Definitions

  • the present invention relates to a method for producing a slab track for high-speed rail transport from prefabricated precast concrete, which is placed on a support layer and a gap between the precast concrete part and the support layer for fixing the position of the precast concrete part is poured with a solidifying filling material or in-situ concrete or a Combination of precast concrete and in-situ concrete is produced on the base course and a corresponding track of a slab track.
  • the base course is made of an existing ballast bed.
  • the construction of driveways for high-speed rail transport is usually carried out either on a ballast track or with a slab track, which is made for example of a variety of precast concrete parts.
  • a disadvantage of gravel superstructure is the high maintenance intensity, while in the slab track a longer construction time and higher costs are to be accepted. If a high-speed line is being built, it will either be built on a new line or replace a conventional rail line. In the latter case, the existing ballast bed is completely degraded and built a hydraulically bonded support layer on which the precast concrete or an in-situ concrete layer or a combination thereof are laid or built. This removal of the old line and construction of the new line essentially creates the long construction time and high costs.
  • the US 3,656,690 describes a track for a high speed train using an existing ballast bed to build the track.
  • the old rails and sleepers are removed and the existing ballast bed is dismantled.
  • the gravel is cleaned and finally rebuilt in the form of a trough.
  • the flanks of the trough are solidified and filled the space between the flanks.
  • concrete slabs are built for the new infrastructure. Due to the dismantling of the old ballast bed, the construction time is correspondingly long.
  • Object of the present invention is to provide a method for producing a slab track and a corresponding track, which avoids the disadvantages mentioned above and in particular to enable fast and relatively low cost high-speed rail transport.
  • prefabricated precast concrete elements are set up on a base course and an intermediate space between the finished parts and the base layer for fixing the position of the finished parts is filled with a solidifying filling compound.
  • the slab track can also be built with in-situ concrete, which is poured on the base course.
  • the base course is made from an existing ballast bed.
  • the gravel used for the old track to be dismantled is thus used for the construction of a base course for the new slab track.
  • the ballast is solidified by a binder between thresholds of a still old track is introduced into the ballast bed and after setting of the binder, the tracks sleepers and superfluous ballast be removed.
  • the high speed line can thereby be prepared while the rail traffic is still being performed on the old track.
  • the downtime between rail traffic on the old tracks and rail traffic on the new tracks can thus be kept very short. If, after setting the binder, the tracks, sleepers and superfluous ballast are removed, the basis for the construction of precast concrete slabs on the base course is created. This measure also contributes to a very short shutdown time.
  • ballast bed would not have been suitable to meet the high demands for high-speed rail transport, it is now possible through the processing of the existing ballast bed to significantly improve the properties and to use the former substructure for the new base course. It is thereby achieved the advantage that the conversion of a conventional track system on a track system for high-speed rail transport is relatively quickly and inexpensively feasible.
  • the support layer produced thereby very stable and especially by the shocks and stresses that arise during operation of high-speed rail transport, very resistant. It is thus a durable and reliable substrate for the installation of precast concrete elements, which are usually used as plates, or the in-situ concrete layer created.
  • the binder If the binder is pressed under pressure into the cavities of the ballast bed, the result is a possibly full ballast bed enforcing load-bearing area of the ballast bed.
  • the cavities which are present between the individual ballast stones, are used to position the binder can.
  • the result is a connection between the binder and the ballast, creating a very reliable support layer is created.
  • injection lances are advantageous, which are shaken into the ballast bed and through which the binder can be pressed into the cavities of the ballast bed.
  • the enforcement of the ballast bed with binder can thereby be very uniform and targeted.
  • binder is introduced at least in one direction at a distance from each other, so that hydraulically bound areas and unfilled intermediate areas arise in the ballast bed, so it can be addressed to the individual required carrying capacity of the support layer.
  • the unfilled intermediate areas are greater than at a higher required carrying capacity of the base course.
  • the filling compound poured between the base layer and the precast concrete element is advantageously provided that at least the unfilled areas are sealed on the surface.
  • a relatively thin layer of cement mortar is applied to the unfilled and optionally additionally to the bonded areas. The filling material is thereby prevented from flowing into the cavities of the ballast bed and thus not sufficiently support the precast concrete slab.
  • the surface of the ballast bed is milled and the resulting milled material is mixed with the binder. Subsequently, the mixture is applied to the surface of the remaining ballast bed as a support layer. After setting this mixture, the precast concrete slab or the in-situ concrete layer is built on the newly created surface.
  • a support layer is also created very quickly.
  • this is in contrast to the particularly advantageous embodiment of the pressing of the binder between the thresholds of the old track required that the old track has been dismantled before the top layer of the ballast bed is milled and rebuilt.
  • the mixing of the binder with the resulting milled material can be carried out by applying the binder to the surface of the ballast bed prior to milling.
  • the milling of the binder and the ballast bed automatically mixes binder and ballast. This mixture can then be reapplied and cured on the remaining ballast bed.
  • the binder is mixed after milling with the milled material.
  • the milled-out material is brought, for example, into a mixing chamber in which the binder and the material are mixed with one another and then reapplied to the permanent layer of ballast. After the binding of the binder, a strong and stable base course has been created here.
  • Another alternative to producing a base layer using the old ballast bed and a binder is that the binder is laid over the ballast bed in the manner of a clamp, the binder penetrating into the surface of the ballast bed, closing it laterally. The ballast bed is thereby prevented from breaking up laterally.
  • the binder, which partially penetrates into the ballast bed ensures thereby a toothing of the bracket with the ballast bed and thus for a stable base course for a trouble-free high-speed rail.
  • the hydraulic binder combines with the gravel of the existing ballast bed and thus forms the load-bearing layer on which the precast concrete elements or the in-situ concrete layer can be built.
  • the precast concrete elements are placed on a support layer.
  • a space between the precast concrete elements and the base layer is poured out to fix the position of the precast concrete parts with a solidifying filler.
  • the precast concrete parts can also be an in-situ concrete layer or in-situ concrete in combination with precast elements for the construction of a slab track.
  • the base course is made of an existing ballast bed.
  • the ballast in the ballast bed is at least partially solidified by a binder between sleepers of a still old track is inserted into the ballast bed.
  • ballast is connected to a hydraulically setting or bituminous or plastic-based binder, a particularly firm and load-bearing supporting layer is obtained.
  • the binder is pressed under pressure into the cavities of the ballast bed. This allows a deep penetration of the ballast with the binder. A high strength of the support layer is thus achieved.
  • the binder which is supplied under pressure to the ballast bed, on the one hand fills the voids of the ballast bed and optionally compresses loose ballast in addition to the connection with the binder.
  • the binder is not introduced over the entire ballast bed, but at least in one direction at a distance, so hydraulically bound areas and unfilled intermediate areas are arranged in the ballast bed.
  • the production of such a support layer is thereby made possible very quickly.
  • a usually sufficient strength and bearing capacity of the support layer is achieved, even if intermediate areas remain unfilled.
  • a sealant may for example be cement mortar, which is applied over the unfilled areas and possibly also the filled areas and thus creates a uniform dense surface for the filling compound.
  • ballast bed is milled in the ballast bed additionally or alternatively to the injection of binder under pressure and the milled material is mixed with the binder, a composite material is obtained which forms the support layer.
  • This composite material is applied to the surface of the remaining ballast bed and is suitable for constructing the precast concrete or in-situ concrete layer on this newly created surface.
  • the binder is liquid and placed like a clip over the ballast bed, a particularly good cohesion of the ballast is obtained from the ballast bed. In some applications, this type of production will be sufficient for the base layer of an existing ballast bed and binder. It is particularly advantageous if the binder penetrates about 5 to 20 cm into the surface and the side surface of the ballast bed in order to effect a clawing of the binder with the ballast layer. It is thus obtained a particularly strong cohesion and a high load capacity of the old ballast bed with the additionally arranged binder. The operation of high-speed trains on the old gravel bed thus processed is made possible.
  • the present invention also has the advantage that, in particular in the case of the arrangement of unfilled and filled areas of the ballast bed, drainage through the unfilled areas can take place. Especially during the expansion phase, while maintaining conventional driving, this is particularly advantageous.
  • the following embodiments illustrate the invention with reference to a slab track with precast concrete elements.
  • the invention is not limited thereto, but can also be used when the slab track is constructed of in-situ concrete or in combination with in-situ concrete and precast concrete elements.

  • the ballast bed 2 is prepared for conversion for a support layer of a slab track.
  • a plurality of columns 4 are incorporated in the ballast bed 2, which consist of ballast and binder.
  • the columns 4 are arranged between sleepers 5 and can thus be introduced into the ballast bed 2, without the driving operation must be set permanently. After the columns 4, for example, under pressure and injection lances were introduced into the ballast bed 2, the driving operation can be resumed. Through this only brief interruption, a particularly cost-effective construction or cost-effective preparation of the creation of a slab track is possible.
  • the columns 4 are arranged in rows, which are each located between two sleepers 5.
  • the unfilled ballast bed 2 is still sufficient in this case to provide drainage. Between the columns 4 is still the unfilled ballast 2.
  • FIG. 2 shows a cross section through a ballast bed 2 according to FIG. 1 , It can be seen that the columns 4 are arranged on the substrate 1 and are spaced from the surface of the ballast bed 2. In addition, they have distances to each other, which corresponds to the width of the threshold 5 substantially. This makes it possible that the columns 4 can be introduced from the top of the ballast bed 2 ago between the sleepers 5 in the ballast bed 2.
  • the columns 4 are formed with binder and the ballast from the ballast bed 2.
  • the tops of the columns 4 are approximately level so that they later serve as a uniform support layer for a precast concrete slab.
  • FIG. 3 is a perspective view of a support layer shown, which according to the representations of FIGS. 1 and 2 was prepared.
  • the old track grid 3 with the sleepers 5 and the rails 6 has been in the meantime reduced.
  • Excess ballast from the ballast bed 2 has been eliminated, so that the surfaces of the columns 4 lie substantially in one plane.
  • the pillars 4 form the pillars for a slab track at a later time.
  • the excess ballast which was located above the surface of the columns 4 in the old ballast bed 2, was cleared aside and can later be used, for example, to fill the slope.
  • FIG. 4 shows a cross section through the structure according to the invention of a slab track.
  • the track 6 is mounted on a precast concrete part 7, which is designed plate-shaped.

  • the surface of the supporting layer is provided with a sealant 9 before the precast concrete part 7 is placed on the support layer.
  • the sealant 9 which is e.g. a cement mortar, causes the filling material 8 can not penetrate into the cavities of the ballast bed 2 and does not completely fill the cavity between the precast concrete part and the support layer.
  • pipes 10 are provided, which pass the water through the precast concrete part 7, the filling compound 8 and the sealant 9. In the unfilled area of the ballast bed 2, the water can then seep or laterally led out of the ballast bed 2.
  • FIG. 5 shows the milling of a binder 15, such as mortar or concrete, in the ballast bed 2.
  • the binder layer 15 is applied, which is milled together with a part of the ballast bed 2 by a mill.
  • the milled material of the ballast bed 2 and the binder 15 is mixed and then applied as a support layer 16 on the remaining part of the ballast bed.
  • a very durable layer for the construction of a slab for high-speed rail transport is created.
  • FIG. 6 shows a cross section through a support layer 16 according to FIG. 5 on which a precast concrete part 7 is arranged.
  • a filling compound 8 is arranged, which fixes the position of the precast concrete part 7.

  • the binder 15 surrounds the ballast bed 2 both on its upper side and on its flanks.
  • a staple-like embrace of the ballast bed 2 with the binder layer 15 is achieved.
  • the load capacity and the cohesion of the ballast bed 2 is thereby increased and causes a very good load capacity of the support layer, which does not change even with shocks, for example in a crossing - a high-speed train in their position.
  • the maintenance effort Such a route is thereby kept particularly low.
  • the binder 15 can be easily penetrated into the cavities of the ballast bed 2.
