Description

The invention relates to a process 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 assembly.

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. In the pipe section that forms the manhole base body or in the walls of the factory, 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.

There, the shaft flume is inserted into the prefabricated shaft with the required curvature and slope. A manhole base of this type has been described in the magazine "Installateur, Klempner, Zentralheizungsbauer (IKZ)" 1971, Issue 18, page 44.

In order to make the channel easier to make, 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 creating the channel would have to climb into this pipe section himself and in this case - since he requires a footprint - could first only form half of the channel. 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.

To make matters worse, the use of pipes with a nominal diameter of more than 400 cm according to the previously described method is practically impossible is, since larger diameters of pipes or connecting lines cannot be produced in this way, there are absolute fastening and installation problems.

It is not necessary to prove that 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. In addition, there is a risk that the flume to be created at the construction site will be shaped improperly due to the external influences there. In addition, 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.

As a result of the fact that the manholes constructed using the known method are always finished under open sky and in particular the channel that has just been produced must have set in place so far that it can be protected against the ingress or escape of liquids with the aid of suitable sealing agents , such as bitumen, tar and the like (which in turn also require time to dry) can be protected, conventional shaft construction is very weather-dependent and therefore difficult for the clients and contracting companies involved to calculate, both in terms of time and from a cost perspective.

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 jacket 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. In addition, this shaft brings with it very large sealing problems for structures in a horizontal installation, particularly if the bushings on the end plates are also to take up mechanical loads, such as, for example, shocks.

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 manufacture of which the disadvantages occurring in the prior art are avoided, in particular making it possible to produce the structures mentioned inexpensively in any required size in an absolutely tight manner.

It is also an object of the present invention to use the above-mentioned object in particular for all pipe materials and all diameters, currently up to approximately 250 cm or 300 cm, that are used on the market in such a way that the individual parts of the components in question are absolutely rigid statically firm and watertight connection also in extreme cases and under dynamic load in the long term.

The object on which the invention is based is achieved for a method according to the invention by the subject matter of claim 1.

Appropriate process variants are defined by the features in the subclaims.

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 watertight plate, which is usually made of reinforced concrete, and the watertight base body or the watertight 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. According to the invention, 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 sealed.

In this way, it is possible to completely prefabricate the relevant structures in the factory, possibly even completely prefabricate them with built-in installations, as can be seen from the features described below. Advantageously, with such prefabricated structures or shafts, it is possible to allow extremely short insertion or transfer times on the construction site, so that the construction site can only be regarded as an obstacle for a short time, as a result of which the costs incurred can be considerably reduced. In addition, security aspects become extremely cheap influenced, especially in these types of work, which require special bracing and formwork, often because of the large dimensions of the structures, the open spaces and reinforcement of the trench walls that are necessary in the construction group complicate the work and hinder it to a considerable extent.

In addition, it is advantageously possible to ensure a constant quality for the production carried out completely in the factory, since the manufacturing plants are generally also equipped with test centers for monitoring. In addition, uniform manufacturing conditions are always reproducible during the manufacturing process, which is not possible on site, on the construction site, if only because of the most varied weather conditions.

In order to produce an improved strength of the connection between the plate and the base body, 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.

At the same time, of course, other internals designed for the intended use of the structure can be used on the panel before or after being assembled with the base body. This is particularly advantageous in view of the fact that the structures or shafts mentioned are also suitable for use in district heating, for gas, telephone or power lines. Special connection elements or the like can be provided for this. Since the building according to the invention or the shaft according to the invention fulfills the criteria of absolute tightness, it is thus possible without problems to use the shaft produced by the method according to the invention almost universally.

Of course, all of the listed measures for manufacturing the structure or the shaft are preferably produced in the factory, which is an exceptional feature of the present invention.

In addition, 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. In addition, 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.

This ensures that connection options for various uses can already be provided in the factory, which are absolutely tight and very resilient.

In a further embodiment, a tubular sleeve, for example made of fiber cement, can also be used, preferably at the factory, as the tube piece.

The 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.

In order to improve the tightness and the mechanical strength along the interface of grout / pipe section, it is advantageous to provide an adhesive bridge. 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. In addition, 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. These desired properties are required for use both in the joint occurring between the plate and the base body and in the area just mentioned in order to achieve the advantages mentioned. However, other materials which have the properties mentioned can also be used here without further ado.

The use of a fine, one-component and hardened grouting mortar based on cement, which is based on the leaflet "Grouting mortar", leaflet for the application, acceptance and testing of mixed grouting mortars from the German Concrete Association e.V., has proven to be particularly useful. Because shrinkage-free grouting mortar is used, it is possible to at least partially cast-in manhole connections on the pipe connection side.

As an additional measure to further improve the tightness, 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.

Just as a manhole connection piece can be poured into the grouting mortar, 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.

In order to connect plastic pipes to the building or to the shaft, 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. As a rule, 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.

Here, too, to further improve the tightness of this connection, 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.

In order to connect concrete or reinforced concrete pipes to the shaft, it is particularly advantageous to anchor an all-round sealing element in the grouting mortar in the connection area in the connector at a position in the grouting mortar in which the seal is able to fit into a groove formed in accordance with the seal Grip pipe or otherwise perform a sealing function.

Here it is of course also possible to permanently connect watertight connections to the pipe section on the building or the shaft to connect gas, telephone and electrical lines.

To complete the structure or shaft according to the invention, 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.

If the base body has a larger diameter, it is advantageous to arrange a shaft tapering part, for example a conical shaft tapering part, at the upper end of the base body, which leads the base body into the entry opening with the reinforced concrete cover plate. The conical shaft tapering part, for example, 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.

In Fig. 1, 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.

First, 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. The pipe part 14 is usually prefabricated parts made of fiber cement. After assembly at the factory, a resulting joint 16 is cast with materials that ensure a tensile and pressure-resistant connection. For this, e.g. B. non-shrinking grout very suitable. The assembly process takes place in such a way that 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. For this purpose, the permanently elastic material is introduced into the sealing joint 18 before the assembly and then the plate 12 and the pipe 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.

Subsequently, 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.

Any roughening 20 is provided in an area in which the base on the plate 20 overlaps with the pipe part 14. 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.

The intermediate piece 58, which is also generally made of concrete or fiber cement, forms the transition to the entry opening 51, which is covered with a reinforced concrete cover plate 52. A seal 57 is generally provided between the reinforced concrete cover plate 52 and the frame of the opening 51, in particular when the shaft serves as a control shaft for water, telephone, gas or electrical lines.

Corresponding to the use of the shaft 10 produced according to the invention, line connections 114 are also provided.

As can be seen in FIG. 2, the line connections 114 can be designed differently. For this purpose, further details will be given in connection with FIGS. 5 to 10. The channel 28 inserted at the factory can be clearly seen, which is connected to the plate 12 via the material for producing the berm 22. The protruding area 30 of the plate 12 is indicated by a dashed line. The shaft shown in FIG. 3 is also produced by the method according to the invention. Here, a further recess or opening 114 is inserted into the plate 12, which is designed according to the appropriate use of the shaft 10.

The detail indicated in FIG. 3 by reference number 100 is shown in an enlarged form in FIG. 4. Between the area 30 or the plate 12 and the pipe part 14 or the material that fills the joint 16, the sealing joint 18 filled with a sealing compound can be clearly seen. In the area 20 on the pipe part 14, bumps are attached which improve the mechanical adhesion of the material with which the joint 16 is filled. The material of the berm 22 can be seen above the base of the plate 12, in which the channel is embedded.

5 shows a manhole manufactured by the method according to the invention. in which a fiber cement tube sleeve 116 is inserted in an opening 114 in the tube part 14 of the shaft in such a way that an adhesive joint remains between the tube sleeve 116 and the edge of the opening 114 and is filled with a two-component adhesive 126 in a tight and mechanically stable manner. An adhesive bridge 115 made of materials that are identical or comparable to the abovementioned is provided in the interior of the pipe section 116. This adhesive bridge 115 provides better adhesion between the pipe section 116 and the grout 128, which is poured into the interior of the pipe section 116 by means of a molded part (not shown). A ready-made shaft sealing element 132 has been anchored in the interior of the pipe section 116 at the same time as the grout 128.

In order to largely prevent the ingress of water via the grouting mortar 128 between the prefabricated shaft sealing element 132 and the pipe 116, a permanently elastic, all-round seal 120 can be provided on the pipe connection side. This can be anchored in the pipe section 116 when the grout is poured into it.

Of course, the line connection on the shaft 10 can be made particularly easily before it is permanently fixed with the two-component adhesive 126 in the opening 114 in the shaft 10.

If the line connection is fastened in the opening 114 in the shaft 10, then a pipe can be connected to the finished shaft sealing element 132 on the pipe connection side without problems. Additional all-round permanent elastic seals can be used Come into play. The line connection described above can be used particularly well for connecting pipes made of stoneware with BKL and BKK pipes, PVC, PE, PVC Ultra-Ripp- and GFK, etc. The finished shaft sealing element 132 is made of a material that is particularly easy to connect to the pipe material. The prefabricated shaft sealing element 132 is preferably made of the same material as the pipe to be connected to the shaft.

In FIG. 5, as also in FIG. 6, the berm is identified with the reference symbol 22 in accordance with the other figures. The channel is generally designated by reference number 28.

6, the connection of a line 130 made of cast iron is provided. In order to connect a cast iron connecting pipe 130 to the shaft 10, a pipe section 116 is inserted into an opening 114 in the shaft. The opening in the shaft 10 is slightly larger than the pipe section 116, so that an all-round adhesive joint 114 is created between the connecting area 135 of the pipe section 116 used and the edge of the opening 114 in the shaft 10. As soon as the tube piece 116 is arranged in the correct position in the opening, the remaining adhesive joint in the opening 114 is filled with a two-component adhesive 126. The use of the two-component adhesive 126 ensures a permanently tight connection between the pipe section 116 and the fiber cement pipe 112 of the shaft 10. The pipe section 116 used is preferably also made of fiber cement, although other materials such as stoneware, GRP and the like can also be used. These materials are also suitable for the base part or tube part 14 of the shaft 10.

The inner wall of the pipe section 116 can be of a structure such as. B. a roughening, corrugation, ribbing and the like, or be provided with a suitable adhesion-promoting plastic in order to improve the adhesion of a material to be introduced into the inner part of the tube piece 116, but also to improve its tightness. These measures are analogous to the measures which according to the invention are expediently also provided in the area 20 between the tube part 14 and the plate 12. The above materials are generally referred to below as adhesive bridges, which, however, are only used for their intended purpose.

Using a molded part, a grout 128 is poured into the space between the pipe section 116 and a molded part, not shown here. The molded part can be removed as soon as the grout has set. The molded part, not shown here, leaves a shape in the grouting mortar which adapts to the inside diameter of a line to be connected essentially without projections. The molded grout 128 usually also forms the impetus for the line 130 to be connected.

In the present case, when the grouting mortar 128 is processed, a connector 118, which preferably consists of ductile cast iron, is cast in firmly and essentially integrally to remain in the connector. A permanently elastic seal 120, which is provided between the pipe section 116 and the connection piece 118, is generally simultaneously inserted into the line connection or anchored in the grout 128.

For the tightness and the mechanical stability of the above-mentioned connections between the individual parts of the shaft, it is essential that the grout in the joint 16 or in the pipe connection is an essentially shrinkage-free, frost and salt-resistant mortar, which is particularly free of chlorides and largely oil-resistant. In addition, it should show little or no segregation.

FIG. 3 shows the cross section of a manhole or finished manhole 10 produced according to the invention, which is preferably made of fiber cement. The line connection shown here is mainly suitable for the connection of plastic and GRP pipes 136 to a shaft. 8 shows, for example, some possible profiles of pipes 140, 141, 142 which can be connected to the manhole produced by the method according to the invention. With appropriate connections, gas, telephone and electrical lines can also be connected via appropriate couplings made of plastic, stoneware or the like.

In FIG. 7, an adhesive bridge 115 is provided in a pipe section 116, which generally consists of fiber cement. The space between an adapter pipe section 134 and the pipe section 116 is filled with grout 128. The adapter pipe piece does not have to extend over the entire length of the pipe piece 116, but can also be partially replaced by a molded part that can be removed later during casting. The adapter tube piece 134, which is preferably made of plastic, can also protrude from the line connection into the interior of the shaft.

As a rule, the adapter pipe piece 134 should protrude from the line connection side as far as that the sleeve or the double sleeve of a plastic pipe to be connected, in particular completely overlapping, can be pushed onto the projecting part of the adapter pipe piece 134.

Between the outer surface of the adaptation pipe piece 134 and the inner surface of the pipe piece 116, a continuous elastic seal 120 can be attached on the line connection side in order to prevent the penetration of moisture in a supplementary manner.

The completed line connection can now be permanently sealed and mechanically stable in the opening 114 of the shaft or finished shaft 10 using a two-component adhesive 126. The line connection described is now ready to be connected to the connection sleeve or connection double sleeve of a plastic pipe 136, for example using additional seals.

9 shows a shaft 10 which is manufactured at the factory according to the production sequence according to the invention, a fiber cement pipe section 116 which forms the outer wall of the line connection and which is provided with an adhesive bridge 115 on its inner circumference. A molded part (not shown), which may have a groove, is inserted into the fiber cement pipe section 116. A sealing element is inserted into this groove in such a way that it projects with an anchoring part 121b into the free space between the pipe section 116 and the shaped part (not shown). If the above-mentioned free space is now filled with the grouting mortar 128, the sealing element 121 is automatically anchored in the setting grouting mortar 128 via its anchoring parts 121b. If the grout has set, the molded part (not shown) can be removed be, the sealing element 121 remains in its anchorage in the grout 128.

The appearance of the shaped element and the shape of the sealing element 121 depend on the shape of the connecting part of the concrete or reinforced concrete pipe to be connected later, or another connecting part, for. B. for gas or telephone lines.

10 shows a concrete or reinforced concrete pipe in its connection area 142 in its end position in the molded, set grout 128. The sealing function, as described above, is brought about by the seal 121 anchored in the grout 128.
