  • a tubbing which has a fire protection layer on the inside.
  • the fire protection layer is applied during the production of the body of concrete.
  • the base body consists of reinforced concrete or steel fiber concrete.
  • the fire protection layer is connected to the body via connecting or anchoring elements, such as rib projections or rods.
  • the fire protection layer is placed in a shell mold and the concrete body is made by subsequent casting of the concrete in the shell mold on the fire protection layer.
  • an insulating molding in the form of a plate, a cassette or a panel which has an insulating core of foam, which is foamed to a cover layer.
  • the top layer is made of a dimensionally stable layer of sand, pebbles, or the like Granular materials formed whose layer thickness is a multiple of the grain diameter of the granular material, during foaming of the insulating core, the foam enters the particle interstices of the granular material and connects the granules firmly together.
  • the present invention seeks to provide a Betontübbing with an inside, so the tunnel facing side, plastic layer, which is inextricably linked by a homogeneous surface anchoring with the concrete layer without further additives or manifestations, the preparation of particularly simple way should be feasible inexpensively.
  • the invention solves the problem by designing the Betontübbings according to the specified in claim 1 technical teaching, which Betontübbing in a Betienengmentg screenform can be produced inexpensively according to the manufacturing method specified in claim 11 itself at the processing site of the tubbing.
  • These fabric mats have apertures so that the plastic can partially bond to the outer surfaces of the granules while the exposed ends connect to the concrete.
  • granules or granular mats and open-pored mats made of plastic or metal for example, two-ply expanded metal, or fibers of the specified materials with a three-dimensional structure can be used.
  • fabrics which have meshes which set up on contact with liquid plastic and thus form a three-dimensional structure can be used.
  • the use of such tailored mats also provides a laminar connection to the concrete.
  • the granules used can consist of very different materials. However, these materials should not be swelling due to moisture absorption. Basalt litter, granite stone, gravel litter, plastic or metal granules, as well as plastic and metal injection molded parts have proven to be particularly suitable, which have a certain number of anchoring pins or hollow chamber parts are, for. B. angular or round pipe sections, which are partially interspersed with a plastic adhesive or a plastic compound of the plastic layer and / or enclosed, while the other opening areas are filled by the liquid concrete.
  • plastic layer z. B consist of a 1 mm or 2 mm thick cut film and the adhesive layers are about 3 mm thick.
  • the plastic layer is a polyurethane layer and the granules layer is applied in the liquid state, so that the granules are able to sink into the liquid plastic and held by the form and surface bond.
  • the granules are thus partially embedded in the plastic.
  • the concrete layer is applied. This is advantageously done in the same mold having side wall formworks.
  • the inliner body can also be prefabricated. It is expedient, however, in one pass, both the plastic layer, the granular layer and the concrete layer, taking into account the curing of the Plastic and the setting time of the concrete to bring.
  • the segments provided with inliners are mainly used in sewage and fresh water applications but also for gas pipelines.
  • the construction of the segments is usually done immediately behind the tunneling machine by known Segmentsetzmaschinen.
  • the introduced plastic layer has raised edges at the edges, onto which a sealing profile with a U-shaped slot receptacle is placed before casting the mold with concrete.
  • the profile presses with its elastic part against a sealing profile on the next tubbing or against the concrete layer, whereby the desired seal is given.
  • a sealing profile made of an elastic material can be attached with a corresponding lower, inside edge formation of the mold.
  • This can for example be previously inserted into a groove and has approaches that extend anchoring into the plastic layer.
  • a sealing profile can also be glued subsequently.
  • the sealing profile is formed from the plastic layer itself.
  • a corresponding deformation profile must be embedded in the edge zone of the mold in the side walls, which is encircled by the plastic or into which the plastic flows. In this way, for example, directly a Nutfederthetic between corresponding adjacent sides of two segments are made.
  • such a profile can also be placed on an upstand in the edge region of the plastic layer.
  • this frame wall can likewise be designed such that a sealing profile made of elastic material can be placed, pressed in or anchored therein. It can also be formed upstands, on which a sealing profile with a U-shaped receptacle can be placed. This upstand should preferably be provided in a U-shaped receptacle, so that an identical design of adjacent segments is possible. But it can also be pressed or formed a groove-shaped receptacle into which the sealing profile made of elastic material can be used.
  • a latching connection can be achieved at least on one side of adjacent segments, while the other part of the sealing profile when joining the two segments only engages in a groove of the adjacent tubbing.
  • a profiling can be provided for connection. If such profiles are not provided, then the sealing profile is glued into a groove only so that it can engage sealingly in the groove in the adjacent frame wall of the adjacent tubbing when joining the segments. In the production of the frame wall, such a sealing profile can be provided with anchoring elements, but also fastened at the same time.
  • the segments may also have openings for receiving a sleeve or a dowel.
  • other fasteners can be introduced in order to fasten, for example, carrier for cables can. These fasteners are thus fixed to the surface.
  • carbon and / or glass fibers can be introduced into the plastic layer in a known manner in order to enable a higher mechanical load.
  • carbon and / or glass fibers can be introduced into the plastic layer in a known manner in order to enable a higher mechanical load.
  • reinforcing mats made of plastic or metal fabric and / or mesh can be inserted to increase the load capacity in the concrete layers. This can cause the concrete layers to be reduced in thickness, resulting in material and weight savings.
  • the introduction of the liquid plastic in the mold also allows that At the edge of a sealing profile can be formed.
  • An already created sealing profile made of elastic material can also be inserted as an edge profile in the plastic layer. If a molding of a sealing profile, so it is advisable to form at two angles to each other arranged sides of the tubing sealing lips as springs, the corresponding attachment sides of the next tubbing have contour-matched sealing profiles.
  • a tongue-and-groove connection is created, which is self-sealing.
  • the Anformung lends itself to because the plastic layer is entered in liquid form into the mold and thereby also Randausformungen be possible by trailing. However, the formwork walls must then be movably mounted so that they can be moved apart for the shaping of the tubbing.
  • the shape itself can be made in several parts, in order to produce several segments simultaneously. But it can also be made in one piece.
  • the polyurethane layer can be poured in or else sprayed in, for which purpose a spray head distributes the liquid plastic over the surface. The liquid plastic is kept at temperature throughout the overreach until it emerges from the spray head. After application or during the application of the plastic layer, the granules can already be sprinkled in the region which has the desired plastic layer thickness. This can also be done by a distribution head, which scatters the granules at a lower speed or with a time delay on the plastic layer. But it is also possible by separate pipes with exit slot the granules Spread evenly across the width.
  • the granules fall with the lower sections in the still liquid plastic material. This encloses cavities, undercuts, in short, all the surface parts of the granules that sink into the plastic. The granules are firmly bound. Will now after a curing time of z. B. four minutes applied the plastic layer, the liquid concrete surrounds the protruding from the plastic mass granule surface sections and adheres to the surfaces. Again, granule parts are engaged behind or filled cavities, so that a surface anchoring of the entire plastic inliner is given. In the liquid plastic mass along the frame wall, a sealing profile made of an elastic plastic or rubber-like material can be inserted, which allows a side seal when joining the segments.
  • FIG. 1 shows a plastic view 1, which is introduced into a box-shaped form by means of a spray head. It is a consisting of components A and B polyurethane layer. The mold also has a pin, so that the opening 4 is already exposed during spraying. In this breakthrough 4, for example, a dowel can be used to attach it to fasteners can.
  • a granular layer 3 is applied in the liquid state of the plastic, the FIG. 2 is apparent. It is a basalt layer, so that parts of the basalt are embedded in the plastic and fixed therein, while the other sections protrude.
  • On the cured plastic concrete layer 2 is applied in the same form.
  • the liquid concrete combines with the basalt stones of the basalt layer, so that there is a surface-shaped anchoring, which extends in the third dimension, over the adhesion surfaces on the basalt stones. After the setting time of the concrete, the finished tubbing can be removed from the mold.
  • FIG. 3 shows a sealing profile, which consists of a groove 5 and a next tubbing from a bead-shaped spring 6. These are automatically formed in the mold.
  • the side shells of the form are movable and have the corresponding negative embodiments of each two abutting Pages on, so that in the composite tubules on the insides are completely insulated.
  • Fig. 4 shows in the form of a section of a tubbing an embodiment in which in a frame wall 7 on the base layer, the plastic layer is shown pulled up, into which by corresponding rib arrangement on the inside of the mold, a groove 8 is formed.
  • the inside of the frame wall 7 has the granules of the invention or a three-dimensional mat to produce the desired bond to the subsequently poured concrete layer 2.
  • This groove 8 may be provided circumferentially in the frame walls 7, so that all segments are structurally executable.
  • the sealing profile 9 which may for example consist of different plastics or rubber compounds, adhered to the bottom side.
  • An adhesive bond may also be provided in a connection with the adjacent tubbing in the corresponding groove. But it is sufficient a frictional connection to ensure the desired seal.
  • Fig. 5 is a section of a tubing shown, which shows that when the sealing profile 9 is provided with anchoring elements 10, the sealing profile 9 in the manufacture of the plastic liner, so the plastic layer can be poured with the anchoring elements. Subsequent sticking or vulcanization is not required.
