Application Status and Structural Optimization Measures of Intersecting Crossover Turnout
Taking into account multiple key parameters such as track gauge,track type,number,type,and line spacing of intersecting crossover turnouts,a detailed statistical analysis was conducted on the usage of domestic main intersecting crossover turnouts,and the recommended intersecting crossover turnout types in relevant foreign standards were introduced.Through on-site research,the main problems at the diamond shaped intersection were revealed,such as damage to the frog rail components,poor positioning accuracy of the turnout sleeper,and insufficient ability of the fastening system to maintain track gauge.In response to these issues,targeted structural optimization measures have been proposed from multiple aspects such as fastening systems,acute angle turnouts,obtuse angle turnouts,and turnout sleeper structures.Specific measures include designing and applying pre-embedded iron seat type fastening systems at diamond shaped intersections to enhance lateral stability,using alloy steel combined acute angle turnouts to reduce the degree of point rail wear,and improving the bearing capacity and stability of turnout sleepers by enhancing their cross-sectional dimensions and reinforcement.These measures have reduced the maintenance workload of turnouts,extended the service life of diamond crossover,and thus improved the overall performance of the railway system.
