Definitions

  • the invention relates to a device for generating a circumferential bore on a laid in the ground line using a Erdbohrwerkmaschines and takes the priority of German Patent Application 100 53 567.4, to which reference is made.
  • a tubular drilling tool with a drive is known, which is placed on the Altteitung and - wegbedorfd means of the drive on the line - rinsed with the aid of front side flushing an annular space around the old line.
  • the drive provided in the drilling tool is replaced by a rod-mediated hydraulic drive, as described in DE 195 04 484 C1.
  • the known from DE 195 22 579 C1 device uses a drive-over head, the old line separates, passes over and covers the old pipe with a cladding tube. The conically shaped override head displaces the earth surrounding the old pipe during propulsion and thereby forms a cavity for the hull or new pipe.
  • the devices described surround the old line annular. This leads to the fact that not only a great deal of effort is needed in the propulsion, but obstacles either not at all or can be overcome only with considerable difficulty. Such obstacles can occur in particular in the form of sleeves, thickenings or repairs on the pipe, but also be formed by pipe branches or pipe bends. In practice, for example, a pipe socket, if it exceeds the pipe outside diameter by more than the inside diameter of the tubular drilling tool, stops the drilling operation.
  • the invention is an object of the invention to provide a device that allows a simple clearance of the laid in the ground line.
  • the invention is also the object of providing a suitable method available.
  • the old pipe is gripped with a drilling tool in the form of an open cuff or a curved blade to more than 50%, advantageously 60%.
  • the drilling tool has a helical configuration, which is particularly suitable for driving over sleeves and branches.
  • the device according to the invention can have outlet nozzles for a rinsing liquid, which can be aligned so that an annular rinsing space is created.
  • the nozzles can form a fan-shaped nozzle ring, which leads to a complete flushing of the old pipe despite the lack of ring closure of the drilling tool.
  • the drilling tool on a cutting surface, with the obstacles, such as branches, can be separated.
  • the device may have a control surface, can be specifically approached with the obstacles and optionally separated with repetition of the process.
  • the particular geometry of the device according to the invention makes it possible to avoid obstacles without difficulty and forcibly follow the course of the old pipe in a preferred embodiment, so that even curvature sections of the pipe are reliably overcome without the drilling tool leaving the pipe route.
  • the invention is particularly suitable for the replacement of long pipe sections, as they are now cleared for the first time without hindrance can.
  • the device according to the invention is suitable for the replacement of old pipes of any material and allows to easily feed new pipes of the same or larger diameter into the earth channel.
  • the device according to the invention has a drilling tool 1 with nozzles 2 and a control surface 3. Due to the geometric configuration of the drilling tool shown in Fig. 1, this has a trough-shaped inner surface 6, which bears against the outer Alt effets- or pipe circumference.
  • the voltage applied to the outer surface of the pipe guide surface is formed by the inner surface 6 of the helically shaped drill head 1.
  • the drilling tool has at the end a cutting edge 8, with the obstacles can be removed from the outer jacket of the pipe.
  • the open design of the drilling tool also makes it possible to avoid obstacles.
  • the nozzles 2 are preferably high-pressure nozzles with which a water jet, a bentonite suspension or another flushing medium is introduced into the annular space.
  • the nozzles are arranged in a ring on the front side of the drilling tool 1 and aligned so that the old pipe is completely washed around (Fig. 3).
  • the drilling tool is connected to a push rod and placed in a starting pit on the exposed there old pipe. Thereafter, the tool 1 is driven by using the flushing nozzles 2 along the pipe by means of a (not shown) thrust drive and the tube completely washed around with the aid of the flushing medium.
  • a (not shown) thrust drive When hitting a Hindemis this is either bypassed by targeted rod-mediated rotation of the drilling tool or destructively overcome in one or more steps by applying the required thrust. After clearing the old pipe, it can easily be removed from the ground and replaced with a new pipe.
