Current Status and Prospects of Sleeper Replacement Technology for Railway Operation Lines
With the improvement of railway transportation quality and efficiency in our country,higher requirements was put forward for the status and safe operation of the railway lines.Concrete sleepers are key components in railway track structures.Accurate and efficient replacement of damaged and failed sleepers is of great significance for maintaining a good quality level of railway lines.At present,there are three main methods for replacing rail sleepers in domestic railway operation lines,including manual sleeper replacement,medium-sized mechanical sleeper replacement,and overhaul train sleeper replacement.The manual replacement of sleepers has low efficiency,high labor intensity,and average construction quality,but it has flexibility when a small number of sleepers are replaced.Medium-sized mechanical sleeper replacement construction has high efficiency,good construction quality,and low cost,but it has shortcomings in unloading and collecting rail sleepers.The overhaul train sleeper replacement is an integrated operation of unloading,replacing,and collecting sleepers,which has a high degree of mechanization and achieves net material after work.However,continuous improvement is needed in construction efficiency,mechanization of individual processes,and improvement of technical and economic efficiency.This article analyzed and studied the current situation and main problems in the development of rail sleeper replacement technology for domestic railway operation lines and put forward thoughts and prospects for future technological development.
