Definitions

  • the invention relates to a method for the production of preferably cylindrical, hollow structures, in particular manholes, which are generally used for irrigation or drainage, as a control part or for fitting, with the steps listed in the preamble of claim 1.
  • Shafts are currently being built using a process in which a piece of pipe is first closed from below with a base plate.
  • the pipe section consists of asbestos cement.
  • the required number and size of coupling couplings are permanently bonded or cemented in place.
  • Such a prefabricated shaft is now brought to the construction site.
  • the height of the pipe section delivered to the construction site may not exceed 100 cm. If the pipe section had a greater height of, for example, 200 cm to 500 cm, the worker who created the flume would have to climb into this pipe section himself and in this case - since he requires a footprint - could initially only shape half of the flume. After this first half has a sufficiently high stability, the worker could finish on these places and then the other half of the channel.
  • This method of producing a manhole channel would not only be a very cumbersome, but also a very time-consuming and therefore expensive procedure. This means that the height of the pipe section, namely 50 cm to 100 cm, must not be exceeded.
  • the required height of the shaft which exceeds the dimension of 50 cm to 100 cm, is achieved by a corresponding number of spacer rings of different heights to be installed at the construction site, with intermediate rings to be arranged between them.
  • the conical manhole neck with further support rings forms the end with the interposition of a suitable transition ring.
  • the manhole cover is placed on this arrangement.
  • a shaft constructed according to the above method causes high costs due to the concreting work to be carried out at the construction site and the large number of complex individual parts that can only be assembled at the construction site.
  • such a shaft is not adequately secured against the risk of water penetrating into the shaft due to its numerous individual parts that are difficult to seal properly. Since the individual parts are not rigidly connected to one another in this shaft, there is finally the risk that the individual parts will yield in the direction of the earth pressure when the earth pressure acts on one side of the shaft while filling the construction pit into which the shaft has been inserted.
  • Another shaft on the market is designed as a pure sewage shaft. This does not bring satisfactory results in the area of the installation of large pipes, seals of the lower channel part as well as the installation of different connection materials for different casing pipes, such as cast and / or plastic pipes, etc., so that the area of this manhole is in the dimensions of 100 cm up to 120 cm in diameter.
  • this shaft brings with it a very large sealing problem for structures in a horizontal installation, especially if the bushings on the end plates are still to take up mechanical loads, such as shocks.
  • the manhole manufactured in accordance with AT-A-365 694 has a base body which is coated with its tubular element on the outer circumference of a supporting concrete slab of a channel unit with a suitable two-component adhesive.
  • the base body is lowered over the channel unit in such a way that the surfaces covered with the two-component adhesive face each other. These are the load-bearing surfaces on which the channel unit and the base body of the known shaft are inseparable.
  • a joint created during manufacture is filled with shrink and crack-free, acid-proof, liquid-tight, quick-setting adhesive mortar.
  • the invention has for its object to provide a method with which it is possible to manufacture structures, in particular shafts, which are generally used for irrigation or drainage and in electricity, gas and telephone networks, and in the production of which the disadvantages occurring in the prior art are avoided, it being in particular made possible to manufacture the structures mentioned inexpensively in any required size in an absolutely tight manner.
  • a waterproof slab is usually made of reinforced concrete, which is done in the factory.
  • the watertight plate is then connected to a watertight base body, usually a cylindrical tube part.
  • the pipe part is provided with recesses and / or openings, for example for connecting connecting lines. This activity is also carried out in the factory.
  • the waterproof slab, which is usually made of reinforced concrete, and the waterproof base body or the waterproof pipe are then irreversibly connected to one another by filling in a joint that occurs between the two parts.
  • the joint is filled with materials for tensile and pressure-resistant connections, such as non-shrinking grout.
  • a sealing joint is provided when the plate and the base body or the tube are assembled at the factory. This is usually filled with a permanently elastic material, for example a polyurethane / tar combination, but in any case is sealed, the base body or the tube part not being completely lowered onto the surface of a protruding area of the plate.
  • a region of the base body can be roughened at the factory before the parts mentioned are assembled. This area is generally within the joint, which is grouted with materials for tensile and pressure-resistant connections, such as non-shrinking grout. In addition or instead of roughening, other surface treatments that improve adhesion can also be carried out.
  • a channel is advantageously introduced on the plate before or after being joined to the base body.
  • This channel will usually connect the recesses or openings on the base body with one another. In this way, the finished structure or shaft only needs to be excavated or the like on the construction site used and to be connected with the connecting lines to be connected. In this way, the workload on the construction site is further reduced.
  • both on the plate and in the base body preferably internals from prefabricated, usually waterproof parts, such as GRP, half-shells made of fiber cement, stoneware or concrete, can be used in a hardened surface or in masonry.
  • further recesses and / or openings and / or fitting fittings or the like can preferably be provided in the plate at the factory, which are used with regard to the intended use of the building.
  • the base part which is usually made of reinforced concrete, fiber cement or materials such as GRP, PVC, PE or simple concrete, is preferably factory-made in the recess (s) or opening (s) with one or more pipe sections Mistake.
  • the pipe sections have a connection area, which is preferably inserted essentially integrally into the base part by means of a two-component adhesive.
  • connection options for various uses can already be provided in the factory, which are absolutely tight and very resilient.
  • a tubular sleeve for example made of fiber cement, can also be used, preferably at the factory, as the tube piece.
  • connection area of each pipe section in question can be equipped, for example, with ribs, grooves or the like, as a result of which the mechanical durability of the connection to the base body can be advantageously influenced.
  • a grout can be poured into the pipe section, which is inserted into the opening on the base part or in the shaft, the shape being based on the outside of the pipe section, while the shape on the inside diameter depends on which pipe type and which pipe material or which pipe diameter should later be connected to the shaft.
  • This adhesive bridge can be designed differently, for example by a surface structure of the inner wall of the pipe section or by an adhesion-promoting single or multi-component material, for example made of plastic.
  • the grout should have very good flowability and a controlled expansion when it is ready for processing.
  • the grout should have high initial and final strengths. It is very important that the grout is essentially free of shrinkage. High resistance to frost and various chemicals is also an advantage.
  • a permanently elastic and circumferential seal can preferably be used between the pipe section and the shaft connection piece be provided, which adheres to the adjacent parts. In this way, the seal is anchored in the connector.
  • a prefabricated shaft sealing element can also expediently be at least partially poured into the grouting mortar. Prefabricated shaft sealing elements of this type are used for connecting line pipes.
  • Additional tightness in turn provides a preferably permanently elastic, all-round seal, which is arranged between the prefabricated shaft sealing element and the pipe section and can also be anchored in the grout.
  • an adapter pipe piece that protrudes on the connection side can be integrally cast in the grouting mortar on the pipe or line connection side.
  • This adapter pipe piece made of plastic is preferred.
  • the adapter pipe piece should protrude so far that a sleeve or a double sleeve of a pipe, preferably made of plastic, can be slipped over the protruding end of the adapter pipe piece without any problems.
  • the pipe to be connected can then be connected to the adaptation pipe piece without any problems using conventional sealing measures.
  • an all-round, preferably permanently elastic seal can be arranged on the line connection side between the adapter pipe piece and the pipe piece, which in turn can be anchored in the grout.
  • a manhole with a reinforced concrete cover plate can preferably be arranged at the factory at the upward-facing end of the base body with the interposition of a seal.
  • a shaft tapering part for example a conical shaft tapering part
  • the conical shaft tapering part is also arranged with a seal on the base body.
  • a building according to the invention or a shaft according to the invention, in which the appropriate measures for the use have already been carried out in the factory, can be used with minimal effort and permanently tightly and without problems for all conceivable purposes in the field of civil engineering.
  • a shaft is shown schematically, which is generally identified by the reference numeral 10. This shaft was manufactured in the factory using the method according to the invention.
  • a watertight plate 12, in particular made of reinforced concrete, is manufactured in the factory. This is usually done by pouring workable concrete into a mold that contains a steel network that is poured into the workable concrete. As soon as the concrete has set, the plate 12 is assembled with a waterproof pipe part 14.
  • the tube part can be provided with recesses 114 and / or openings 114, for example for the connection of connecting lines, or be equipped.

  • a sealing joint 18 remains between the plate 12 and the tubular part 14.
  • This is usually sealed with a permanently elastic material, in particular a polyurethane / tar combination.
  • the permanently elastic material is introduced into the sealing joint 18 before the assembly and then the plate 12 and the tube part 14 are assembled. Spacers between the plate 12 and the tube part 14 ensure that the permanently elastic material is not completely pushed out of the sealing joint 18.
  • further internals 28 can generally also be placed on prefabricated parts such as GRP, half-shells made of fiber cement, stoneware or concrete on a base on the plate 12.
  • the internals 28 are generally connected to the plate 12 by fastening them using concrete or masonry, at the same time creating the shaft floor 22, the so-called berm.

  • the protruding area 30 on the plate 12 gives the shaft produced by the method according to the invention a greater or lesser buoyancy depending on the subsurface. This means that if the subsurface is not suitable for supporting the weight of the shaft that rests on its base, the area 30 is designed to be correspondingly large, as a result of which the weight of the shaft is distributed over a larger base.
  • the conical shaft tapering part 56 which is attached by means of seals 54, is provided with crampons 8, which enable a controller or worker to enter the shaft and to get to the berm 22 comfortably and safely.
