How is the Railway Fastening installed

From a structural point of view, Railway Fastening is mainly composed of elastic strips, spiral spikes, gauge baffles, underrail gaskets, flat washers, and embedded bushings located in prestressed concrete with shoulder stoppers. In addition, in order to adjust the rail height position, it also includes the adjustment of the backing plate. So, what is the order in which Railway Fastening is installed? In order to answer your doubts, our company will give you a brief talk about how Railway Fastening is installed.

Lay the underrail plate, place the underrail plate in the middle position of the bearing rail surface, and the flange of the bearing plate should be locked. The rail is laid, and the rail is laid on the underside of the rail. Install the gauge baffles on the outer side of the rail and the inner side of the rail, and place the gauge baffles between the two ears of the underside of the rail, and do not press the underside of the rail. Check the direction of the gauge, and replace the gauge baffles if any discomfort occurs. Due to the manufacturing deviation of rail, tie and gauge baffle, if the gauge baffle of the specified number is installed, it cannot meet the gauge requirement or the gauge baffle cannot be installed in place, it can be replaced according to the actual situation. It is necessary to pay special attention to that the gauge baffle should not press the bottom plate of the rail; When installing the gauge baffle, do not hit the gauge baffle violently to make it in place. Install the spring bar, place the spring bar in place, cover the screw spike with a flat washer and apply railway grease to the thread, then screw in the casing and tighten the spring bar. The fastening of the elastic bar shall be subject to the contact between the lower jaw of the central front end of the elastic bar and the rail. The criterion to determine whether the spring bar is installed in place is that the jaw of the middle front end of the spring bar is in contact with the rail, and the gap is not greater than 0.5mm.
