Ankre teknoloji ak amelyorasyon rezistans nan Spikes tren
- Ki diferans ki genyen ant souf ak résine ancrage nan dormeur konkrè?
Ajan ancrage souf (souf: siman: sab=1: 0 . 3: 1) koute ¥ 5/moso, ofri pi gran pase oswa egal a 60kn rale - soti fòs, pou ray konvansyonèl; résine anchor (e . g ., epoksidik) gen pi gran pase oswa egal a 80kn fòs, vit geri (5min), pi bon rezistans move tan, pou HSR . sou ou te gen sulfur, résine a te gen pou yo te gen 3 an. ak résine.
- Ki sa ki avantaj ki genyen nan "konsepsyon Threaded" pou Spikes an bwa Travelers?
Spikes Threaded (ton 3mm, wotè 1 . 5mm) Ogmante rale - soti fòs pa 50% via fib anklanchman . kontwòl fil pwofondè (70% nan longè spike) pou fè pou evite divize dormeur . yon tren forè redwi spike rale - soti nan 15% a 5% ak Threak,,,, ak soti nan 15% ak wezin.
- Ki jan yo fè "rale - soti fòs tès" apre Spike mare?
Sèvi ak idwolik Pullers (100kn ranje), chaj nan 5kn/min, dosye maksimòm fòs . echwe si rale - soti<60kN (concrete) or <40kN (wood). Sample 3/1000 spikes; double sampling if 1 fails. A construction site's 50kN pull - out force was due to wrong sulfur mix, corrected by re - anchoring.
- Ki sa ki anti -mezi korozyon yo te itilize pou Spikes nan "saline - zòn alkali"?
Sèvi ak Zn - Alloy Alloy Spikes (10-15% al), pase 2, 000 - èdtan tès espre sèl, 3x validite nan Spikes galvanised . Passivate sifas ki gen 5% kwomat pou 10min anvan ancrage {{{ pou 5 ane ak Zn - Al Alloy .
- Ki sa ki danje yo nan "ensifizan Spike ancrage pwofondè" nan tras la?
<160mm depth in concrete sleepers reduces pull - out by 40%, causing "spike floating" and gauge changes. A line with 140mm depth had 3 derailments in six months; re - anchoring to standard restored stability. Use positioning jigs for consistent depth.
