既有线更换提速道岔施工技术

Construction technology of changing the original rail track into speed-raising turnout

以京沪线黄河涯站、三唐站更换GLC(06)01型提速道岔为例,从前期道岔测量定位、道岔预铺、要点施工慢行前、慢行中、封锁后等施工工序,详细介绍了更换提速道岔的施工技术,为相关工程实践提供借鉴与帮助。

Taking the example of changing the original rail track of Huangheya stop and Santang stop of Beijing-Shanghai railway into GLC （06）01 speed-raising turnout, it elaborates the construction technology of speed-raising turnout replacing from the first-phase turnout surveying and positioning, turnout pre-paving, construction procedures of key construction before low-speed running, in low-speed running, and after sealing, and elaborates the construction technology of speed-raising turnout replacing, which provides a reference for relevant projects.
