Concrete Sleeper is divided into bolt platen and U ring by installation. Cement sleeper u-ring sleeper is easy to install, just put the rail between the two U-rings, cushion the rubber plate below, then use a sledgehammer down u-ring pressure rail. Cement sleeper bolt pressure plate is to use t-bolts from the pillow rail below the reserved hole through the above fixed pressure plate pressure rail, a sleeper needs 4 sets of bolts, 4 pressure plate, 4 rubber pad (there are two large, two small), this pillow rail maintenance is convenient, can be reused.
Concrete Sleeper is a kind of supporting track made of cement. It is generally laid as a railway track, which can effectively buffer the pressure. Here we will introduce the role of cement sleeper.
Concrete Sleeper is mainly used for laying rails and as a platform for some special devices. Has the characteristics of long service life, good stability, on the high-speed line and traffic line use, can effectively disperse stress, avoid rail line deformation caused by the sinking, prevent the problems such as train derailed or slide, can guarantee the safety of the train, compared with wooden sleeper, not timber consumption, longer service life, higher stability and maintenance easier, Lower damage and scrap ratio. On the seamless line, the stability of reinforced concrete sleeper is improved by 15~20% on average than that of wooden sleeper, which is especially suitable for high-speed passenger transport lines. In addition, it can also increase the smoothness of train movement and reduce the noise caused by train running.
Concrete Sleeper is cement, sand, stone, high-strength rebar composition, is not afraid of water, not afraid of sun, not afraid of corrosion and other characteristics, cement sleeper also has strong stability, strong service life, good insulation, low maintenance costs. Specific advantages are as follows:
1, Concrete Sleeper needs a steam demoulding molding, smooth appearance, hard inside, and contains a plurality of rebar.
2, Concrete Sleeper material source is wide, the same specification, uniform elasticity, good insulation, high stability, not affected by weather temperature and other external conditions, not rotting long service life.
3. In addition to saving a lot of steel, the prestressed concrete sleeper has the advantages of long service life, good track stability, and can meet the requirements of high speed and large volume of transport.
