Disease Analysis And Improvement Measures Of General Railway Turnouts

Objective:Through a comprehensive analysis and statistics on the diseases discovered in a certain range of roads in the past two years,investigate the types and distribution patterns of diseases,and select a more representative ballast to conduct on-the-spot investigation through comparison,focusing on the investigation of the roads in the station.Location,maintenance and repair,find out the cause of the formation of the disease,and develop a maintenance and repair program for the prevailing diseases.As well as the daily maintenance requirements and operating standards,to ensure that the serious diseases of the turnout can be completely rectified,so that the switch is always in a relatively stable and balanced state to extend the service life of the ballast.Through the research on the key technologies and applications of the new domestic turnouts,the feasibility analysis of the improved improvement of the new turnouts developed in recent years is proposed.It focuses on the analysis of the disease,damage cause and service life of the existing highway line.The technical countermeasures for the service life of the universal speed switch are proposed,such as cleaning the track bed to improve the flexibility of the track bed and water slick;improving the smoothness of the ballast joint by grinding,and maintaining the maintenance and maintenance of the fish scales caused by fatigue.In order to reduce the maintenance workload of the road maintenance.Improve the running stability and safety of trains when they pass through,and prolong the service life of ballast rails.Thereby improving the overall safety reserve of the switch and providing reference for the formulation of the maintenance and repair strategy for the work.For the typical diseases of the ballast,a specific maintenance and repair plan is proposed.The plan includes the foundation and structural reinforcement measures.
