Description

Technical Field

[0001] This invention relates to the field of railway engineering construction for new and expanded railway projects, and provides a modular maintenance platform for protecting and facilitating maintenance of trackside signaling equipment on all conventional railways after the renovation and upgrading of existing railways and major and medium-sized electrical maintenance projects. Background Technology

[0002] In the past, the height of trackside signaling equipment on conventional railways was affected by the varying elevations of the roadbed and ballast, coupled with rigid distance restrictions relative to the rails and sleepers. This resulted in exposed foundations and increased burial depth, exacerbating instability and fragility. It also increased the difficulty of maintenance and negatively impacted the aesthetics of the track environment. The traditional solution was to construct a hardened surface on-site using red bricks and cement mortar to prevent equipment displacement, facilitate maintenance, and improve stability, safety, and track environment. However, on-site construction inevitably required significant track maintenance windows, material delivery, and a large influx of labor, negatively impacting transportation operations. Furthermore, the hardened surface was susceptible to weathering and cracking due to time and climate, posing safety hazards to vehicles and equipment. It also hindered major track maintenance, track cleaning, sleeper replacement, major and minor electrical repairs, and cable replacement, necessitating demolition and reconstruction. This resulted in inefficiency, wasted funds, and environmental pollution from the demolition work. Summary of the Invention
