Abstract

The invention relates to a method for producing load transferring regions in a ballast body of a track superstructure by introducing curable liquid plastics or reactive plastic mixtures from a mixing unit by means of at least two distributor pipes with outlets into the load transferring regions and allowing the plastic or the reactive plastic mixture to cure in said load transferring regions. The two distributor pipes with outlets are positioned on the left or on the right from the outside of the rails into the region between the two rails such that the outlets are located adjacent to each other and are laterally spaced from the front face ( 3 ) of the tie ( 2 ) that has the load transferring region to be reinforced. The two outlets are opened in order to allow the plastic or the reactive plastic mixture to exit at a controlled rate. Each distributor pipe outlet is guided to the respective end face ( 4, 4 ′) of the tie ( 2 ) from the inside to the outside in a lateral manner with respect to the front face ( 3 ) of the tie ( 2 ) and around the respective end face ( 4, 4 ′) of the tie ( 2 ) to the rear face ( 5 ) of the tie ( 2 ). The distributor pipe outlets are guided in a lateral manner along the rear face ( 5 ) of the tie ( 2 ) into the region between the two rails ( 9, 9 ′) such that the outlets are located adjacent to each other and are laterally spaced from the rear face ( 5 ) of the tie ( 2 ).

First claim

The invention claimed is:

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.
