Abstract
A method for installing a permanent railroad track, for which the concrete railroad ties, carrying the tracks, are lined up positionally in a concrete trough and embedded in a casting compound with embedment in longitudinal reinforcements, in that, to begin with, the tracks with the railroad ties are pre-assembled into a track lattice, which is lined up with the upper edge of the rails and subsequently cast, 2-block concrete railroad ties with two reinforced individual blocks being used, the reinforcement comprising essentially structural steel rods, which run essentially parallel to the axis of the railroad ties, are connected by axially spaced-apart shackles into a reinforcing cage and extend continuously as connecting rods through both individual blocks, at least some protruding beyond the outer end surfaces of the individual blocks and the longitudinal reinforcements, which were previously placed loosely in the concrete trough, being raised and connected with the connecting rods and with the ends of the structural steel rods protruding on the outside, as well as a track-regulating gantry for implementing the installation method.
