Definitions

  • the invention relates to a method for deep ground consolidation, in particular for consolidating the underground of railroad track bodies, according to the preamble of claim 1 and a device for performing this method.
  • a disadvantage of these known methods is that time and energy must be expended in order to drive away the excavation or to move the material to be filled in from a remote location to the excavation site for refilling. Landfill space is also required for the excavation to be driven, which is often difficult to find today.
  • the problem with which the present invention is concerned is to provide a better, in particular resource-saving and energy-saving and thus overall more environmentally friendly solution.
  • Shredding of the excavated soil before mixing is necessary if the excavated soil contains soil classes 4 to 7 according to DIN 18300. It is possible to classify the excavated soil before crushing according to soil classes that require crushing and those that do not require crushing.
  • both the excavated soil and the aggregates are mixed in a correspondingly coordinated dosage, for which purpose the individual substances are added in metered form to the mixer in question .
  • the aggregates to be used for solidification are to the person skilled in the art with reference to the one to be processed in each case
  • Soil and the solidification to be achieved in the result are known per se and can be of a mineral, hydraulic and / or chemical type.
  • lime and / or cement with optionally water can be used as additives.
  • a thermal, chemical, biological or washing decontamination can be integrated into the on-site soil preparation.
  • the methods to be used for this purpose are also known per se to the person skilled in the art, so that this need not be explained in more detail here.
  • Which of the above-mentioned decontamination processes is to be used in individual cases depends, of course, on the type of contamination in the excavated soil. In the case of a biological treatment, this can take place in that the additives which bring about the biological purification are only added during the treatment and their effect is only effective in the refilled soil material.
  • a prerequisite for the method according to the invention is a continuously progressing trench, the length of which should be as short as possible so that the excavated soil can be refilled and compacted in the processed form in the shortest possible way.
  • a short, open trench is particularly important and advantageous in cases in which the underground of a railroad track has to be carried out next to a neighboring track that is being used at a close distance. Because then with the open trench care must be taken to ensure that the subsurface of the track being driven does not penetrate into the open trench. In order to avoid this, the progressive trench must always be supported on the longitudinal side wall lying to the neighboring track in these cases.
  • Such support can be achieved, for example, by introducing a supporting wall into the ground before excavating the trench, which later forms the side longitudinal wall lying to the neighboring track when the trench is excavated.
  • a support wall can be introduced into the ground as a lost wall or it can also be designed in such a way that it can be removed after the trench has been refilled.
  • a lost support wall can be achieved, for example, by using a tiller to mill a gap in the ground before digging the trench, which is then poured out with steel-reinforced concrete. This concrete wall can also be secured by tie rods against the subsurface of the neighboring track, next to which the trench is to be drawn along the supporting wall.
  • Such a constant wandering of the support walls can be achieved in that in the longitudinal center of the trench laterally braced support elements are provided, with which a firm support can be achieved between the two side walls of the trench.
  • the bracing of the support elements against the side walls of the trench is released and the support elements are drawn together.
  • the entire unit of the support elements can be advanced or advanced in the direction of the trench.
  • the pulling can be carried out, for example, with an excavator that is located outside the trench.
  • the bracing is expediently carried out via hydraulic drives.
  • the support elements can have movable shields in the direction of the trench progress. These shields can be moved between two predefined end positions. In one end position, the shields are attracted to the supporting element that carries them. The shields are brought into this end position when the support elements are moved in a mutually relaxed position in the direction of the trench progression. As soon as the support elements are then braced again against the longitudinal side walls of the trench, the shields are brought into their second end position, being pressed into the soil to be excavated. The shields are pressed in because the support elements have been advanced so far in the direction of the trench that the shields, in their position in relation to the support elements, have come to rest directly on the soil still to be excavated. The displacement of the shields relative to the support elements is also advantageously carried out hydraulically.
  • the front edge of the shields can be inclined according to the slope angle that results from excavating the soil material.
  • Corresponding shields can also be attached to the support elements at the end opposite the direction of progression of the trench in the same way.
  • the trench roller can be attached to the boom of a telescopic excavator be guided, which is supported on the already refilled and compacted soil.
  • a telescopic excavator is also particularly suitable for excavating soil.
  • a device suitable for carrying out the method according to the invention must consist of mobile units which can follow the continuously progressing trench at about the same time and can each be assigned to the trench opening in such a way that, on the one hand, the excavation can be carried out directly by the excavation device and, on the other hand, the processed soil material also can be returned directly to the trench filling area.
  • the width of the aggregates required for preparing the excavated soil does not at least substantially exceed the width of the trench. This is usually necessary, for example, if the surface of a track body is to be prepared, which is in the immediate vicinity of a parallel railroad track that should also be passable during the preparation time.
  • the method according to the invention can be carried out particularly successfully and economically with a device in which the essential aggregates required for the preparation of the excavation work are stored mobile above the opening of the progressive trench.
  • the mobile unit with the aggregates required for soil preparation it is also possible for the mobile unit with the aggregates required for soil preparation to be stored in a mobile manner on the already filled soil material.
  • the length of the progressing trench be particularly short. In some cases, this avoids side support of the open trench.
  • the wandering hydraulic support device described above can also be used here.
  • this support frame can be applied to a slide, the runners of which are supported on the longitudinal ends of the trench.
  • the sledge can then be pushed in a simple manner as the digging progresses following the digging. The pushing can be carried out, for example, by the excavator carrying out the excavation by simply pulling.
  • the supporting structure can also be supported on the ground outside the open trench by means of wheels.
  • a conveyor belt can be built into the supporting structure, via which the prepared soil material can be distributed in a targeted manner.
  • the conveyor belt can be swiveled horizontally in order to be able to distribute the soil material to be refilled evenly over the width of the trench.
  • a trench 1 which progressively migrates in the direction of arrow A, it becomes at the front in the direction of progress lying end 2 excavated soil material and refilled in prepared form at the opposite end.
  • the depth of the trench shown is approximately two to three meters, although greater depths can also be present.
  • the length of the trench 1 is about seven to eight meters at its base.
  • the longitudinal extent of the trench 1 on the surface measures approximately fifteen meters.
  • the soil preparation plant is supported on a carriage 4 which is supported on the end edges of the trench 1 and on which the individual treatment units are mounted on a support frame 5 above the opening of the trench 1.
  • the individual processing units consist of a material feed hopper 6, which receives the soil material excavated from the bucket of a telescopic excavator 7 and transfers it to a crusher-mixer unit 8 that fulfills the functions of a crusher and mixer.
  • the processed soil material falls from the crusher-mixer unit 8 onto a conveyor belt 9, which leads this material to the rear end of the trench 1 as refill material. So that the material from the conveyor belt can be distributed evenly over the width of the trench, the conveyor belt 9 is pivoted accordingly.
  • the refilled, prepared soil material is compacted in layers in the region of the rear end of the trench 1 using a trench roller 10.
  • This trench roller 10 is guided by the extension arm of a telescopic excavator 11 which is supported on the refilled soil material.
  • the trench roller 10 is covered at the top by a protective roof 12.
  • aggregates such as cement, lime and / or water have to be added for the necessary consolidation of the soil material during processing
  • these aggregates can be fed from a container 13 via a screw conveyor 14 into the hopper 6 for the excavated material to be abandoned .
  • support elements 15 are articulated on the supporting structure 5.
  • the support elements 15 extend essentially over the area in the longitudinal center of the trench 1, which is located between the actual excavation area at the front end 2 and the refill area at the rear end 3 of the trench.
  • the plate-shaped support elements 15 in the present case are adapted in shape to the angle of repose of the front end 2 of the trench 1, i. H. there they have an inclined leading edge.
  • longitudinally displaceable shields 16 are arranged in them.
  • the support elements 15 can be displaced transversely to the longitudinal direction of the trench 1 via hydraulic drives.
  • the support elements 15 are firmly clamped against the trench side walls by the hydraulic drives 17. This bracing was preceded by a displacement of the support elements 15 in the direction of the trench progression.
  • the shields 16 hinged to these elements are in the state in which they are retracted relative to these elements.
  • the shields 16 can be driven in the direction of the trench progression by means of the hydraulic drives 18 provided for this purpose, namely into the soil which has not yet been excavated.
  • the extended state of the shields 16 is shown in FIG. 4b.
  • FIG. 4c shows the state in which the support elements 15 have been pulled off the trench side walls by the hydraulic drives 17.
  • the shields 16 are in a position extended to the support elements 15.
  • the support elements 15 can be moved in the direction of the trench by advancing the slide 4.
  • a correspondingly shifted position of the support elements 15 is shown in FIG. 4d.
  • the shields 16, which were initially brought into contact with the ground up to the open front edge, are brought into this ground with the aid of the hydraulic drives 18 driven in.
  • the support elements have 15 also in the front area a direct support within the ground.
  • the entire unit of the mobile processing plant is located on the edge region of the progressing trench 1 which has already been filled up again.
  • the direction of the trench progress is again indicated by an arrow A.
  • the mobile processing plant consists of two conveyor belts 19 and 20 arranged one above the other.
  • the upper of these conveyor belts is the conveyor belt 19 onto which the excavation of the soil from the bucket of a telescopic excavator 7 is carried out at the end facing the trench 1.
  • the excavated soil reaches a crusher-mixer unit 22 via a funnel 21.
  • a conveyor belt 20 running below the conveyor belt 19 conveys the processed soil material to the rear end 3 of the trench 1 for subsequent compaction .
  • aggregates can also be added to the soil material to be treated via additional devices.
  • the progressive trench can have a particularly short length. In this way it is possible in many cases to be able to do without a lateral support of the trench 1. In principle, however, progressively movable support elements 15 can of course also be used in this embodiment.
