Construction Method of Long Sleeper Buried Type Ballastless, Bed for Urban Rail Transit

Long sleeper buried type ballastless bed is a new track structure. The article based on the constructions of domestic similar kinds integrate ballastless bed constructions, according to the practical construction of Shanghai rail transit line 9 held by China Railway First Group Co., Ltd, completely and systematically expounded the construction technique flow of urban rail transit long sleeper buried integrate ballastless bed. Besides, the article also detailedly introduced key technology, construction working procedure and research and application of machine tools in construction. At present,; the construction, of China rail transit is in developing rapidly. This construction method is significant and valuable in the construction of urban rail transit long sleeper buried type ballastless bed and similar kinds railway structure constructions.
