As essential railway fasteners, gauge tie rods are typically installed at weak track sections such as turnouts, faulty sleepers, and sharp curves, working in conjunction with elastic clips, track bolts, and anti-loosening nuts to enhance track stability. GNEE RAIL provides a full range of railway fastening systems, including railway clips, high-strength bolts and nuts, railway spikes, flat washers, insulated gauge rods, and ordinary gauge rods, all manufactured from high-corrosion-resistant materials to ensure long-term durability of railway fasteners.
Turnouts, known for their complex structure, short service life, and high maintenance demands, are among the three key weak links in track systems. Frequent maintenance disrupts the operation of heavy-haul railways, making reliable reinforcement crucial. GNEE RAIL offers gauge tie rods in various specifications to better reinforce railway tracks.
Key roles of gauge tie rods in railway weak sections:
(1) Installing 20 sets of gauge tie rods on side rails can reduce wheel-rail lateral force and longitudinal force by 43.0% and 5.1% respectively. As the number of tie rods increases, all indicators improve; it is recommended to install 10-14 sets on turnout side strands, used in conjunction with turnout-specific fasteners such as spiral spikes and rail.
(2) Adopting a 1:20 rail bottom slope in turnouts can significantly reduce wheel-rail forces (14.8% reduction in lateral force and 16.7% reduction in longitudinal force), thereby enhancing synergy with rubber pads and iron base plates.
(3) Increasing the section width by 2mm can increase wheel-rail force/contact stress by up to 8.3% but reduce dynamic bending stress by 18.8%, optimizing the performance of components such as insulated gauge blocks.
On small-radius curves, tracks are subjected to complex forces. To prevent rail displacement, tipping, or gauge expansion on sleepers, elastic supports are vital. These supports, used in combination with fish plates, sleeper bolts, and welded gauge rods, maintain stability and ensure safe operation even under strong dynamic loads.
GNEE RAIL provides various specifications and standards of railway gauge tie rods, insulated gauge rods, ordinary gauge rods, flat washers, spiral spikes, under-rail pads, rubber pads, turnout pads, and other railway fasteners.
