Description

The subject invention relates to a method for the construction of a rail track for railroads and the like., Which laid two spaced apart track track rails on a ballast layer and the rails are brought by plugging the ballast layer in their horizontal and vertical positions.
Furthermore, the subject invention relates to a rail track produced by this method.

It is known for the construction of rail tracks for railroads two rails to sleep on wooden or concrete sleepers, which are laid on a ballast layer to secure. The fixation of the rails set in their horizontal and vertical positions is carried out by plugging the ballast layer located below the thresholds. Since this process is performed by machine, it is inexpensive.

However, rail tracks produced by this method are disadvantageous because the rails represent two carriers which rest on the sleepers at spaced locations. Since therefore the rails can move between the bearings in the vertical direction, this vibration and noise emissions are caused. Another disadvantage is that change due to the vibrations occurring due to the railway operations, the layers of the thresholds, which is why it is necessary to constantly check the horizontal and vertical positions of the rails and the rails by plugging the underlying gravel layer turn into the required To bring layers.

It is also known to fix rails on so-called solid lanes, namely laid on the ground concrete slabs or on concrete surfaces. Since the positions of these concrete slabs or concrete surfaces are not changed by the driving operation, there is no need to bring the rails periodically in the correct positions. However, since the rails are also stored on so-called fixed lanes only at discrete points, also occur in the train operation vibration and noise emissions caused by vibrations. The circulation of the rails at mutually spaced locations is therefore necessary in order to be able to adjust the rails in the required due to the course of the route altitudes and inclinations. In addition, this manufacturing process is therefore very expensive, since the adjusted positions of the rails must be manually fixed.

The subject invention is therefore based on the object to provide a method for the construction of a rail track, by which the disadvantages of the known methods are avoided. This is inventively achieved in that in the ballast layer two strands of mutually spaced concrete elements, which are formed over part of their length with projections, are laid, that are arranged on the concrete elements in the longitudinal direction of the rails steel plates that the two rails at a distance of the track from each other on the steel plates are attached with play, that the rails are brought by plugging the ballast layer located below the concrete elements in the required horizontal and vertical layers, that the ballast layer is solidified by introducing a binder that between the concrete elements and the Steel plates a leveling layer is introduced and that after setting the rails in their horizontal and vertical positions, the steel plates are rigidly attached to the concrete elements and the rails to the steel plates.

Preferably, the two strands of the concrete elements are connected to each other by means of struts. Furthermore, the concrete elements forming the two strands preferably directly adjoin one another in the longitudinal direction. They can be formed at their front ends with mutually opposite projections and recesses. Preferably, the concrete elements are formed at one of their front ends with a projection located in the lower region and at the other end face with a projection located in the upper region. Furthermore, the adjoining concrete elements can be connected to each other by means of bolts.

According to a further preferred method, the concrete elements are formed in a U-shaped cross section, wherein they with a lower, resting on the ballast base plate and with two of the bottom plate upwardly projecting in Formed longitudinally of the strand extending and spaced apart beams are formed, between which the rails are laid.

According to a further preferred feature, the steel plates running on the strands of the concrete elements in the longitudinal direction of the rails are laid in such a way that the joints of the steel plates are offset with respect to the joints of the concrete elements. Furthermore, a layer of an elastic material is preferably arranged below the rails located on the steel plates. Finally, the rails are fastened to the steel plates by means of bolts, the rigid attachment only taking place once the rails have been adjusted in their lateral and vertical positions.

In a rail track produced by the method according to the invention concrete elements laid in a ballast layer are provided, the ballast layer is solidified by a binder, are mounted on the concrete elements in the direction of the strand running steel plates, the rails are attached to the steel plates and located between the steel plates and the concrete elements a leveling layer. Preferably, further between the rails and the steel plates is an elastic damping layer.

The fastenings of the steel plates 4 on the concrete elements 3 and the rails 6 on the steel plates 4 are explained below with reference to FIGS. 5 to 8:

• As can be seen from Figure 5, the steel plates 4 are placed on the concrete elements 3, wherein they rest directly on the projections 33 and are secured to the concrete elements 3 by means of a first group of screws 41. The steel plates 4 are compared to the concrete elements 3 offset so that they rest in their central regions on the projections 33 and their ends in the middle Are areas of concrete elements 3. Below the rails 6, the damping layer 5 is located.
• As can be further seen from Fig.6, is in those areas in which the steel plates 4 do not rest on protrusions 33, between the concrete elements 3 and the steel plates 4 a leveling layer 7. In addition, the steel plates 4 in these areas by means of a second Group of screws 42 attached to the concrete elements 3.
• As can be further seen from Fig. 7, the rails 6 are fixed by means of the brackets 61 and the screws 62 to the steel plates 4, which is in these areas between the bottom plates 31 of the concrete elements 3 and the steel plates 4, the leveling layer 7.
• From Figure 8, a projection 33, the leveling layer 7, the mounting screws 41 and 42 for the steel plates 4 and the brackets 61 and the mounting screws 62 for the rails 6 can be seen over the course of the route.

The erection of such a rail track is carried out as follows:
On a gravel layer 2 located on a solid substrate 1, two strands of concrete elements 3 running along the route are laid. The paired concrete elements 3 of the two strands are held by means of the struts 35 from each other at the required distance. The successive concrete elements 3, which are formed at their end faces with the mutually associated projections 3a and recesses 3b and which close directly to each other, are initially connected by means of bolts 34 so that they are still movable. Hereupon, steel plates 4 extending in the longitudinal direction of the concrete elements 3 are placed on the concrete elements 3 between their mutually parallel bars 32, which steel plates rest on the projections 33 located on the bottom plates 31 of the concrete elements 3. The steel plates 4 are placed on the concrete elements 3 so that they are approximately centrally offset. As a result, the steel plates 4 rest on the projections 33 of the concrete elements 3 only in their middle region. As a result, the steel plates 4 are rigidly fastened to the concrete elements 3 by means of the first group of screws 41.

Thereafter, the rails 6 are placed on the steel plates 4 with the interposition of the elastic layer 5 and secured thereto by means of the clamps 61 and the bolt 62. As a result, the below the concrete elements 3 located ballast layer 2 is stuffed in a conventional manner, whereby the rails 6 are brought into their horizontal positions. Then the ballast layer 2 through Introducing a binder, such as a cement paste or a plastic agent, solidified, whereby the thus solidified ballast layer fulfills the function of a so-called fixed carriageway. Furthermore, existing between the steel plates 4 and the concrete elements 3 spaces are filled by the leveling layer 7. Finally, the second screws 42 are tightened, whereby the rails 6 are rigidly secured to the concrete elements 3.

By the method according to the invention, a rail track can be built, which has the properties of a solid roadway, but the disadvantages associated with the production of a rail track on a fixed track are avoided.

In this case, the rails 6 can be adjusted in a conventional manner in their horizontal and vertical positions. Since the ballast layer 2 is solidified after setting the required layers of the rails 6 by a binder, it forms a so-called solid lane, which requires a much lower maintenance than a non-solidified ballast layer. Since the rails 6 rest over their entire course on the steel plates 4 and the steel plates 4 rest due to the leveling layer 7 over its entire length on the concrete elements 3, also caused by discretely mounted rails vibration and noise emissions are avoided. The side of the rails 6 located bar 32 of the concrete elements 3 also form a derailment and sound insulation.
