Background technology
With the development of China Railway High-speed technology, the type fragment-free track slabs of CRTS III are domestic in I template, II template at present
New achievement in research on the basis of research and application is the domestic optimization to existing non-fragment orbit with it is integrated, completely abolish
The terminal spine limit method of the boss of I template, II template, it changes the limit method of slab track, extends packed layer under plate
Material, optimize the aspects such as track plates structure, the plate-type non-fragment orbits of CRTS III be by rail, elasticity regardless of open type fastener,
It is prefabricated with shoulder block track plates, the interior self-compacting concrete packed layer and the armored concrete with limited impression for setting reinforced mesh
The part such as base constitutes, and sees accompanying drawing 1.The plate-type non-fragment orbits of CRTS III are that the country applies relatively broad in inter-city passenger rail construction
Primary trace form.But, at present in country's high-speed railway and PDL Construction design and construction, it is small to there is sweep,
The characteristics of superelevation value is big, self-compacting concrete packed layer easily produced in filling process laitance froth bed, track plates float and
The defects such as lateral displacement, maintenance difficult.Simultaneously because constructing operation precision and track plates constructional appearance size itself and loading end
Influence, under the slab warping of railway operation middle orbit and plate packed layer cracking be current III template orbital fashion be badly in need of solving it is main
Problem.
The content of the invention
It is an object of the invention to provide a kind of quick spacing assembling track plates of pretensioning prestressed concrete, solve
The installation structure of track of the type fragment-free track slabs of CRTS III occur be displacement, maintenance difficult and the slab warping of railway operation middle orbit and
Packed layer problems of crack under plate.

The prominent substantive distinguishing features of the present invention and significant progress are：
1. quick spacing assembling track plates of pretensioning prestressed concrete of the present invention, the tensioned prestressing bar before casting concrete,
And by the presstressed reinforcing steel anchoring temporarily of tensioning on mould, then casting concrete, treats that concrete curing reaches and is not less than coagulation
The 80% of native design strength value, it is ensured that presstressed reinforcing steel has enough bondings with concrete, comparative analysis longitudinal direction is double-deck, horizontal individual layer
Bidirectional pre-tensioned prestressed structure design, by comparative studies such as structural-load-carrying capacity, workability, structure detailing requiments,
Reasonable Arrangement distributing bar cage, longitudinal prestressing reinforcing bar and transverse prestressed reinforcing steel bar, improve the ductility of track plates structure and whole
Body, effectively absorbs and dissipation vibrational energy.
2. the quick spacing assembling track plates of pretensioning prestressed concrete of the present invention, the built-in ground rebar of distributing bar cage
It is connected with two-terminal-grounding terminal, realizes track structure integrated ground, concrete has stronger insulating properties, this characteristic in itself
Reach insulating requirements.
3. quick spacing assembling track plates of pretensioning prestressed concrete of the present invention, easily ensured with quality, durability is high,
The advantages of crack resistance is good, speed of application is fast, track recoverability is preferable, the track installation with the type fragment-free track slabs of current CRTS III
It is self-compacting concrete layer under the plate for cancelling adjustment track plates elevation that structure is compared, and increased isolation bed course, is limited by track plates
The positioning in position hole, improves the stability of track.Due to cancelling the self-compacting concrete layer of adjustment track plates elevation, not only solve
Displacement, warpage issues that the installation structure of track of the type fragment-free track slabs of CRTS III occurs, and construction and maintenance are very convenient, significantly
Reduce the maintenance cost after laying cost and railway operation.
