摘　　要：介绍了浙赣铁路电气化提速改造工程中所应用的12#可动心轨式提速道岔的基本情况,探讨了时速200 km的12#可动心轨式提速道岔组装施工工艺,以及封锁时间内更换道岔施工工艺.12#可动心轨式提速道岔在浙赣铁路电气化提速改造工程得到成功应用,并取得了良好的效果.Firstly, this paper introduces the basic situation of No. 12 raising speed turnout with movable nose frog in the speed-raising project by electrification on Zhe-Gan railway,and then it discusses the assembly and construction technology of No. 12 raising speed turnout with movable nose frog for 200 km/h high-speed railways. And it also introduces the construction technology of the replacement of turnout in using construction blocking time. At the end this paper points out the No.12 raising speed turnouts with movable nose frog are successfully applied in the speed-raising project by electrification on Zhe-Gan railway and obtain good results.
