Abstract
The invention discloses an integral ballastless track, aiming to prolong the service life of a track structure and meet the requirement of the ballastless track on stability and comfort. The track comprises a track slab (10), an adjusting layer (20) and a supporting layer (30), wherein the track slab (10) is paved on the adjusting layer (20) along the line extending direction; multigroup pre-stressed steel bars (11) are distributed transversely in the body of each track slab (10) at intervals; a filling layer (13) is arranged in a seam between two adjacent track slabs (10); the pre-stressed steel bars (11) corresponding to the track slabs (10) are vertically connected and apply pre-stress in segment to form the integral track slab. The integral ballastless track has the advantages of track integration improvement, even track rigidness, fulfillment of requirements of the ballastless track on the stability and comfort. The ballastless track effectively solves the problems that the filling layer between track slabs is easily cracked, and vertical ends of the track slabs are easily warped, can reduce the workload for maintaining and repairing the track structure, and improve the service life of the track structure.
Description
Technical field
The present invention relates to railway ballastless track, particularly the structure of non-fragment orbit.
Background technology
China recent years is built high-speed railway and Line for Passenger Transportation just energetically, will lay non-fragment orbit more and more.Ballastless track structure relates generally to the track plate, adjusts decks such as layer and supporting bed.Supporting bed adopts concrete structure, and the adjustment layer that is layed on the supporting bed end face is the deck that non-fragment orbit structural adjustment and power transmission are supported.The track plate adopts prestressed reinforced concrete structure, for avoiding the plate body cracking, laterally is laid with many group prestressed steel bars in the plate body.Track plate road along the line bearing of trend is laid on to be adjusted on the floor, leaves the gap between the longitudinal terminal surface of adjacent two blocks of track plates during laying, and after the adjustment of track plate was in place, the potting resin mortar formed packed layer in this gap.In existing ballastless track structure, the track plate has just applied prestressing force by its prestressed steel bar to plate body when plant produced, and laying between every block of track plate after installing is independently.Its weak point is, after circuit moves a period of time, packed layer between the longitudinal terminal surface of adjacent two blocks of track plates can ftracture, and the longitudinal end of track plate easily produces warpage, and this causes adverse influence can for the life-span of stationarity, comfortableness and the track structure of train operation undoubtedly.
Summary of the invention
Technical problem to be solved by this invention provides a kind of integral ballastless track, can not only satisfy the requirement of non-fragment orbit to stationarity, comfortableness effectively, and can reduce the track structure maintenance, repair, increases the life-span of track structure.
The technical solution adopted for the present invention to solve the technical problems is: integral ballastless track of the present invention, comprise the track plate, adjust layer and supporting bed, track plate road along the line bearing of trend is laid on to be adjusted on the floor, the lateral separation is laid with many group prestressed steel bars in each track plate plate body, be provided with packed layer between the plate seam of adjacent two track plates, it is characterized in that: the prestressed steel bar of described track plate correspondence vertically links to each other and segmentation applies prestressing force formation integral rail plate.
The invention has the beneficial effects as follows, each track plate vertically links to each other and forms the integral rail plate, and this integral rail plate segmentation is applied prestressing force by the prestressed steel bar after connecting, improved the globality of track, orbit rigidity is even, can satisfy the requirement of non-fragment orbit to stationarity, comfortableness effectively; Solve the problem that packed layer is easy to crack between the track plate, track plate longitudinal end easily produces warpage effectively, can reduce track structure maintenance, repair workload, increased the life-span of track structure.

The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
With reference to Fig. 1, Fig. 2 and Fig. 3, integral ballastless track of the present invention comprises track plate 10, adjusts layer 20 and supporting bed 30, track plate 10 road along the line bearing of trends are laid on to be adjusted on the floor 20, the lateral separation is laid with many group prestressed steel bars 11 in each track plate 10 plate body, is provided with packed layer 13 between the plate seam of adjacent two track plates 10.Different with existing non-fragment orbit is that the prestressed steel bar 11 of described track plate 10 correspondences vertically links to each other and segmentation applies prestressing force formation integral rail plate.This integral rail plate has improved the globality of track, orbit rigidity is even, can satisfy the requirement of non-fragment orbit effectively to stationarity, comfortableness, solved simultaneously the problem that packed layer is easy to crack between the track plate, track plate longitudinal end easily produces warpage effectively, thereby reduce track structure maintenance, repair workload, increase the life-span of track structure.
In the track laying construction of reality, can adopt following job practices usually, lay several piece track plate 10 earlier, vertical connection back prestressed steel bar 11 is carried out stretch-draw apply prestressing force, form the track slab construction The initial segment.Lay several piece track plate 10 respectively in vertical both sides of The initial segment then, vertical connection back prestressed steel bar 11 is carried out stretch-draw apply prestressing force, form the track slab construction extension.
The connected mode of prestressed steel bar 11 can be fixedly connected or removably connect.Consider from laying and the adjustment aspect of being convenient to track plate 10, the preferred employing removably connects, with reference to Fig. 2 and Fig. 3, the relative prestressed steel bar 11 of described adjacent orbit plate 10 longitudinal terminal surfaces removably connects by connecting elements 40, and connecting elements 40 is positioned at the anchor recess 12 of adjacent orbit plate 10.
Fig. 4, Fig. 5, Fig. 6 and Fig. 7 show the concrete structure of three kinds of adoptable connecting elementss 40 respectively.With reference to Fig. 4, described connecting elements 40 is a sleeve, and this sleeve has the inner bolt hole that matches with prestressed steel bar 11 longitudinal end thread segments; With reference to Fig. 5, described connecting elements 40 is a sleeve, and this sleeve has the inner bolt hole that matches with prestressed steel bar 11 longitudinal end thread segments, and the inner bolt hole two ends are respectively left-handed thread section, right-handed thread section; With reference to Fig. 6 and Fig. 7, described connecting elements 40 is made of locking nut 44 and framework 41, and framework 41 has two vertical load end faces 42, vertically offers on the load end face 42 for prestressed steel bar 11 longitudinal end thread segments and penetrates through hole 43 in the framework 41.
For further strengthening the globality of non-fragment orbit, with reference to Fig. 2 and Fig. 3, described packed layer 13 is the resin mortar layer, and the longitudinal terminal surface bonding of this resin mortar layer and track plate 10 forms monolithic construction.Described adjustment layer 20 can adopt the self-compacting concrete layer, and the door shaped steel muscle of this layer of concrete and track plate 10 bottom surfaces forms the composite board type track structure.
Some principles of the above integral ballastless track of the present invention that just explains through diagrams, be not be the present invention to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized, the claim that all belongs to the present invention and applied for.
