Definitions

• the present invention relates to a method and a device for correcting the position of the slab construction made of precast concrete slabs, in particular a solid carriageway for high-speed means of transport, the precast slabs being infused with a hardenable casting compound and being carried on a base layer of the substrate.
• Known plate constructions made of precast concrete slabs are used, among other things, as a solid carriageway for high-speed means of transport.
• the high-speed means of transport are guided by rails.
• the position of the rails is usually corrected using known rail fastening systems and by installing intermediate layers of different thicknesses below the rails. In this way, ice layer errors of around 30 mm can be compensated for.
• larger corrections such as are required, for example, when subsoil has been set, can no longer be corrected with such corrective measures, since they often require significantly larger corrective movements.
• the object of the present invention is therefore to enable a position correction of a plate construction made of precast concrete slabs, which also enables larger correction heights.
• the position of a plate construction made of precast concrete slabs, in particular a fixed roadway for high-speed means of transport is corrected.
• the plate construction advantageously has two interconnected prefabricated panels, the prefabricated panels being cast under a substructure with a hardenable casting compound and being carried on a base layer of the substrate.
• the prefabricated panel is completely or partially detached from the casting compound and / or the base layer, then refined and then re-poured with a casting compound. Large height corrections can be carried out with this method. The release can take place either chemically or mechanically. The most advantageous method depends in particular on the ambient conditions and the material of the base.
• the substructure in particular the casting compound and / or the base layer is cut in the longitudinal and / or transverse direction of the prefabricated panel, a very simple way of releasing the prefabricated panel is used, the choice of whether the substructure should be cut in the longitudinal or transverse direction, depends on the type of lowering of the plate, the tools available and the ambient conditions.
• the dividing line has a length that is not equal to the length of a prefabricated panel, in particular does not begin or end at the joint of two prefabricated panels, a possible weak point on the panel joint is avoided.
• filling of the new pouring is made considerably easier. Filling the mass substantially without air pockets is made possible.
• the prefabricated plate is finely aligned with mechanical or hydraulic lifting means, for example spindles, arranged in the prefabricated plate, then the alignment of the prefabricated plate is made possible in a simple manner with means which are often still present in the prefabricated plate from the first fine-leveling.
• the spindles are brought out of the area of the severing cut prior to severing and are brought into their supporting position only after severing.
• the precast slab is infused with a bitumen-cement mortar, plastic or cement mortar, which hardens particularly quickly.
• a device has a separating device for releasing, in particular for severing a substructure, in particular the casting compound, which is arranged under a prefabricated panel of a fixed carriageway for rail-guided high-speed means of transport.
• the fixed carriageway often consists of at least a first and a second prefabricated panel connected to one another.
• the separating device is arranged on the prefabricated panel to be detached or on a downstream panel, preferably on the rails.
• Another device has a separating device for detaching at least a part of a prefabricated slab of a solid carriageway for rail-guided high-speed means of transport from its substructure.
• the separating device is arranged on a guide which is independent of the prefabricated panel to be detached, in particular a siding.
• the fixed carriageways are usually laid on two tracks, so that the separating device can be guided on the siding to loosen the necessary carriageway.
• the separating device within the assembly exerts a stroke in the longitudinal direction of the prefabricated plate, then with a fixed arrangement of an abutment of the separating device, a relatively long distance can be covered, on which the separating cut can be carried out.
• the separating device and / or the assembly is advantageously guided on the rails. This enables a precisely guided cut. If the assembly is firmly arranged on the rails, in particular clamped, a quick change to extend the separating cut is possible.
• FIG. 1 shows a top view of a precast concrete slab
• FIG. 2 shows a cross section through the construction of a bearing for a precast concrete slab
• FIG. 3 shows a section through the casting compound
• FIG. 4 a lifting of the prefabricated panel
• FIG. 5 shows a pouring out of the gap between the prefabricated panel and the base course
• Figure 6 shows an embodiment of a wire saw.
• the prefabricated panel 1 shows a plan view of a prefabricated panel 1.
• the prefabricated panel 1 has a plurality of individual bumps on which rails 2 are fastened.
• the rail fastenings which can be implemented in different known forms, allow a certain adjustment of the rail in the vertical and horizontal direction. If this adjustment option is not sufficient, for example due to subsidence of the subsurface, it is necessary to adjust the height of the prefabricated panel 1 itself.
• spindles 7 are arranged at six points in the present exemplary embodiment, which serve to adjust the plate 1.
• the spindles 7, which at the ends of the plate 1 and here also in the middle of the plate 1 are provided, allow a more or less strong unscrewing of the spindles 7 a fine adjustment of the plate 1.
• These spindles 7, which are usually already used when laying the plate 1, are given a second task by the present invention, namely by correcting the Allow already installed plate 1.
• the spindles 7 are arranged in recesses in the plate 1.
• the prefabricated panel 1 is arranged on a base layer 5 with the interposition of a lower casting 4.
• the base layer can be, for example, hydraulically bound or it can also be an asphalt or other suitable base layer.
• the bottom casting 4 firmly connects the prefabricated panel 1 to the base layer 5.
• a spindle 7, which was used to align the prefabricated panel 1 during the first laying, is shown in the retracted state since it does not have a supporting function in the prefabricated panel 1. It is arranged in a recess in the lower casting 4, so that it can still be operated.
• the under-pouring layer 4 is cut according to FIG. 3.
• the finished part plate 1 after the bottom casting layer 4 has been cut through, is movable in the vertical direction as part of its integration into the plate construction. It is particularly advantageous if the cut is made in the under-pouring layer 4 directly at the point of separation from the precast panel 1.
• a reliable connection of the new pouring compound 4, which is later re-filled, is significantly improved with the precast plate 1.
• the old connecting layer of the under-pouring layer 4 with the prefabricated panel 1 is hereby dissolved as a supporting function and connected to the new layer. It can also be advantageous to make the separating cut at the connection point between the base layer 5 and the base casting 4. This also renews any loose connection.
• connection point The separation at or near the connection point between the prefabricated panel 1 and the casting 4 is easier to carry out, however, since the thickness is known the precast panel 1 this point is easy to detect by means of a control system. Since the thickness of the base casting 4 can be different, this connection point is easier to determine than the connection point to the hydraulically bound base layer 5.
• the prefabricated panel 1 is to be lowered, a cuboid piece of the lower casting 4 is cut out and then the prefabricated panel 1 is lowered into the resulting cavity.
• FIG. 4 shows the lifting of the prefabricated panel 1.
• the arrangement of the separating device on the precast plate 1 is outlined in FIG.
• the separating device which is a wire saw, an oxygen lance or similar. can be arranged on a movable carriage 21.
• the carriage 21 is pulled by means of a cable winch over the point at which the precast plate 1 is to be separated.
• the winch or the rope is attached to a fixed point as an abutment.
• the fixed point is preferably arranged on the adjacent prefabricated panel 1.
• the track 2 laid on the precast plate 1 can serve as a guide for the slide 21.
• the track 2 can also be used for fastening the abutment.
• the abutment is preferably clamped on the track 2 and can be moved to continue the separating cut after the maximum displacement of the slide 21 has been used up.
• the gap is cleaned, for example with a high-pressure cleaner, before filling.
• the gap can also be made in the base layer if the new casting material is designed to make a good connection with this material.
• the present invention can also be used for the replacement of complete precast concrete slabs.
• the panels are completely detached from a composite construction and an exchange panel is then reinserted.
