Definitions
- the invention relates to a superstructure with concrete sleepers for rail traffic.
- sleepers made of steel have also become known, in order to avoid permanent deformation of the same, which are used with relatively high wall thicknesses.
- these thresholds do not have the desired damping characteristics as wooden sleepers, and only small forces, e.g. B. against the lateral and longitudinal displacement, are applied to the ballast bed.
- sleepers consists of plastic, in particular polyurethane, these sleepers essentially being in the form of wooden sleepers have u. because of the material, mostly foamed polyurethane cross-linked in three spatial directions, has a relatively high strength. However, there are large differences in strength between the homogeneous skin, which is on the outside of the threshold, and the inside, which has a porous structure. The damping can be created in the desired value using different polyurethane materials. In addition to the high cost of such sleepers, the disposal of the thermosetting plastic is particularly difficult here.
- the highly toxic hydrocyanic acid can arise, for example, under unfavorable conditions, so that here too the question of disposal of sleepers which have become unusable can only be solved in a complex manner.
- sleepers of polyurethane foam are used in a ballastless superstructure, the sleepers resting on rubber shoes in corresponding recesses in the sub-concrete.
- Concrete sleepers in particular prestressed concrete sleepers, have a particularly high mechanical stability. In order to make the concrete sleepers even more mechanically stable, they can be prestressed. Such a prestress is applied via reinforcement, in particular steel reinforcement, so that compressive stresses are applied to the threshold, which must be compensated for when tensile stresses occur, in order to then apply the remaining tensile forces to the concrete sleeper.
- Such concrete sleepers can be used in a superstructure made of ballast or ballastless superstructure. The advantages of a superstructure with ballast are that on the one hand the suspension characteristics, i.e.
- the deflection of the Rail is carried by the ballast bed under load, whereas it is precisely this deflection on trains at higher speeds and the kinetic energy increases with the square of the speed that leads to premature destruction of the ballast bed, so that a regular replanting is necessary.
- Such concrete sleepers can also be used in a ballast-free superstructure, although a layer must then usually be provided between the underlay concrete and the concrete sleeper, which enables both the dynamic driving behavior of the entire superstructure and additionally the transmission of structure-borne noise from the wheel to the Should dampen the rail, from the rail to the threshold, and from this to the superstructure, as possible.
- a disadvantage of such an intermediate layer is that on the one hand the forcibly provided grooves of mineral dusts be laid so that the desired suspension characteristics change within a very short time and that with the required relatively thin-walled design, especially in contact with the ballast bed, only an extremely short service life can be achieved, which is reduced by the grooves, at which points Wall thickness is conditional, is further shortened.
- the present invention has set itself the goal of creating a superstructure with concrete sleepers, which has a long service life, which allows less radiation of airborne and structure-borne noise. Furthermore, a dynamic suspension characteristic is to be achieved, which ensures a certain minimum or maximum deflection even with different loads on the tracks.
- the superstructure according to the invention with concrete sleepers for rail-bound traffic the concrete sleepers with at least two rails - for. B. are releasably connected via rail nails, base plates and rubber-elastic inserts and the concrete sleepers on at least one rubber-elastic intermediate layer on the base, z. B. ballast bed, sub-concrete, rock, consists essentially in the fact that the intermediate layer, on which the sleepers, preferably entirely, are in the middle and / or directly, is made of a composite material, which with parts of tires, for passenger cars and / or trucks is built, the fabric reinforcement, in particular made of steel, for. B. steel cord, steel mesh, and are connected with a rubber-elastic binder.
- Concrete sleepers have the advantage that they have a long service life, the receptacles for screws as required for the releasable fastening of rails are particularly resistant can be formed by appropriate deposits in the threshold. If desired, the concrete sleepers can also be preloaded so that they are not only resistant to compressive but also to tensile stresses. If the sleepers lie, in particular entirely, on an intermediate layer which is formed from lumpy material, the spring property of this intermediate layer is less caused by the binding agent between the individual pieces than by mutual wedging, so that the rubber-elastic binding agent does less the task has to absorb forces as to ensure a minimum dimensional stability of the intermediate layer.
- the intermediate layer additionally contains rubber granules with a grain size of 2.0 mm to 30.0 mm, in particular 5.0 mm to 12.0 mm, then both the size of the materials used for the construction of the intermediate layer and, if appropriate, the hardness, a particularly easy one Variation can be carried out, which, for example, allows the route to be adapted particularly easily to the different requirements, whether in the high-speed range or in the range of changes.
- binding agent for the intermediate layer is not foamed, a particularly good non-positive bond can be achieved between the individual sections of the tire and the rubber granulate, with a particularly good permeability to surface water.
- the binding agent for the intermediate layer is foamed, a desired particularly poor conduction of the sound can be achieved due to the different sound densities of the materials.
- the sections of the tires are irregularly shaped, similarly to a ballast bed, there is a particularly advantageous mutual support of the tire sections, as a result of which the desired dynamic suspension characteristics can be obtained in a particularly simple manner.
- the sections of the tires for the intermediate layer have a grain size between 50 mm and 100 mm, then there is an optimization between the properties of the intermediate layer and the tire sizes usually available and thus maximum grain sizes.
- a particularly advantageous mutual support and service life of the intermediate layer is given when the thickness of the intermediate layer is approximately half to three times the largest grain size of the sections of the tires.
- the concrete sleepers rest on a liquid-permeable fleece, in particular made of plastic fibers, e.g. B. from polypropylene, on an intermediate layer, on the one hand, a derivation of surface water can be carried out, on the other hand, a forwarding of mineral and organic particles is avoided.
- a liquid-permeable fleece in particular made of plastic fibers, e.g. B. from polypropylene
- a derivation of surface water can be carried out, on the other hand, a forwarding of mineral and organic particles is avoided.
- This is not only important for the durability of ballast beds, but also for underground concrete.
- Synthetic fiber nonwovens made of polypropylene are characterized by their special chemical and mechanical stability.
- the asphalt bed preferably having an upwardly extending continuous wall on both sides of the ends of the sleepers, then a receptacle for both the intermediate layer and the sleepers created, while at the same time a forwarding of structure-borne noise is reduced due to the insulating properties of asphalt.
- the asphalt bed has a thickness of 0.2 to 1.0 times that of the sleepers, then a particularly favorable adjustment of the force absorption and low Transmission of the sound guaranteed.
- the wall of the asphalt bed has interruptions, which preferably extend to the support surface of the intermediate layer, for the drainage of surface water, then the surface water can not only be drained vertically downwards, so that the asphalt bed is porous, but also laterally.
- Such lateral drainage of a track superstructure is particularly important in frost periods when the through channels and pores in the subsurface are closed by frozen water.
- both the intermediate layer and the side and end faces of the concrete sleepers are at least partially surrounded by gravel, this provides a particularly favorable support of the concrete sleepers to one another, and the radiation of airborne noise can also be kept particularly low.
- each concrete sleeper is assigned its own intermediate layer, whereby gravel is preferably arranged between the sleepers and the intermediate layers, material placement can be saved if the concrete sleepers are positioned exactly on the subsurface, as is the case, for example, on a rocky subsurface, particularly leveled ballast bed or concrete subsurface be carried out, in addition, a discharge of surface water is also particularly easy.
- the arranged ballast also minimizes airborne noise emissions in a simple and effective way.
- a concrete sleeper carries two releasable fastenings for rails, whereby the concrete sleeper itself can usually be prestressed via steel inserts (not shown).
- FIG. 2 an intermediate layer is shown in section.
- the sections 10 made of car tires have a maximum extension of 95 mm.
- the binder 11 surrounds the sections of the tires on their surface, so that in addition to the mutual stiffening and clawing through the steel inserts of the tire sections, the same binds to one another via the binder.
- An elastic polyurethane made from a prepolymer Desmodur E 41 with hardener 0 Z from Bayer AG is used as the binder.
- An intermediate layer according to Fig. 2 is obtained as follows.
- 100 kg of tire pieces with a grain size of 50 mm to 100 mm are mixed with 10 kg of the rubber-elastic binder mentioned above. This mixture is then placed in a plate press and made to harden. Such a mixture has a weight of 700 kg per m3. Intermediate layers with a density of 600 kg to 1,300 kg per m3 are particularly suitable, the density of around 1,000 kg per m3 being a preferred size.
- the pieces of tire are obtained in such a way that for the time being the beads, that is, those circular steel inserts, which one Allow the exact fit of the tire on the rim to be removed, after which the tires are cut into quarters. These quarters come into a shredder. If an increase in the density is desired and a consequent change in the spring characteristics, either more binders, e.g. B. also in foamed form and also in addition to the tire pieces other rubber particles, in particular with a grain size between 5.0 mm to 12.0 mm, as they occur, for example, in the manufacture of carcasses for retreaded tires.
- binders e.g. B. also in foamed form and also in addition to the tire pieces other rubber particles, in particular with a grain size between 5.0 mm to 12.0 mm, as they occur, for example, in the manufacture of carcasses for retreaded tires.
- a rubber-elastic binder is a cycloaliphatic elastically modified epoxy resin based on bisphenol A.
- the superstructure shown in FIGS. 3 and 4 has a ballast bed 12 on which an asphalt bed 13 rests.
- This asphalt bed 13 has walls 14 which are guided along the end faces of the concrete sleepers 1.
- the walls serve as a kind of support surfaces and are also covered by the ballast of the ballast bed 12.
- interruptions 15 are provided in the walls, which extend as far as the bearing surface 16 of the intermediate layer 17.
- the intermediate layer can either have a continuous assignment to a concrete sleeper 1, as shown in broken lines in FIG. 4 or, as shown in broken lines in FIG. 4 and shown in FIG. 5.
- the thickness d 1 of the asphalt bed is 9 cm
- the thickness d 2 of the intermediate layer is 7 cm
- the thickness d 3 of the concrete sleeper 1 is 26 cm.
- a large number of the concrete sleepers can also rest on gravel on the intermediate layer, which in turn rests on another ballast bed.
- FIG. 6 The diagram shown in FIG. 6 for the spring characteristic of an intermediate layer of the superstructure according to FIG. 2 shows that compression is given even at lower loads on the superstructure, so that the superstructure does not behave like a rigid body even in unladen wagons , but compresses. At higher loads, there is then a greater deflection, with the relative compression decreasing.
- a fleece for example made of polypropylene fibers, can also be arranged instead of the asphalt bed.
- a fleece for example made of polypropylene fibers, can also be arranged instead of the asphalt bed.
