Definitions
- the invention relates to a method for rehabilitating buried Altrohrleitun- conditions in which a connected to a drive bursting or cutting tool or a pipe section from a launch shaft to a target or machine shaft or from a starting pit to a target or machine pit is moved through the old pipeline.
- Such devices are described for example in German patents 196 08 980 C2 and 198 17 873 C2; they consist essentially of a movable by means of a hydraulic cylinder-piston drive on a carriage slide.
- the carriage is provided with pawls, which can bring in the forward stroke of the hydraulic cylinder in engagement with the rungs of a composite of individual sections ladder linkage.
- a bursting or cutting tool can be arranged, with the help of which the old pipeline is destroyed and at the same time the resulting excavated bore can be widened and / or a new pipeline can be drawn into the borehole.
- Drive devices of this type have proven extremely useful; However, they require a machine shaft or a pit, the size of which ments of the drive device and behind the device still enough space for attaching each of a rod section to the device protruding rear end of the drill string allowed.
- the drive device In the old pipe renewal, for example, pressure and sewage pipes from a conventional sewer or revision shaft to the next shaft with a standard diameter of only 100 cm, the drive device, however, occupies a considerable space of the free shaft cross-section, which then for the necessary work, such as Handling the linkage sections or their attachment to the end of the drill string is no longer available.
- Linkage sections is therefore limited to about 50 cm.
- short-length drive devices in a shaft in which the extended old tube axis does not essentially coincide with the shaft diameter or runs through the shaft axis, but cuts the shaft as a secant can not be used because of the miniaturization for design reasons and with regard to to the high
- the problem underlying the invention is to provide a method which leaves more free space in a given shaft (standard shaft) or requires a smaller pit than is the case with conventional methods and drive devices (linkage drive).
- the invention solves this problem in such a way that the linkage drive is at least partially disposed in the old pipeline. In this way, the free space behind the drive increases to the extent that the drive dips into the old pipe opening into the shaft. Accordingly, more work space is available.
- linkage or pipe sections can be dimensioned according to the space obtained longer and / or it can also be renewed such old pipes whose extended axis does not pass through the shaft axis, but the shaft secant-like cuts.
- a particular advantage of the invention is also that the channel no longer destroyed or removed and after the pipe renovation no new channel must be created.
- the linkage drive preferably a hydraulic piston-cylinder unit can be arranged in a casing, which can easily insert into the mouth end of the old pipeline and can be locked there or outside stationary.
- This casing can serve as an abutment for the linkage consisting of individual sections and, for example, can be supported on the shaft wall via an abutment shield. This makes a conventional abutment supported by struts in the shaft superfluous and thus leads to a further gain in space.
- the drive unit is preferably arranged in a tubular housing which may be provided at its rear end with a groove, in which a Verrie- gelungsgabel engages, which rests in operation on the abutment plate and thus the drive unit and the casing under the influence of a in the linkage effective traction fixed.
- the drive unit or with the casing - preferably via struts - a front support piece for a rod locking be connected, which prevents a back movement of the drill string with a drawn tool or pipe section, when the linkage during retraction of the piston Drive unit uncoupled from the drive and therefore is no longer subjected to force.
- the piston rods of the drive unit are preferably connected to a bearing piece for at least one movable pull and at least one also movable push finger.
- the fingers serve as coupling means and can alternatively be brought into a position in which they are in drive connection with the linkage.
- the required movement of the fingers in their working position is preferably done under spring force by means of a collar that both rotate as can also move in the axial direction and is in driving connection with the movable fingers.
- the adjusting ring may have a respect to the pipe or device axis angled extending scenery, in which engages a guide and driving pin.
- the rehabilitation of old pipes is representative of any type of underground pulling or pushing activity, be it for old or new pipes or for the expansion of holes.
- FIG. 1 is a partial perspective view of a bursting device according to the invention in situ
- FIG. 2 is a perspective view of the rear end of the bursting device with the pull fingers in their operative position
- Fig. 3 is a Fig. 2 corresponding representation with the push fingers in their operative position
- Fig. 4 shows the device with retracted piston rods.
- a channel 3 in the form of a conventional inspection shaft with two mutually coaxial opposite mouth openings 2 for a pipeline are a channel 3 and the rear part of a linear drive or push and pull aggregate 4 for a linkage 5 of individual preferably via a pawl coupling according to the German published patent application 199 18 530 A1 releasably interconnected linkage sections 6 and 7 are arranged.
- the channel can be preserved.
- a support of the drive device in the shaft is not required, especially if the center of gravity is located inside the old pipe.
- the linkage 5 is provided at its opposite end of the drive unit with a bursting or cutting tool, not shown, or a pipe section and extends coaxially through the tubular housing 8 of a hydraulic piston-cylinder unit, not shown.
- This drive unit consists of several parallel arranged hydraulic cylinders, for example, four pull cylinders and two for inserting a linkage without tools or pipe section serving pressure cylinders.
- the housing 8 of the drive unit is designed as a plug housing and is located in a liner 9, which is located outside the shaft 1 part 10 projects into the end of the old pipe, not shown.
- the casing is fixedly connected to an abutment plate 11, while a provided with a handle opening 12 locking fork 13 engages in an annular groove 14 in the drive housing.
- the piston rods 15 of the hydraulic drive wear at their free ends a coupling head 16 with a distributor ring 17 for the supply of pressure medium to the piston-cylinder units. This in each case via the hydraulic pipes between the coupling head 16 and the hydraulic cylinders extending piston rods.
- pivotable pairs of fingers 18, 19 are arranged, which can be brought into operative connection with the conductor linkage 5 alternatively.
- the Switzerlandfinderschreibe 19 engage during the working stroke, i. during the extension of the piston rods 15 in a rod openings 20 until they slide during retraction of the piston rods 15 and the return stroke after the stroke reversal as a drag finger on the rod openings 20.
- the push fingers 18 operate when the device is operated, for example, in the reverse direction only when inserting a drill string 5 without tools or pipe section.
- the pairs of fingers are pivoted by means of tension springs in their engagement position when a manually operated collar 21 is rotated. It works in a backdrop
- the pull fingers 19 pull the rod end 5 in the direction of the shaft 1 during extension of the cylinder piston 15, while the push fingers 18 move the rod end strand during retraction of the piston rods 15 in the direction of the ground (FIG. 4).
- the device accordingly has two working directions, for example, for pulling a bursting head through a waste pipe in each case when extending the piston rods 15 or when inserting only the linkage 5 to the start shaft, not shown.
- a further enlargement of the free space compared to conventional methods results from the fact that the device via the abutment plate 11 and the locking fork 13 is supported in a simple manner on the shaft wall and therefore does not require abutment struts, as in conventional devices and methods are common.
