1. Yuav ua li cas koj xam qhov yuav tsum tau spike kom muaj nuj nqis ib km?
Formula:
Spikes/km=(1000/Tie spacing) × Spikes per tie
Piv txwv:
600mm khi spacing × 4 spikes=6,666 spikes/km
Ntxiv 5% ntxiv rau cov nkhaus thiab cov pob qij txha.
2. Dab tsi yog qhov txawv ntawm aub spikes thiab ntsia hlau spikes?
| Feature | Dog Spike | Ntsia Hlau Spike |
|---|---|---|
| Kev teeb tsa | Rauj{0}}tsav | Torque wrench |
| tuav lub hwj chim | 3-5 kN | 8-12 kN |
| Kev ua neej nyob | 10-15 xyoo | 20-25 xyoo |
| Nqi | $0.50 / unit |
$1.20 / unit |
3. Yuav ua li cas cov spikes tiv thaiv nyob rau hauv electrified txoj kev?
Cov kev ntsuas tshwj xeeb suav nrog:
Fiberglass-cov nylon ntxhua khaub ncaws
Muab ob npaug rau- txheej epoxy txheej
Zinc{0}} aluminium alloy plating
Tiv thaiv tsis tau tam sim no corrosion uas tuaj yeem degrade spikes 3x sai dua.
4. Yuav ua li cas hloov cov spikes puas lawm?
Tshem tawm ballast ncig lub khi
Extract qub spike nrog ruber
Ntxuav / khib nyiab lub qhov
Ntxig tshiab spike ntawm lub kaum sab xis
Tsav mus rau qhov dej ntws
Recompact ballast

5. Qhov ntev ntawm qhov sib txawv ntawm cov khoom khi li cas?
Ntoo khi:130-150 hli
Concrete ties:100-120mm (luv luv vim qhov ceev dua)
Composite ties:110-130 hli
Ntev spikes yog siv nyob rau hauv softwood ties piv rau hardwood.
