Description
Technical field
The present invention relates to a kind of sleeper material.
Background technology
Sleeper claims again sleeper, is also a kind of of railway casting.Material therefor is not only timber only now, is therefore sleeper science more.Although the apperance dullness of sleeper is standardized, unprepossessing in appearance, can its effect is not little.Sleeper should supporting rail, the position that keeps again rail, and the immense pressure that also rail transmission will be come pass to railway roadbed again.It must possess certain pliability and elasticity, hard not all right, soft also not all right.Train is through out-of-date, and it can suitably be out of shape with compensator or trimmer pressure, but train must restore to the original state later as far as possible.
Concrete sleeper is with its long service life, and stability is high, and maintenance work amount is little, and damage ratio and the scrappage advantage more much lower than sleeper favored by various countries.On gapless track, reinforced concrete sleeper on average carries 15～20% than the stability of sleeper, therefore, is particularly useful for High-Speed Passenger transport line.As Japanese the Shinkansen, Muscovite high-spe-ed trunk line are all laid it.
Yet reinforced concrete sleeper also has shortcoming, especially weight ratio sleeper is much bigger.Such as, every of the reinforced concrete sleeper of Britain weighs 285 kilograms, and the U.S. weighs 280 kilograms, and Germany more also has 230 kilograms.So, at unsteady roadbed and newly fill out roadbed etc. and locate to adopt; Because its concrete elastic is poor, there is in the winter time the location of frost heave, generally do not allow to adopt.
Occurred that at present a kind of wooden inner core adds the sleeper of glass fiber covering; but because the character of covering and inner core material has big difference; bonding is firm not therebetween; cause practical value little; and do not break away from the loss to timber yet; be unfavorable for the protection of environment, and the technique that preparation is got up is also very complicated, is not suitable for industrial production.
