Product Introduction
The railway fastener system is a track connection system composed of gusset fasteners, sleeper bolts, rubber pads, springs, etc. It can be divided into prefabricated and cast-in-place types according to different construction processes. The prefabricated fastener system is assembled in the factory and installed directly on site, which can improve construction efficiency and shorten construction period; the cast-in-place type casts the components and sleeper concrete into one at the construction site, which is suitable for high-speed railway ballastless tracks that require extremely high track accuracy, ensuring the high accuracy and stability of the track structure.
From the perspective of system composition and function realization, the Nabla railway fastener system demonstrates an excellent design concept. The core structure consisting of Nabla springs, insulators, and high-strength connection components each performs its own functions and works closely together.
The buckling function of Nabla springs, the insulation function of insulators, and the fastening function of high-strength components play a key role in both ballasted and ballastless tracks. On ballasted tracks, it works together with the ballast to disperse the train load and reduce track settlement; in ballastless tracks, it cooperates with the elastic cushion to reduce the impact of train operation on the foundation, effectively improving the bearing capacity and durability of the track structure.
