Fremgangsmåde og indretning til opbygning af en fast jernbane

The construction method uses concrete block (16) and steel (18) sleepers, with two reinforced individual blocks. The reinforcements extend mainly parallel to the sleeper axis. They consist of structural steel bars, connected by clips to form a reinforcing cage. The bars act as connection bars and extend through both blocks, with at least some projecting over the outer block ends. The longitudinal reinforcements, which had previously been placed loosely in the concrete pan, are lifted, and connected to the connection bars and the projecting bar ends. The preassembled tracks modules are adjusted using a number of regulating gantries, located on the concrete pans.
