Passenger dedicated track has ballasted sleepers, which is a type specifically used on passenger dedicated lines. Regarding its appearance, the image above has already showcased it, allowing you to understand its look. However, some fundamental aspects still require introduction and explanation, as well as related to the sleeper itself. So, let's delve into the specific content below.
Junction sleepers, which are typically used on railway switch tracks, differ in structure from standard sleepers. Currently, in China, wooden junction sleepers are predominant, but concrete and steel junction sleepers have also been developed.
Wooden switch sleepers: Their cross-section is similar to that of ordinary wooden sleepers, and their length is12 levels, ranging from 2.6 to 4.8 meters, with a 0.2-meter difference between each level. The connection with the bedding plate is via threaded dowels.
Concrete crossties: ItThe maximum length is 4.9 meters, with increments of 0.1 meters each. However, it features a shoulderless design. The top surface of the concrete crossover ties is flat, and it also includes components such as plastic sleeves.
Steel turnout sleepers: Developed primarily to meet the installation requirements for electrical conversion equipment, their outer width must be well-controlled to ensure sufficient tamping space between adjacent sleepers.
The spacing of the sleepers is also a crucial aspect; it must be well-controlled to ensure the uniform rigidity of the substructure beneath the tracks. Additionally, the track gaps should be centered in the spacing.
NewPhotos of Type II sleepers have been shown to us. From the pictures, they look similar to regular sleepers, with improved performance, but some knowledge remains the same. Therefore, the following introduction will be accompanied by its pictures to introduce some key points, so that everyone can get to know the new Type II sleepers.
The loading and unloading, as well as handling, of rail sleepers are:
(1) If transporting sleepers by road, the vehicle must have a mounting bracket that matches the sleeper size. After loading, secure the sleepers firmly to prevent shifting during transit.
(2) Between each pile of sleepers, insert a triangular wedge wood; two on each side are sufficient to prevent damage during transportation.
(3) When transporting sleepers, they should be carried smoothly. When placing them down, first set one end on the ground, then lower the other end. Do not throw them to prevent damage.
(4) When unloading rail sleepers, they must be gently placed, not dropped or struck. The same applies to fasteners; they must not be thrown to avoid injury.
