Definitions
- the invention relates to a method for the hydrodynamic removal of impurities in the interior of pipelines, in particular for the renovation and cleaning of water-bearing pipelines in domestic and industrial areas, according to the preamble of patent claim 1, as well as a device suitable for carrying out the method according to the preamble of patent claim. 6 ,
- liquid or flowable materials such as paint, mortar and the like are disposed of through the drain, where they narrow the flow area of the pipe after its hardening similar to the described incrustations.
- liquid or flowable materials such as paint, mortar and the like are disposed of through the drain, where they narrow the flow area of the pipe after its hardening similar to the described incrustations.
- full closures of pipelines can be found where concrete already accidentally enters a pipeline during the construction phase of a building. If this remains unnoticed until the concrete has hardened, the defect only becomes noticeable when the building is put into operation. A refurbishment is then often only possible at great expense by renewing the pipeline. State of the art
- hydrodynamic pipe cleaning is known, which has established itself especially in the channel cleaning.
- DE 103 23 298 A1, DE 1 165 945 B 1 DE 197 03 317 A1 and DE 295 13 288 U1 may be mentioned as state of the art.
- a flushing head introduced into the pipe to be cleaned is supplied with pressurized cleaning liquid via a connected flushing hose.
- the cleaning liquid is not only used to clean the inner walls of the tube, but at the same time generates a rebound effect based feed movement of the flushing head in the pipe to be cleaned.
- the rinsing heads have radially obliquely rearwardly directed recoil openings, so that with exit of the high-pressure liquid jets from these openings on the one hand the dirt on the pipe inner walls are rinsed off and, secondly, the flushing head undergoes an advancing movement due to the repulsive force of the cleaning liquid.
- the flushing head therefore only has to be introduced into a starting opening and then works by itself through the piping system before the flushing hose together with the flushing head is manually or mechanically retracted again to the starting opening in the final operation.
- a rinsing head is also already known, in which, in addition to the recoil openings, a forwardly directed nozzle opening generates a pressure jet.
- Such devices have in common that most of the working fluid needed for the feed and is introduced at high speed against the direction of movement of the flushing head in the pipeline.
- the object of the invention is to provide a method and a device, with which incrustations in pipelines caused by incrustation, deposits, concrete closures, root ingrowths and the like can be removed quickly and efficiently and at the same time gentle on the tube and economically.
- the invention utilizes the kinetic energy of a fluid jet impinging upon an impurity under high pressure and high velocity to eliminate the disturbance.
- the invention is characterized in that the feed force for the pressure jet nozzle is generated solely by means of a push rod.
- the kinetic energy inherent in the pressure jet is therefore fully and effectively translated into work to eliminate the impurity, so that lower pump or compressor capacity is sufficient to achieve excellent remediation results compared to known high pressure wash techniques. So it is achieved with less total energy a better work result.
- This opens up the possibility of dimensioning the device-related equipment such as the compressor for generating the necessary conveying and cleaning pressure or the pressure jet nozzle smaller, which proves to be advantageous both in the purchase and handling of the equipment.
- the pressure necessary for the invention depends not only on the selected nozzle and tube geometry crucial also of the type, in particular the material to rehabilitating pipeline.
- For high-strength steel pipelines it is possible to work with water pressures of up to 300 bar in the remediation operation, while the sometimes very brittle PVC pipelines in the domestic area should only be exposed to reduced water pressures of up to 150 bar during cleaning.
- the operating pressure for use in the domestic sector is below 250 bar.
- Another advantage of the invention results from its universal applicability.
- defects regardless of whether it is a simple soiling with grease, faeces, paper, root system, etc., or hard pipe wall deposits, such as lime or urine brick, cement, mortar or concrete, quickly with a device and be removed reliably.
- the invention is capable of successively removing full closures made of concrete, for which purpose the operating pressure is advantageously increased to 250 bar to 500 bar.
- the targeted use of the invention in the field of impurity is by inserting a connected to a pressure hose pressure jet nozzle by means of a push rod to the point of failure, then by establishing a predetermined distance of the pressure jet nozzle to the point of failure and by subsequently pressurizing the pressure jet nozzle via the connected pressure hose with a pressurized Working fluid reached.
- the size of the distance depends on the jet angle of the pressure jet nozzle, the outlet opening of the pressure jet nozzle being so far away from the defect spot, that the pressure jet emerging from the pressure jet nozzle at the point of failure covers the entire inner circumference of the pipe.
- the pressure jet nozzle is pushed into the pipeline with the aid of the push rod in the direction of the pipe's slope, ie in the direction of flow, so that the pressure jet is discharged together with the dissolved incrustations in the direction of the duct system. Since there is no backward directed jet of pressure in the invention, there is thus no risk that liquid will escape at the access opening to the pipeline and cause damage there.
- a suitable embodiment of the invention provides for connecting the pressure jet nozzle to the push rod via a 180 ° bend in order to change the orientation of the pressure jet. This guarantees that during the hydrodynamic application no liquid and impurities escape at the housing-side pipe ends.
- the pressure jet emerging from the pressure jet nozzle is a rotating spot jet in a preferred embodiment of the present invention, but may also be a fixed jet.
- the impinging pressure jet effectively splits the adhering deposits without damaging the pipe wall.
- the push rod for inserting the pressure jet nozzle of a device according to the invention in a pipeline is characterized by a compressive strength and flexural rigidity, which are sufficiently large to absorb the pressure-dependent recoil and torsional forces from the pressure jet and at the same time to transmit feed forces to the pressure jet nozzle. Since in most cases the pipeline to be rehabilitated has one or more changes of direction in the section from the insertion opening to the point of failure, in addition to the pressure stability, the bowability of the push rod is another determining factor for the suitable bending stiffness of the push rod.
- Suitable push rods are made for example of glass fiber reinforced plastic with a diameter of 5 mm to 12 mm and can be formed by either axially assembled rod or rod-shaped elements or a quasi endless rod, which is unwound in the required length of a reel. With such thrust rods, pressure jet nozzles can be pushed into pipes over lengths of up to 150 m and more.
- a push rod as a propulsion-generating means also brings with it the advantage that the operator at the site the pressure jet nozzle with muscle power or motor driven starting from any inlet opening, selectively pushed into the pipe system through bends and branches forward until the pressure jet nozzle finally the Pipe section has reached with the impurity.
- the reaching of the defect is monitored either "online” using a mounted in the immediate vicinity of the pressure jet nozzle camera system or "blind” determined by abutting the pressure jet nozzle at the fault.
- the push rod can now be removed to unfold the optimal cleaning performance first by a predetermined distance from this blockage point, namely by retraction, ie opposite to the direction of insertion or, when using a 180 ° - tube bend, by further insertion in the insertion direction by the pressure jet nozzle through the narrowed or blocked section.
- the pressure jet due to its high impact energy, crushes the incrustations, deposits or the like and rinses them away in the flow direction of the tube.
- the push rod gives the operator a feedback and thus allows a precise and sensitive guiding of the pressure jet nozzle within the pipeline, both forward and backward.
- the front of the pressure jet nozzle end portion of the push rod has a lower bending stiffness on as the remaining push rod.
- a steel compression spring which is fastened with its first end to the pressure jet nozzle and with its second end to the push rod.
- the pressure jet nozzle can be used in an advantageous embodiment of the invention within a housing.
- the housing has, for example, the shape of a hollow cylindrical sleeve, in the receptacle of which the pressure jet nozzle can be inserted axially and fixed by means of radial threaded screws or clamping pins.
- the housing may also be formed by a plurality of shells, preferably two half-shells which, when joined together, surround the pressure jet nozzle and leave only the area of the nozzle opening and the connection to the push rod free.
- pressure jet nozzles can also be used which have a nozzle insert inserted in the nozzle body and determining the spray steel geometry. To change the spray jet geometry, it is therefore only necessary to replace the nozzle insert instead of the entire nozzle body.
- the pipe cleaning device may additionally comprise a tubular running gear, on which the high pressure cleaning nozzle itself and optionally the subsequent longitudinal portion of the Duckschlauches are arranged.
- the chassis has an integrated drive, such as electric drive, for automatically driving on the pipe system.
- the finding of the defect and thus finding the position up to which the pressure jet nozzle in the first step of the invention must be inserted into the pipe is greatly facilitated by the optional use of a pipe inspection camera, which is mounted in the vicinity of the pressure jet nozzle and in the direction of Pressure jet shows. About a connected to the camera video data line along the pressure hose back to the insertion opening of the invention Device is performed, recorded by the camera video images of the pipe interior are displayed to the operator on a corresponding monitor. So not only can the defect be found and analyzed easily, but also the removal of the defect can be monitored online.
- the components to be introduced into the tube comprising a pressure hose, a push rod and, if appropriate, supply lines for the camera system, are advantageously connected to one another, so that virtually a combined strand is created.
- these components can be selectively connected at axial distances with longitudinal restraint or guided within a tubular envelope. In this way, not only the handling of the device is facilitated, but the lines is protected in the case of full wrap from damage and contamination.
- the individual components such as pressure jet nozzle, compression spring, push rod, camera and the like are connected to each other by means of detachable bayonet or other types of quick connectors. This allows the rapid replacement of non-functional components, the simple conversion of the device for a different purpose using the same parts and the space-saving stowage of the device for transport to the job site.
- a centering aid may be provided in the manner of a union nut or sliding sleeve, which surrounds the high-pressure cleaning nozzle on the outer circumference and lifts by support on the pipe inner wall, the outlet opening of the pressure jet nozzle on or in the vicinity of the pipe longitudinal axis.
- a union nut or sliding sleeve which surrounds the high-pressure cleaning nozzle on the outer circumference and lifts by support on the pipe inner wall, the outlet opening of the pressure jet nozzle on or in the vicinity of the pipe longitudinal axis.

- the method and / or device can also be used to clean ground canals and to remove ingrown shrubs or tree roots.
- the pressures used are below 250 bar, but can reach up to 600 bar and more for special applications (eg full closure with high-strength concrete). Decisive for the upper pressure limit is the strength of the pipeline, which must not be damaged.
- the outlet openings of the pressure jet nozzles vary in the order of 0.2 mm to 1, 2 mm, preferably from 0.3 mm to 0.7 mm.
- the demand for working fluid is normally between 10 l / min and 25 l / min.

- the device 4 depicted in FIGS. 1 to 4 comprises a pressure jet nozzle 5 in the form of a spot jet rotation nozzle, which has a central opening 6 at its tip end, from which a working fluid emerges in the form of a single concentrated punctiform and thus high-energy pressure jet 7.
- the angle ⁇ at which the generated pressure jet 7 leaves the frontal central outlet opening 6 with respect to the longitudinal axis of the pressure jet nozzle 5 is referred to as the jet angle and amounts to 15 ° to 45 °, depending on the nozzle geometry used.
- This obliquely emerging pressure jet 7 rotates while maintaining the jet angle ⁇ about the longitudinal axis of the pressure jet nozzle 5, so that the result is a closed circular line as the spray pattern.
- the device 4 according to the invention can also be operated with pressure jet nozzles 5 which have other jet patterns, for example an elliptical line, a circular spiral line or other closed lines.
- pressure jet nozzles 5 which have other jet patterns, for example an elliptical line, a circular spiral line or other closed lines.
- the pressure jet nozzle 5 is connected to its rear end to a pressure hose 8, which is to a compressor, not shown, outside the Piping leads and is pressurized from there with a working fluid.
- a working fluid is preferably water used. More generally, the working fluid is a fluid that may optionally be supplemented with abrasive solids.
- the push rod 9 is made of glass fiber reinforced plastic and serves to apply feed forces to the pressure jet nozzle 5, to which the push rod 9 is inserted manually or by motor in the piping system.
- pressure hose 8 and push rod 9 are longitudinally positively connected with each other at predetermined longitudinal intervals, which can be done most easily by wrapping with an adhesive tape. It is also possible to guide the pressure hose 8 and push rod 9 into the rehabilitation area within a common hose-like sheath 10, for example within a heat-shrinkable tube, whereby additional protection against damage or soiling is achieved.
- the longitudinal section of the push rod 9 lying directly in front of the pressure jet nozzle 5 is formed by a compression spring 11, which has a lower bending resistance than the remaining push rod 9.
- a compression spring 11 which has a lower bending resistance than the remaining push rod 9.
- a sleeve-like coupling piece 12 To insert the compression spring 11 in the device 4 is seated on the end of the push rod portion 9 made of fiberglass reinforced plastic, a sleeve-like coupling piece 12, in which the compression spring 11 is axially inserted with its end and secured against withdrawal.
- the opposite end of the compression spring 11 is rigidly connected to the pressure jet nozzle 5, for which purpose a sleeve 13 is welded to the pressure jet nozzle 5, in which the compression spring 11 is inserted with its end and fixed.
- the pressure jet nozzle 5 is not coupled directly to the pressure hose 8, but via an intermediate sleeve-shaped receptacle 14.
- this serving as a connection adapter receiving sleeve 14 can be depending on the present constipation situation, the z. B. characterized by the pipe diameter, the clogging material or the Verstopfungsab march, a correspondingly adapted pressure jet nozzle 5 quickly and easily remove and remove.
- radially continuous grub screws 15 which engage in corresponding radial openings or grooves of a Einsteckfortsatzes the Druckstrahldüse 5, be solved before the Pressure jet nozzle 5 pulled out and a new nozzle can be inserted into the receiving sleeve 14.
- the illustrated embodiment of the device 4 includes a camera 16, the video signal recorded via a video data line 17 for display to a non-illustrated TV unit located outside the pipeline system transmits.
- the connection of the camera 16 to the push rod 9 can be seen particularly clearly in FIGS. 3 and 4.
- the camera 16 is connected to the push rod 9 restrained.
- the secondary sleeve 18 is welded to the camera 16 for this purpose.
- the video data line 17 emerging from the rear end of the camera 16 continues together with the push rod 9 and the pressure hose 8 inside the tubular sheath 10.
- the device 4 according to the invention With the pressure jet nozzle 5 is first pushed so far in the (partially) clogged pipe 1 with the compressor off until the pressure jet nozzle 5 has reached the impurity.
- the device 4 according to the invention generates only an obliquely forward, i. directed in the direction of insertion pressure jet 7, which normally has in the flow direction 3 of the pipeline 1.
- the insertion of the pressure jet nozzle 5 thus takes place actively with the help of the push rod 9, which is sufficiently pressure-stable due to its bending stiffness to apply a sufficient feed force to the pressure jet nozzle 5, but at the same time is sufficiently flexible to follow the course of the pipe even in areas of bends and branches can.
- the pressure jet nozzle 5 is withdrawn from the impurity by the distance A, before the pressure jet nozzle 5 is pressurized with working fluid.
- the insertion direction coincides with the flow direction 3 of the pipeline 1. Since the pressure jet 3 forward, i. directed in the direction of insertion, the working fluid can drain together with the dissolved incrustations 2 in the flow direction 3 of the pipe 1. However, if only the way through the (partially) blocked pipe is opposite to its direction of flow available, ie in a downpipe for example by a corresponding basement connection from bottom to top in the building, for example, because pushing in the direction of flow is not possible because of the absence of the respective rental party is, then such a device 4, as shown in FIGS.
- the invention provides for the use of a 180 ° tube bend which is interposed between the pressure jet nozzle 5 on the one hand and the push rod 9 or pressure hose 8 on the other hand.
- the orientation of the pressure jet 7 is rotated so that the working fluid and the comminuted impurities in the flow direction 3 are disposed of even when the pressure jet nozzle 7 is pushed in against the direction of flow 3 of the tube 1.

- FIGS. 6 to 8 show an embodiment of the invention in which the pressure jet nozzle 5 is arranged within a housing 20.
- the housing 20 consists of two half-shells 21 and 22, which are constructed substantially mirror-inverted and can be assembled with the aid of centering bolts and screws precisely to a whole.
- the housing 20 encloses a rotationally symmetrical cavity along the axis 23, which is open towards the front sides of the housing 20 and which serves to receive the pressure jet nozzle 5 (FIG. 8).
- the cavity is composed of a cylindrical portion 25 of smaller diameter, an axially adjoining substantially conical portion 26 and a second cylindrical portion 27 of larger diameter.
- the frontal opening of the section 27 is narrowed by a circumferential annular web 28.
- the housing 20 is divided in the longitudinal direction in a cylindrical central portion 29, from which the housing 20 tapers to both sides.
- the angle of inclination of the bevels 19, 24 with respect to the axis 23 is between 20 ° and 35 °.
- the central part 29 is provided with parallel to the axis 23 runners 30 on which the housing 20 is supported on the pipe inner wall and thereby reduces the sliding resistance.

- housing with a smooth surface, ie without runners, is encompassed by the invention.
- FIG. 8 The combination of the housing 20 with a device according to the figures 1 to 5 is shown in Figure 8. It can be seen how from the housing 20, namely of the section 27, the pressure jet nozzle 5 is enclosed substantially free of play. In this case, the annular web 28 engages in a corresponding recess on the pressure jet nozzle 5, so that an axial fixation of the pressure jet nozzle 5 between the annular web 28 and section 26 is given.
- spacer rings may be inserted between the pressure jet nozzle 5 and the inner circumference of the section 27 in order to be able to insert smaller pressure jet nozzles into the housing 20, even in diameter.
- the pressure jet nozzle 5 At the lying in the housing interior end of the pressure jet nozzle 5 includes a compression spring 32, which in turn embodies the more flexible part of the push rod 9. On the pressure jet nozzle 5 associated end of the compression spring 32 is fixedly seated a ring 33 which fills the conical portion 26 positively and so a tension and pressure-resistant locking the compression spring 32 in the housing 20 causes.
- the compression spring 32 extends through the cylindrical portion 25 therethrough and extends with its lying outside of the housing 20 end into a receiving bore of a sleeve-like coupling piece 34, where it is firmly anchored. From the opposite longitudinal end of the coupling piece 34 extends a passage 35, which merges in its further course in the receiving bore.
- a coupling piece 34 in the longitudinal direction penetrating channel which serves to guide the pressure hose 8 into the interior of the compression spring 32, where the pressure hose 8 is guided axially to the pressure jet nozzle 5.
- the coupling piece 32 also has an axial blind bore 36, in which the glass fiber reinforced plastic existing part of the push rod 9 is tension and pressure resistant attached.
- a receptacle for a camera can be integrated in the housing 20.
- the recording in the manner of a cylindrical recess can thereby emerge monolithically from the housing wall and allows axial insertion of the camera.
- Supply and data lines for the camera are advantageously guided in such an embodiment in addition to the pressure hose within the compression spring.
