Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway track reinforcement technology, and in particular to a reinforcement device for existing railway tracks. Background Technology
[0002] As the core artery of land transportation, railways encompass key units such as tracks, roadbeds, bridge and tunnel facilities, stations, and signal control systems. Tracks, as the direct carrier of train operation, are precisely assembled from components such as rails and sleepers, bearing the functions of load transfer and guidance. Roadbeds, as the supporting foundation of the tracks, must possess resistance to deformation and durability to cope with complex working conditions. Bridge and tunnel structures must consider geological conditions and mechanical properties to ensure the continuity and safety of the line. Modern railway systems, through the integration of automated signal dispatching, intelligent power supply networks, and information management platforms, have achieved synergistic optimization of efficient operation and safety assurance, and are accelerating their evolution towards intelligence with the help of digital technologies.
[0003] During long-term operation, railway structures are susceptible to problems such as track geometry misalignment, rail fatigue damage, and roadbed settlement due to multiple factors including train cyclic loads, environmental erosion, and geological changes. Bridge and tunnel structures may also experience durability degradation due to material aging or water seepage. To address these issues, engineering projects utilize techniques such as track replacement, roadbed reinforcement, and bridge and tunnel structural strengthening to restore track performance. Simultaneously, non-destructive testing and real-time monitoring systems enable early identification and precise intervention of these defects. With the rapid development of heavy-haul and high-speed railways, the long-term service capacity of railway infrastructure has become a technological focus, driving continuous upgrades in reinforcement technology towards the application of high-performance materials, intelligent construction processes, and full-cycle health management.
[0004] Patent document CN220643666U discloses a limiting device for railway track reinforcement, including sleepers, limiting pins, threaded blocks, abutment blocks, and bolts. Two sets of limiting pins are symmetrically fixedly connected to the sleepers, and threaded blocks are movably connected to the limiting pins. The limiting pins and abutment blocks are connected in a cooperative manner. This utility model's railway track reinforcement limiting device, by placing the track body between two adjacent limiting pins on the sleepers, inserts the abutment blocks into the limiting pins, and then the bolts, after being inserted into the abutment blocks, are threadedly connected to the threaded blocks. Tightening ensures that the abutment blocks firmly abut against the bottom of the track body. This design reduces the number of components in the reinforcement limiting device, improving reinforcement convenience. When a train passes over the track, the vertical vibrations generated are absorbed by M-shaped elastic strips, without affecting the tight connection between the bolts and threaded blocks, thus improving the limiting stability.
[0005] As in the prior art of the aforementioned patent, the device is an existing component added to the original railway structure. This approach changes the original railway structure and may have the opposite effect. Furthermore, the structure only increases the firmness between the sleepers and the rails, but does not strengthen the structural strength between the rails and the ground. Utility Model Content
[0006] The purpose of this utility model is to provide an existing railway track reinforcement device to address the aforementioned shortcomings in the prior art.

[0008] As a further description of the above technical solution: the fastening assembly includes a fixing block fixedly installed on both sides of the reinforcing block and two double-ended screws, the double-ended screws passing through the two fixing blocks, and nuts provided at both ends of the double-ended screws.
[0009] As a further description of the above technical solution: the plug-in assembly includes an installation groove formed on the reinforcing block, and a grouting pipe is provided inside the installation groove.
[0010] As a further description of the above technical solution: the side wall of the grouting pipe is provided with a threaded part, and a drill bit is fixedly installed at the bottom end of the grouting pipe.
