Description

The invention relates to a method for producing a solid track for rail vehicles with an escape route for road vehicles according to claim 1. Solid tracks for rail vehicles are known and are preferably installed in tunnels. So that can be helped quickly in accidents and breakdowns, such lanes are equipped in particular in tunnels with escape routes, which are passable by road vehicles and of course accessible by pedestrians. For the latter, there is a requirement that there are no stumbling blocks possible.

Known escape routes consist of prefabricated panels, for example made of concrete, which rest on a deck made of filled concrete, in which the threshold blocks are embedded. In the case of carriageways with elastically mounted, vertically movable sleeper blocks, there is also the requirement that the plates of the rescue route do not hinder the mobility of the sleeper blocks. An advantage of such escape routes is that the dimensions and the Weight of the prefabricated plates can be designed so that the plates can be transported and laid by conventional means. A disadvantage, however, is that the dimensions of the plates must be adjusted according to the gauge, the threshold block dimensions, the threshold block spacing and the gradient of the concrete slab track plate. A gradient is necessary for the discharge of water. All these variable parameters make stock keeping of prefabricated panels uneconomic. Another disadvantage of this type of escape routes is that the plates often do not rest stably on the Füllbeton-deck slab so that they run when driving a tilting movement and are thus subject to local heavy wear.

There are also solid lanes with a rescue route, in which the emergency route was applied by pouring on the deck slab. In the documents DE 20 2009 008 365 U1 . DE 20 2009 008 366 U1 and US 1,745,747 described lanes are used permanent formwork, which are integrally connected in one case with the thresholds and in the other case consist of a hardenable mass which surrounds a portion of the sleepers and the rails. As a result, the above-mentioned requirement that the escape route should not hinder the mobility of the threshold blocks can not be fulfilled. In the document DE 20 2008 008 157 U1 is described an embodiment in which the rescue route is poured with the aid of unspecified and not shown formwork. However, the lying next to the rails areas of the thresholds are connected to the rescue route, so that this roadway can not meet the above requirement.

Based on this prior art, the present invention seeks to provide a method for producing a solid track for rail vehicles with a rescue route for road vehicles, which is simple and inexpensive executable and results in a roadway with a stable and resilient rescue route.

This object is achieved according to the invention that a rubber boot is placed on the threshold blocks before pouring the rescue route from below, in which an elastic insert is arranged that the formwork means over removable areas of the threshold blocks to be set hoods and adjacent hoods, removable plates and be removed after applying the rescue route, so that the escape route to the threshold blocks and the rails leaves a gap.

By this method is achieved in particular the advantage that the rescue route fits exactly on the deck plate and rests stable on this. In addition eliminates the prefabrication and especially the storage of plates for the rescue route.

According to one embodiment of the method, the formwork means are applied prior to casting the deck slab. This approach has the advantage that after the Pouring the slab this must not be entered for attaching the formwork and that, if necessary, the emergency route can be applied before the deck is fully cured.

According to a further embodiment of the method, the carrying and straightening device is removed before the escape route is poured. This has the advantage that in the escape route no parts or traces of the carrying and straightening device remain.

The invention also describes a solid roadway produced by the method according to the invention.

According to one embodiment of the road, a drainage line is arranged in the substructure, which is connected by existing at intervals in the substructure connecting openings with the surface of the substructure. Such a prepared substructure saves a subsequent attachment of a drainage system.

According to a further embodiment, connection openings are present in the carriageway plate, which communicate with the connection openings present in the substructure. Such connection openings are very easy to install in the deck slab, for example by inserting moldings before casting the deck slab.

Another embodiment provides that the escape route is divided by extending substantially transversely to the rails joints. These joints compensate for stretching and shrinkage of the rescue route. In addition, in this way, the escape route easily according to the length the prefabricated track sections are produced step by step.

According to a further embodiment drainage shafts are present in the rescue route, which communicate with the connection openings of the carriageway slab. These drainage shafts are preferably arranged in the area of the joints and ensure the drainage of water from the rescue route.

If, according to another embodiment, drainage channels are arranged in the surface of the rescue route, drainage of the escape route is further improved.

According to a further embodiment, the threshold blocks on at least one side of the running rail have an elevated shoulder whose surface is at least approximately flush with the surface of the escape route. As a result, gaps in the rescue route are largely closed, which would otherwise remain after removing the formwork.

The invention also describes a formwork agent for carrying out the method according to the invention. In particular, these have the task of being able to set up and dismantle quickly and easily.

This object is achieved according to the invention in that the formwork means consist of plates connecting areas of the sleeper blocks to be set and adjacent hoods. These hoods and panels are quick to assemble and disassemble and also reusable. According to the invention, the plates are detachably connectable to the hoods. This measure also facilitates the assembly and disassembly of the formwork.

Another embodiment of the formwork means provides that the plates can be connected to the hoods in such a way that the distance between adjacent hoods can be changed. This avoids that according to different threshold intervals plates of different lengths must be provided.

In FIG. 1 the starting material of one embodiment of the method according to the invention is shown by way of example. A track section consisting of a plurality of pairs of sleepers 5 and rails 8 mounted thereon is supported by a support and straightening device 4 on a substructure 1, for example reinforced concrete can be made, supported and aligned. In the substructure runs a drainage line 2, which is connected by spaced connection openings 3 with the top of the substructure 1. In order for vibrations to be dampened later when driving on the tracks, a rubber boot 6 is placed on each sleeper block 5 from below, in which an elastic insert 7 is arranged. As can be seen from the figure, the threshold blocks 5 are each provided on both sides of the rail 8 with upstanding shoulders 24, the upper surface can later enter the finished lane or be driven by road vehicles. The invention is not limited to a roadway with such threshold blocks 5.

In the illustration according to FIG. 2 is on each threshold block 5, a formwork hood 9 is put on, the task is, later in the casting of an escape route 12 ( FIG. 5 ) to prevent the access of concrete to the threshold blocks 5 and the rails 8. As a further measure before the casting of the deck slab 10, formworks may have to be installed in the area of the lateral edges of the substructure. These formworks can consist of known formwork panels and are not shown in the figures.

FIG. 3 shows the situation after the casting of the deck slab 10, which may consist of unarmed concrete, for example. The placement of the shuttering hoods 9 before casting the decking plate 10, as shown in the figures, offers the advantage that the decking plate 10 does not need to be entered for placing the formwork hoods 9. In the deck plate 10 are in Intervals connecting openings 11 for drainage exist with those associated with FIG. 1 mentioned connection openings 3 are aligned. The connection openings 11 can be obtained in a known manner by inserting corresponding parts.

FIG. 4 differs from FIG. 3 only in that according to the stage FIG. 4 the carrying and straightening device 4 has been removed. Starting from the in FIG. 4 a rescue route 12 can now be poured, as shown in FIG. 5 is shown. Unarmored concrete can also be used for the escape route 12.

FIG. 6 shows the condition of the roadway after removing the formwork hoods. The rescue route 10 is divided into blocks transversely to the roadway, wherein between each two escape route blocks a joint is arranged, as described below in connection with the description of FIG. 9 becomes even clearer. A drainage shaft 23 is in each case arranged between two escape route blocks and is in alignment with the connection opening 11 present underneath FIG. 6 clearly seen that the shoulders 24 of the threshold blocks 5 are flush with the surface 25 of the escape route 12. As a result, gaps that would remain in the emergency route 12 with the use of conventional threshold blocks without increased shoulders after removing the formwork hoods, so far closed by the shoulders 24 that an accident risk is largely eliminated.

FIG. 7 Each formwork hood 9 has two side walls 13, 15, a rear wall 14 and a top wall 16 and is open at the side facing the running rail 8 side.

On both side walls 13, 15 connecting parts 17 are arranged with bolts 18, which for attaching a connecting plate 19 (FIGS. FIG. 8 ) are determined. The shuttering hoods 9 may be made of sheet metal, plastic, wood or other suitable material. So that the formwork hoods 9 can be removed after curing of the concrete of the escape route 12 by being pulled upwards, they are slightly conical. This means that the side walls 13, 15 and the rear wall 14 are inclined relative to the vertical by about 3 degrees, such that the formwork hood is narrower from top to bottom.

FIG. 8 shows a section of a running rail 8 with three covered by formwork hoods 9 threshold blocks 5. Clearly seen in this figure and connecting plates 19, with each of which two formwork hoods 9 are interconnected. For fastening the connection plates 19 with the connection parts 17 of the shuttering hoods 9, openings 20 are present in the connection plates 19 into which the bolts 18 present on the connection parts 17 engage. The connection plates 19 have the task of preventing the concrete of the escape route 12 from reaching the rail 8 when it is still able to flow. With regard to the connection plates 19, different embodiments of the formwork hoods 9 are conceivable. Thus, instead of the connection parts 17, grooves may be arranged in the side walls 13, 15 of the shuttering hoods 9 into which the connection plates 19 can be inserted. Also, in each case two short connecting parts can form an elongated recess between them, which has the same function as a groove. Alternatively, in each case a connecting plate 19 with a shuttering hood 9 fixed be connected and reach to the adjacent formwork hood 9.

FIG. 9 shows in perspective a section of a roadway. From bottom to top, the substructure 1, the carriageway panel 10 and the rescue route 12 are visible. It is also easy to see that the escape route 12 leaves a gap to the threshold blocks 5 and to the rails 8. The shoulders 24 of the threshold blocks 5 are practically flush with the surface of the escape route 12, so that there are no major openings in the rescue route in their place, which could pose an accident risk, in particular for pedestrians. Between each two sections of the rescue route, a joint 21 is present in each case and in the middle between the rails 8 runs parallel to this a drainage channel 22. In each case between two sections of the rescue route 12, a vertical drainage shaft 23 is formed, in which the drainage channel 22 opens. The drainage shaft 23 is connected through the connection openings 3 and 11 (see, eg, FIG. FIG. 6 ) connected to the drainage line 2.
