Abstract:
A simple movable formwork trolley is designed for the casting of the inverts of tunnels on passengerdedicated railways, on basis of summarizing the conventional invert construction technologies, so as to speed up the construction and reduce the construction cost, with the construction of the invert of the entrance section of Dazhai tunnel on GuiyangGuangzhou Railway as an example. The construction of the tunnels on the highstandard passengerdedicated railways can be effectively improved due to the application of the simple movable formwork trolleys. The practice shows that the simple movable invert formwork trolleys are superior to the conventional formwork trolleys and have resulted in rapid construction and good economic benefits.
Key words: passengerdedicated railway, tunnel, invert, movable formwork trolley, concrete compacting, deformation prevention technology
