Description

Railway plate die

Technical field

The present invention relates to a kind of mould of making railway ballastless track track plate.

Background technology

Ballastless track is with replacement shot ballast aggregate railway roadbeds such as concrete or asphalts and the track structure pattern of forming.It has good track stability, ride comfort, durability; Its structure height is low, from heavy and light, can reduce bridge second phase dead load and reduce tunnel clearance; Railway roadbed is neat and artistic, and the ballast aggregate in the time of can eliminating train operation splashes and efflorescence; Track deformation is slow, not only can significantly reduce track maintenance workload, and what is more important can reduce the demand in construction " skylight ", the transportation after being open to traffic is organized very favourable.Based on this, ballastless track becomes the first-selection of countries in the world high speed railway track structure, and particularly Germany and Japan adopt ballastless track substantially at the high-speed railway of building in recent years.China is the principal mode track with the ballasted track still at present, the ballastless track technology studied, but because Chinese track circuit transmission standard, promptly the signal of telecommunication is by track transmission, and this track plate that just requires to be layed under the rail has the good insulation performance function.Certainly, ballastless track is very high for the performance requirement that is layed in the track plate under the rail.

Summary of the invention

Based on above-mentioned need of practice, the objective of the invention is to: a kind of mould that is used to make ballastless track track plate is provided.
