    专利说明:

    [001] The invention relates to a method for producing a rail track with slab for railway vehicles with an emergency passage for rail vehicles in which a section of the prefabricated rail track with rails and sleepers is supported and positioned on a substructure by means of a support and alignment device and a rail slab is produced by casting in the sleepers.
    [002] Railways with flagstone for railway vehicles are known in the art and are preferably used in tunnels. In order to ensure rapid rescue in the event of accidents and disturbances, such railways are provided, particularly in tunnels, with emergency passages that are actionable for road vehicles and, of course, also accessible to pedestrians. A requirement with respect to the latter is that stumbling points are eliminated as far as possible.
    [003] The known emergency passages consist of prefabricated slabs, for example, of concrete, resting on a concrete slab of the concrete track in which the sleepers blocks are embedded. In the case of railways with elasticly supported, vertically mobile sleepers, an additional requirement is that the emergency crossing plates do not prevent the mobility of sleepers. An advantage of these emergency passages is that the dimensions and weight of the prefabricated plates can be designed so that the plates can be transported and extended by conventional means. However, a disadvantage is that the dimensions of the slabs have to be adapted to the gauge, the dimensions of the sleepers blocks, the spacing of the sleepers blocks, and the slope of the slab of the filling concrete railroad. A slope is required to drain the water. All of these variable parameters become uneconomical to maintain a stock of prefabricated slabs. Another disadvantage of emergency passages of this type is that the plates often do not rest steadily on the slab of the concrete filling rail, so the passing vehicles cause a tilting movement and the plates are thus subjected to high wear local.
    [004] On the basis of this prior art, the objective of the invention is to provide a method for producing a rail track with slab for railway vehicles with an emergency passage for road vehicles that is simple and cost effective to implement and that results in a rail track with a slab provided with a positionally stable emergency passage having a high load capacity.
    [005] According to the invention, this objective is achieved in that the part of the sleepers that protrudes from the rail slab and the rails are separated by formwork elements and an emergency passage is applied to the rail slab by casting.
    [006] In particular, this method offers the advantage that the emergency passage fits precisely on the rail slab and rests on it steadily. In addition, the need to prefabricate, and more particularly, maintain a stock of slabs for the emergency passage is eliminated.
    [007] According to a method modality, the formwork elements are attached before the rail slab is fused. This modus operandi provides the advantage that it is not necessary to step on the rail slab to attach the formwork elements after melting the rail slab and that the emergency passage can possibly be applied before the rail slab have completely hardened.
    [008] According to another method modality, the support and alignment device is removed before the emergency passage is fused. This has the advantage that no part or trace of the support and alignment device remains in the emergency passage.
    [009] The invention also relates to a railroad with a slab produced according to the method of the invention.
    [0010] In a rail-slab type modality, a drainage tube is arranged in the substructure and communicates with the substructure surface through connection openings provided in the substructure at determined intervals. A substructure prepared in this way eliminates the need for the subsequent installation of a drainage system.
    [0011] According to another modality, the rail slab is provided with connection openings that communicate with the connection openings provided in the substructure. It is very simple to provide the rail slab with such connection openings, for example, by inserting the formed parts before the rail slab is fused.
    [0012] According to another modality, the emergency passage is divided by joints extending substantially transversely to the rails. These joints absorb the expansions and contractions of the emergency passage. In addition, this allows easy step-by-step fabrication of the emergency passage according to the length of the prefabricated rail sections.
    [0013] According to another modality, the emergency passage is provided with drainage shafts that communicate with the connection openings of the rail slab. These drainage shafts are preferably arranged in the area of the joints and ensure the drainage of water from the emergency passage.
    [0014] If, according to another modality, the surface of the emergency passage is provided with drainage channels, the drainage of the emergency passage is further improved.
    [0015] According to another modality, the sleepers have a raised shoulder on at least one side of the track whose surface is at least approximately level with the surface of the emergency passage. In this way, gaps in the emergency passage that may otherwise remain after removing the formwork elements are largely closed.
    [0016] The invention still relates to formwork elements to implement the method of the invention. The main purpose of these elements is to allow quick adjustment and removal.
    [0017] According to the invention, this objective is achieved in that the formwork elements consist of hoods that are intended to be fitted over parts of the sleepers and plates connecting the adjacent hoods. These hoods and plates are quickly assembled and dismountable and are, in addition, reusable.
    [0018] According to a form of the formwork elements, the plates are removably connectable to the hoods. This measure also facilitates the assembly and disassembly of the formwork elements.
    [0019] According to another form of formwork elements, the plates are connectable to the hoods so that the spacing between the adjacent hoods is variable. This eliminates the need to provide plates of different lengths according to the different spacing of the sleepers.
    [0020] The exemplary embodiments of the invention will be described in more detail below by way of examples with reference to the accompanying drawings. The latter show:
    [0021] Figures 1 to 6 six steps of a method according to the invention in the respective sectional views taken transversely to the direction of travel,
    [0022] Figure 7 is a perspective view of a pair of formwork hoods,
    [0023] Figure 8 is a perspective view of a rail section with adjusted and interconnected formwork hoods, and
    [0024] Figure 9 is a perspective view of a section of a track with a slab according to the invention.
    [0025] In Figure 1, the initial situation in a modality of the method according to the invention is illustrated by way of example. A section of railway track consisting of a plurality of sleepers 5 and tracks 8 mounted on it is supported and aligned on a substructure 1, for example, of reinforced concrete, by means of a support device and of alignment 4. In the substructure, a drainage tube 2 extends which communicates with the upper side of the substructure 1 through the connection openings 3 arranged at specified intervals. In order to cushion the vibrations produced later when the vehicles are passing over the railroad, a respective rubber shoe 6, on which an elastic insert 7 is arranged, is fitted on the bottom of each block of sleepers 5. As shown in the figure, the sleepers blocks 5 are provided on both sides of the rail 8 with projections projecting upwards 24 whose upper surfaces are accessible for walking or can be activated by road vehicles later on the finished railroad . The invention, however, is not limited to a railroad including sleepers 5 of this type.
    [0026] In the illustration according to Figure 2, a respective formwork cap 9 is fitted over each block of ties 5 whose purpose is to prevent concrete access to the blocks of ties 5 and branches 8 during the subsequent casting of an emergency pass 12 (Figure 5). As another measure, before casting the slab of the rail track 10, the placement of the formwork elements may possibly be required in the area of the lateral edges of the substructure. These formwork elements may consist of known formwork panels and are not shown in the Figures.
    [0027] Figure 3 shows the situation after the casting of the rail track 10, which may, for example, consist of unreinforced concrete. Basically, the formwork hoods 9 can be adjusted after casting the rail slab 10 as well. However, adjusting them beforehand, as shown in the Figures, offers the advantage that it is not necessary to step on the rail slab 10 to adjust the formwork hoods 9. The rail slab 10 has cone openings Connection 11 for drainage, which are arranged at determined intervals and aligned with the connection openings 3 mentioned with reference to Figure 1. The connection openings 11 can be obtained in a known way by inserting the corresponding parts.
    [0028] Figure 4 differs from Figure 3 only in that the support and alignment device 4 was removed in the stage according to Figure 4. Starting from the situation described in Figure 4, an emergency passage 12 can now be fused as illustrated in Figure 5. Unreinforced concrete can be used for emergency passage 12 as well.
    [0029] Figure 6 shows the condition of the rail track after the removal of the formwork hoods. Crosswise to the railway, the emergency passage 10 is divided into blocks, and a joint is arranged between two respective blocks of the emergency passage, as will be clearer below in the description of Figure 9. The drainage shafts 23 are arranged between two respective blocks of the emergency passage and aligned with the underlying connection openings 11.
    [0030] In addition, it is clearly visible in Figure 6 that the ridges 24 of the sleepers blocks 5 are flush with the surface 25 of the emergency passage 12. Thus, the gaps as they can remain in the emergency passage 12 in the case of conventional sleeper blocks without high lugs after the removal of the formwork hoods, they are closed by the lugs 24 to an extent where the risk of accidents is greatly eliminated.
    [0031] Figure 7 shows a pair of formwork hoods 9 in a perspective view. Each formwork hood 9 has two side walls 13, 15, a rear wall 14, and a top wall 16 and is open on the side facing rail 8. On both side walls 13, 15, the pieces 17 with the nut screws 18 are arranged, which are intended to fix a connection plate 19 (Figure 8). The formwork hoods 9 can consist of sheet metal, synthetic material, wood, or other suitable material. To allow the formwork hoods 9 to be removed by adjusting them outside after the concrete in the emergency passage 12 has hardened, they are slightly tapered in shape. This means that the side walls 13, 15 and the rear wall 14 are inclined about 3 degrees from the vertical so that the formwork hood tapers from the top to the bottom.
    [0032] Figure 8 shows a section of a track 8 with three sleepers blocks 5 covered with formwork hoods 9. Also visible in this Figure are the connection plates 19 each connecting two respective formwork hoods 9. To fix the connection plates 19 to the connection parts 17 of the cooling hoods 9, the connection plates 19 are provided with openings 20 in which bolts 18 provided on the connection parts 17 engage. The connection plates 19 serve to prevent the concrete from the emergency passage 12 from reaching the track 8 while it is still in the fluid state. With respect to connection plates 19, different forms of formwork hoods 9 can be contemplated. Thus, instead of the connecting pieces 17, grooves can be provided on the side walls 13, 15 of the formwork hoods 9, into which the connecting plates 19 can be inserted. Also, two short connecting pieces can form an elongated gap between them, which has the same function as the grooves. Alternatively, the connection plates 19 can be permanently connected to the respective formwork hoods 9 and extend to the adjacent formwork hoods 9.
    [0033] Figure 9 shows a perspective view of a section of railroad. From the bottom to the top, substructure 1, the rail slab 10, and the emergency passage 12 are visible. It is also clearly visible that a gap is left between the emergency passage 12 and the sleepers blocks 5 and the rails 8. The shoulders 24 of the sleepers blocks 5 are substantially flush with the surface of the emergency passage 12 so that no opening greater remains in the emergency passage at these locations, which may result in a risk of accidents particularly for pedestrians. Between two respective sections of the emergency passage is a joint 21, and a drainage channel 22 extends centrally between the tracks 8 in parallel to the last one. Between the two respective sections of the emergency passage 12, a vertical drainage shaft 23 is formed within which the drainage channel is opened. The drain shaft 23 is connected to the drain pipe 2 connecting connection openings 3 and 11 (see, for example, Figure 6).
