Definitions

  • the invention relates to the use of a device for producing a multilayer concrete pipe with such a compaction tool and to a method for producing a multilayer concrete pipe.
  • Such concrete pipes are used, for example, for municipal and industrial sewer.
  • the wall of such a tube fulfills various functions.
  • the wall of the pipe has to absorb the static and dynamic loads that act from the outside.
  • the inner surface is exposed to the medium to be transported. Therefore, for the inner surface, special properties, such as e.g. Abrasion resistance, acid resistance, fire resistance or the like. Required. It is therefore useful to make the wall of the tube from several layers, with the layers differ from each other by their properties.
  • This thin layer of acid-resistant concrete is conventionally applied in a centrifugal process in which the acid-resistant concrete mixture is introduced into a horizontal pipe.
  • the step of spinning must be carried out until the concrete is at least partially cured, so that the tube can be removed in a horizontal position from the mold without being damaged.
  • horizontal tube making is very time consuming, single layer tubes are used often also produced in vertical manufacturing processes with a press head or the like.
  • coatings are subsequently applied to the inner surface, or so-called inliners made of plastic are installed. The installation of these sometimes very expensive coatings requires additional manufacturing steps.
  • the press rollers can be adjusted via an adjusting lever in their radial orientations.
  • an adjusting lever fixing the threaded bolt is unscrewed from a threaded hole and screwed after adjustment of the adjusting lever in another threaded hole.
  • the adjustment of the press rollers is time consuming and therefore not feasible during the production of pipes.
  • This document also discloses a method for producing a concrete pipe according to the preamble of claim 1.
  • Object of the present invention is therefore to provide a method of the type mentioned, with which multilayer concrete pipes can be made faster and more economically, in particular, the connection of the individual layers is improved with each other.
  • the at least one distributor or press roller and / or the at least one pressing or smoothing piston can be connected to the driven axle via an adjusting device in such a way that the distance between the outer male part surface and the driven axle can be changed.
  • the adjusting device thus makes it possible, for example, to change the diameter of the compacting tool described by the distributor rollers or skids or the pressing rollers in a defined manner to concrete pipes having different inner diameters with the same Manufacture compaction tool. Since it is not necessary for the actuation of the adjusting device, to drive out the compaction tool from the mold shell, can be made without a tool change with the compacting tool according to the invention a two- or multi-layer concrete pipe.
  • the compaction tool first to produce the outer layer of the concrete pipe with a larger inner diameter and apply the inner layer of the concrete pipe with a smaller inner diameter after a reduction in the diameter of the compaction tool.
  • the radial adjustment of the compaction tool for changing the diameter is effected by the distance between the driven axis and the outer lateral surfaces of the rollers, runners or the like. Is varied.
  • the adjusting device may have a slotted guide, which extends in a curved or straight path between two points at different distances from the driven axis, and a slide sliding in the slotted guide block.
  • the driven axle can be connected to a disk or the like, in which a slot is formed as a sliding guide.
  • the journal of a distributor or press roller or a Glättkolbens slides as a sliding block in the slot. Due to the rotation of the compacting tool about the driven axis, the roller or the piston is urged in its rearward in the direction of rotation in the slotted guide.
  • the roller or skid By reversing the direction of rotation of the compaction tool about the driven axis, the roller or skid can be urged into the other end position of the slotted guide, which has a different distance to the driven axis compared to the first position, so that the diameter of the compaction tool by a Reversal of its direction of rotation is changeable.
  • the reversal of the direction of rotation of the compaction tool between two processing steps can alternatively also be used with an adjusting device for changing the diameter of the compaction tool when the adjusting device is formed by a pivoted lever mounted eccentrically with respect to the driven axis.
  • This pivot lever is connected at its end facing away from the bearing with the at least one distributor or press roller and / or the at least one pressing or smoothing piston and pivotable between two points at different distances from the driven axis.
  • the pivotal movement of the lever limiting stop points can be arranged such that contamination of the adjustment is largely avoided by the concrete mixtures, so that no impairment of the exact adjustability of the diameter of the compaction tool occur during operation.
  • the adjusting device has at least one electrically, hydraulically or pneumatically actuatable drive motor, which is assigned to the at least one distributor or press roller and / or the at least one pressing or smoothing piston for adjustment.
  • This drive motor for example a linear actuator, can centrally adjust all the rollers and / or pistons of the compaction tool or can be associated with individual or several rollers or pistons.
  • the power supply of the drive motor by the driven axle which is formed from at least two coaxial and nested hollow shafts.
  • an electrical, hydraulic or pneumatic line through the inner hollow shaft leads to the adjustment.
  • the driven axle is formed by two coaxial, nested hollow shafts, wherein in the inner hollow shaft, a further shaft for driving the adjusting device is provided.
  • the compaction tool can have a distributor with a plurality of substantially radially acting distributor rollers or distributor skids, a compressor with a plurality of substantially radially acting press rollers or compressor skids and a smoothing tool exhibit.
  • the filled into the mold shell concrete is thereby distributed evenly through the distributor rollers of the distributor in the mold shell and pre-compressed, so that any provided reinforcement or reinforcement is included by the concrete mixture.
  • the press rollers of the compressor compress the concrete mixture so far that the desired inner diameter of the concrete pipe is created.
  • the surface is reworked by the smoothing tool, which is preferably designed as a cylindrical piston and arranged below the compacting tool.
  • the smoothing tool which is preferably designed as a cylindrical piston and arranged below the compacting tool.
  • radially arranged skids can also take over the distribution and compression of the material.
  • a spray head for distributing and compacting concrete mixtures may be arranged on the compaction tool above the polishing tool.
  • z. B. be distributed the second concrete mix for the inner layer of the concrete pipe. Due to the impact velocity of the sprayed material on the inner surface of the first concrete layer, the second concrete mixture is at least partially compacted and the connection to the first concrete layer is improved. Consequently, it is possible to dispense with a further distributor and / or an additional compressor.
  • An apparatus for producing a multilayer, in particular two-layered concrete pipe comprises, for example, at least one stand in which a drivable compaction tool is mounted, at least one turntable on which a plurality of mold jackets are vertically intermittently swung into the stand, and at least one charging system for filling at least one Concrete mixture in one of the form coats.
  • at least two feeders are associated with a stand so that different concrete mixes can be processed in the same stand.
  • At least one of the charging systems has a concrete silo with an associated filling belt.
  • the charging system also be formed by a concrete pump with a pump hose.
  • the use of a concrete pump may be sufficient for the supply of the second, for example. Fire and / or acid-resistant concrete mix, of which only a smaller volume fraction for producing a multi-layer concrete pipe is required.
  • the inventive method for producing a multi-layer, in particular two-layered concrete pipe has the following steps: first, a substantially vertically standing mold jacket is pivoted into a stand and filled the mold shell with a first concrete mixture from a first charging system. This first concrete mixture is then distributed and compacted in the mold shell by a rotating and vertically movable compaction tool, and if necessary, the inner surface is smoothed. Before the demolding of the concrete pipe, a second concrete mixture is filled into the substantially vertical mold shell by means of a second charging system.
  • the diameter of the compaction tool is reversibly reduced, so that the second concrete mixture distributed and compacted with the compaction tool and possibly the inner surface can be smoothed before the concrete pipe is swung out of the stand and removed from the mold.
  • This inventive method is characterized in that neither a change of the compaction tool nor a transport of the outer part of the multilayer Pipe is required together with the mold jacket in another stand. Rather, the compacting tool itself can be changed in size before the introduction of the second concrete mixture within the mold shell. After swinging out and demolding the concrete pipe diameter of the compaction tool is then reversibly increased again for distributing and compacting the first concrete mix a new concrete pipe.

  • the size of the circles D R1 and D R2 described by the outer surfaces of the press roller 5 during one revolution of the compacting tool also changes. In this way, different wall thicknesses can be produced with a compaction tool in the production of a concrete pipe without the need for a tool change.
