Definitions

  • the invention relates to a device for underground laying of lines or the like., With a cylindrical jacking body, which receives an axially acting impact tool and in front a preferably interchangeable jacking head and behind the supply lines for their own supply a connection for the pipes, cables and . Like. Has the lines to be laid.
  • the jacking bodies are equipped, similarly to the pneumatic hammers, with a percussion piston that can be pressurized with air, which was previously used coaxially in the jacking body and strikes it through the ground via the firmly supported jack head, designed as a chisel tip, with appropriate soil compaction. It arises an earth tube into which the pipes and product pipes or suitable protective pipes to be installed can be pulled in immediately with the jacking body.
  • jacking devices in the form of press drilling systems which drill the earth tubes with the help of special drilling heads. Due to the necessity of the material discharge via screw conveyors and the high pre-pressing force to be applied, these press drilling systems are very complex and their use is dependent on appropriate support options and spacious construction pits. The high pressures also entail the risk of deformation of the soil surface, so that the use of these devices is only possible with a suitable soil and with a sufficiently large overlap.
  • the invention is therefore based on the object to remedy these shortcomings and to provide a device of the type described, which is simple and robust, can be used effortlessly and skillfully and, due to its good controllability and high performance, a rational, unerring drive guaranteed in a wide variety of soil types.
  • the invention solves this problem in that a coaxial tool receptacle is rotatably and driveably mounted in the propulsion body, on which the striking tool sit eccentrically and the propulsion head centrally.
  • the propulsion body is struck through the ground by means of a suitable striking tool, although the strikes take place eccentrically and in accordance with the rotation of the tool receptacle, also rotating around the propulsion body axis.
  • a smooth rotary motion therefore results in straightforward, high-performance propulsion, since, due to the interaction of the rotary and forward motion, the impacts follow one another along a helical path and are particularly effective.
  • Is according to the invention or the like preferably on the end face with cutting edges.
  • equipped driving head asymmetrical to the axis of rotation on the one hand there is an increased drilling effect of this driving head and on the other hand the asymmetry of the head shape increases the steerability of the driving body.
  • the special design and the shape of the jacking head will depend on the type of soil, so that an appropriate selection of the jacking head used allows adaptation to the prevailing conditions.
  • the jacking body has an outwardly curved jacket in which longitudinal grooves are preferably provided.
  • the cambered shape of the propulsion body favors a change in direction of the body movement, the longitudinal grooves acting in a leading and stabilizing manner for the propulsion body.
  • the tool holder additionally carries a vibrator Product or protective pipes or the like. relieved.
  • a drive motor is supported on the tool holder, which drives a pinion that meshes with an internal ring gear of the driving body, the result is a very simple construction for the rotary drive of the tool holder.
  • the drive does not have to be derived from a drive source provided outside the earth tube, but can be accommodated like the percussion tool directly in the jacking body, which increases the efficiency and, above all, the self-supply of the jacking body, for which only thin and flexible cables or hoses are required , is much easier.
  • the drive motor can be controlled in the sense of a cyclical change in the rotational speed, since the rotation remains upright even during an arc-shaped propulsion, which ensures a correspondingly increased propulsive power regardless of the control process.
  • a transmitter can be installed in the tool holder, which cooperates with an above-ground receiver.
  • This receiver detects the respective position of the jacking body and thereby permits the desired targeted steering of the jacking movement, with the rotary drive being controlled by a control device to correct this steering in accordance with the deviation of the respective jacking body position from a predetermined target position or target direction.
  • a type of directional radio device to specify the desired direction for the jacking body, which direction the jacking body now equipped with a suitable direction finding device is following by compensating for any deviations that occur by countermeasures.
  • one of the feed lines has a circumferential marking
  • the respective rotational position of the striking tool can be easily identified outside the earth tube by comparing the marking with a stationary starting mark, for example on a lining tube, and aligning it for a desired steering movement.
  • a stationary starting mark for example on a lining tube
  • the trailer coupling or the like consists of a clamping ring articulated via a hanger on a holder of the propulsion body. consists.
  • the line parts attached to the clamping ring are thus drawn into the earth tube with sufficient steering movement play from the jacking body.
  • a jacking body 1 which is essentially cylindrical in shape but has a slightly outwardly curved jacket 2 with longitudinal grooves (not shown).
  • a tool holder 3 is mounted coaxially rotatably and drivably in this hollow jacking body 1, a drive motor 4, which drives a pinion 6 meshing with an internal ring gear 5 of the jacking body 1, for the rotary drive.
  • the tool holder 3 carries an eccentrically arranged striking tool 7, for example a jackhammer, and is equipped on the drive side with a drive head 8 which is replaceably seated on the tool holder 3 and in turn as a simple drive tip or, as indicated, as an asymmetrical truncated cone equipped with cutting edges 9 on the end face can be trained.
  • a vibrator 10 is attached, the energy or pressure medium supply of drive motor 4, impact tool 7, vibrator 10 and the like. Via corresponding supply lines 11, which lead to the supply point, not shown, on the rear side.
  • the striking tool 7 When using the jacking body 1, the striking tool 7 is pressurized with pressure medium and thereby drives the jacking body 1 forward through the ground, beat by beat.
  • a simultaneous, even rotation of the tool holder 3, together with the eccentric effect of the striking tool 7, guarantees straight-line propulsion of high performance, the transverse vibration applied by the vibrator 10 facilitating the propulsion and solidifying the resulting tube.
  • the propulsion body 1 traveling through the ground can be used alone or it can be used immediately for pulling in corresponding lines, protective pipes or the like.
  • a trailer coupling 12 is provided on the rear side in the jacking body 1, which consists of a clamping ring 15 articulated on a bracket 14 of the jacking body 1 via a hanger 13.
  • the pipes 16 or the like fastened in this clamping ring 15 are thereby pulled along with the jacking body 1 and, due to the mobility of the connection, can also freely follow a steering-related deviation of the jacking body 1 from the straight path.
  • a transmitter or receiver 17 can be installed in the tool holder 3, which, depending on the respective position, interacts with an above-ground receiver or transmitter and ensures appropriate control of the rotary drive.
  • Suitable control devices allow fully automatic operation that only requires the desired destination entry.
