Definitions

  • the invention relates to a method for cleaning a pipeline with a downpipe, according to which a cleaning tool which can be driven in rotation via a flexible shaft, in particular a helical spring, for removing pipe deposits is subjected to a longitudinal feed running in the direction of the pipe, while at the same time for flushing water to be removed above the removal area flow into the pipeline and flushing water is injected into the pipeline with excess pressure in the outflow direction below the removal area.
  • Pipelines in particular sewage and disposal lines, are increasingly narrowed in their clear flow cross-section due to contamination and incrustation until the resulting quantities of water can no longer drain and there is a backflow and associated water damage.
  • a chain sling which serves as a cleaning tool and rotates via a drivable coil spring, is inserted from above into a downtrend of a pipeline to be cleaned, the chain sling of which hammer parts onto the deposits and work off the wall deposits.
  • the invention is therefore based on the object of eliminating these deficiencies and of specifying a method of the type described at the outset which enables rational and reliable cleaning of a wide variety of pipelines without clogging. or risk of backflow guaranteed.
  • an appropriate device for performing this method is to be created.
  • the invention solves this problem in that the tube deposits are removed in a manner known per se by a milling process with a longitudinal feed in the opposite direction to the outflow direction, for which purpose the milling cutter serving as a cleaning tool and inserted into the pipeline below the downtrend is pulled from the front side in the feed direction and by which is driven rotating in the feed direction. Due to the cleaning process driven upstream, the removed dirt and deposits can be discharged downstream through the already cleaned pipe string and there is no longer a constriction of the pipe cross section along the conveying path, which could lead to blockage. The rinsing water flowing off from above takes away the removal in the direction of flow and the pressurized water sprayed downstream below the tool accelerates and completes this removal.
  • the milling process does not process the deposits and soiling in large parts, but rather in small pieces, which makes removal much easier and ensures clean, complete removal of the material with the help of the rinse water.
  • Pulling the milling cutter together with the correspondingly adjustable drive speed also allows the milling process to be specifically adapted to the prevailing conditions, so that there is a flawless and effective cleaning.
  • the cable feed-related longitudinal feed of the milling cutter can also be fine-tuned to the respective pipeline course, which means that pipe curvatures and other changes in direction in the pipeline can be managed without obstructing the milling cleaning.
  • the cleaning process is carried out in several steps with milling cutters that are gradually enlarged in diameter, and it is always possible to ensure a method that is gentle on both the pipe and the tool.
  • a known milling head which is rotationally symmetrical to the drive axis through the shaft connection, is provided as a cleaning tool, which has the shaft connection on its rear end face and an attachment eye on its front end face, the milling head consisting of a rotating body as a milling body with a generatrix sloping in an arc towards the towing eye, from which knife-shaped knife parts are worked out on the jacket side, preferably running along helical lines.
  • This milling head can be connected with one hand to one end of a cable pull that brings the longitudinal feed and at the other end to a coil spring or another flexible shaft for the rotary drive and, because of its convex basic shape, allows deposits of different thicknesses to be worked off during the longitudinal feed, which convex basic shape is also included proper processing of the deposits in the area of pipe bends u. Like. Allows.
  • the cutting edges which extend obliquely to the axis of rotation, preferably extend helically, bring along with the required high removal effect also a removal effect for the processed material, which together with the rinsing water ensures a perfect, problem-free removal of the removal.
  • the milling body itself can be manufactured efficiently and results in a particularly robust and powerful milling cutter with a long service life.
  • the milling head for attaching to a traction rope is advantageously a rotary coupling that can be connected to the towing eye of the milling head on the one hand, and to the traction rope on the other assigned, which has relative to each other about a rotating axis in the direction of rotation rotatably mounted coupling parts.
  • These mutually rotatable coupling parts prevent the rotary movement of the milling head from being transmitted to the traction cable and allow perfect traction of the rotating milling head.
  • FIG. 1 the cleaning of a pipeline according to the inventive method in the scheme and Figs. 2 and 3, a cleaning tool for performing this method in
  • the wastewater disposal system E of a building G has a pipeline 1 which comprises a downcomer F which ends at the top in a ventilation shaft L and at the bottom converges into a horizontal line H.
  • the pipe deposits A are processed by a milling process with a longitudinal feed V directed from bottom to top, a milling cutter 2 serving as a cleaning tool being pulled in the feed direction by means of a cable pull device 3 and by the rear side in the feed direction is driven in rotation via a drive device 4 by means of a helical spring 5.
  • the pipe 1 is opened at the top in the area of the ventilation shaft L and at the bottom in the area of an inspection shaft R of the horizontal line H and the pipe section to be cleaned is made accessible.
  • a coil spring is inserted from above through the ventilation shaft L into the pipeline 1 and driven into the area of the inspection shaft R via a drive unit installed on the roof, whereupon the upper end of the coil spring is uncoupled from the drive unit and with the traction cable 6 of the cable pull device 3 is connected, so that the traction cable can be drawn in from top to bottom through the pipeline 1 to the inspection shaft R with the helical spring.
  • the coil spring 5 is coupled to the drive device 4, which ensures a speed-controlled milling drive, and is equipped with the milling cutter 2, which in turn is attached to the traction cable 6 with the interposition of a rotary coupling 7.
  • the pull rope 6 is via a correspondingly adjustable gallows 8 of the cable pulling device 3 and can be drawn in by means of an associated motor winch 9 with a controllable pull-in speed. Simultaneously with the winding of the pull cable 6, which ensures the longitudinal feed V of the milling cutter 2 along the pipeline 1, the milling cutter 2 is rotated via the drive device 4 and the coil spring 5, so that milling cleaning occurs.

  • This milling head 13 results in effective small-piece milling of the deposits A within the pipeline 1, the milling head, due to the forward-facing convex shape, being able to easily process deposits of different thicknesses and to follow changes in direction of the pipeline 1 without impairing the milling process.

Abstract

Selon l'invention, pour nettoyer une canalisation (1) comportant une partie verticale (F), on soumet à un avancement longitudinal (V), dans le sens de la canalisation, un outil de nettoyage (2) entraîné en rotation par l'intermédiaire d'un arbre flexible (5) et destiné à enlever les dépôts (A) qui se sont formés dans ladite canalisation. Simultanément à l'évacuation des débris (K), on fait écouler de l'eau de rinçage (W) dans la canalisation (1), au-dessus de la zone d'enlèvement des dépôts et on pulvérise de l'eau de rinçage (W) dans la canalisation (1), avec une surpression, dans le sens de sortie de l'écoulement (S), au-dessous de la zone d'enlèvement des dépôts. Afin qu'il soit possible d'obtenir un nettoyage sans problème, rationnel et adapté au mieux à chaque cas, les dépôts (A) formés dans la canalisation sont enlevés selon un procédé de fraisage, avec un avancement longitudinal (V) se faisant dans le sens opposé au sens de sortie de l'écoulement (S), une fraise (2) servant d'outil de nettoyage étant tirée par le côté avant, vu dans le sens d'avancement (V), et entraînée en rotation par le côté arrière, vu dans le sens d'avancement.
