1. Process for the production of load transfer regions strengthened with plastic in a ballast, containing ballast stones and, in parts, plastic, of a superstructure which consists of at least ballast, sleepers and rails, by introducing liquid, curable plastics or plastic reactive mixtures into the load transfer regions from a mixer unit by means of at least two distributing pipes with outlets, and leaving the plastic or plastic reactive mixture to cure in these load transfer regions, characterized in that, to introduce the plastic or plastic reactive mixture,
1) the two distributing pipes with outlets are positioned on the left or right from outside the rails (1,1′), preferably underneath the rails, until they reach the region between the two rails (6,6′), so that the outlets are next to one another and laterally at a distance from the front (3) of the sleeper (2) whose load transfer region is to be strengthened, 2) the two outlets are opened to allow plastic or plastic reactive mixture to flow out in a regulated amount, 3) the outlets of the distributing pipes, each at the side of the front (3) of the sleeper (2), are guided from the inside to the outside up to the respective end (4,4′) of the sleeper (2) and around the respective end (4,4′) of the sleeper (2) up to the back (5) of the sleeper (2), 4) the outlets of the distributing pipes are guided, preferably underneath the rails, laterally along the back (5) of the sleeper (2) until they reach the region between the two rails (9,9′), so that the outlets are next to one another and laterally at a distance from the back (5) of the sleeper (2) whose load transfer region is to be strengthened, 5) the outlets are optionally closed and 6) the outlets of the distributing pipes are guided to another sleeper and the process (steps 2) to 6)) is repeated at this sleeper |
