1. Do railway sleepers have to be equipped with shoulders?
do not have to be equipped with shoulders. Therefore, the answer to this question is not necessarily the same. If there is a shoulder in the train track sleeper, the shoulder can resist lateral displacement and maintain good track direction and gauge. However, there are also non-shoulder bolt sleepers, which use pre-embedded positioning device to achieve fixed.
2. What kinds of railway sleepers are available according to different standards? And, what are the non-shoulder bolt sleepers made of?
There are different kinds of train track sleepers according to different standards. For example, in terms of structure, there are short short railway sleepers
and long railway sleepers
, horizontal and vertical sleepers, and wide sleepers, while in terms of laying position, there are ordinary, bifurcated rails and bridge rails.
The sleepers without shoulders and bolts are mainly composed of threaded screw rods, nuts, pressing plates, taper shafts, positioning pins, wrenches and spectacles plates. Among them, nuts and pressing plates are divided left and right. Threaded screw rods are divided into upper and lower screw rods.
3. How to fix the ballast and sleeper?
The fixation between ballast and sleeper is determined by the specific types of ballast. If it is a concrete ballast, then it is fixed by bolts; if it is a gravel ballast, it is fixed by sleepers themselves. Therefore, it is necessary to deal with specific situations in order to have a good fixed effect.
