客运专线铁路预埋套管式高速道岔板预制工艺特殊技术研究

Special Technology Research on Prefabrication Process of High-Speed Turnout Slab with Embedded Pipe Sleeves on Passenger-dedicated Line

结合预埋套管式高速道岔板的预制工艺研究,总结出包括预埋套管式高速道岔板的模具安装、钢筋骨架加工、预埋套管安装、道岔板脱模、翻面、运输及存放等方面的预制工艺特殊技术。这些研究成果的成功运用确保了预埋套管式高速道岔板预制件的质量指标满足客运专线铁路预埋套管式混凝土道岔板制造及验收技术条件(试行)规定,可供类似工程借鉴。

This paper,in combination with the research on the prefabrication process of the high speed turnout slab with embedded pipe sleeves,sums up its special technology of prefabrication process,including the mould installation,steel skeleton processing,pipe sleeve embedding and the turnout slab demoulding,turn-over,transferring,storage,etc.Based on the successful application of these research results,this paper concludes that the prefabrication quality indicators of the high speed turnout slab with embedded pipe sleeves can meet the requirements specified in relevant manufacture and acceptance conditions(trial implementation) of passenger-dedicated line and can be used as reference for similar project.
