Development of rapid construction methods for grade separations This paper introduces TQB Methods for rapidly constructing grade separations in an urban area, which will provide an effective measure in the urban redevelopment for the settlement of traffic congestion. The construction of a grade separation will complete with these methods in an extraordinary shorter period (8.5months by securing traffics and 1.5 months by blocking the roads) than with conventional construction methods, which have taken about three years. There are three types in TQB methods: Type R of steel frame structures, Type B of concrete block structures and Type K using temporary truss bridge.
