Abrégé

An apparatus for applying a single-component or multi-component adhesive to a ballast bed of a stretch of rails in a rail path, includes a container for the adhesive and elements for conveying the adhesive for application are mounted on a supply vehicle which can be driven on, or adjacent to, the rail path. The adhesive is guided from the supply vehicle with a hose having a one nozzle. The apparatus further includes a trolley that can be temporarily coupled and secured to a rail, and can be moved in a rail-bound manner at a desired and uniform speed independently of the supply vehicle. The trolley supports a boom on which the nozzle is mounted, so that a defined depth of penetration of the adhesive can be maintained by the apparatus at a uniform running speed of the trolley and defined flow rates of the adhesive depending upon the characteristics of the ballast bed and spray pattern.

The invention relates to a method for producing a permanent water tightness of a protective layer (17), i.e. a PSS layer (17). Such a layer is located below a new ballast bed (18) to be produced in order to construct a rail. The PSS layer (17) is made water-tight by spraying a multicomponent mixture of resins in gel form in a program-controlled manner and adding water and selectively one activator or a retarder. This process is preferably carried out within a track construction train as a sub-function thereof. Such a mixture is applied in a computer-controlled manner with a selected uniformity of the coating per unit of surface area and with a selected insertion depth over the entire PSS layer (17) such that the water tightness can be reliably and certifiably ensured. The invention advantageously includes an adhesive carriage (14). An application device is constructed thereon, comprising containers for the components of the mixture as well as all of the elements for precisely mixing and pumping the mixture to a spray unit (25) with spray beams (20-23) and spray nozzles (24).

Abrégé

The device for discharging multi-component adhesives consisting of at least two fluid components (A, B) onto a granular ballast bed (6) of a railway rail section (4) consists of at least two separate carriages, preferably three carriages (1, 2, 3). The carriages can be loaded into a vehicle or a trailer (48) by only two people in that the interior of the vehicle or the trailer is equipped with rails (50, 51) on which the carriages (1, 2, 3) can be rolled. Thus, the carriages can be transported on roadways so as to be brought to the location of use quickly and be put into operation, wherein the carriages are placed on the tracks (4) of the railway from the trailer (48) via retractable rails (51). The device allows adhesives to be applied onto a ballast bed (6) over long distances in a fully automated manner such that all specifications are met and the ballast bed is adhered such that normal train traffic can continue. The entire device can be loaded, transported, unloaded on-site, and put into operation by only two people.
