Definitions

  • the invention relates to a method for producing concrete pipes according to the preamble of claim 1 and a pipe press for carrying out the method according to the preamble of claim 2.
  • the present invention was therefore based on the object of developing a method for producing the concrete pipes described above, which results in pipes whose inwardly facing surface is largely liquid-tight and has high abrasion resistance. Furthermore, a pipe press should be specified, with the help of which this method can be used directly in one step in the production of concrete pipes.
  • the corrosion-resistant and abrasion-resistant layer on the inside of a concrete pipe already during the manufacture of the pipe, that is to say in a state in which the concrete has not yet hardened.
  • the impregnation liquid penetrates at least 10 mm deep into the concrete mass and hardens there together with the concrete.
  • the protective layer produced in this way has a strength and uniformity which is not known from the concrete pipes impregnated subsequently, ie after curing. Due to its thickness, the protective layer acts as an additional reinforcement of the concrete pipe after hardening. This is an additional advantage of the impregnation process according to the invention, which is not known from the impregnation processes used previously.
  • the tube press has a vertical tube shape 1, in the longitudinal axis of which a shaft 2 rotating in the counterclockwise direction is arranged.
  • the shaft 2 leads from a gear 4 arranged in a gear 3 to a smoothing cylinder 5 which, together with press rollers 6, forms a roller head of the tube press.
  • the shaft 2 is surrounded by an outer shaft 7, which rotates clockwise and leads from a gear 8 in the transmission 3 to the two upper press rollers 6.
  • a tube 9 is guided, which protrudes with its upper end from the gear 3 and is closed there by a rotating device 10, while the lower end of the tube 9 approximately in the radial direction in the middle of the interior of the smoothing cylinder 5 branched outgoing network.
  • the number of distributor lines 11 depends on the diameter of the smoothing cylinder 5 and is on average 4-8 distributor lines. Of course, more distributor lines can be provided for smoothing cylinders with a larger diameter.
  • the distributor lines 11 open on the outer surface of the smoothing cylinder 5 into pretensioning nozzles 13 which lie in an annular channel running along the circumference of the smoothing cylinder.
  • the pipe press works in the following way:
  • a synthetic resin solution is used as impregnating agent for the concrete by means of a feed line 12 via the rotating device 10 Given tube 9 and led under pressure to the biasing nozzles in the annular channel of the smoothing cylinder 5. From the prestressing nozzles, the synthetic resin solution is distributed in the ring channel over the entire circumference of the smoothing cylinder 5 and penetrates into the concrete, which has in some cases already been smoothed but is still moist.
  • the working pressure in the pipe 9 and in the distribution lines 11 is set so that the synthetic resin solution can penetrate at least 10 mm deep into the concrete pipe. By changing the working pressure, smaller or larger penetration depths can be set.
