Urban Subway Construction New Supporting Technology And Equipment Research And Development

This article is a short sleepers in traditional and innovative cons-truction methods, steel spring floating slab track bed "steel cage assembly integration" construction equipment and industrial machinery design and renovation, feed opening tilt Metro narrow row hanging rail construction under way the new rail row lifting device, laying new variable cross hanging door method development and further broaden the base of short sleepers track bed rail cant overall quality control of the subway tunnels, deepen research and summarize research in practice through the construction, testing, for several construction equipment for innovative design and improved construction eq-uipment deficiencies exist, to design a new improved chassis rigidity pouring sleeve construction technology, the new "integrated" gutter casting mold construction program and to achieve the overall steel spring floating slab mechanized construction steel cage to solve the problem of the construction of urban rail under the spout of the standard gauge narrow row overall tilt lifting and optimized disassembly process on track in the tunnel construction lifting equipment, whi le optimizing the use of the rail support bracket design, improve the quality of rail cant control.Comprehensive discussion the depth and breadth of these types of inn-ovative applications, to ensure construction quality and safety compared to the situation, can greatly improve the construction schedule, effectivel reducing the labor intensity of workers, project cost savings, has in the industry broader applicability, research topics can be widely applied in construction of all new subway track structure.
