shanksrau lub zog nqus
Txo qhov sib nrug(txhua qhov khi hauv Zone 4+)
Nyiv siv U-zoo li tus spikes hauv Shinkansen qhov.
2. Dab tsi ua rau lub qhov taub elongation?
Progressive hnav los ntawm:
Spike kev vibrationnyob rau hauv dynamic loads
Ntoo fiber ntau crushingnyob rau hauv ntub dej
Dej khov expansionnyob rau hauv huab cua txias
Qhov ntau tshaj 20% oversize yuav tsum khi ntsaws lossis hloov.
3. Yuav ua li cas spikes yoog rau cov suab puam lem?
Kev hloov kho muaj xws li:
Stainless hlau spikes(316L qib)
Sand shieldstshaj spike taub hau
Epoxy-coated shanks
Hmo ntuj-tsuas yog kev teeb tsakom tsis txhob thermal distortion
4. Dab tsi yog qhov acoustic kos npe ntawm lub xoob spike?
Loose spikes tsim:
450-600Hz suab nrovthaum ntaus
75dB cuam tshuam lub suab nrovvs 60dB rau nruj spikes
Acoustic detectors ntawm lub tsheb tshuaj ntsuam xyuas 95% ntawm xoob spikes.
5. Yuav ua li cas spikes cuam tshuam nrog kev kho ntoo?
Kev kho Creosote cuam tshuam:
Tshem tawm tsis kam(+15% vs tsis kho)
Corrosion tus nqi(ua kom nrawm los ntawm 20%)
Installation torque(yuav tsum tau 10% siab zog)
Copper naphthenate kev kho mob yog qhov zoo tshaj -friendlier.
