Definitions

  • the invention relates to methods and apparatus for producing manhole bases with variable Gerinneaus exiten with the features in the preamble of claim 1 and 16.
  • Precast concrete parts such as pipes, manhole elements and manhole bases are produced in large numbers with largely automated systems.
  • the concrete is poured into the mold with simultaneous shaking and compacted.
  • the demoulding and the further transport of the fresh concrete parts to profile rings or pallets takes place immediately.
  • the vibrating press process all mass products of the same shape and structure can be produced efficiently.
  • Manhole bases are also mass products, but the channel has a variety of variants, which does not allow automatic rational production so far.
  • the well element is filled with a curable filler prior to drilling the side openings. After sufficient hardening of this filler, the channel is milled from above.
  • the disadvantage here is that the manhole base is not monolithically produced in one casting and at least two operations for concreting the shaft are required.
  • the milling process from the top takes a very long time, as larger amounts of concrete or filler material must be removed and removed.
  • a manhole blank is formed by compacting the earth-moist concrete. After demoulding the manhole base blank, it stands with its thick base plate (base plate) on the ground. In this position, a raw channel is milled into the still earth-moist (not yet hardened) concrete by means of a milling tool.
  • the disadvantage is that the milling process is greatly affected by the removed concrete and the channel surface is damaged. The suction of the milled, still earth-moist concrete is only partially possible and very expensive.
  • the production of the manhole bases takes place in the vibrating or casting process.
  • the manhole bases are made in reverse natural position in molds.
  • the production of the variable channel is done by stratified removal of concrete also in reverse natural position.
  • the concrete can be removed quickly and without much energy, because the concrete is only partially hardened.
  • the removed concrete falls down by gravity, so that the milling process itself is not hindered by the concrete residues.
  • the concrete removal is collected and used for further processing.
  • the manhole bases are made monolithically from a single casting. For the production of the channels no models are needed. The entire production process can be automated with this procedure.
  • the channels themselves are dimensionally accurate and can be designed to be optimized in terms of flow. Any forms of channels are possible.
  • the spigots of the manhole bases are very accurate, as the manhole bases on the profile rings set in the reverse natural position.
  • the device according to the invention which makes it possible to carry out the methods according to the invention, is characterized in claim 16.
  • Advantageous developments of these devices will become apparent from the claims 17 to 34, the advantages achieved by the design of the device are in the low cost and in the achievable full mechanization of manhole base production with variable channel formation and variable connections.
  • the invention relates to manhole bases 1 made of concrete, which are shaken or cast in reverse natural position in molds 19.
  • the variable channel 3 is not yet made, but only the complete tread surface without channel 13, which is usually conical.
  • the variable channel 3 is produced in a second operation by concrete removal 4, whereby the manhole base is in this process in reverse natural position, so that in a short time large quantities of concrete can be removed, which falls by gravity down and not the milling process with special needs.
  • the rotating cutter 5 is guided and guided programmatically 18 on the concrete surface and the concrete 4,14,16 thus milled in layers.
  • FIG. 2 is the molding device 19 for producing the manhole bases still seen without flumes.
  • the mold can be designed both for the self-compacting concrete pouring method 16 and for the concrete vibrating compacting method 14.
  • the support core 11 is lowered with the lid 12 and the profile ring 6 vertically into the mold jacket 9 and after completion of filling and compacting process of the concrete 14; the manhole base 1 is ejected upwards.
  • the removal of the concrete 4,14,16 takes place in the region of the variable channel 3 after a Operaerhärtung from 1 to 10 hours. Only after a Sectionerhärtung of 1 to 3 hours, the cover 12 can be removed from the manhole base 1, so that the tread surface without channel 13 for concrete removal 4 is accessible. The Generalerhärtung can be accelerated by the manhole bases 1 are passed through a hardener chamber.
  • the cutting tool 47 does not rotate like the cutter 5 but cuts whole layers and pieces out of the partially cured concrete.
  • the concrete removal 4 is effected by at least one rotating cutter 5.
  • the cutter 5 has a diameter of approx. 140 mm and is equipped with 8 to 40 carbide teeth.
  • the cutter 5 can rotate and work both left and right.
  • concrete quantities 4 of about 0.1 to 1.0 dcm 3 per second can be removed so that a variable channel 3 is milled out within 3 to 10 minutes.
  • the hardened concrete 14,16 can be removed quickly and with low drive power and low wear.
  • the manhole base 1 is held in reverse natural position on profile rings 6, this allows for safe transport and accurate position of the manhole bases 1 during milling. In addition, this creates very accurate spikes.
  • the profile rings 6 are removed only after final curing of the manhole bases 1 from the spigot end. Under reverse natural position of the manhole base 1 is to be understood that the spigot 30 shows horizontally or obliquely downwards.
  • variable channels 3 can be produced program-controlled 18 in any desired geometric diversity.
  • the dimensional accuracy and geometry of the variable channel 3 is very accurate, since the semi-hardened manhole bases 1 are already dimensionally stable.
  • the concrete removal 4 of the part-hardened manhole bases 1 takes place at a substantially higher speed than with hardened manhole bases 1.
  • the manhole base 1 is advantageously made of fine-grained material. This has the Advantage that the best possible clean surface is achieved when milling the partially cured concrete, which can be better smoothed by a subsequent smoothing process, in addition to the concrete that is commonly used for manhole bases. So far, a concrete is used for manhole bases, with a grain size up to 16 mm. Overall, all surfaces of the manhole base are better by using the fine-grained concrete.
  • variable terminals which have already been manufactured in molds during the first shaping, are measured and on the basis of these data the milling program for the matching variable channels is produced. This has the advantage that the variable channel 3 is aligned very accurately to the variable terminals 2.
  • variable terminals 2 are no longer manufactured and formed in the first shaping by the Aussparern 10, but also milled with the milling device of the partially cured concrete.
  • the industrial robot 22 is arranged so that with the milling cutter 5 it can mill both the variable channels and all the variable milled connections.
  • the manhole base is also rotated about its vertical axis 34, so that variable milled connections can be attached to the entire circumference of the manhole base.
  • the surface of the variable channel is smoothed immediately after the milling process. In order to improve the smoothing effect, additional water can be sprayed on.
  • a liquid is sprayed immediately after the milling process. This is program-controlled, in a very even and exact layer thickness.
  • the surface of the variable channel 3 is aftertreated by sandblasting.
  • the tread surface 41 may be sandblasted, so that a slip-resistant, roughened surface is formed both in the variable channel 3 and on the tread surface 41.
  • the concrete removal 4 which occurs in large quantities in a short time, is automatically removed by gravity, namely by falling into a container 7.
  • the further transport of concrete removal 4 is easy, for example via a conveyor belt 8, so that these concrete residues 4 can be further utilized in the production machine or mixing plant.
  • the invention further comprises an apparatus for producing manhole bases with the features of independent claim 16.
  • the Aussparkerne 10 are variably attached to the mold jacket 9, so that each connection angle can be realized.
  • the support core 11 has a lid 12 for the formation of the appearance 13, but in the first operation so in the production without channel, wherein the lid 12 is flat or conical.
  • the milling device 17 and / or the cutting device 46 is integrated, which works out the variable channel 3 after a Sectionerhärtung of about 1 to 10 hours.
  • the molding device 19 is designed so that the concrete 14 is compacted by shaking the molding device 19 and optionally by additional pressing of the pressing plate 15.
  • the concrete 14 already has such a large green strength, that immediately after the compression process of Form jacket 9 and the pressing plate 15 can be removed.
  • the Aussparkerne 10 are pulled out, so that they can also be used immediately again.
  • integrated seals in the terminals 2 remain only Aufsteckkerne 20 until the final setting in the concrete part.
  • the manhole base 1 is further transported on the profile ring 6 together with the support core 11 and the lid 12 and optionally passed through a curing chamber, so that the Generalerhärtung takes place faster.
  • variable channel 3 can be made by layering out and / or cutting out of the concrete 4,14,16 ,
  • a plurality of mold devices 19 are required, which are filled with self-compacting concrete 16. After the desired sectionerhärtung of the concrete 16, the support cores 11, the cover 12 and the Aussparkerne 10 can be removed so that here the manhole base 1 is only on the profile ring 6 in the reverse natural position and also the variable channel 3 milled out quickly and easily can be.
  • the manhole base 1 is removed from the mold 9 relative to the top. This is done with the Vertikalhub coupled 44, which pushes the manhole base 1 together with the support core 11, cover 12, profile ring 6 and Aussparkernen 11 upwards out of the jacket 9. This is a very simple and safe demoulding process and the manhole base 1 is very accessible for removing the Aussparkerne 11 and for further transport from the top.
  • a measuring device 27 is provided for measuring the prefabricated variable connections 2.
  • the manhole base 1 is rotated about its vertical axis 34 and scanned with the measuring device, the peripheral surface of the manhole base 1, either by ultrasound or by laser beams.
  • the measurement data of the variable channel 3 with respect to diameter, altitude and angle can be accurately detected, so that the milling out of the variable channel 3 according to the actual dimensions of the terminals 2 takes place.
  • the rotating cutter 5 and / or the cutting tool is guided programmatically with the industrial robot 22.
  • the industrial robot 22 has six axes.
  • the variable channel 3, as well as variably milled connections 24 can be quickly and accurately milled from the partially cured concrete 14, 16. Due to the arrangement of the industrial robot 22 below and laterally to the manhole base 1 can both outside and inside in Manhole base 1 are milled and the concrete removal 4 can fall freely into the sump 29 down.
  • the rotating cutter 5 is fitted with carbide or diamond teeth.
  • the cutting edges 38 of these teeth affect an imaginary sphere 36.
  • a cutting unit 47 is used, which cuts the fine-grained, semi-hardened concrete 14, 16 in layers with the cutting edge.
  • the concrete removal 4 is not crushed and is removed in large quantities and with even less wear.
  • the cutting edge is preferably made of a thin sheet and is circular.
  • the cutting tool 47 is simple and inexpensive and the wear plate 49 can be changed quickly.
  • the smoothing ball 23 is slightly larger than the imaginary ball 36 of the rotating cutter 5. Thus, almost the same program can be traversed for the smoothing process, as in the milling process. Only the feed rate and speed of the smoothing ball 23 is varied. Due to the difference in diameter of the smoothing ball 23 to the cutter 5, the contact pressure is set when smoothing on the concrete.
  • the manhole base 1 produced in accordance with the method and device according to the invention is a monolithic part which is manufactured homogeneously from concrete. Both the channel and the shaft wall are cast or vibrated in one piece. It is a fine-grained concrete 14, 16 used. Grain size about 0 - 4 mm.

  • the entire manhole base 1 has a uniform fine surface structure.
  • variable channel 3 has due to the new process on a dimensional accuracy and surface that was previously not possible. This is particularly due to the exact automatic automatic milling process in the case of semi-hardened, fine-grained concrete 14, 16.
  • variable channels 3 can be improved according to the new method by a further treatment, in particular also because the program-controlled processing exact data on the geometry of the channel 3 are present and so a further automatic machining of the parts is possible.
  • variable channel 3 after complete curing of the manhole bases 1 and turning in a natural position, the Improvement of the surface provided with a coating or mortar, or the surface of the channel 3 is further improved by grinding or milling. In this case, only a thin layer has to be removed, since a geometrically perfect channel 3 is already present, which is merely smoothed.
  • variable channel 3 and also the tread surface 41 can be aftertreated by sandblasting. This creates a roughened, non-slip structure.
  • the new manufacturing process can achieve very dimensionally stable parts.
  • the channel channels 43 are optimally designed in terms of flow, by a simple law, which states that the channel channel axes 42 are always radii (R), which meet approximately perpendicular to the axes of the terminals 2, 24, or perpendicular to the inner shaft wall.
  • R radii
  • This simple law allows only because of the position and the diameter of the terminals 2, 24, the milling program can be automatically generated and calculated, so that the programming effort for the milling program is low.
