DeDT -järnvägsfästningssystem, som en mogen fästlösning för stads järnvägstransport, visar enastående prestationsfördelar inom vibrationsminskning, justerbarhet, miljöresistens och underhåll, och uppfyller perfekt driftskraven för tunnelbanor och lätta skenor .
Its most significant advantage lies in superior vibration damping. The two-stage elastic design combines rail pad and plate pad to achieve approximately 21kN/mm vertical static stiffness, reducing acceleration transfer function values by 5-10dB compared to conventional fasteners. This "dual damping" structure effectively absorbs vibration energy generated by train operation, minimizing Effekter på tunnelstrukturer och omgivande byggnader . Särskilt lämpliga för tunnelbanelinjer i stadscentra, det säkerställer både operationell jämnhet och miljövänlighet .
The system provides flexible and precise adjustment capabilities. Gauge adjustment is achieved through polygonal gauge blocks - quadrilateral blocks allow 6mm adjustment while hexagonal blocks reach 10mm, meeting lateral precision requirements. Vertical adjustment up to 15mm is possible by stacking pads of different thicknesses, accommodating elevation changes caused by subgrade settlement or rail slitage . Denna modulära justering kräver inga komplexa verktyg, vilket säkerställer hög konstruktionseffektivitet och anpassningsförmåga till långsiktiga spårgeometriförändringar .
Utmärkt miljöbeständighet är en annan nyckelfunktion . Metallkomponenter som T-bultar och basplattor har antikorrosionsbehandlingar (E . G . Zinc Plating), Demonstration Outstanding Performance in Metro's fuktiga och dammiga miljöer-Passing 480-} Hour Salt SprayTs utan röda röda Red Red-tester {{Insulation) high-strength nylon materials maintaining stable resistance above 10⁸Ω, preventing stray current interference with track circuits and ensuring reliable signaling system operation. Rubber pads employ anti-aging formulations with less than 20% elasticity degradation between -40℃to 60℃, suitable for various climate zones.
The system offers controllable maintenance costs. Standardized design of wear-prone components like spring clips and gauge blocks enables replacement without disassembling the entire structure - single component replacement takes only 10-15 minutes. With simplified connections and fewer failure points, the system requires 30% less maintenance frequency throughout its lifecycle compared to conventional fasteners, significantly reducing service interruptions -Idealisk för högpassagerare-volym stadslinjer .
