浅析城轨交通道岔整体道床施工

研究目的:道岔是城市轨道交通必不可少的轨道设备,道岔的施工质量对城市轨道交通安全运营、减少维修工作量、延长大中修周期起着重要作用,因此,本文就城市轨道交通中地下线路及高架线路道岔整体道床施工,进行粗浅分析研究。研究方法:搜集已建成的城市轨道交通工程道岔整体道床施工的资料,调查维修养护情况,总结了一套道岔整体道床施工方法和施工质量控制措施。研究结果:着重对城市轨道交通铺设较多的单开道岔、单渡线以及交叉渡线等整体道床施工的有关问题,如基标测设、施工难点、施工程序、施工方案、施工质量控制、施工机具等,提出见解。研究结论:城市轨道交通工程是一项系统工程,“轨通”是城市轨道交通工程完工的重要标志之一,道岔整体道床工程又是轨道工程的关键。为此,轨道施工人员应抓住施工难点,采用合理的施工方案,使用先进的施工机具,严格执行各环节质量控制程序,确保施工质量与进度。并应统筹策划,做好前期准备、后期协调及各系统施工接口工作。

Analysis of Turnout Monolithic Track Bed Construction in Urban Rail Transit

Research purposes: Turnout is absolutely necessary for urban rail transit,so the high construction quality can guarantee steady system operation and reduce maintain workload and prolong repair cycle.The article describes turnout monolithic track bed construction in underground and elevated track,and then does some study toward this.Research methods: First,the author collects relevant materials, and then investigates circumstance.In the end,the author sums up a suit of construction methods and quality master measures.Research results:The article describes construction of single turnout,crossover,scissors crossing,such as,survey of basic sign,construction difficulty,construction process,construction scheme,construction quality master and construction equipment(including mini-jack).Then the author brings out the problems and relevant analysis.Research conclusions: Urban track transit is a suit of systems engineering.Track transfixion is one great mark of urban track transit engineering completion.Turnout monolithic track bed is key to track engineering,so track builder should seize construction difficulty,adopt logical construction scheme,use advanced equipment,carry out staggered quality master program strictly and insure construction quality.And also,the people should plan as a whole,do former preparation and later cooperation well to insure construction quality.
