Background
With the continuous development of railway construction in China, the ballastless track is widely applied to railway construction due to the advantages of strong integrity, good smoothness, high durability, small maintenance amount and the like. The service state of the existing ballastless track shows that the ballastless track in a severe mountain area, such as a roadbed, a tunnel, a bridge and other track lines, has a large risk of upwarp or sinking deformation, so that the track structure on the ballastless track can deform along with the track lines, the geometric form of the track structure changes, the smoothness of the track lines is poor, a train is forced to slow down to pass, and the running safety is endangered when the train is serious, and the potential safety hazard is large.
The steel rail supporting structure of the conventional ballastless track is mainly a rail bearing platform on the upper part of a sleeper buried in a cast-in-place track bed or an integral rail bearing platform of a prefabricated track board in a factory, the rail bearing platform and the track board or the track board cannot be disassembled, and no fast-assembled combined rail bearing platform is applied. The adjusting capability of the ballastless track is mainly realized through the fastener, but the adjusting capability of the fastener is limited. Once the foundation under the ballastless track line is greatly deformed, the structure of the track bearing platform cannot be adjusted, the adjusting capability of the fastener is not enough to adapt to the deformation amplitude of the foundation under the track line, and the mode of replacing a ballast bed or a track slab is generally adopted or the foundation structure under the line is directly replaced to cope with the large deformation of the foundation. However, the maintenance time is long, the normal operation of the line is affected, and the cost is high.

When the adjustment direction of the first anchoring hole 12 is arranged along the transverse direction of the rail, as shown in fig. 2, or along the length extension direction of the oblique boss 11, as shown in fig. 3, the transverse displacement adjustment can be also realized to adapt to the deformation of the foundation under the rail line. Each part of the rail bearing platform can be prefabricated in a factory and installed on site, the movable supporting block 1 with the inclined bosses with different heights can be prefabricated and embedded with the adjusting block 3 in the specially-made concrete foundation 4, and a reasonable filling structure can be arranged between the movable supporting block 1 and the concrete foundation 4 as required to adapt to the large deformation of the off-line foundation.
Example 5
In contrast to the above embodiment, the anchor 5 may also be an embedded part including the anchor bolt 51, the anchor nut, and the washer 52. The anchoring piece 5 can be embedded in the concrete foundation 4 for fixation, or can be movably connected with the concrete foundation 4 but is limited in the relation of the internal structure of the concrete foundation 4, and is sequentially anchored on the surface of the movable supporting block 1 by a washer 52 and an anchoring nut.
In the above embodiments, the movable support block 1, the adjusting block 3 and the backing plate 2 may be made of polymer material, fiber material, or solid or cavity structure made of steel or concrete. The backing plate 2 may have a single-layer structure or a multi-layer structure.
In addition, it should be noted that, the term "oblique boss" and "oblique groove" as used herein means that the length extending direction of the boss or the groove has a certain angle with the width direction, and does not mean that the side surface of the boss or the side surface of the groove is oblique.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
