Definitions

  • the invention relates to a method for installing a Rails and sleepers of existing track on support plates one fixed carriageway, the track initially with vertical and horizontal Adjustment means aligned vertically and horizontally and is supported on support means.
  • the invention further relates to a formwork and a conveying and installation device for feeding and installing one flowable, hardening stabilizing compound under the sleepers of a track on a solid track.
  • the track In the case of railroad tracks for railroad trains running at very high speed run, the track is on as a solid carriageway Base plates laid out of concrete or asphalt, with the sleepers of the track embedded in a filling concrete almost up to its upper edge and be firmly connected to the support plates. To one To achieve rapid construction progress, it is advisable to stop Prefabricate rails and sleepers and existing track grate the track with relatively large rail lengths on the Lay support plates and align them horizontally and vertically. Then the filling concrete between the sleepers and inserted the support plates, which is the final and permanent Connects between the track and the underground.
  • the object of the invention is to avoid these disadvantages and to design a method of the type explained in more detail above, that large rail lengths can be installed and a quicker Construction progress is achieved without position corrections during installation of the aligned track are required.
  • Thresholds after alignment by at least partially underfilling be stabilized with a hardening stabilizing compound, that then after the stabilizing compound has hardened sufficiently the rails on the sleepers loosened and only after the final and permanent attachment of the sleepers to the Carrier plates of the solid carriageway are fixed again with the sleepers get connected.
  • This configuration has the advantage that changes in length of the Rails due to changing temperature influences during installation the correct position of the aligned sleepers no longer can influence, since the rails after loosening the Rail fasteners on the sleepers in the longitudinal direction of the rail can move. Because to underfill the thresholds only small amounts of stabilizing compound are required the underfilling and stabilization of the sleepers is very quick. A very quickly hardening stabilizing compound is also useful used, which is sustainable after a short time and driving on the track just laid with transport and Installation equipment or a track laying and leveling machine allowed.
  • the adjusting means can also be used and / or the support means removed and at another Body can be reused.
  • pourable asphalt or Cement concrete used, which contains early high-strength binders.
  • the stabilizing compound can be applied to the whole of the sleepers Length can be arranged. As a rule, however, it is sufficient if the stabilizing mass under the sleepers is only of limited length is placed under the bearing points of the rails.
  • the thresholds are not subjected to bending when the track driven by a heavy track laying and leveling machine as is the case with single-track tunnel sections, for example the case is.
  • the stabilizing compound not only supports the thresholds from below, but also on their faces, so that the sleepers also against lateral displacement are secured.
  • the filling concrete that is introduced later must also fill the gap between the underside of the sleeper and the bottom of the support plates Fill in so that the thresholds are fully supported. Because this filling concrete may be introduced much later as the stabilizing compound, it is already hardened, before the filling concrete hardens and reaches its final shrinkage. It can then happen that individual thresholds in the finished condition only at their ends over the stabilizing compound Support on the support plates, but in their middle area lying hollow. To avoid this, a special suggestion goes the invention, under the ends of the sleepers in the area limited length in which the stabilizing mass is introduced will arrange a setting strip of compressible material its thickness is the shrinkage of the later under the threshold attached filling concrete corresponds.
  • This setting strip can from a glued or concreted on the underside of the threshold
  • Non-woven strips of plastic or textile material exist, which compresses under load, so that then the threshold along its entire length on the hardened and under certain circumstances, filler concrete that has become a little thinner.
  • the stabilizing mass is useful with a transport and Installation device supplied and installed on the laid Track moves along its alignment.
  • This promotion and Installation device consists of a train with light wagons, which storage containers for the stabilizing mass or its raw materials, an agitator or a mixer and the built-in devices for the masses and those of a small tractor, for example, a trolley moved in the longitudinal direction of the track become.
  • the tractor can also have an energy generator be equipped to drive the agitator or of the mixer and a pump or an injection unit for the To supply stabilizing mass with energy.
  • a lost formwork is provided, which in a Embodiment of a sack made of one for hardening Mass partially permeable material is formed.
  • the sack can from a coarse-mesh fabric, a fleece or a perforated Foil exist.
  • This sack is with an injection hose or an injection lance with which this can be connected Sack filled with the hardening mass from the mixer or agitator after being in the space between the Underside of the threshold to be stabilized and the Support plate was arranged.
  • the one filled in the sack with overpressure Stabilizing compound not only fills the sack, but also also partially emerges between the stitches of the fabric or the perforation of the film and also forms on the outside of the sack a layer consisting of the stabilizing mass, the combines well with the filling concrete to be introduced later, the is expediently produced on the same basis as the stabilizing compound, i.e. if the stabilizing mass is made of a cement concrete consists, the filling concrete is also a cement concrete. Will be against Asphalt concrete used as filling concrete is used as a stabilizing compound a bitumen-bound stabilizing compound is also useful.
  • the formwork is lost for installing a flowable, hardening mass under the Sleeper of a track on the supporting plates of a solid carriageway according to the invention from a formwork frame with side walls Made of expanded metal, which fits between the support plate and the threshold and over at least one side surface or a top surface of the Threshold protrudes.
  • Expanded metal walls can partially fill the stabilizing compound penetrate through the walls and get on well with the Interlock and connect the filling compound to be filled in later, so that Stabilizing compound and filling concrete in the final, hardened state form a monolithic body in which the thresholds of the track are firmly anchored.
  • the formwork frame can have two side walls and at least one Have front wall.
  • One end wall fills the distance at least approximately between the threshold and the support plate.
  • this first end wall expediently has a curved one Tab that lies under the threshold and thereby the Formwork frame stabilized at the head end of the threshold.
  • the sidewalls and, if necessary, a second end wall, which the formwork frame closes at the rear and also expediently made of expanded metal are higher than those below the threshold End wall of the formwork frame.
  • the to the top of the side walls filled stabilizing compound not only underfills the threshold at their ends, but also trims them at theirs End faces, so that these sleepers against side shift are secured.

  • FIG. 1 The alignment and support is shown in FIG. 1 in the area PH2. It is done either with the help of a track 11 moving track straightener, or as shown in Fig. 3, manually with individual straightening and supporting devices, such as Vertical spindles 19, the vertical holes 20 in the sleepers 15 penetrate and rest on the bottom 18 of the support plates 15 and with horizontal adjusting means 21 with which the Thresholds can be set in the horizontal direction.
  • This horizontal adjustment means 21 are also screw spindles, which engage in threaded sleeves 22, which in the head surfaces 23rd the thresholds are arranged. Support with the other end the horizontal screw spindles 21 on the side cheeks 14 the support plates 12 from.
  • This proppant 27 can be the vertical spindles 19 with which the Thresholds 15 have already been aligned in their altitude.
  • the support means however, special support spindles between the sleepers can be arranged directly under the rails. Instead of the support spindles can also support frames made of concrete, hydraulic rams or other height-adjustable supports are used become.
  • This construction phase is shown in FIG. 1 in the area PH3.
  • the lost formwork is the one shown in FIGS. 1 and 2 Embodiment bags 24 from a coarse-mesh Fabric, a fleece or a perforated film. you will be from a transport and installation device 25 with a hardening stabilizing mass 26 filled, as in the area PH4 is shown in Fig. 1.
  • this stabilizing compound 26 is a mastic asphalt or a flowable cement concrete, which is preferably a early high strength cement is added as a binder, so that the Stabilizing compound 26 soon after it is filled into the sacks 24 hardened.
  • the stabilizing mass 26 is using an injection lance or an injection hose 28 with excess pressure in the bag formwork 24 filled. This allows the air from the Bags 24 escape and after the bags are completely filled 14 can some stabilizing mass through the mesh or perforation of the sack to the outside and harden there. At the Subsequent pouring of the filling concrete connects it then with the outward stabilizing material and it gives a good interlock between the two materials.
  • Fig. 1 shown in phase PH4.
  • the stabilizing compound 26 has hardened to the extent that it Load of the track and the transport and installation equipment traveling over it can be transferred to the support plates 12 the fasteners 17 of the rails 16 solved so far that the rails 16 in their longitudinal direction on the concrete sleepers 15 can move and no longer transmit longitudinal forces, if they lengthen due to the effects of temperature or shorten it.
  • the vertical spindles can also be used 19, the horizontal adjustment means 21 or other support means be removed. This process section is in the area in FIG. 1 PH5 shown.
  • Fig.1 Installation device 25 consists of a train light wagons 29 and 30 by a small tractor 31, for example a draisine in the installation direction 32 over the just laid track 11 are pulled.
