Background technique
Since plate-type ballastless track has, speed of application is fast, appearance is neat and artistic, later period adjustment is convenient, maintenance work
Outstanding advantages of amount is few, in recent years more and more urban track traffics start using plate-type ballastless track.Currently, operational railway
Plate accurate adjustment hole is all made of and flushes design with edges of boards, and existing major defect is as follows：
Track plates are the long prefabricated reinforced concrete structure of scale, and length is usually 3.5~6m, in 3 in Curve Segment, is
Track centerline is consistent with central lines of track after being laid with prefabricated board, needs certain offset is arranged at track plate end,
Then by fastener be finely adjusted in the way of handle.For the tunnel of shield section, profile be it is arc-shaped, plate end offset can lead
Causing track plates, wherein distance of the side plate bottom away from tunnel wall is less than general straight line location, and sweep is smaller, plate end offset
Also bigger, distance of the track plate bottom away from tunnel wall is also just smaller.In small curve radius location, track plate end offset mistake
Greatly, it will lead to accurate adjustment to grab in tunnel wall arc-shaped sections, and it is planar structure that lower cushion block is grabbed in accurate adjustment, it is difficult to arc tunnel wall
Matching, and distance of the board bottom away from tunnel wall is too small, accurate adjustment often occurs and grab not placing, being difficult to carry out showing for track slab precision adjustment operation
As.
