The utility model discloses beneficial effect: the rail adopts the whole embed formula, and out of use tradition fastener has reduced the whole height of track system, makes things convenient for fire control, rescue vehicle to get into.
Description
Technical field
The utility model relates to a kind of for the embedded tracks structure in tunnel, belongs to technical field of rail traffic.
Background technology
In traditional tunnel inner orbit system, no matter be Ballast track system or ballastless track system, rail is all higher than sleeper or the Prefabricated integral fragment-free track slab of bottom.The weak point of this structure is, wheeled vehicle travels very inconvenient in tunnel, when particularly having an accident in tunnel, common fire-fighting will be had a strong impact on, breakdown lorry enter in tunnel implement fire-fighting and rescue.
In the embedded tracks disclosed at present, the transverse direction adjustment of rail is by adjusting the relative sliding of wedge on retainer to promote retainer and rail transverse shifting.But vertical adjustment wedge may cause the movement of rail vertical position, has an impact to rail absolute altitude.Therefore, this embedded tracks is not easy to construction.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, provides a kind of for the embedded tracks structure in tunnel, with overcome current conventional rails structure exist surface be uneven thus affect fire-fighting, breakdown lorry pass through shortcoming.In addition, the utility model also by providing noise reduction block and laterally adjusting wedge, solves the problem that can affect rail absolute altitude when laterally adjustment wedge adjusts in current embedded tracks.
The technical solution adopted in the utility model is such:
A kind of for the embedded tracks structure in tunnel, comprise Prefabricated integral fragment-free track slab, rail support groove is longitudinally offered respectively in both sides, described Prefabricated integral fragment-free track slab top, all the other positions of upper surface are plane, resilient sleeper-bearing under rail is set in described rail support groove from bottom to top, height adjusting cushion plate under rail, rail, described rail both sides arrange some noise reduction block respectively, fit in one side of noise reduction block described in every block and steel rail web surface, arrange between another side and rail support groove sidewall and laterally adjust wedge, in rail support groove, its complementary space is filled with Macromolecular pouring material, bottom described Prefabricated integral fragment-free track slab, cavity is set and be arranged on convex basis top convex block on realize horizontal longitudinal spacing, the degree of depth of described cavity is less than the height of convex block, the length and width of cavity are greater than the length and width of convex block respectively, after the convex block embedding Prefabricated integral fragment-free track slab bottom cavity at top, convex basis, by self-compacting concrete from the injected hole injection gap therebetween Prefabricated integral fragment-free track slab.Convex basis and Prefabricated integral fragment-free track slab are connected in one by self-compacting concrete.
As preferably, described rail support groove cross section is U-shaped, and the bottom surface of rail support groove is downward-sloping towards the horizontal middle part of Prefabricated integral fragment-free track slab.Rail support groove bottom angled is equivalent to the effect of rail cant, has rail cant can improve the contact relation of rail and car wheel-set, reduces rail abnormal wear
As preferably, the up-small and down-big flowing facilitating self-compacting concrete of described injected hole.
As preferably, along rail, longitudinally some noise reduction block are set at equal intervals.Carry out further preferably, described noise reduction block is divided into the band noise reduction block on inclined-plane and the noise reduction block not with inclined-plane, noise reduction block not with inclined-plane and laterally to adjust the one side that wedge contacts be plane, noise reduction block with inclined-plane and laterally adjust the one side that wedge contacts and divide three sections, two end portions is the plane of band gradient, and mid portion is a perpendicular.Some noise reduction block not with inclined-plane are evenly arranged between the noise reduction block on two pieces of band inclined-planes.Prefabricated noise reduction block effectively can reduce the workload of cast-in-site Macromolecular pouring material, and can reach the object of adjustment rail lateral stiffness.The macromolecular material of cast-in-site and the modulus of elasticity of prefabricated noise reduction block different, one is softer, and one is harder.The object of adjustment rail system rigidity can be reached by collocation that is soft, hard material.Noise reduction block with inclined-plane is with laterally adjusting wedge coordinates the effect adjusting rail lateral attitude in addition.
As preferably, the Macromolecular pouring material in described rail support groove differs at rail both sides height, shorter inside rail, higher outside rail.The design that inside Macromolecular pouring material, low outside is high, can meet the normal pass of Railway wheelset wheel rim.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
By in rail embed wholly track plates, do not re-use traditional fastener, and effectively reduce rail system whole height;
Very be applicable to common fire-fighting, breakdown lorry travels and enters, overcome the shortcoming existing for track structure conventional at present.
Use and vertically move along track the noise reduction block adjusting rail lateral attitude, the impact on rail absolute altitude when overcoming current embedded tracks system call interception rail lateral attitude.
