Definitions

  • the invention relates to a method for partially or completely foaming the voids in the ballast of a ballast bed, under which a planum is arranged, with a reactive plastic in which the reactive components are metered to at least one high-pressure mixing head and mixed there and discharged from the high-pressure mixing head liquid Reactive mixture is applied free-flowing on the surface of the ballast tower. Furthermore, the invention relates to a device for foaming the cavities in the ballast of a ballast bed, under which a planum is arranged, with a reactive plastic.
  • the traditional railway path consists essentially of the so-called planum applied ballast bed, in which the sleepers, which may consist of wood, concrete or steel, are embedded and on which the rails are attached.
  • DD 86201 has set itself the task of causing a substantial increase in the lateral displacement resistances and proposes to strengthen the threshold compartments by metering hardened plastic resins in the spraying or pouring process, whereby the plastic is atomised or cast as a film , That is, this patent describes measures to improve the ballast bed stability against horizontal track forces, namely by gluing the ballast stones in the upper part of the ballast stand together.
  • the stability against horizontal track forces is to be improved by gluing the ballast scaffold located laterally outside the two rails "at most" to about the threshold lower edge at the points of contact.
  • the stability against vertical track forces is to be improved by partially or completely filling the cavities of the ballast structure in the area under the sleeper bearing, so that the stones are adhesively bonded to the surface.
  • the gluing at the points of contact of the ballast stones in the upper area of the ballast tower should be done by "raining or trickling".
  • the surface bonding of the ballast stones to the substrate should be done by "injecting" the binder.
  • EP 1 619 305 refers to foam lances to inject the reactive plastic into the ballast structure.
  • the reactive plastic is polyurethane.
  • a planum is the separating layer between the superstructure and the substructure of a track construction.
  • the superstructure consists of the track, the sleepers on which the track is fixed, and the ballast bed in which the sleepers are located.
  • ballast bed is a heap of gravel to understand.
  • the ballast bed is a ballast bed for track systems, i. that in the upper part of the ballast bed sleepers are arranged, on which in turn rails are attached.
  • the ballast is usually compacted in layers.
  • gravel of different grain sizes can be used. It is common, for example, the use of gravel with a grain size of 22.4 to 63 mm. If necessary, this can also be mixed with gravel with a particle size of 16 to 22 mm.
  • the gravel content of the ballast bed is to be understood in contrast to the cavities.
  • FIGS. 1 to 6 show an example of the solution for the described task. They illustrate a method for partially foaming the voids in the ballast of ballast beds with a reactive plastic, for example with polyurethane, wherein in the upper part of the ballast bed sleepers are arranged, on which in turn rails are attached.
  • a reactive plastic for example with polyurethane
  • the reactive components are metered to at least one high-pressure mixing head and mixed there and then applied the liquid reactive mixture through the high-pressure mixing head itself above the ballast bed on the ballast and allowed to flow through the ballast bed through to the subgrade under the ballast bed. Thereafter, the reactive mixture will foam and thereby rise.
  • the so-called start time for the reactive mixture is adjusted so that the foaming process essentially begins only when the reactive mixture has reached the level.
  • a high-pressure mixing head the components are sprayed via nozzles, which convert the pressure energy into flow energy, into a small mixing chamber in which they mix with each other due to their high kinetic energy.
  • the pressure of the components entering the nozzles is at an absolute pressure of more than 25 bar, preferably in a range between 30 and 300 bar.
  • the mixing chamber is cleaned mechanically after firing by means of a plunger.
  • mixing heads which are blown out with air.
  • the main advantage of the high-pressure mixing head is the fact that these mixing heads can be cleaned much better and without the use of solvents after each shot.
  • high-pressure mixing heads are one-, two- or three-stage mixing heads in question, all of which are self-cleaning. That is, in these types of mixing heads, the complete mixing and discharge system is mechanically cleaned by slide from reactive mixture, so that then no more complicated rinsing and cleaning operations are required.
  • the decision as to whether a one-, two- or three-slide mixing head is used depends on the degree of difficulty of the mixing task for the reactive mixture.
  • a squeegee mixing head is quite sufficient, for example the so-called “groove mixing head” well-known in the PUR (polyurethane) industry.
  • a two-slide mixing head e.g. the MT mixing head of the company Hennecke, required.
  • a three-slide mixing head e.g. the MX mixing head of the company Hennecke.
  • this high-quality mixing system there is a control valve for the mixing chamber area, a throttle slide for the throttle zone and a separate slide for the outlet area.
  • a high-pressure mixing head which has a separate outlet channel, and through which the reactive mixture can be discharged laminar and free of spatter.
  • Also essential for this new process is the process optimized set start time for the reactive mixture. For only in this way is it possible to apply the reactive mixture above the ballast bed to the ballast structure, to allow it to flow through the ballast bed to the ground under the ballast bed and then lather it and thereby allow it to rise.
  • the start time is preferably set via the amount of activator in the recipe.
  • a high proportion in the formulation causes a short start time, while a low proportion causes a long start time.
  • the process is particularly flexible when the activator is dosed individually, as it can react directly and flexibly to the other conditions (ballast bed height, grain size, temperature).
  • the usual activators in polyurethane chemistry generally known amine-containing or organometallic catalysts can be used as an activator.
  • low-emission or emission-free catalysts should be used which are not elouted by precipitation water.
  • catalysts which react with the precipitation water to give ecologically harmless products are particularly preferred.
  • the method is surprisingly simple in that, without lances immersed in the heap, it is possible to foam out defined areas in the heap which is limited only by free flow.
  • the starting time for the reactive mixture should be 3 to 30 seconds, preferably 4 to 20 seconds, particularly preferably 5 to 15 seconds.
  • the start time to be set is dependent on the mixture viscosity of the raw material system, the grain size and packing density of the ballast bed, but above all on the ballast bed height H , which may be 20 to 40 cm, but in curves may also be 70 to 80 cm.
  • the Schott temperature has an influence on the flow behavior and thus on the start time to be set.
  • the appropriate start time can easily be determined empirically by considering the resulting foam cone as a function of the selected start time.
  • Another variant consists in providing one of the main components with a basic activation or basic catalysis and mixing in only further catalyst or activator if necessary.
  • the activator in the desired amount in the Nach Schollmengenstrom one of the main components, preferably the polyol component, is metered and mixed.
  • the reactive plastic In a further process optimization, it is also possible to vary the size of the contact surface F between the planum and the reactive plastic and the rise height Z S of foaming within the ballast bed the reactive plastic, essentially by the mass M applied reactive mixture, consistency of the chemical or physical parameters, such as mixture viscosity, propellant and thus foam density provided.
  • the applied mass M results from the product of mass flow ⁇ per unit time and the metering time t D.
  • the mixture discharge at the outlet from the high pressure mixing head is as laminar as possible, so as to ensure a substantially aligned in the vertical direction, undisturbed flow through the reactive mixture through the ballast bed; because with a turbulent, spurting mixture discharge, the reactive mixture in the ballast would almost "run".
  • the mixing head type plays an important role, but also the speed at which the reactive mixture leaves the mixing head.
  • the permissible speeds for a laminar Gemischaustrag are very much dependent on the mixture viscosity. So with mixture viscosities over 1000 mPas are quite Exit speeds up to 10 m / s possible. For mixed viscosities below 500 mPas, however, only approx. 1 to 3 m / s are permissible.
  • the exit velocity from the outlet from the high pressure mixing head is adjusted so that a laminar flow of the reactive mixture is established at the outlet from the mixing head outlet.
  • An additional influencing factor for laminar mixture discharge is the distance d between the mixing head outlet and the ballast stand.
  • distances up to 50 cm are quite possible.
  • the distance should be only 0.5 to 10 cm.
  • the ballast stones are tempered in the ballast bed. This means that in winter at minus temperatures, the gravel stones are heated and cooled in the summer in extreme heat.
  • the optimum operating temperatures of the ballast stones are about 20 to 50 ° C, preferably at 25 to 40 ° C, more preferably at about 30 to 35 ° C.
  • ballast stones in the so-called load transfer cone below the thresholds, over which the track forces occurring by the driving operation in the planum, in their position, so that they no longer twisting and shifting, whereby a significant increase in the life of ballast beds is achieved.
  • each support of the railroad track on the threshold each 2 to 8 injection points not more than 40 cm away from this support of the railroad track on the threshold.
  • these injection points are located in each case half on both sides of the threshold.
  • the reaction mixture is injected exclusively in this area. It is better, however, if additional injection points are arranged over the entire threshold width, so as to minimize the total lateral resistance and the setting of the track due to the load. However, more than 24 injection points per threshold no longer make sense, since in this case the amount to be injected per injection point is so low that form no more suitable foam chimneys. Consequently, the reactive mixture should be injected per threshold at 4 to a maximum of 24 points and preferably at 8 to a maximum of 20 points.
  • this one mixing head a so-called “antler” (see FIGS. 3 and 4 ). It is a simple power split on several outlet pipes. However, the flow rate should be at least 0.5 m / s, so that the antler does not clog too fast. However, this "antler” is not self-cleaning and therefore needs to be replaced from time to time.
  • the solution which is certainly more expensive than the investment costs, consists of using two dosing units and two mixing heads, which discharge the reactive mixture simultaneously on both sides of the threshold (see FIGS. 5 and 6 ). Otherwise, however, this method has the advantage of unrestricted applicability. This means that this variant can also be used for highly reactive raw material systems.
  • the mixture is introduced along the threshold, ie substantially parallel to the longitudinal axis of the threshold (ie in the direction of the Y-axis in Fig. 8 ), and preferably substantially in a passage which is interrupted only briefly during the crossing of the rails. That is, interrupted in these phases, only the Gemischaustrag, but not the further transport of the mixing heads.
  • the mixture entry along the threshold, ie substantially parallel to the longitudinal axis of the threshold (ie in the direction of the Y-axis in Fig. 8 ).
  • the reaction mixture is preferably injected at regular intervals at at least 6 points per threshold side.
  • the reaction mixture is at each of the at least 6 positions along the Y-axis in Fig. 8 each entered first at a Y-position on both sides of the threshold, before the next position (on the Y-axis) is approached along the threshold.
  • the mixture entry along the threshold is a function of the distance (ie of Y in Fig. 8 ), so that the rise height Z S of the rising foam in the ballast tower a function of the distance (ie of Y in Fig. 8 ) is (see also FIGS. 7 and 8th ).
  • the adaptation of the metering time from step to step is the more sensible method.
  • ballast bed drainage consists in the center line of the ballast bed seen in the direction of travel, quasi form a watershed, ie that the maximum rise height Z Smax is at the threshold center and the troughs extend from the ballast bed center to the ballast bed sides .
  • the ballast bed ends at the time of foam entry at the lower end of the thresholds and can optionally be further filled then.
  • the reaction mixture can be entered immediately next to the threshold.
  • a self-cleaning high-pressure mixing head As a mixing head, a self-cleaning high-pressure mixing head, whether a one-, two- or three-slider mixing head, has the preference in any case. Although there are also air cleaned high-pressure mixing heads, the use of which would significantly reduce the benefits of the described method, especially in ecological terms.
  • the metering units for the two reaction components polyol and isocyanate must be suitable for applying absolute pressures of at least 25 bar, preferably from 30 to 300 bar.
  • the dosing unit for the activator is important in order to be able to react flexibly to the other conditions (ballast bed height, grain size, temperature).
  • the most flexible solution is to dose the activator individually into the mixing head.
  • An alternative is the seeding of the polyol stream with the activator, which is then injected via the polyol nozzle into the mixing chamber. In this case, however, the activator may only be injected during the firing time, as otherwise it accumulates undefined in the polyol container. Also conceivable is the seeding of the isocyanate stream with the activator.
  • the metering unit for the activator is usually a suitable metering pump.
  • a suitable metering pump other types of dosage are also conceivable.
  • the activator can also be metered into one of the reaction components by means of pre-pressure and a flexibly controllable, fast-switching valve.
  • the ballast bed is first produced from washed, dried and compacted ballast.
  • Either the dry ballast bed is then immediately foamed directly after the characterizing features of claim 1 according to the invention or it is temporarily covered to protect against rainfall in a suitable manner to keep it dry until the time of foaming.
  • simple, mobile wagons which consist in the simplest case only of a scaffold with cover and wheels, is conceivable.
  • the advantage of this variant is that the gravel can of course be dried much easier if it is not yet in the track bed. Otherwise, it is only possible with very great energetic effort to dry the ballast to Planum. It would be ideal if the foaming machine is arranged directly behind the machine, which generates the ballast bed, so that the dry ballast bed is always filled directly.
  • the handling devices are also associated with a sensor to position the mixing head. In this way it is possible to run the foaming process completely automatically.
  • the effluent from the high pressure mixing head is oriented substantially vertically (i.e., at a maximum angle of inclination to the vertical of 10 °) so that the reactive mixture is free to flow in the vertical direction as laminarly possible (i.e., avoiding splashing).
  • the spout from the high pressure mixing head is oriented substantially perpendicular to the direction of travel of the rail vehicle (i.e., at a maximum angle of inclination to the direction of travel of 10 ° to the direction of travel).
  • the rail vehicle has wheels, wherein the outlet from the high-pressure mixing head in the discharge direction from the high-pressure mixing head is at most 30 cm in front of the rearmost in the discharge direction of the wheels and particularly preferably in the discharge rearmost extent of the wheels even towers. Most preferably, the outlet from the high-pressure mixing head projects beyond the rearmost extent of the wheels in the discharge direction by up to 15 cm, particularly preferably by up to 10 cm. It is thereby achieved that the preferably laminar mixture discharge from the high-pressure mixing head impinges precisely on the ballast stand in order to ensure a substantially vertically aligned, undisturbed flow through the reactive mixture through the ballast bed. Because with a turbulent, spurting mixture discharge, the reactive mixture would spread far beyond the surface of the ballast structure and the reactive mixture in the ballast stand would almost "run".
  • FIG. 1 Polyurethane reactive components of storage containers via metering units (not shown in the diagram) are conveyed by means of connecting lines 2, 3 to a self-cleaning high-pressure mixing head 1 and mixed there. Subsequently, the liquid reactive mixture 4 above the ballast bed 5 is applied to the ballast structure 6 (ie, the ballast portion of the ballast bed) and allowed to flow through the ballast tower to the planum 7.

  • the rise height Z S of the foamed reactive plastic is about 25 cm. Approximately 30 seconds after the beginning of the reaction, the foaming process is completed and the reactive plastic hardens, forming a vent 9 of reactive plastic in the ballast of the ballast bed in the area of which ballast stones 8 are fixed in position and so can neither twist nor move.
  • FIG. 3 schematically shows a special application of the method according to the invention, namely the underfoaming of a threshold.
