DeDtvi -2 järnvägsfästningssystemär en elastisk separerad fästlösning som är allmänt använt i tunnelbaneteknik, speciellt utformad för att uppfylla metrolinjekrav för vibrationsminskning, justerbarhet och stabilitet i applikationer i urbana järnvägstransit .
Structurally, the system consists of spring clips, insulated gauge blocks, baseplates, rail pads, plate pads, T-bolts, nuts and flat washers. It employs Type I spring clips providing reliable clamping force to securely fasten rails. The insulated gauge blocks, made of high-strength engineering plastics, serve dual functions of electrical insulation and gauge adjustment through utbytbara block med olika specifikationer . De duktila järnbasplattorna erbjuder stabilt stöd, arbetar med elastiska dynor med dubbla skikt (järnvägsplatta + platta pad) för att bilda den tvåstegs elastiska strukturen som säkerställer överlägsen vibrationsdämpningsprestanda .}
Performance-wise, the DTVI-2 system demonstrates multiple advantages. Its outstanding vibration reduction comes from the two-stage elastic design with relatively low vertical static stiffness, effectively absorbing train-induced vibrations and minimizing environmental impacts. The system provides ±10mm gauge adjustment through different thickness gauge blocks and approximately 15mm vertical Justering via variabel järnvägstjocklek, tillmötesgående spårparametermodifieringar under både konstruktion och drift . Utmärkt isoleringsprestanda garanteras med isoleringsmotstånd som överstiger 10⁸Ω för både mätblock och elastiska dynor, vilket säkerställer korrekt spårkretsfunktion .
In application, the DTVI-2 fasteners are primarily used in general vibration reduction sections of metro main lines and branches, having been adopted in multiple metro lines in cities like Guangzhou and Shenzhen. The design thoroughly considers metro operational characteristics including high train frequency and significant vibration loads, enabling long-term performance under repeated impacts while maintaining stable rail Positionering - Tillhandahålla en solid spårfundament för säkra och effektiva metrooperationer .
