DESCRIPTION:
BRIEF SUMMARY
The invention pertains to a method and a device for pressing injection material into the joints between concrete bodies as well as an arrangement of the device on a concrete surface of a primary concrete body.
It is known to utilize injection tubes (Swiss Patent No. 600,077) or injection channels (European Patent No. 0,418,699 A1) in systems for sealing the joints between concrete bodies.
In instances in which injection tubes are used, the tube ends of an injection tube assigned to a grouting sector (joints between concrete bodies are usually divided into grouting sectors that have a length of approximately 8 to 12 m) extend toward the outside so that the beginning of the tube and the tube end are freely accessible from the outside after completing the concrete work within the region of the joint. The concrete boarding must be provided with corresponding openings for the ends of the injection tube, so that additional labor is required with respect to the concrete boarding. The injection material is pressed into one end of the tube until it is discharged at the other end of the tube. Subsequently, the grouting of the joints is carried out by increasing the pressure. During the erection of the concrete boarding and/or the grouting process, it is sometimes difficult to prevent the ends of the tube from being damaged, so that the introduction of the injection material becomes more difficult.
In order to press the injection material into the injection channels, the aforementioned state of the art suggests aligning the abutting edges of two opposing channels at a distance from one another and placing a press-in plug connection of identical dimensions over the region of the abutting edges in a positive fashion, whereby a movable, portative and nonporous tube extends from the outside of the concrete body into the interior of the press-in plug connection such that the injection material may be pressed in.
The aforementioned state of the art pertaining to injection channels additionally suggests producing a subsequent connection with the injection channel via a bore to be arranged in the concrete wall after completing the concrete work and disassembling the concrete boarding of the secondary concrete wall instead of providing tubes that extend toward the outside.
The invention is based on the objective of creating a method and a device for pressing injection material into the joints between concrete bodies that simplifies the process of pressing injection material into the joints between concrete bodies, in particular into the joints between concrete bodies that are provided with injection tubes and/or injection channels. In addition, an arrangement of this device on a concrete surface of a primary concrete body should be created that insures a simple and safe grouting of the joints between concrete bodies.
The hollow target body provided according to the invention is connected with the tubular injection body, e.g., an injection channel, which forms the subsequent injection path in such a way that the injection material introduced into the hollow target body is conveyed into the tubular body. This conveyance of the injection material into the tubular body may, for example, be realized by the fact that the tubular body protrudes with its open end into the hollow target body. Alternatively, two tubular bodies may protrude with their open ends into the hollow target body and be arranged therein at a distance from one another, so that the injection material may be conveyed from the target body into the tubular body via the open ends of said tubular body.
One essential aspect of the invention consists of the fact that the target body provides a relatively large target surface that serves as a perfect location for a bore that may be drilled into the concrete wall containing the hollow target body from the outside. For this, it suffices to mark the approximate location of the target body on the primary concrete wall before the secondary concrete wall is arranged over the tubular body and the hollow target body connected wi
