Development and Innovation of Construction Equipment for Railway Tunnel Lining in Operation
With the rapid development of railway construction in China,more and more railway tunnels have been built and put into operation.Some operating railway tunnels have suffered various diseases such as lining cracks,corrosion and water leakage.Due to the short time of the skylight point and the complex overhead contact network at the top of the tunnel,the commonly used operation method is to use scaffolding to set up a construction platform and carry out construction with simple tools,which has high labor intensity and safety risks.In the article,the system composition,technical parameters,and innovation points of three sets of operational railway tunnel lining construction complete equipment developed in parallel by China Railway Fifth Design Institute,China Railway Construction Heavy Industry Corporation,and China Railway Equipment are introduced in detail,and the use functions of the construction complete equipment are further studied.The possibility of developing it into a comprehensive maintenance equipment for railway infrastructure is studied.
