Steel Structure Railway Station Maintenance Depot

The steel structure railway station maintenance depot is a complex system that integrates architecture, structural mechanics, railway engineering and process design. In our manufacturing plants in China, we divide the entire building into different components to achieve the prefabrication and assembly construction mode.

Structural form

● Frame structure: Suitable for maintenance sheds of ordinary passenger trains with relatively small spans and light loads.

● Grid structure: This is the most commonly used form in the maintenance sheds for high-speed trains and bullet trains at present. It is composed of many rods connected through nodes, forming a huge three-dimensional grid. Its advantages are: high rigidity and good seismic resistance. It can evenly distribute the weight of the roof onto the surrounding columns, thus achieving a large-span without columns of over 60 meters, allowing trains to be freely dispatched within the shed.

● Long-span arch or tube truss: For special maintenance workshops that require the lifting of extremely large components, this type of structure may be used to achieve a larger internal clearance.

Product case

Shanghai Hongqiao EMU Maintenance Depot

The roof of the maintenance shed at Hongqiao EMU Maintenance Depot was one of the largest steel structure grid roofs in China at that time. It was composed of thousands of steel rods, and each rod had bolts at both ends that were screwed into a solid steel ball. The advantage of this connection method is high installation accuracy, fast construction speed, and controllable quality. It is a complex system that integrates disciplines such as civil engineering, mechanical engineering, electrical engineering, and information technology. Its large-span grid roof was specifically designed to meet its efficient, three-dimensional, and flexible maintenance process requirements, and it is a perfect example of the unity of form and function.

FAQ

1. What is the design service life of the steel structure railway station maintenance depot?

Design service life: Usually 50 years.

2. How do the important equipment in the maintenance warehouse coordinate with the steel structure building?

● Three-story operation platform: The steel structure platform is closely attached to the train, allowing workers to simultaneously inspect the underside, interior, and top of the train (including pantographs and air conditioners), enabling three-dimensional operations.

● Bridge crane (crane): Suspended beneath the roof steel beams, it lifts 5-20 ton steering frames, motors, and other large components. Special crane beams need to be specially designed to withstand cyclic loads.

3. Why does the roof of the maintenance depot look like a grid? What's the special feature?

It is a bolted spherical node grid structure, like a huge three-dimensional spider web, composed of thousands of steel pipes connected by bolts to solid steel balls. Its advantage is that the load is distributed to all the members and surrounding columns, achieving an ultra-large-span space without columns.
