Definitions

• the invention relates to a track system for rail-bound vehicles, in particular railways, with a superstructure which has rails mounted on sleepers and a ballast bed supporting the sleepers, the superstructure receiving at least one track in a U-shaped trough made of concrete running in the longitudinal direction of the track system is which has a base plate and on opposite sides upwardly projecting edge caps which laterally support the ballast bed, at least one drain line being provided in the trough for draining the interior of the trough.
• the so-called gravel superstructure has been used as the superstructure in railway track systems, in which the sleepers rest on a ballast bed, which in turn is supported on a substructure, via which the forces exerted by the railway vehicle are dissipated into the ground.
• the ballast track has proven itself because it is highly flexible and adaptable ability and is relatively easy to maintain.
• the gravel superstructure it is necessary to reliably prevent it from being flooded or submerged by any rising groundwater.
• track systems are to be erected in sections of the ground with a high groundwater level, it is therefore necessary and customary to surround the entire traffic area, ie the track system with all auxiliary structures such as side masts, soundproof walls, etc., on the underside with a waterproof concrete tank. Since such a concrete trough is structurally complex and has relatively large dimensions, this procedure involves very high costs. In addition, buoyancy problems often arise with such concrete troughs with increasing groundwater, which make additional anchoring necessary.
• EP 0 663 470 AI shows a track system with a U-shaped trough made of concrete, in which the ballast bed and the tracks are received.
• a large number of drainage openings are formed in the trough on both sides.
• the ballast bed is integrated in a hardening mortar suspension that completely fills the interior of the trough.
• the drain openings must be closed with plugs before they are introduced.
• a monolithic bearing body is formed for the tracks, which drains rainwater superficially without it being able to accumulate in the trough.
• the hardened mortar suspension in conjunction with the cast plugs, prevents the groundwater from penetrating into the trough.
• This construction has the disadvantage that pouring out the entire interior of the trough is very complex and expensive and makes subsequent track corrections difficult.
• the invention has for its object to provide a track system of the type mentioned, in which the
• the drainage line is assigned a closure device which comprises a closure element which is adjustable between an open position and a position closing the drainage line, in which at least the penetration of water is prevented by the drain pipe into the interior of the trough.
• the invention is based on the consideration that the trough serving the lateral support of the ballast bed can also be used as a protective trough against rising groundwater. It is also provided that the water located in the interior of the trough or entering during precipitation is discharged via the drain pipes at a normal groundwater level. However, the entry of water through the drain pipes when the groundwater level rises is prevented if necessary by means of the adjustable closure element.
• edge caps are of course so high in the track system according to the invention that the statistically expected groundwater cannot run into the trough via the edge caps.
• the height and cross-section of the trough is dimensioned such that it rests against buoyancy at all expected groundwater levels without anchoring on the ground.
• a mechanical closure element is preferred according to the invention as a closure device, either manually or with a corresponding drive device either in an open position that releases the drain line or in a position the drain line can be brought into a closed position in both flow directions.
• An adjustable and, in particular, pivotally mounted closure flap has proven to be a closure device.
• you can also control a rack and thread Sliding bulkhead or a check valve may be provided, which allows a water flow directed outwards from the interior of the trough, but prevents an opposite water flow.
• the closure device is assigned a detector device by means of which the current groundwater level in the vicinity of the trough is detected. If the detector device determines that a predetermined limit value of the groundwater level has been exceeded, it either acts directly on the closure element and closes the drain line, but it is preferably provided that the detector device emits a signal which is received by a control unit, whereupon the necessary measure to activate a drive device for closing the closure element or a notification from service personnel, which then brings the closure elements into the closed position.
• a drainage pump is arranged in the trough, by means of which the interior of the trough can be dewatered.
• trough Various configurations are conceivable for the trough according to the invention.
• provision can be made for each track to be accommodated in its own trough, but for cost reasons it should be cheaper to accommodate several adjacent tracks in a common trough.
• drain lines should be arranged on both sides of the trough, ie in both edge caps, each of which can be shut off by means of a closure device.
• FIG. 2 the track system according to FIG. 1 with a high groundwater level
• FIG. 3 shows a cross section through a trough receiving two tracks at normal groundwater level
• Figure 4 shows the track system of Figure 3 with a high groundwater level.
• a track system 10 for a single-track railway line comprises a trough 14 formed of concrete, preferably extending as a continuous band in the longitudinal direction of the track system, which has a base plate 15 supported on a substructure or the ground 22 and attached to it laterally Edge caps 16 protruding above.
• the base plate 15 together with the edge caps 16 forms the U-shaped trough 14 for receiving a ballast bed 13 in the trough interior 24.
• the ballast bed 13 is optionally glued to form a stable ballast body and stores sleepers 11 and rails 12 in a known manner.
• a drain line 17 is provided, through which water which collects in the trough interior 24 during precipitation can flow off laterally, as indicated by the arrow W.
• the bottom surface of the trough interior 24 can be provided with a corresponding transverse incline.
• closure flap 18 On the outside of the edge cap 16 there is a pivotably mounted closure flap 18 which can be brought from the open position shown in FIG. 1 to a closed position in which it completely closes the drain line 17.
• a drainage pump 19 is provided in the trough interior 24, by means of which water can be removed from the trough interior 24 via a line 23 if necessary.
• a detector device 20 is installed to the side of the trough 14, which detects the groundwater level GW in the area surrounding the trough 14 and emits a corresponding signal via a line 21 to a control unit (not shown).
• closure flap 18 is in the open position
• Drainage pump 19 is deactivated, the water collecting in the interior of the trough 24 being able to flow out through the drain line in the form of a free-level drain. If the detector device 20 detects an increase in the basic Detects water level GW above a predetermined limit value, the control unit causes the closure flap 18 to be brought into the closed position, so that the entry of groundwater into the interior of the trough 24 is avoided, as shown in FIG. The trough interior 24 can be drained of any precipitation by activating the dewatering pump 19.
• FIGS. 3 and 4 show an alternative embodiment of the track system according to the invention, which differs from the example according to FIGS. 1 and 2 only in that two tracks running next to one another are now formed with their ballast bed 13 in a common trough 14a.
• a drain line 17 is formed in each of the two edge caps 16 and can be closed in the aforementioned manner with an associated closure flap 18.
• the bottom surface thereof is designed with a roof-shaped cross slope and a drainage pump 19 is arranged at the lowest point of each.
