Description

The invention relates to a solid roadbed for rail vehicles with rails mounted on sleepers located in an artificial structure made of concrete or reinforced concrete.
A solid roadway passing through an artificial structure, such as a bridge, currently requires relatively high costs for its construction. The design guidelines for a solid roadway require that the sleepers be located on a slab of the upper structure. This plate of the upper structure lies on a plate with protrusions for transmitting horizontal forces. In turn, the slab with protrusions is located on a protective slab of concrete, which, at least on one side, can abut the edge segment of the bridge structure to transfer lateral forces from the solid roadway to the bridge structure. The regulations further require that the bottom of the concrete backing plate be hermetically sealed. Different layers of such a solid roadway on the bridge can have a total thickness of 80 cm or more, therefore, such a roadway requires large construction costs and leads to a relatively high cost.
In the publication DE 19723587 A1, an artificial structure has already been proposed, for example a bridge with a solid roadway, in which the sleepers are located either on a continuous supporting rib or on separate protrusions arranged in a row. In the manufacture of the first form the base plate of the bridge structure, which is then poured into the second base plate for a durable roadway. A separate operation involves concreting on the upper bearing plate of the supporting ribs or protrusions on which the sleepers for rails are mounted. Although this design can provide some simplification, it still requires large construction costs, since the artificial structure is produced as a result of a series of sequential operations. Moreover, it is especially costly to produce protrusions or supporting ribs that require subsequent concreting.
Therefore, the aim of the invention is the creation of a solid roadway for rail vehicles of the above type, the manufacture of which is simplified and, therefore, cheaper.
The solution to this problem for a solid roadbed of the aforementioned type according to the invention provides that the sleepers are poured into building concrete of an artificial structure or in a protective concrete layer or laid directly on building concrete or on a layer of protective concrete.
According to the invention, the roadway, in which the sleepers are poured, is made simultaneously with the manufacture of the artificial structure, and, unlike the known hard roadway, the subsequent laying of the roadway plate is eliminated, which saves both material and cost.
The invention is based on the understanding that concrete of load-bearing structures of an artificial structure or a protective concrete layer available on an artificial structure can serve simultaneously as a slab of the roadway, since sleepers are embedded in it in the manufacture of concrete of load-bearing structures or a protective concrete layer. Equally, sleepers can be laid on concrete for load-bearing structures or a protective concrete layer. Concrete for load-bearing structures or a protective concrete layer, respectively, satisfy all the structural requirements for a roadway slab in the case of a hard roadway. Therefore, a separate slab of the roadway or a slab of the upper structure can be excluded and, accordingly, a separate work step is eliminated, so that the structure according to the invention has a particularly simple structure and is associated with lower material costs.
Particularly preferred is that the sleepers of the solid roadway are monoblock or multiblock sleepers. This type of sleepers covers all mainly used sleepers. The sleeper blocks are interconnected by means of lattice beams and flooded in the manufacture of an artificial structure, so that a monolithic solid roadbed is obtained.
In the solid roadway according to the invention it can be provided that it is provided with longitudinal and / or transverse reinforcement. With this arrangement of reinforcement, the number of reinforcing bars can be optimized, since the reinforcement already available in the artificial structure can also be used for solid roadbed.
In an artificial structure made in the form of a bridge, it can be provided that the bridge has at least one edge segment and / or at least one cable channel located laterally next to the sleepers for receiving lateral forces. Due to the edge segment or the cable channel, the forces acting on the side relative to the direction of the roadway are transmitted to the supporting structure of the artificial structure. Thus, it is possible to abandon other complex structural elements, such as protrusions or supporting ribs. It is also possible that the artificial structure is a concrete slab with a base.
Due to the fact that the sleepers of the solid roadway according to the invention are poured in the protective concrete layer of the bridge, this protective concrete layer can successfully serve simultaneously as a waterproofing of the bridge, so that additional waterproofing of the bridge deck can be abandoned.
The solid roadway according to the invention can also be used in an artificial structure made in the form of a tunnel, while the sleepers are poured directly into the leveling layer of concrete. Since here it is also possible to refuse additional, separately manufactured slabs of the roadway, the required inner diameter of the tunnel pipes will be smaller.
Other advantages and details of the invention are explained based on an exemplary embodiment with reference to the drawings. In the drawings, in a schematic representation, are shown:
figure 1 is a first example implementation of a solid roadbed according to the invention on a bridge structure in perspective view;
figure 2 is a second example of the implementation of a solid roadway according to the invention, in which the sleepers are poured in a protective concrete layer;
figure 3 is an enlarged cutout of the solid roadway of figure 2 with a partially presented protective concrete layer;
4 is a third example implementation of a solid roadway according to the invention in a tunnel, and
5 is a fourth embodiment of the invention.
Figure 1 shows a sectional and perspective view of a bridge structure 1 with a solid roadway 2. The solid roadway 2 is made integral with the supporting structure 3 of the bridge structure 1. On both sides of the solid roadway 2 there are cable channels 4 and edge segments 5. Cable channels 4 and edge segments 5 serve to transfer lateral forces from a solid roadbed 2 to the supporting structure 3.
The solid roadbed 2 includes two-unit sleepers 6, which carry the rails 7. In the illustrated embodiment, the sleepers 6 are directly poured into the concrete of the supporting structure 3, there is no separate slab of the upper structure or the plate of the roadway. In the plane of the section, rods of longitudinal reinforcement 8 are visible, in addition to them there are reinforcing rods forming transverse reinforcement.
Figure 2 shows a second embodiment, wherein the building elements matching the building elements of the first embodiment are denoted by the same reference numerals.
In contrast to the first embodiment, in the bridge structure shown in FIG. 2, sleepers 6 are poured into a protective concrete layer 10 located on the supporting structure 11 of the bridge structure 9. For the manufacture of the bridge structure 9, the supporting structure 11 is first formed, then the cable channels 4 are installed and edge segments 5. The sleepers 6 are placed in a trough-free space between the cable channels 4 or, respectively, the edge segments 5 and are installed in a precisely provided position. Reinforcement 8 is installed in the same way. The production of a protective concrete layer 10 is carried out by pouring concrete. The protective concrete layer 10 can equally serve as a waterproofing of the bridge.
Figure 3 shows an enlarged cutout of the solid roadway depicted in figure 2 with only a partially protective concrete layer.
Figure 3 two-unit sleepers 6 are presented before pouring. Accordingly, two sleepers 12, 13 are interconnected by means of lattice beams 14, which also serve as transverse reinforcement. Between the lattice beams 14 there are reinforcing bars 15 in the transverse direction, as well as rods of longitudinal reinforcement 8. After laying and aligning the sleepers 6 and reinforcement, pouring is performed, so that only the upper areas 16 of the two-unit sleepers 6 protrude from the concrete layer.
Figure 4 shows a sectional view of a third embodiment of a solid roadway in a tunnel. Two-unit sleepers 6 are poured directly into concrete 16 of the supporting structures of the tunnel, that is, a solid roadway 17 is connected integrally with concrete 16 of the supporting structures of the tunnel. In the plane of the section, rods of longitudinal reinforcement 18 are visible. Since there is no additional or separate slab of the roadway, the diameter of the tunnel may be insignificant.
In the manufacture of solid roadway 17 in the tunnel, two-unit sleepers 6 are first laid and adjusted, and then concrete 16 of the supporting structures is poured.
Figure 5 shows another example of the implementation of a solid roadway in the tunnel.
In contrast to the embodiment shown in FIG. 4, a leveling concrete layer 19 is provided in which the sleepers 6 are embedded. Below the leveling concrete layer 19 is a concrete layer 20 in the form of circle segments. Thus, the forces arising from the operation of a solid roadway are diverted directly to the base of the tunnel.
