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 usually been carried out in such a way that a jacking pipe is driven from a dug-out starting pit, in which a pre-press device is installed, to a target pit that is also to be excavated, on the front side of which a control head is used to control the jacking to the target pit is articulated, which also carries a drilling tool for working the soil, which either works according to the displacer principle, or tears open the face of the soil and is coupled to a conveyor line that conveys the soil to the starting pit.
  • the product pipes to be laid are gradually coupled to the back of the jacking pipe, and the actuating units for the control of the control head and the drilling tool, as well as, if applicable, the conveyor itself, are lengthened accordingly, piece by piece.
  • the jacking pipe, control head and drilling tool are removed there.
  • the requirement is to always have to dig a sufficiently large target pit in addition to the starting pit.
  • Another 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 circumvented by re-steering 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.
  • the present invention is therefore based on the object of providing a method and a device 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  • the drilling tool for earthwork is withdrawn to the starting pit and from there a drilling tool specially designed for drilling through such obstacles is pushed to the obstacle and the obstacle is pierced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 pushing in front of the obstacle it will be expands to at least the outer diameter of the cladding tube and the control head articulated to the first jacking 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 pipe train passes through the cladding tube from the starting pit to the target object, possibly into the perforated wall of the target object, if necessary using a seal on the front end of the first product tube of the product tube train, 'pushed.
  • the finished product pipe train is then blocked from the starting pit from moving back and you pull back from the starting pit the now no longer required cladding pipe train, which you can of course use again and again. If necessary, you can go from the starting pit through the Withdrawal of the cladding tube created then fill the annular space.
  • 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 tube 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 pipes 4, also to be coupled to one another, to be laid products 4, in the given example taking into account an elastic seal 5 to be arranged on the first product pipe 4, advanced through the cladding tube pull to the collector 2 can be.
  • the various drilling tools associated with the device are also designed to be able to be pushed forward through the cladding tubes 3, 3 'on site and to be able to be withdrawn again 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.
  • the control head 10 For the pivoting of the control head 10 about the pivot axes of the pivot joint 8, for example, several piston-cylinder units 12, one of which is shown in longitudinal section, are to be actuated and distributed 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 In the vicinity of its outer end, has an end stop 14 for the advancing 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.
  • the sheet metal ring also forms a seal for the articulation zone of the control head 10 on the first jacketing tube 3 ′ or its front guide piece 6.
  • 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 inside the tubular frame 11.
  • a pipe string 17 in the exemplary embodiment shown, through which, for example by means of a rinsing liquid supplied from the starting pit, that during propulsion the boring machine witnessed 15 drilled soil to the launch pit 1 can be discharged.
  • the mechanism described above is essentially limited to the first jacking casing 3 ', with the exception, for example, of the pipe string 7' 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, in which case it can then be expanded again on site and then one Outer diameter at least corresponding to 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 becomes large enough to be able to then pass through the obstacle with the control head and the cladding tube cable without any problems.
  • 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.
  • overlapping the inner tube 23 of the outer tube 19 is rotatably mounted by means of pins 24 with diamond chips, cutting ring segments 25 which have eccentric pieces 26 at their free ends, for which 20 control cams 27 are provided in the end-side 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, that is, in front of 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 casing tube 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 drilling tool described above which can also be constructed differently with regard to its collapsing and expanding, for example using toggle levers, is withdrawn to the starting pit 1 through the cladding tube pull and the drilling tool for soil cultivation, for example as in Described in connection 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.
  • the drilling tool for soil cultivation is withdrawn from the outer ring 9 of the control head 10 and the cladding tube 3 ', 3 back to the starting pit and in this application example, the cladding tube cable and the outer ring 9 of the control head 10 now become a drilling tool in front of the Collector 2 pushed, which is intended for piercing the wall of the collector 2.
  • 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 the displacement path can also be determined here in particular by the presence of the plaster from the collector wall, it must be ensured that, at exactly in their Length-adjusted sealing sleeve 5, 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, possibly as a flow barrier, produces deposits here.
  • 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.
