Technical requirements for laying turnout cement sleepers and cement sleeper track laying
Selection of rails/steel rails, track gauge is, rail laying length is. The sleepers are made of reinforced concrete sleepers, sleeper specifications are length, width and height, sleeper design spacing
Use long steel rails for the tracks. The track bed is laid with stones of diameter and thickness.
The design width of the pipe trench is ㎜, the track laying length on the pipe trench is ㎜, the mining I-beam + channel steel sleeper is used to bear the load, the length of the I-beam is ㎜, the spacing is ㎜, and I-beams are left on the track bed on both sides of the pipe trench. The length of the upper part of the steel channel is mm, the length of the lower part is mm, the width is mm, and the depth is mm
The channel steel sleepers are made of channel steel. The upper track of the pipe trench is equipped with tie rods, which are respectively arranged under the channel steel sleepers.
The pipe trench cover plate is made of ㎜ steel plate and welded with angle steel.
After the track bed is hardened, the hardness of ordinary concrete must be guaranteed, and the ingredients should be proportional to cement, sand, gravel, water
and quality standard requirements
The track adopts / high-quality steel rails, and the track fasteners are complete, strong and consistent with the rail type. The gap between the track joints shall not be larger than that, the height and left-right errors shall not be larger than that, and there shall be no hard bends.
Track spacing, straight section and widened curve section gauge deviation is +.
The height difference between the top surface of the straight rail section and the height deviation between the outer rail in the curved section and the top surface of the inner rail after the curve section is heightened according to the design must not be greater than the height difference.
Sleeper spacing, sleeper spacing deviation +, sleeper specifications, sleeper embedded depth in the track bed. The sleepers are paved with gravel for about 10 feet. Sleeper rails must be firmly fixed to the track and perpendicular to the track. The upper end of the sleeper must be flush.
The track bed must be leveled and compacted, and tracks with suspended sleepers are strictly prohibited.
The track is laid flat and firmly, and the ballast is firmly padded.
