Embodiment Construction

[0023] exist figure 1 The railway track arrangement 10 shown in FIG. 2 has a track bed 12 on which a plurality of sleepers 14 are placed. The crossties 14 support two rails 16 which are arranged at a distance from one another corresponding to the intended gauge. The area between two ties 14 is called the "crossie box". The sleepers 14 are placed on the track bed 12 in the bearing region 18 . Next to the crossties 14 , the track bed 12 has a shoulder 20 oriented approximately horizontally. A ramp surface 22 running substantially obliquely upwards or in most cases downwards adjoins the shoulder 20 . exist Figures 2 to 5 The adjusting device 24 shown in can blow tempered air between the rails 16 and in the shown embodiment on both sleeper boxes in the blowing area 26 . Around the blow-in region 26 , the regulating device 24 can prevent the tempered air from flowing out of the ballast bed 12 in the covering region 28 .

[0024] as in figure 2 As shown in , the adjusting d...

Abstract

Conditioning device (24) and method for drying and / or controlling the temperature of a ballast bed (12) of a railway track system (10), wherein the railway track system (10) has sleepers (14) resting on the ballast bed (12) and rails (16) resting on the sleepers, wherein the conditioning device has a bogie (30) for moving the conditioning device (24). An outlet nozzle (36) for blowing temperature-controlled air into the ballast bed (12) via at least one blowing-in region (26) positioned between two adjacent sleepers (14) is connected to the bogie (30), as is at least one cover plate (42) for essentially air-tight coverage of an upper side, pointing essentially in the direction counter to the direction of gravity, of a side strip (20), provided next to the sleepers (14) in the direction of travel, of the ballast bed (12). In a method for drying and controlling the temperature of a ballast bed (12) of a railway track system (10), an upper side of the ballast bed (12) and / or at least one sleeper (14) and at least one rail (16) are sealed in an essentially air-tight fashion outside a blowing-in region (26) before temperature-controlled air is blown into the ballast bed (12) via the blowing-in region (26).

Description

technical field [0001] The invention relates to a conditioning device (Konditioniervorrichtung) and method for drying and tempering of a track bed (Schotterbett), by means of which the track bed (Gleisbett) of a railway track installation (Eisenbahngleisanlage) can be dried and tempered so that the subsequent The track bed is at least partially foamed. Background technique [0002] In order to be able to stabilize the track beds of railway track installations and to be able to remove high loads, it is known, for example, to foam-fill cavities of the track beds of railway track installations with polyurethane (PU). For this purpose, isocyanate and polyol are sprayed into the cavity of the track bed, where they react to form polyurethane foam. In order to achieve the defined reactions, corresponding reaction conditions need to be established in a defined way in the ballast bed. In particular, the track bed should be as dry as possible and free from water. It is known, for e...
