Background

The sleeper has the functions of fixing the track gauge of the railway track, bearing the weight load of the steel rail and passing through vehicles, enabling the pressure load of the track to be uniformly dispersed and transmitted to the roadbed and keeping the stable and smooth circuit. In the operation process, local sleeper of railway sinks, need maintain, the sleeper sets up between the rail, mostly square column shape, not only require to support the position that the rail kept the rail, suitable deformation is with buffer pressure and reconversion as early as possible when the train passes through again, still need transmit the huge pressure that the rail transmitted to the railway roadbed, need possess certain pliability and elasticity, the effect is very important, and the sleeper is under long-time high load pressure, very easily warp and damage, individual sleeper damages and even breaks, consequently must regularly change. Because the construction safety risk of the railway business line is high, the construction mode of manually replacing the sleeper in the skylight is usually adopted, the manual replacement of the sleeper is realized by purely manually taking off the ballast, taking out the old sleeper and penetrating into a new sleeper, the operation intensity is high, the efficiency is low, the labor input is large, and the construction cost is high. And ballast digging, sleeper drawing and replacing and ballast filling are required in the whole sleeper replacing operation process.

Common sleepers include wooden sleepers and cement sleepers. The cement sleeper has smooth appearance, hard inside, even elasticity, good insulativity, high stability, no influence of external conditions such as weather temperature and the like, no decay and long service life, and contains a plurality of screw-thread steels. Due to the characteristics, the cement sleeper replaces a wood sleeper at present.

When the powder crushed by the ballast in the ballast bed and the cohesive soil mixed in the ballast during construction are carried into the ballast bed, or the soil is brought into the ballast bed by wind blowing and water flushing, and the coal ash and the like of a train are mixed with the ballast bed, the ballast bed is unclean, gaps of the ballast bed are filled, a watertight course is formed, the drainage is unsmooth, the phenomenon of slurry turning and mud pumping occurs, the ballast bed is hardened subsequently, the elasticity is reduced, the damping effect is poor, and the ballast bed is required to be cleaned.
