Definitions
- the invention relates to a method for stabilizing the ground level of a track, wherein the ballast is continuously picked up underneath a track and optionally cleaned, while at the same time the ground level exposed below the track is mixed with additives and leveled and compacted to form a protective layer, whereupon the ballast is applied the new protective layer is thrown off, and a machine for carrying out the process.
- the excavated earth is transported upwards and falls onto a conveyor belt, which simultaneously transports the bedding residues from the sieve. Subsequently, this material can either be thrown off the track or placed in a conveyor, which can also be loaded via a container containing additives and binders.
- the resulting mixture of soil, bedding residues, aggregates and binders is laid out in the track bed on a flexible boom in the working direction in front of the discharge point of the cleaned ballast and mixed by means of a motorized rotating body, after which the mass is compacted or stabilized by a vibrating plate.
- This method is relatively complicated or complex with regard to the machine construction, which also makes it susceptible to faults.
- EP 0 135 478 A1 a method for stabilizing soft floors for the purpose of improving their load-bearing capacity is known. After removing the layers covering the subgrade, the underlying soil is prepared using the local mixing method, whereby the incorporation of binders such as cement and lime, as well water and reinforcement particles are added.
- GH-PS 595 512 describes a method and / or a device for strengthening the surface of a formation layer.
- a diffusible hard foam is applied in the unexpanded form on the formation and foamed into a stable, seamless tape.
- the object of the present invention is now to provide a method of the type described at the outset or a machine with which better and simplified stabilization of the ground level of a track is possible or the formation of a protective layer can be carried out more quickly and easily.
- the uppermost layers of the soil are torn open immediately after the ballast has been removed and the aggregates are introduced into the cracks in the same work step, this ensures particularly good and uniform mixing of the components and increases the effectiveness of the mixing process.
- the method ensures, regardless of a different composition of the soil, an optimal and highly uniform setting of the materials forming the protective layer and reliably prevents the mixture from being too dry or too liquid.
- the design of a machine according to claim 6 for carrying out the method offers the particular advantage that the facilities required for processing the soil are fixable and usable without influencing the equipment used for ballast cleaning.
- the arrangement of mixing elements which can be immersed in the earth planum enables a simplified and quick mixing to be achieved without time-consuming absorption and further transport of the uppermost layer of planum to be processed.
- the further embodiment of the machine according to claim 7 enables the exposed soil planum to be loosened uniformly and simultaneously over its entire width and, above all, at the desired depth, which can be set differently depending on the requirements and is normally approximately 10 cm.
- the spraying of the water-lime mixture which is important for the load-bearing capacity of the sub-base layer, can be accomplished without special technical effort.
- the design of the compacting device described in claim 15 enables the problem-free rolling up of a water-impermeable membrane made of plastic onto the formation protection layer.
- This membrane can be reinforced on both sides by a polypropylene mesh to increase the tensile strength and covers the entire crown of the formation with a width of approx. 5 m.
- a development specified in claim 16 facilitates or simplifies the introduction of the formation protection film in particular in that the work progress is not impaired when the end of a film roll is reached, since the second roll is immediately available for the continuous unwinding of the protection film.
- the design of the machine according to claim 17 ensures that the track is raised sufficiently in the entire work area for the unimpeded use of all work aggregates required for ballast clearing and stabilization of the level, while at the same time increasing safety in the work area.
- a further embodiment of the invention according to claim 18 has the advantage of ensuring the uninterrupted workflow while avoiding breaks for the material supply.
- FIG. 1 and 2 shows a track construction train 1 has a centrally arranged machine 2 for ballast bed cleaning with an elongated machine frame 4 mounted on running gears 3, which is equipped with a clearing chain 5 for receiving ballast 6 to be cleaned from a track 7 and for dropping the Gravel is equipped in a screening plant 8.
- the resulting spoil is transported via a conveyor 9 to a spoil loading system 10, which consists of a number of similar silo wagons 11 connected by means of continuous conveyor belts, which are arranged upstream of the machine 2 in the working direction indicated by an arrow 12.
- each mixing device 15, 16 is arranged with respect to the working direction directly behind the clearing chain 5 on the machine frame 4 and are approximately mirror images of the longitudinal axis of the machine or track.
- Each mixing device 15, 16 has a beam-like support frame 24 running in the cross-machine direction. These are detachably connected to each other at their opposite ends, while at the other end on the outside of the machine they are each articulated to a support body 26 via a parallelogram linkage 25.
- the support bodies 26 are mounted on the machine frame 4 and are designed to be rotatable about a vertical axis by means of a drive 27. Another drive 28 is used to adjust the height of the mixing device 15, 16 relative to the machine frame 4 and is also connected to the support body 26.
- trough-shaped tear teeth 29 are provided which lie next to one another in the cross-machine direction and are directed obliquely downwards or forwards.
- Each tear tooth 29 has a channel 30 which is assigned to an opening 31 in the support frame 24. Via a flexible line 32 and an associated line 33 fastened to the machine frame 4, these openings 31 or the channels 30 can be filled with cement, which is conveyed out of the silo wagons 18 with the aid of the compressor unit 19.
- a horizontal swivel arm 34 is provided for each longitudinal side of the machine, which is mounted on the support frame 24 via a vertical axis 35.
- a drive 36 By means of a drive 36, the free end of each swivel arm 34 can be swiveled back and forth in a horizontal plane and thus covers approximately half of the earth level 14.
- spray nozzles 37 are arranged on the underside of the earth, which have a flexible line 38 and an associated line 39 fastened to the machine frame 4 are connected to the tank truck 20 and can be fed by means of the pump station 21.
- the free end of each swivel arm 34 is equipped with downwardly projecting mixing elements 40 which can be rotated about a vertical axis 42 by means of a drive 41.
- the compacting device 17 is located behind the mixing device 15, 16 in the working direction and has a horizontal compacting plate 43 which extends in the transverse direction of the track and is formed in two parts 44, 45 which can be releasably connected to one another.
- the outer ends of the compressor plate 43 are each articulated via a parallelogram linkage 46 on a longitudinal side of the machine frame 4, with a drive 47 for the height adjustment the compression device 17 is used opposite the machine frame 4.
- the compacting device 17 is provided with a holder 48 which is provided for receiving three film rolls 49.
- the latter are arranged one behind the other with respect to the longitudinal direction of the machine and are aligned with their axis of rotation 51 in the transverse direction of the machine and contain the plastic film 50 to be rolled onto the stabilized earth planum 14.
- the machine 2 is also equipped with two lifting units 52, which raise the track 7 in the area of the working units in a raised position hold on and enable the unhindered use of all units.
- the conventional clearing chain 5 arranged below the track 7 removes the ballast 6 from the track bed with continuous work priority and thus exposes the ground level 14.
- the ripping teeth 31, the swivel arms 34 and the compressor plate 43 are pivoted into the working position below the track.
- the earth planum 14 is loosened by the subsequent tear teeth 29 of the mixing device 15, 16 to a depth of preferably about 30 cm, cement being simultaneously introduced through the channels 30 into the furrows of the loosened earth planum or being blown in by means of the compressor unit 19.
- lime concentrate mixed with water which is mixed with water, is applied to the ground level 14 by means of the pump station 21 via the spray nozzles 37.
- the cement and lime requirements can be varied automatically so that - regardless of the different composition of the soil - a homogeneous, equally resilient protective layer is always created. Furthermore, the moisture content of the soil can be measured in the area of the plowed earth planum and, accordingly, the amount of water to be added can be determined.
- the resulting mixture of earth, cement, lime and water is now mixed in place by the rotating mixing elements 40, with the drive 28 being able to precisely control both the thickness of the layer to be mixed and the depth of penetration of the tear teeth 29 or via a control device 53 is adjustable.
- the compression of the upper formation layer is carried out by the compression device 17. The degree of compression can be controlled using the drive 47.
- the slope of the formation surface required for proper drainage of the formation is automatically created by a corresponding inclination of the mixing devices 14, 15 and the compression device 17.
- the water-impermeable plastic film 50 is deposited on the now stabilized formation protection layer by a film roll 49 in the entire width of the earth formation 14, to which the cleaned ballast 13 can be pivoted back and forth Ballast straps 55 is dropped. If the entire film is unrolled from a film roll, work can continue with the second roll located on the holder 48. A sufficient number of additional film rolls 49 are carried on a loading surface 54 on the machine 2 during use.
