Definitions

  • the invention relates to a mobile preparation device for excavating soil in a railway track according to the preamble of claim 1, by means of which the excavated soil can be improved and solidified in particular.
  • Such a device is known from DE 43 03 285 A1. That device is assigned to the respective position of the trench excavation device such that it is located above the trench excavation device. This makes it possible to feed excavated soil material directly to the crusher by opening up this material and then transporting it via a conveyor belt to refill the trench behind the trench excavation device.
  • the known mobile preparation device is equipped with aggregates at the front, with the aid of which additives for soil compaction and improvement can be added to the excavated material to be prepared. The aggregates are mixed mechanically with the excavated soil.
  • the well-known mobile processing device is based exclusively on the soil that surrounds the wandering ditch.
  • a drive means separate from the trench excavation device is provided for moving this device approximately synchronously with the trench excavation device.
  • the invention deals with the problem of simplifying the handling of the mobile device.
  • This solution is based on the idea of making the mobile processing device a separable part of the trench excavation device. As a result, the mobile preparation device moves automatically and without an additional running wall together with the automatically progressing trench excavation device.
  • An implementation of the mobile preparation device according to the features of claim 2 improves the soil preparation.
  • White lime, cement and other additives, in particular, are added from the containers to the soil material to be prepared on the conveyor belt.
  • Petrification of heavy metals is also possible. Furthermore, cleaned ballast can be added during processing. This generally applies to waste materials suitable for installation, provided that they are not qualified as unacceptable pollutants for this purpose due to legal regulations.
  • the additives as a whole are those which promote the property that a floor material for a load-bearing floor must have as a track substructure for high-speed train tracks.
  • the mixer with the aid of which the added additives are mechanically incorporated into the soil material, is expediently a tiller known per se.
  • the processing device has external dimensions that lie within the permissible minimum standard clearance of the railway track to be processed.
  • the lower part of a neighboring track to be driven is defined by a fixed shut-off device.
  • the trench excavation device, on which the processing device according to the invention can be placed, works without rail guidance, ie it cannot be moved by rail.
  • the processing device is also expediently designed to be pivotable about a transverse axis.
  • the trench region lying in the direction of progress of the trench excavation device at the front between the lateral knife shields and thus laterally supported is excavated with the aid of an excavator, which in particular can be a telescopic arm excavator.
  • the excavator gives the excavated material directly to the crusher of the processing device placed on the trench excavation device.
  • the ground material broken up in the crusher falls in a particularly homogenized state from the latter onto a conveyor belt which conveys this material to the rear end of the trench excavation device, from where it falls into the open trenches for refilling, which are laterally protected by the rear knife shields.
  • the conveyor belt can be a plate belt.
  • the filled soil material is installed according to the known earthworks guidelines by leveling and compacting.
  • additives with soil-compacting and improving properties are metered into the soil material from containers belonging to the treatment device.
  • the additives are mixed into the soil material to be prepared with the aid of a mixer provided at the rear end of the conveyor belt, which is expediently a tiller.
  • the compaction of the refilled soil material takes place in that it is layered with the help of a swing arm excavator, for example an inclined plane is distributed on which it is compressed with a compressor moving along the inclined plane.
  • the excavator is supported on the refilled soil material and can be moved along the inclined plane.
  • the excavator drive unit can be used to move the compressor along the inclined plane.
  • the compressor can be firmly connected to the excavator. It is in particular a plate compressor, the distance between which can be changed in relation to the drive unit of the excavator. The distance is small when the excavator bucket is working and large when the compressor is in use with the bucket inactive. As a rule, either the bucket or the compressor is used separately from the excavator.
  • a suitable inclination of the inclined plane is about 1: 3 in relation to height to length.
  • a support frame 2 with units for a mobile soil preparation device 3 is firmly placed on a knife shield sheeting as an automatically progressing trench excavation device 1.
  • the processing device 3 consists perpendicularly at the bottom of a conveyor belt 4 running in the longitudinal direction of the track and designed as a plate belt. Between the crusher 5 and the discharge end of the conveyor belt 4, two containers 6 for additives are provided for loading onto the soil material from the crusher 5 located on the conveyor belt 4. The additives added to the soil material on the conveyor belt 4 from the containers 6 are attached to the end of the conveyor belt with the aid of an Tiller 7 evenly mixed into the soil material. The processed soil material arrives from the end mill 7 from the end of the conveyor belt 4 into the area of the progressive trench to be refilled. Guide plates are attached to the side of the conveyor belt. Furthermore, in the feed area of the conveyor belt, the feed material distributing and stripping the feed material (baffles) is provided.
  • the prepared soil material is evenly distributed with the help of a swivel arm excavator 8 and brought to an inclined plane 9 in layers.
  • the inclination of this inclined plane 9 is approximately 1 to 3, 1 being the height unit and 3 the length units.
  • the excavator moves on the refilled soil, whereby it can be moved in particular along the inclined plane 9.
  • a compressor 10 Connected to the drive unit of the excavator 8 is a compressor 10, which is, for example, a conventional plate compressor, a sheep-foot or smooth roller or a vibrator.
  • the type of compactor depends on the soil material to be compacted. By coupling the compressor 10 to the drive unit of the excavator 8, a separate drive unit for the compressor can be saved.
  • the compactor can be designed for the entire width of the soil material to be compacted in the trench.
  • the excavated soil at the front end of the trench excavation device 1 is excavated by an excavator between the laterally supporting knife shields and fed directly to the crusher 5.
  • the relevant excavator 11 working in the direction of progress of the trench excavation device at its front end is supported on the soil outside the progressive trench.
  • the preparation device 3 placed on the trench excavation device 1 can be pivoted as a whole or only with respect to individual units laterally about an axis lying in the longitudinal direction of the track relative to the straight excavation device.
  • Such a pivot axis which is not shown in the drawing, can be provided on both sides of the processing device.
  • the processing device 3 can also be designed to be pivotable about a transverse axis 12 in its central region. Such pivoting is appropriate if the trench excavation device can also be pivoted about a corresponding axis. If the trench excavation device consists of two sections that can also be pivoted horizontally relative to one another, the processing plant can be pivoted in the same way. For this purpose, a correspondingly acting joint can be provided in the transverse axis 12.
  • the conveyor belt 4 can be mounted on one end of it on a horizontally rotatable turntable.
  • width of a trench excavation device can be changed, the same applies to the width of the processing device.
  • the external dimensions of the processing device 3 are dimensioned such that they lie within the standard light space of a track, so that unimpeded train traffic can run on a neighboring track.
  • the processing device 3 may have to be pivoted about its longitudinal axis with respect to a vertically oriented trench excavation device, in order to avoid interfering with the regular light space of the neighboring track being traveled in the area occupied by the processing device 3 with certainty.
  • the device according to the invention enables extremely efficient and energy-saving soil preparation of the substructure of a track.
  • it is not necessary to remove the excavated soil, since after it has passed through the preparation device 3, it is directly returned to the trench to be filled. In this way, there is practically no need to reinstall gravel / sand.
  • the device according to the invention enables an environmentally friendly track construction or an environmentally friendly track renovation. No significant removal is necessary, so that landfill costs are eliminated. Furthermore, no significant new material has to be added. Any additional materials that are usually to be disposed of as waste materials can be added to the on-site soil preparation, provided that these materials are used in accordance with the relevant statutory regulations (e.g. regulations of the German Waste Working Group, in which material classifications are defined, such as assignment values Z0 - Z2 for floors of the technical rules on the requirements for the recycling of mineral raw materials / waste) are permissible for installation. Heavy metals can no longer be eluted. The applicable circular economic waste regulations can be very well taken into account. In a certain sense, the device according to the invention represents a type of waste recycling machine with which the material for a load-bearing earth structure of a track can be created at the same time.
  • relevant statutory regulations e.g. regulations of the German Waste Working Group, in which material classifications are defined, such as assignment values Z0 - Z2 for floors of
