Definitions
- the invention relates to a device according to the preamble of
- cables are cables of any kind (electricity, water ).
- Propulsion rocket and flushes the soil material, so for example, the earth, away from the front of the rocket.
- the propulsion rocket is flushed in this way and can be moved along the existing cable.
- the hose has another function, because it can remain in the ground and in turn receive one or more lines in the sense of a cable channel. While in an embodiment according to DE 19802691 C (or the next discussed EP 0710863 A) the cables present in the ground had to be cut through in a starting pit and the propulsion rocket had to be plugged on, the cable can remain undamaged and retain its function according to the abovementioned document. This is achieved by the division of the propulsion rocket in two half-shells, which are placed in a starting pit on the continuous cable and on the end of the hose and then connected together. The closed-walled hose lies next to the cable and is thus pulled in alongside the cable.
- EP 0710863 A relates to the installation of a cable duct around a cable.
- the cable channel may be formed as a hose and has a rigidity that allows insertion, feeding or advancing in the ground, the cable is used to guide.
- a nozzle head is provided, the water is supplied to flush the head area under pressure. This passes in the annular space between the cable and the concentrically advanced hose or cable channel to the nozzle head for the flushing process.
- EP 0353442 B describes a ram boring machine which has over
- pressurized impact piston features. It rides concentrically on an old pipeline and works along it. A pull-down tube is pulled by the ram boring machine over the end capped cable. From this, the old pipe can be pulled out piece by piece.
- the invention aims to obtain an existing cable undamaged, so track the propulsion rocket cable without abrasions or the like, at the same time to reduce the force required for the feed and apply a hose on the continuous cable. This is achieved with a device of the type described above by the characterizing features of
- the shared propulsion rocket forms the
- the ball head with driving head fits the Rocket during the feed optimally to the curvatures in the course of the cable.
- the slotted tube can be pulled over the continuous cable and used as a transfer means for the feed and finally as a cable channel for easier removal of the cable reusable in long lengths, for cable replacement and for pulling additional cables.
- Hose have latching elements for irreversible connection of the flanks.
- Such a hose may be formed with a wall thickness of 1 cm.
- the hose is suitable for pushing forward and for supporting the work of the propulsion rocket.
- the hose is initially as a role next to the starting pit, where a compressor for the hydraulic hammer devices in each of the two half-shells of the rocket is placed.
- the hose is spread open to be slipped over the continuous cable and connected to the propulsion rocket can. That's it
- Hose over the cable to a wrapper to each other are available.
- the roller guide can be designed as a frame with, for example, three rollers mounted according to an equilateral triangle, with the cable passing through at the center of the equilateral triangle.
- the roller guide or the frame with the roller guide is placed in the starting pit and the rollers are driven by hydraulic motors directly to the rollers.
- FIG. 1 shows a schematic diagram of a propulsion rocket in a simplified oblique view
- Fig. 2 as a detail to Figure 1
- Figure 3 shows a divided propellant head according to the invention
- Figure 4 shows the arrangement of the device in a launch pit
- 6 shows a form-locking connection on the slot flanks of the hose
- FIG. 7 shows a funnel-shaped guide piece for threading the hose
- FIG. 8 shows a roller guide with driven rollers for a hose.
- a propulsion rocket 1 is a propulsion rocket 1 divided into two half shells 2, 3, to each of which at the front end a likewise divided propellant head 4, 5 is connected.
- the propellant head 4, 5 is removable and interchangeable with alternative embodiments (Fig. 3).
- Hammer devices 6, 7 (Fig. 3) are installed, which drive the propulsion rocket 1 along a cable 8 by impacts in the longitudinal direction through the soil.
- the propulsion rocket 1 can return-preventing lateral
- Fig. 3 shows a split propellant head 14, 15 on a split
- the propulsion rocket 1 can better follow any radii of curvature of the cable 8. It also abrasions, damage or even separations are prevented on the cable, since the resulting retroactive forces are transmitted through the ball optimally to the cable.
- the propulsion rocket 1 is designed in a variant so that it pulls a hose 18 through the loosened soil in the course of their forward movement. A piece of such a hose 18 is shown in Fig. 5.
- the tube 18 is slotted in the longitudinal direction (longitudinal slot 19) and there are complementary locking elements 20 provided on the flanks (Fig. 6).
- Fig. 4 shows the propulsion rocket 1 already at work and can see the redrawn hose 18.
- the tube 18, which comes from a hose coil outside the starting pit 21, is spread along its longitudinal slot 19 in the starting pit 21 and thus passes over the cable 8.
- a hinge 23 (shown symbolically) allows the opening and closing of the guide piece 22 so that it can be placed around the cable 8.
- Fig. 4 is still a compressor or a hydraulic pump 24th
- the propulsion rocket 1 and its hammer device feeds and rollers 26 in a frame 27 by hydraulic motors (not shown) drives.
- This frame 27 (FIG. 8) is designed such that two of the rollers 26 grip under the tube 18 in a V-shaped manner.
- the frame 27 is closed by a bracket 28 with a third roller upwards.
- the three driven rollers 26 push the hose 18 along the cable 8 into the loosened soil.
- the thrust forces can be supplied to the hose 18 of the propulsion rocket 1, so that the propulsion rocket 1 is supported at work.
