[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Generally, the components of the embodiments of the present utility model described and illustrated in the accompanying drawings herein can be arranged and designed in various different configurations.

[0024] Embodiment:

[0025] As Figures 1 - 3 shown, the present utility model provides a damaged repair structure for a roadbed 1, which includes a roadbed 1 body and a support member. The roadbed 1 body includes a roadbed 1 and sleepers 2. The roadbed 1 is provided with a pull rod groove 3 for accommodating a link mechanism. The pull rod groove 3 is recessed into the interior of the roadbed 1. The link mechanism is used for lateral movement, and then drives the rail to move laterally, so that the moving rail is docked with different tracks, thereby realizing track switching. In order not to affect the normal operation of the rail, the link mechanism is arranged inside the recessed pull rod groove 3.

[0026] The roadbed 1 is also provided with a mounting groove 4 for mounting the sleepers 2. As Figure 1 shown, the mounting groove 4 is located on both sides of the pull rod groove 3 and the mounting groove 4 is higher than the pull rod groove 3. During the construction of the roadbed 1, the sleepers 2 are placed inside the mounting groove 4 and concrete is poured into the pull rod groove 3, so that the gap between the sleepers 2 and the roadbed 1 is filled with concrete, and finally the sleepers 2 and the pull rod groove 3 are firmly connected as a whole. A fastener 9 for connecting the track is provided at each end of the sleeper 2. The track can be connected to the sleeper 2 through the fastener 9. Since the side of the mounting groove 4 close to the pull rod groove 3 is thinner, the vibration of the sleeper 2 after long-term operation causes it to break and cannot well limit the sleeper 2.

[0027] The support member includes two side plates 5. The two side plates 5 are vertically fixed inside the pull rod groove 3 and are attached to the sleeper 2. Then, the sleeper 2 is tightened and positioned by the side plates 5.

[0028] The damaged repair structure of the roadbed 1 of the present utility model uses the side plates 5 to position the sleepers 2. The side plates 5 are fixedly connected to the inside of the pull rod groove 3, so that the side plates 5 can stably limit the sleepers 2 and prevent them from shaking. At the same time, the side plates 5 can be made of steel plates, which have good toughness and will not break easily due to the vibration of the sleepers 2. Ensure the durability of the roadbed 1 after repair.

[0029] In this embodiment, the support member further includes a bottom plate 6. Two side plates 5 are connected to opposite sides of the bottom plate 6, so that the entire support member is in a U-shaped groove. The two side plates 5 are spread out to both sides through the bottom plate 6. Thus, the vibrations of the two sleepers 2 can be transmitted to each other through the side plates 5 and the bottom plate 6, and then offset each other, thereby increasing the service life. This structure also allows the two sleepers 2 to press and restrict each other through the support member.

[0030] In this embodiment, the bottom plate 6 is fixed to the bottom of the tie rod groove 3 by bolts 7, so that the fixing of the support member and the track bed 1 is more stable and reliable.

[0031] In this embodiment, a filling layer 8 is provided between the side plate 5 and the sleeper 2, so that the side plate 5 abuts against the sleeper 2 through the filling layer 8. The filling layer 8 is actually a concrete layer. After the U-shaped support member is placed in the tie rod groove 3, there is still a gap between the side plate 5 and the sleeper 2. The two can be tightly connected by pouring concrete. In practice, a special repair mortar can be used here instead of conventional concrete.

[0032] In this embodiment, the filling layer 8 is a repair mortar. Steel bars are also provided inside the filling layer 8. Specifically, after the support is installed, a gap is reserved between the side plate 5 and the sleeper 2. Steel bars are implanted into the gap, or the steel bars can be made into a steel mesh and placed in. Finally, the repair mortar is injected into the reserved gap. After the repair mortar hardens, the sleeper 2 can be restrained. The provided steel bars also make the filling layer 8 stronger.

[0033] In this embodiment, the sleeper 2 is fixed to the ballast bed 1 by a plurality of bolts 7. The sleeper 2 is not only fixed by the repair mortar, but also fixed to the ballast bed 1 by the bolts 7, thereby making the connection stability of the sleeper 2 better. The bolts 7 of the sleeper 2 and the bolts 7 of the base plate 6 are both expansion bolts 7.

[0034] In this embodiment, a waterproof layer is also included. The waterproof layer is a waterproof material applied to the gaps between the ballast 1, the sleepers 2, the support members and the filling layer 8 and the cracks in the ballast, so as to prevent water vapor from entering the ballast 1 and reducing the durability of the track structure.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
