Definitions
- the invention relates to a device for producing a multilayer, in particular a two-layer concrete pipe with a first stand, in which a first drivable compaction tool, for example a press head, is stored, a turntable, on which several form jackets stand vertically and can be swung into a stand in cycles, and a first loading system for pouring a first concrete mix into one of the form jackets.
- the invention further relates to a method for producing a multilayer Concrete pipe.
- Such concrete pipes are used, for example, for municipal and industrial sewerage used.
- the wall of such a pipe meets different functions.
- the wall of the pipe must be static and dynamic loads that act from the outside.
- the inner surface is exposed to the medium to be transported. Therefore are special properties for the inner surface, e.g. Abrasion resistance, acid resistance, Fire resistance and the like, required. It therefore makes sense Wall of the pipe made of several layers, the layers differ from each other by their properties.
- This thin layer of acid-resistant concrete is traditionally used in applied a centrifugal process in which the acid-resistant concrete mixture is placed in a horizontal pipe.
- the work step centrifuging must be carried out until the concrete is at least partially cured so that the tube is in a horizontal position can be removed from the mold without being damaged.
- pipes are single layer Pipes are also often used in vertical manufacturing processes with a press head or The like. With vertically manufactured pipes, the inside surface subsequently applied coatings, or so-called plastic inliners installed. The installation of these sometimes very expensive coatings requires additional Manufacturing steps. In addition, there is no inner, i.e. chemical compound, so that these layers can detach if necessary.
- the object of the present invention is therefore a device and a To provide methods of the type mentioned, with which multilayer Concrete pipes can be manufactured faster and more economically, whereby in particular, the connection between the individual layers improved becomes.
- this object is essentially achieved in that a second driven compaction tool with an outer diameter, the is smaller than that of the first compacting tool, and a second loading system for pouring a second concrete mix into one of the Shapes are provided in the device.
- a second driven compaction tool with an outer diameter the is smaller than that of the first compacting tool
- a second loading system for pouring a second concrete mix into one of the Shapes are provided in the device.

Every stand can also be used have a turntable, this via a suitable transport device are interconnected. After making the outer layer a concrete pipe in the first stand, this is together with the Shaped jacket swung over the turntable into the second stand, in which by means of the second compression tool the inner coating from z. B. acid-resistant concrete. With this arrangement a possibly necessary tool change between the production of the first, outer layer and the second, inner layer of the concrete pipe are eliminated. Leave the cycle times in the production of a multi-layer concrete pipe to shorten itself further in this way.
- the first loading system the first stand and the second feeder the second stand are assigned. Consequently, in this embodiment two stands, each with a feeding system for feeding a concrete mix and have a compaction tool, arranged side by side in such a way that they have a common turntable or two turntables connected to a transport device are connected.
- the first and the second loading system the same stand assign, in which, if necessary, the first and the second alternately Compaction tool are stored.
- the space is used
- the production of a multi-layer concrete pipe helps this embodiment may require a tool change, since the first, outer layer of the concrete pipe is manufactured with a compaction tool, whose diameter is larger than that of the second compacting tool, with which the inner, second layer is manufactured.
- At least one of the loading systems has a concrete silo with assigned filler tape.
- the loading system also by a concrete pump with a pump hose be educated.
- 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 is required to manufacture a multi-layer concrete pipe.
- first and second compaction tools are preferably the first and second compaction tools alternately cyclically in the stand via a quick-change device drivable.
- the change between the first and the second compaction tool can e.g. B. automated, so that the second (inner) concrete layer particularly quickly on the not yet hardened first, outer layer of concrete can be applied.
- a tool change as in the previously described device with one Stand is not required if the second compaction tool is below of the first compacting tool arranged on a common shaft is.
- the first and the second loading system are the same Stand assigned.
- the Material for the inner layer preferably from above through the compression tools driving shaft. A two-layer pipe is thus in one single manufacturing step can be produced.
- This radially adjustable compression tool is thus in its outer diameter variable.
- This allows using the radially adjustable compacting tool a tube with a first inner diameter is first produced. After adjusting the outside diameter of the radially adjustable compacting tool can be in the tube with the first inner diameter another layer with a second inner diameter can be introduced. at In this embodiment, therefore, only one compaction tool is required.
- a particularly smooth inner wall and a homogeneous concrete distribution in the Walls of the pipes to be manufactured can be achieved in that the Compaction tools each a distributor with several, essentially radially acting distributor rollers and a compressor with several, essentially have radially acting press rollers and a smoothing tool.
- the in The concrete filled in the molding jacket is first fed through the distributor rollers of the distributor evenly distributed in the molded jacket and pre-compressed, so that any reinforcement or reinforcement provided by the concrete mix is included.
- the press rollers of the compressor compact the concrete mix then so far that the desired inside diameter of the concrete pipe arises.
- the surface by the smoothing tool which preferably designed as a cylindrical piston and below the compression tool is arranged, reworked.
- the smoothing tool which preferably designed as a cylindrical piston and below the compression tool is arranged, reworked.
- the rollers Skids take care of the distribution and compaction of the material.
- the creation of torsional moments in the manufacture of the concrete pipe with A press head can be avoided by having the distributor distribute each Press head in the opposite direction to the compressor around the longitudinal axis of the shaped jacket rotates.
- the compressor and the distributor can do this rotate at different speeds.
- the speed of the distributor is usually significantly higher than that of the compressor with the press rollers and the smoothing piston. In this way, also in the concrete pipe, if necessary provided reinforcements or reinforcements during the compression of the Concrete mix is not twisted so that it is in its intended position stay.
- At least one compaction tool a spray head for application above the smoothing tool be arranged at least one layer of concrete. Due to centrifugal forces Due to the rotating movement of the spray head, e.g. the second concrete mix can be distributed. Due to the impact speed of the sprayed material on the inner surface of the first layer of concrete Material at least partially compressed. This allows for another distributor and / or a compressor can be dispensed with.
- the object underlying the invention is also achieved by a method for the production of a multi-layer, in particular two-layer, concrete pipe solved, which has the following steps: First, an im Essentially vertical molded jacket on a turntable in one the first stand swung in and the molded jacket with a first concrete mix filled from a first loading system. This first concrete mix is then in the shell by a rotating and vertically movable distributes and compresses the first compaction tool and, if necessary, the Smoothed inside surface.
- a second feeder Before the concrete pipe is removed from the mold, a second feeder a second concrete mix into the essentially vertically standing form coats filled in and the second concrete mix is with a second compaction tool, the diameter of which is smaller than that of the is the first compacting tool, distributed and compacted and, if necessary, the inner surface smoothed before the concrete pipe is removed from the mold.
- This invention The process is characterized in that the molded jacket during insertion and compacting both concrete mixes aligned substantially vertically is so that the pipes thus produced immediately after the compression process and can be removed from the mold before the tubes harden.
- the first compression tool a quick-change device in the first stand against the second compacting tool is replaced and after the second concrete mix filled into the molded jacket and distributed in this, compressed and the The second compaction tool was smoothed over an inner surface Quick change device in the first stand against the first compacting tool is replaced.
- the molded jacket during the manufacture of both layers in its essentially vertical Position in the stand. The shaped jacket is only applied after application all layers of the concrete pipe over the turntable from the Stand swung out.
- first loading system first concrete mix above the first compacting tool in the Fill mold jacket while essentially from the second feeder at the same time the second concrete mix above the second compacting tool through the shaft on which the compaction tools are mounted are fed.
- the compaction tools are among themselves arranged. This will make the second layer immediately after the first Layer spread, compacted and smoothed the inner surface, making a quick-change device for the compaction tool and the two-layer one Pipe can be produced in just one work cycle.
- the outer diameter of the first Compaction tool is reversibly reduced.
- the outside diameter the compression tool is radially adjustable. It is therefore at this method only a single radially adjustable compacting tool needed.
- the first concrete mix with the first Feeding system filled in the molded jacket On the radially adjustable Compaction tool is set a first, larger outer diameter. With this setting, a tube with a larger inner diameter is first manufactured. The compaction tool can then be moved to a starting position to be brought. Now in a further work cycle the second concrete mix with the second feeding system in the mold jacket filled. A second outer diameter becomes on the compaction tool set that is smaller than the first outer diameter. With this attitude then becomes the second inner layer with the smaller inner diameter brought in.
- the method can be carried out in a particularly simple manner without additional devices be when the molded jacket from the first stand essentially transported vertically standing to the second stand and inserted there, before the first concrete mix in the form jacket has hardened.
- the second concrete mixture is then poured into the mold jacket and compacted and smoothed them with the second compressor tool. This eliminates the need to change the compressor tool.
