摘要
以某市地铁1号线工程为例,介绍了地铁整体道床单开道岔"散铺法"的施工工艺,并从底板处理、基标测设、道岔精调等方面,阐述了施工中的注意事项,指出"散铺法"能在保证工程质量和精度的基础上节省工期,值得推广应用。
Taking a Metro Line 1 engineering as an example, this paper introduced the "spreading method" construction technology of metro overall ballast bed single turnout, from the bottom slabs treatment, benchmark measurement, turnout fine adjustment and other aspects, elaborated the matters needing attention in construction, pointed out that “ spreading method” could save the time in guaranteeing engineering quality and precision, worthy of popularization and application.
