Prefabricated steel structure subway station

Introduction

The subway station made of steel structure has become the preferred solution for modern urban rail transit construction due to its modular design, high-strength and lightweight characteristics, and fast construction advantages. Using Q355GJC high-strength steel and box section columns to achieve large-span column free space, combined with orthotropic steel truss roof and profiled steel plate composite floor, while meeting 9-degree seismic fortification, it reduces weight by 40% and shortens construction period by 50% compared to traditional concrete structures. Through BIM digital prefabrication and robot welding, ensure efficient and accurate on-site bolt connections. The triple anti-corrosion system and thick fireproof coating ensure a hundred year service life, and integrate fiber optic sensors for real-time monitoring of structural health. Its environmental characteristics are particularly outstanding, with 100% recyclable materials, a 60% reduction in carbon emissions, and the ability to expand the photovoltaic roof power generation function. 

Typical cases such as the all steel structure of Beijing Metro Line 28 achieving a weight reduction of 60000 tons, and the Dubai Metro extension line adopting maintenance free weather resistant steel design, both of which have passed international certification, demonstrate the comprehensive value of steel structure subway stations in terms of safety, efficiency, and sustainability.

The subway station made of steel structure integrates multiple advantages of modern engineering technology, using high-strength steel and modular design to achieve large-span column free space and rapid construction, reducing weight by 40% and shortening construction period by 50% compared to traditional concrete structures. Its innovation is reflected in the combination of the triple anti-corrosion system and intelligent monitoring system, ensuring a hundred year service life while achieving millimeter level precision control through BIM digital prefabrication and robot welding. Integrated with green functions such as photovoltaic power generation, materials are 100% recyclable and carbon emissions are reduced by 60%.

In summary, subway stations made of steel structures, with their core advantages of high strength, lightweight, fast construction, super seismic resistance, intelligent monitoring, and green environmental protection, perfectly embody the innovative concept of modern rail transit construction. They not only greatly improve engineering efficiency and quality, but also set a new benchmark for urban infrastructure construction with a hundred year durability design life and sustainable environmental characteristics, demonstrating the enormous potential and application value of steel structures in future smart city construction.
