Abstract:Research purposes: As the track standard of high - speed railway is high,sometimes the switch has to be installed on frame type bridge due to the limitation of the landscape. So it is necessary to research and summarize the construction technology for laying slab ballastless slab track in switch area on frame type bridge.
Research conclusions: The construction technology for laying slab ballastless slab track in switch area on frame type bridge includes technologies of laying the extruded board and sliding layer with high stremgth,pouring the concrete of base layer,laying the switch slab,pouring the emulsified asphalt slurry,nailing the switch slab and producing lateral chock block. The construction technology for laying ballastless slab track in switch area on frame type bridge is very complex with many work procedures. It must ensure and strictly control the construction quality and precision in order to meet the requests of less maintenance and high regurality of slab ballastless track in switch area on frame type bridge.
