Description
Technical field
The present invention relates to the railway technology field, specifically, relate to a kind ofly can adapt to city and inter-city rail transit, be widely used in high-speed railway (comprising Line for Passenger Transportation, passenger-cargo mixed transport line road, railway line for freight traffic) again, even can satisfy the plate-type slag-free orbit that speed per hour is the even running of 350km/h bullet train.
Background technology
At present, China railways generally adopts ballasted track.Ballasted track has reached the limit of supporting capacity under long-term high speed, heavy haul train load act on repeatedly, show ballast bed destruction is constantly aggravated, the smooth-going degree variation of track, the maintenance activity amount strengthens, available maintenance time is fewer and feweri, and this has seriously hindered railway and has developed to the direction of high speed, heavy duty.
It is the plate-type slag-free orbit of target that Japan's iron railway begins one's study with few maintenance from nineteen sixty-five, through the examination shop, several places on the rapid transit railway of national the Shinkansen, 1970 in the adret the Shinkansen first a large amount of constructions achieve success.Under study for action as plate-type slag-free orbit key technology---shock-absorbing type and multiple type track plate, elastic adjusting layer material (CA mortar) are used widely.Through the experimental studies in more than 40 years and examination shop, Central Japan Railway has accumulated rich practice experience, in recent years again according to its different service condition, as: warm area, cold district, coastline, vibration damping section, field patch etc., develop various CA mortar prescription and packing material, and corresponding method for testing performance, construction technology etc. have been proposed, use in the all-round popularization of Japanese the Shinkansen for the slab track structure and laid solid technical foundation.So far Central Japan Railway has been laid plate-type slag-free orbit to reach 2500km many.
China also has examination to spread the track structure that is close to few maintenance line, but the operating expenses height, speed of application is slow, substructure distortion trimming in a single day difficulty, and only limit to some special locations.
