Definitions

  • slab track means in particular a concrete track used in the railway superstructure.
  • the concrete track usually has an endlessly laid concrete slab, preferably a reinforced concrete slab.
  • Rail bases for supporting rails are usually integrated on these concrete slabs.
  • Railway superstructures designed as fixed carriageways have proven particularly useful for high-speed traffic.
  • the solid carriageway usually has a concrete base layer as the top base layer.
  • This concrete base layer lies on a hydraulically bound base layer which forms the lower base layer and is normally produced from concrete.
  • the subsoil under the lower base layer is made up of layers whose stiffness decreases from top to bottom. Despite this set-up, shifts, in particular vertical shifts or subsidence of the track body occur.
  • rail support structures are designed to be height and / or side adjustable.
  • the previously known and approved systems allow subsequent height corrections due to vertical displacements of the concrete carriageway slab of a maximum of 20 mm. In the area of embankment fillings with short lay times, settlement of the roadway substructure> 20 mm cannot be ruled out.
  • the Concrete slab due to driving operation especially under the influence of high-frequency vibrations, such as occur in high-speed traffic, cannot be excluded.
  • a method of the type mentioned is known from DE 196 31 430 A1.
  • the concrete base layer is raised by means of a lifting device which engages the rails and is supported by hydraulic rams with load distribution plates next to the road structure. Filling material is then introduced under the raised concrete base layer via feed lines between the concrete base layer and the hydraulically bound base layer arranged underneath.
  • This known method is distinguished by the disadvantage that the accuracy of the resetting largely depends on a low-deformation or non-deformation-supporting support of the lifting device next to the tracks. Resetting can only be carried out with reasonably satisfactory accuracy if the support is sufficiently firm.
  • a method of the type mentioned is also known from DE 196 23 305 A1.
  • track subsidence is to be compensated by injecting flowable and curable injection material into the affected floor area via boreholes and injection lances.
  • the settlements that have occurred should be compensated for or reversed by means of targeted and controlled press-in.
  • an increase is only achieved by soil injection, which means that only a relatively imprecise settlement of the settlements is achieved.
  • additional measures are often necessary to prevent the injection material from escaping to the side of the dam flanks.
  • This known method is relatively complex and, moreover, the routes concerned must also be blocked in the case of these compensation measures, which results in disadvantageous business interruptions.
  • the invention is based on the technical problem of specifying a method of the type mentioned at the beginning with which a functionally reliable and very precise compensation of vertical track body displacements or subsidence is achieved and when it is carried out, closures and operational disturbances of the route concerned can be reduced to a minimum.
  • This technical problem is solved by a method for compensating vertical track body displacements of a fixed carriageway, a plurality of manipulation chambers being introduced into a track body having a lower support layer and an upper support layer on at least one long side of the track body, at least one lifting tool being inserted into each manipulation chamber of the finished track body, all lifting tools (30) being controlled and / or regulated jointly from a control and / or regulating center (37), wherein the lifting tools are activated with the proviso that the upper base layer is raised relative to the lower base layer, so that an intermediate space is formed between the lower and upper base layers, and wherein the space is filled with a filling material.
  • the backfilling with the backfill material is expediently carried out with the proviso that the track body displacements are compensated for with millimeter precision.
  • the upper base layer is the concrete base layer of the solid carriageway.
  • the lower base layer is a hydraulically bound base layer, in particular made of concrete. The invention thus relates to a method for the subsequent precise compensation of track body displacements as a result of settlement or gradient changes on the track body which has already been completed.
  • the manipulation chambers are introduced by drilling and / or milling on the long side of the track body. It is advisable to first drill chambers into the long side of the track body, preferably introduced into the normally protruding hydraulically bound base layer of the slab track.
  • the manipulation chambers in the long side of the track body can then be produced in a simple manner from such a drilling chamber, in particular by drilling and / or milling.
  • the size of a manipulation chamber is designed so that it can hold a corresponding lifting tool, for example a capsule press or hydraulic press.
  • manipulation chambers are introduced with the stipulation on the long side of the track body that these manipulation chambers extend below the rail support points of the solid carriageway.
  • the manipulation chambers are located in the vertical direction below a rail base and thus there is a lifting tool attachment point in the vertical rail base axis and / or that the manipulation chambers are introduced from the long side of the track body at least up to the height of a rail base, so that there is a lifting tool attachment point in the area between two rail support points.
  • the manipulation chambers are introduced with the proviso on the long side of the track body that the manipulation chambers extend below a longitudinal reinforcement of the upper base layer designed as a concrete base layer.
  • manipulation chambers are arranged on each long side of the track body. It is within the scope of the invention to arrange a plurality of manipulation chambers at preselected intervals on each long side of the track body. As already described above, the manipulation chambers are introduced into the track body from the long side parallel to the upper base layer and parallel to the lower base layer.
  • the arrangement of manipulation chambers or lifting tools on both long sides of the track body makes it possible, among other things, to compensate for the inclination of the upper base layer or concrete base layer in the transverse direction. It is also within the scope of the invention, by specifying the spacing of the manipulation chambers or lifting tools on a long side of the track body, to bring about various lifting states in a functionally reliable and precise manner.
  • At least one filling element used in the manufacture of the track body is removed from the track body after completion of the track body, and the manipulation chambers are thereby formed.
  • This is an alternative according to the invention for the subsequent introduction of the manipulation chambers into the long side of the track body, for example by drilling and / or milling. It is within the scope of the invention to introduce at least one filling element in the lower base layer, preferably in the hydraulically bound base layer, before the upper base layer is applied or before the concrete base layer is concreted. After the concrete base layer has hardened or finished, the filling elements can then be removed, so that each manipulation chamber is formed for receiving at least one lifting tool.
  • precast concrete parts are provided as edge closure elements on at least one long side of the track body, which precast concrete parts are each equipped with manipulation chambers. It is therefore within the scope of the invention that manipulation chambers for lifting tools are already provided in a precast concrete part from the outset.
  • a precast concrete part attached as an edge closure element on the long side of the track body has at least one longitudinal reinforcement in the longitudinal direction of the track body. In this embodiment, the lifting forces exerted by means of a lifting tool are effectively introduced and distributed.
  • the precast concrete parts are expediently applied before the top base layer is applied, preferably the concrete base layer, attached to the lower base layer, preferably to the hydraulically bound base layer, and preferably screwed to the hydraulically bound base layer.
  • the attachment preferably screw connection, is expediently loosened before the lifting process.
  • the prefabricated concrete parts have reinforcement connections which protrude into the upper base layer, preferably concrete base layer. In this way, too, an effective and reliable transfer of the lifting forces into the upper base layer, preferably a concrete base layer, is achieved.
  • at least one injection hose is inserted on the underside of a prefabricated concrete part.
  • the joint gap can be closed by a quick-hardening mortar joint before the filling material is introduced.
  • a hydraulic press is used as the lifting tool.
  • the lifting process is initiated here by supplying a hydraulic medium.
  • a capsule press is used as a lifting tool.
  • Capsule press means in the context of the invention a press from two superposed floors, which preferably consist of sheet steel. The two floors are expediently along of a bead welded together.
  • a hydraulic medium preferably water, can preferably be introduced between the floors via a feed line.
  • the capsule press can be designed as a plate press or as a long belt press or tube press.
  • Capsule presses are particularly suitable as lifting tools for the invention. In particular when capsule presses are used, there is the possibility of minimizing the contact tensions between the lifting tool and the lower base layer, preferably a hydraulically bound base layer, by appropriate choice of the press contact area.
  • Release agents are preferably introduced between the upper base layer and the lower base layer in order to reduce the adhesive tension between the two base layers and thus to simplify the lifting process.
  • the release agent can be achieved, for example, by spraying on an emulsion, for example a wax emulsion or a bitumen emulsion. It is also within the scope of the invention to insert at least one separating film between the upper and lower base layers.
  • compressed air can also be used to separate the two layers. The compressed air is expediently pressed into the separating joint between the upper and lower base layers via filler neck which are provided anyway.
  • drilling channels in the horizontal parting line for example with the help of a hammer drill or core drill, whose drilling axis lies in the parting line between the upper and lower base layer. Hydraulic splitting tools or even explosive pumps can then be introduced into these drilling channels in order to support the lifting process or the detachment of the upper base layer.
  • the measures described can help to minimize the bending stress on the concrete base layer.
  • track body displacements or settlements are first precisely measured with the aid of suitable measuring devices, for example with the aid of measuring bridges, and the lifting operations according to the invention are then carried out as a function of the measured values obtained.
  • a precise lifting of the concrete base layer takes place in accordance with the measured course of a settlement trough by means of loop-controlled elevations.
  • the control loop-controlled elevations are carried out with the aid of the lifting tools with progressive measurement control, with online evaluation and simultaneous elevation control.
  • the lifting of the upper base layer according to the invention is carried out in several successive lifting phases carried out, during each lifting phase even the smallest stroke intervals can be realized, which are less than 1 mm, for example.
  • the manipulation chambers are introduced into the track body with the proviso that at least 50% of the volume, preferably at least 65% of the volume, very preferably at least 75% of the volume of the manipulation chamber is introduced in the lower base layer. It is within the scope of the invention that the manipulation chambers are introduced with the proviso from the long side of the track body that the upper base layer can be raised in a functionally reliable manner. According to a very preferred embodiment of the invention, at least 90% of the volume of the manipulation chamber is arranged in the lower base layer, preferably in the hydraulically bound base layer.
  • the space or uplift gap (parting line) created between the lower and upper base layer is filled with the filling material.
  • a filling mortar is expediently chosen as the filling material. It is within the scope of the invention to use a grouting mortar, such as that used for grouting machine foundations.
  • the backfill material is expediently desired depending on the respective boundary conditions, for example the lifting gap width Mortar setting time and required flow properties, adjusted.
  • the lifting tools are removed from the manipulation chambers again after filling the intermediate space.
  • the lifting tools used are expediently moved and reused together with an associated control and / or regulating unit.
  • the invention is based on the knowledge that with the method claimed in claim 1, a very precise compensation of track body displacements is functionally possible and millimeter-accurate height compensation can be achieved.
  • the track position corrections achieved according to the invention can nevertheless be achieved in a simple and inexpensive manner.
  • the invention is based in particular on the knowledge that it is sufficient to insert manipulation chambers only from the long side of the track body in order to achieve a very functionally reliable and effective track position correction with lifting tools arranged in these manipulation chambers. It is also of particular advantage in the method according to the invention that track closures are not absolutely necessary during the implementation of the method and that the route concerned can still be driven on, at least under certain conditions.
  • the lifting tools used can be fixed in a certain lifting condition and the route can be driven on despite the raised upper base layer, for example in slow travel.
  • relatively inexpensive measures namely only the introduction of manipulation chambers from the long side of the track body and subsequent insertion of lifting tools, a very precise correction of the track position can be carried out and nonetheless the driveability of the route remains guaranteed at least to a limited extent.
