Exploration and Development of Small Cleaning Machine Turnout Cleaning and Screening Construction Organization

道岔一直是线路的薄弱环节，国铁集团对道岔清筛的施工组织一直处于探索阶段。本文以京沪线集中修小型清筛机对15组道岔的清筛施工为例，介绍了小型清筛机道岔清筛的工程概况、机械参数、施工组织、作业流程、效率分析及对未来的展望，分析了本次施工组织的收获与不足，为我国的小型养路机械机械化清筛施工项目的深入开展提供技术指导及工程建议。Turnouts have always been a weak link in railway lines, and China State Railway Group Co., Ltd. has been in an exploratory phase regarding the construction organization of turnout ballast cleaning. This paper takes the ballast cleaning operation of 15 sets of turnouts using small-scale screening machines during the centralized maintenance of the Beijing-Shanghai Railway Line as a case study. It introduces the project overview, mechanical parameters, construction organization, workflow, efficiency analysis, and future prospects of small-scale turnout screening operations. The paper also analyzes the achievements and shortcomings of this construction organization, aiming to provide technical guidance and engineering recommendations for further development of mechanized ballast cleaning projects using small-scale maintenance machinery in China.
