Definitions

  • the present invention relates to a method and a device for the controlled underground driving of pipes in the inaccessible diameter range in accordance with the generic terms of the main method and device claims.
  • a controlled underground pipe advance has been carried out in such a way that a jacking pipe is driven from a dug-out starting pit, in which a pressing device is installed, to a target pit that is also to be excavated, and a control head is articulated on the end face thereof for controlling the heading to the target pit which also carries a drilling tool for working the soil (EP-A-0 100 748, FR-A-2 349 091).
  • the drilling tool either works on the displacer principle or tears open the face of the ground. In the latter case, the drilling tool is coupled to a conveyor string that conveys the soil to the starting pit. To the rear, the product pipes to be laid are gradually coupled to the jacking pipe.
  • the control and actuation mechanism for the control head pivoting is located in the jacking pipe.
  • the actuation lines for the control of the control head and the drilling tool, possibly also the conveyor itself, are lengthened accordingly piece by piece when the product pipes are coupled.
  • the jacking pipe, control head and drilling tool are removed there.
  • What is disturbing in this embodiment is the need to always have to dig a sufficiently large target pit in addition to the starting pit.
  • a further disadvantage of this embodiment is that if the propulsion hits obstacles such as stones or the like that are too large for them to be able to drive around back to the old target direction, pits must be excavated from the surface of the earth at all these points to remove these obstacles. Repairs to the drill head during the advance also require the excavation of a corresponding pit in order to reach the drill head.
  • collapsible and expandable drilling tools are known for drilling tools for earthworks (EP-A-0 065 284, DE-A-2 422 489). These are designed to pierce solid obstacles such as natural stones. They are slidably guided in a carrier tube and can be in a drilling position. be expanded by the drilling diameter corresponding at least to the outer diameter of the carrier tube. After clearing the passage for the carrier tube, such a drilling tool can be collapsed again to a smaller diameter. The collapse and expansion takes place through a controlled rotary movement limited by stops, with which the pivotably mounted drilling tool segments are pivoted accordingly via support and control curve sections.
  • the present invention is therefore based on the task of creating a method and an apparatus for carrying out the method in order to carry out the underground controlled pipe jacking also through any obstacles and through the wall of a target object exclusively from a starting pit.
  • the solution according to the invention results from the characterizing part of patent claim 1, and with regard to the device for carrying out the method it results from the characterizing part of patent claim 5.
  • the drilling tool for earthwork is withdrawn to the starting pit and from there a drilling tool specially designed for drilling through such obstacles is pushed to the obstacle and the obstacle is pierced accordingly.
  • this drilling tool is designed to be collapsible and expandable. In the collapsed state, it can be pushed through the cladding tube. After advancing in front of the obstacle, it is then expanded to at least the outer diameter of the cladding tube and the control head articulated on the first driving cladding tube and thus drills the through-hole in such a large diameter through the obstacle that the subsequent further pre-pressing of the cladding tube is problem-free.
  • the product tube train is then pushed through the cladding tube from the starting pit out of the product tube to the target object, optionally into the perforated wall of the target object, optionally using a seal on the front end of the first product tube of the product tube train.
  • the finished product pipe train is then blocked from moving back from the starting pit and you pull back from the starting pit the now unnecessary cladding pipe train, which of course can be used again and again. If necessary, you can then fill from the starting pit from the annulus created by the retraction of the cladding tube.
  • Another very useful embodiment of the method consists in drilling the target object to form a drill core and pulling the drill core back to the starting pit with the drilling tool and then determining the dimensions of a seal to be placed on the front end of the first product pipe according to the dimensions of the drill core. This gives a seal that is precisely adapted to the diameter and the length of the bore through the target wall and thus acts very reliably.
  • All cladding tubes 3 and 3 ' have such a clear inner diameter that' a train of product tubes 4, which are also to be coupled to one another and to be laid, taking into account in the given example an elastic seal 5 to be arranged on the first product tube 4, through which the cladding tube can be advanced to the collector 2.
  • the various drilling tools associated with the device are also designed so that they can be pushed forward through the cladding tubes 3, 3 'on site and can also be withdrawn from there.
  • FIG. 2 it is shown by way of example that a tubular guide piece 6 is fastened to the front end of the first jacking pipe 3 ', the inner wall of which is designed as a sliding guide 7.
  • the outer ring 9 of a control head is articulated on the tubular guide piece 6 at the front end, for example via a swivel joint 8 located below during operation, which permits swiveling in several axes.
  • a tubular frame 11 which can be pushed back and forth on the outside in the sliding guide 7 of the tubular guide piece 6, are the essential elements of the control and actuation mechanism for the pivoting movement of the control head 10 and also the essential elements for the actuation of the earth-working tool and, if appropriate the earth production to the starting pit.
  • piston-cylinder units 12 For the pivoting of the control head 10 about the pivot axes of the swivel joint 8, several piston-cylinder units 12, one of which is shown in longitudinal section, are provided, for example distributed over the circumference, to be actuated hydraulically from the starting pit.
  • the free end of the piston rod facing away from the piston is articulated to an inner body 13 of the control head 10.
  • the inner body 13 is displaceably guided in an extension of the sliding guide 7 in a corresponding sliding guide 7 'in the outer ring 9 of the control head 10.
  • the outer ring 9 of the control head 10 has an end stop 14 for the advance movement of the inner body 13 together with the tubular frame 11 as well as actuation and control mechanisms.
  • the two sliding guides 7 and 7 ' are bridged by a sheet metal ring 7 ′′, through which the parts can also be pushed.
  • a tapered drill 15 is provided as the earth working tool, which continues backwards in the form of a screw conveyor 16, which travels the soil coming in through the essentially front end of the outer ring 9 and the inner body 13 of the control head 10 Directed towards the starting pit 1.
  • Storage and support of the drilling tool 15 together with the screw conveyor 16 take place in the interior of the tubular frame 11.
  • a pipe string 17 in the exemplary embodiment shown, through which, for example by means of a flushing liquid supplied from the starting pit, that during propulsion the drilling tool 15 drilled soil can be discharged to the starting pit 1.
  • the mechanism described above is essentially limited to the first jacking casing 3 ', with the exception, for example, of the pipe string 17 and all supply lines to the actuating units, for the flushing medium supply and the supply lines for driving the drilling tool including the screw conveyor.
  • the further cladding tubes 3 to be coupled to the first jacking cladding tube 3 ′ normally do not require any guide pieces comparable to the tubular guide piece 6. It is sufficient if its inner diameter is so large that the tubular frame 11 can be easily pushed through with sufficient play.
  • FIG. 3 shows in longitudinal section the special drilling tool that is advanced in front of the obstacle for drilling through such an obstacle.
  • this drilling tool identified as a whole by the reference number 18, is that it can be collapsed into a small-diameter state by being pushed in front of the obstacle in the manner mentioned, it then being able to be expanded again on site and then doing one Ent outside diameter at least speaking the outer diameter of the outer ring 9 of the control head 10 and the cladding tubes 3, 3 ', so that the hole through the obstacle is large enough to then pass through the obstacle with the control head and the cladding tube easily.
  • an outer tube 19 is provided, in which an inner tube 20, limited by stops 21, is rotatably supported within limits, which is connected to a rotary drive 22.
  • cutting ring segments 25 covered with diamond chips are rotatably mounted by means of pins 24, which have eccentric pieces 26 at their free ends, for which control cams 27 are provided in the frontal incisions of the inner tube.
  • the cutting segments 25 have trimmings with, for example, diamond chips on the front and on their outer jacket.
  • the inner tube 20 In the collapsed state of the drilling tool 18, the inner tube 20 is rotated to the outer tube 19 so that it is spaced from the stops 21 ( Figure 4) and the eccentric pieces 26 of the cutting segments 25 inside the recesses in the end face of the inner tube 20, d. H. before the start of the control curve 27.
  • the drilling tool In this collapsed state, the drilling tool can be pushed in front of the obstacle through the cladding tube 3, 3 'and the outer ring 9 of the control head. If the rotary drive, which acts on the inner tube 20, is set in motion, the inner tube 20 rotates in relation to the outer tube 19, as a result of which the eccentric pieces 26 are pressed into the outer position shown in FIG.
  • the above-described drilling tool which can also be constructed differently with regard to its collapse and expansion, for example using toggle levers, is withdrawn to the starting pit 1 through the cladding tube pull, and the drilling tool is then used for soil cultivation, for example as in connection described with Figure 2, pushed back on site.
  • the tunneling now reaches the target object, for example when creating a house connection to collector 2, in this use case of the method and, if water is present, which could occur when drilling through the collector while carrying contaminated soil with it, first of all from starting pit 1 the soil in the area of the connection point to the collector 2 solidifies the drilling tool for the injectors assigned to the soil, so that a consolidation zone 28 forms around the connection point. Then in the manner described the drilling tool for soil cultivation.
  • the cladding tube and the outer ring 9 of the control head 10 now push a drilling tool in front of the collector 2, which is used to drill through the wall of the collector 2 is determined.
  • This drilling tool not shown in the drawing, consists, for example, in a very simple manner of a tube piece which is covered with diamond chips and provided with a rotary drive. If the wall of the collector 2 is pierced with such a piece of pipe, the plaster bored out of the collector wall is located in the tubular drilling tool. This drilling tool is now also pulled back to the starting pit 1.
  • the distance between the starting pit 1 and the collector 2 can also be determined exactly, and in particular due to the presence of the plaster from the collector walls
  • the displacement path can be determined exactly, it must be ensured that, with a sealing sleeve 5 that is precisely adjusted in length, the product pipe pull is only advanced so far that the front end of the first product pipe does not protrude into the collector and here, possibly, as a flow barrier, Deposits produced.
  • the annular space created by the retraction of the cladding tube can still be filled from the starting pit 1.
  • diamond splinters e.g. B. hard metal splinters or small cutting edges to be used.
