Description

The invention relates to a large container consisting of a base plate and on this or on a wall surrounding this foundation walls of prefabricated reinforced concrete circular segment elements, wherein the circular segment elements have at their mutually facing end faces of seals surrounding longitudinal grooves for receiving Injektionsfüllgut and between the end faces have at least one circumferential strands surrounding of cladding tubes, wherein one of the circular segment elements is designed as a guy element, in which the cladding tubes and the tensioning strand receiving them are guided crosswise to the outside. The invention further relates to a method for producing a corresponding large container.

The DE 33 35 141 A1 discloses such a container. When constructing such containers, at least one tube is regularly inserted into the joints between two adjacent circular segment elements, via which injection filling material is injected into the longitudinal groove. In order to achieve a good and uniform filling of the longitudinal groove, a corresponding injection port is provided regularly for each longitudinal groove.

But it has also become known that z. B. only every second joint is provided with corresponding injection ports, and that there is a distribution of Injektionsfüllguts on the cladding tubes.

The disadvantage, however, is that in the region of the guy element, the jacket tubes are guided crosswise outwards for the purpose of introducing the tensioning cable. Thereby is in the injection of Injektionsfüllgut z. B. in a groove of the guy element replacement of Injektionsfüllgutes to the other side of the guy element not possible. Therefore, in order to ensure a complete injection of all joints, at least several injection ports would have to be provided.

The invention has for its object to show a large container and a method for producing a large container in which a single injection port cost, a complete, safe and satisfactory filling of all joints is achieved.

To solve the problem it is proposed that the guy element has at least one casting tube in addition to the sheaths for the tensioning cable, which connects the two end faces of the guy element in the region of its groove.

By Vergusshüllrohr ensures that even in the region of the guy element a uniform distribution of Injektionsfüllguts can be made from groove to groove. An interruption of the flow of Injektionsfüllgutes by the crosswise outwardly placed ducts is excluded.

This allows the injection of a container from one place. Unlike before, even the injection can be placed directly next to the guy element. It is advantageous that the joints are thereby filled much faster and more uniform and results in a much higher tightness guarantee. Likewise, air pockets are avoided.

It is advantageous that the diameters of the cladding tubes receiving the clamping wire exceed the diameter of the tensioning wire in such a way, and that the diameter of the casting tube of the anchoring element is dimensioned such that a horizontal Compensation of Injektionsfüllgut on the ducts and / or grouting ducts from joint to joint is possible.

Instead of the filling of the joints on the ducts in addition to the clamping strands receiving cladding, as well as the guy element, additional Vergusshüllrohre can be provided in the circular segment elements to allow optimal uniform distribution of Injektionsfüllgutes.

For the production of a large container according to the invention is proposed as a way to set the circle segment elements on a foundation, at least pretension with the tension strands and then pour a bottom plate, the upstanding circular segment elements serve as a formwork for the bottom plate. But it is also possible, for. B. prefabricated to provide segmented reinforced concrete floor slabs on which the circular segment elements are placed.

One of the joints between the circular segment elements may have an injection port, via which injection filling material is filled from below into the groove of the first joint. About the cladding and / or Vergußhüllrohre the Injektionsfüllgut can flow from one to the next groove on both sides of the first filled groove. As a result, a fast filling of all grooves is achieved. By filling from bottom to top, air pockets are avoided.

FIG. 1 shows a large container 1, which consists of eight prefabricated reinforced concrete circular segment elements 2, wherein one of the eight circular segment elements is designed as guy element 3. Between the circle segment elements 2 but also the circle segment elements 2 and the guy element 3 joints 4 are formed. Each fugue is sealed at its outer edge. Between the sealing surfaces 5, the circular segment elements 2 and the guy element 3 grooves 6, which together give a space in which Injektionsfüllgut can be filled.

FIG. 2 shows the guy 3 with the sealing surfaces 5 and the groove 6, 6 '. The section in the guy 3 is placed so that the cross-over cladding tubes 7 and 8 in the cladding tubes are visible.

FIG. 3 shows the guy element 3 in a cutting height, in which the Vergußhüllrohr 9 can be seen. The Vergusshüllrohr 9 is solely for the transport and compensation of Injektionsfüllgutes.
