摘要
The superstructure has short longitudinal concrete beams (1) carrying the rail fitting into a series of similar short. U-shaped trough supports (2). The beams and supports are connected by anchor rods (3) and mortar to form a monolithic homogeneous unit. The. U-shaped lower part forms a permanent shutter to contain the mortar. The top of the lower part serves as a guide for correctly aligning the track.
