1. Cov kev tsheb ciav hlau puas tuaj yeem siv nrog cov ntoo pw tsaug zog uas tau kho nrog cov tshuaj tua kab mob?
Yog lawm, railway spikes yuav siv tau nrog preservative-kho ntoo sleepers (xws li, siab-kho nrog creosote). Txawm li cas los xij, cov tshuaj tua kab mob yuav cuam tshuam me ntsis rau qhov kev teeb tsa: cov ntoo kho mob nyuaj dua, yog li cov kab mob sib kis tuaj yeem xav tau ua ntej - tho qhov me me tsav kom tsis txhob khoov thaum hammering. Screw spikes feem ntau nyiam rau cov neeg pw tsaug zog kho mob, vim lawv cov qauv tsim ua kom nruj dua yam tsis muaj qhov sib cais ntoo. Cov tshuaj tua kab mob tsis ua rau cov kab mob phem - hloov pauv, nws txuas ntxiv rau tus neeg pw tsaug zog lub neej, uas ua rau lub sijhawm ntev ntawm qhov ua tau zoo los ntawm kev ua kom tus neeg tsaug zog ruaj khov.
2. Dab tsi yog qhov siab tshaj plaws rub - tawm quab yuam txoj kev tsheb ciav hlau tuaj yeem tiv taus?
Qhov siab tshaj plaws rub tawm - tawm quab yuam nyob ntawm hom spikes thiab cov khoom siv pw tsaug zog. Cov pa roj carbon hlau feem ntau hauv cov ntoo pw tuaj yeem tiv taus 5-8 kN ntawm rub- tawm dag zog. Alloy steel ntsia hlau spikes nyob rau hauv qhob pw tsaug zog tuaj yeem tuav 8-12 kN, ua tsaug rau lawv cov qauv tsim. Stainless hlau spikes nyob rau hauv composite sleepers muaj lub zog rub tawm ntawm 6-10 kN. Lub zog no raug sim thaum tsim khoom kom ntseeg tau tias spikes ua tau raws li cov qauv kev tsheb ciav hlau. Tshaj qhov quab yuam no (piv txwv li, los ntawm kev tsheb ciav hlau hnyav) yuav rub lub pob txha tawm ntawm tus neeg pw tsaug zog, ua rau muaj kev pheej hmoo ntawm kev tsis ruaj khov.
3. Txoj kev tsheb ciav hlau ua haujlwm li cas hauv thaj chaw uas muaj plua plav ntau zaus?
Plua plav cua daj cua dub nqa cov khoom zoo uas tuaj yeem ua rau lub tsheb ciav hlau tsis zoo ntawm qhov chaw, hnav los tiv thaiv- cov coatings coatings thiab ua rau cov hlau ua xeb. Dust can also accumulate in the gap between the spike and rail base, causing the spike to loosen over time. Hauv cov plua plav- cov cheeb tsam yooj yim, cov hlau alloy steel spikes nrog cov tawv tawv, hnav- cov chaw tiv taus yog siv. Cov neeg ua haujlwm ntxuav cov spikes tsis tu ncua nrog cua compressed los yog txhuam kom tshem tawm cov plua plav. Qee cov spikes kuj muaj du, qis - cov txheej txhuam uas tiv thaiv plua plav los ntawm kev lo. Cov kev ntsuas no pab spikes tiv thaiv kev puas tsuaj thiab tswj kev txhim kho thaum muaj cua daj cua dub.
4. Qhov txawv ntawm kub- dov thiab txias - dov railway spikes yog dab tsi?
Kub-rolled railway spikes yog tsim los ntawm cua sov hlau rods thiab shaping lawv nyob rau hauv kub kub, ua rau ib tug ntxhib nto thiab me ntsis inconsistent qhov ntev. Lawv qis dua - tus nqi thiab tsim nyog rau cov uas tsis yog - cov kab khiav tseem ceeb (piv txwv li, cov kab nyob deb nroog). Txias -rolled railway spikes yog zoo li nyob rau hauv chav tsev kub, tsim ib tug du, meej nto thiab zoo ib yam. Lawv muaj lub zog siab dua thiab zoo dua qhov ua tiav, ua rau lawv zoo tagnrho rau cov ntu tseem ceeb (xws li, siab - kev tsheb ciav hlau ceev lossis cov pob qij txha rail). Txias- dov spikes kuj tuav cov txheej txheem zoo dua, txhim kho corrosion kuj. Qhov kev xaiv nyob ntawm tus khiav txoj kev ua tau zoo thiab pob nyiaj siv.
5. Puas muaj peev xwm railway spikes raug ntsia rau hauv av khov?
Txhim kho kev tsheb ciav hlau spikes hauv av khov yog qhov nyuaj tab sis ua tau nrog kev ntsuas tshwj xeeb. Frozen av hardens ntoo sleepers, ua rau nws nyuaj rau rauj nyob rau hauv ntau spikes -pre-drilling pilot qhov nrog rhuab drills pab soften ntoo. Rau cov pob zeb pw tsaug zog, cov av khov tsis cuam tshuam cov ntsia hlau ntsia hlau loj npaum li cas, tab sis cov cuab yeej hluav taws xob (xws li cov ntsia hlau fais fab) yuav xav tau txias- huab cua hloov kho kom ua haujlwm zoo. Spikes lawv tus kheej tuaj yeem ua nkig hauv qhov txias txias, yog li cov hlau alloy steel spikes (nrog rau qhov zoo qis- kub toughness) yog nyiam. Kev txhim kho yog ua tiav sai kom tsis txhob cuam tshuam ntev ntawm cov cuab yeej thiab cov khoom siv rau qhov txias, xyuas kom cov spikes raug kho kom raug.
