At present, the operational life of high-speed railways in China have been gradually reaching to the major overhaul period of 10-12 years. In order to study how accomplish efficiently the replacement of integral droppers in batches, combined with the practice of construction project for replacement of integral droppers in batches in Chongqing-Wanzhou section of Zhengzhou-Chongqing high-speed railway, the WBS work structure decomposition method is applied to dissect the construction workflow, analyze the construction organization process, key points of risks restricting the construction organization efficiency by application of JJC type maintenance train, and put forward the high efficient construction methods, providing reference for execution of replacement of equipment and major overhaul by application of JJC type maintenance train in the future.
