FABEKUN - Telescope Tube

FABEKUN telescope tube. It consists of two FABEKUN pipe pieces, which are displaceably connected to one another via an extended sleeve inside a plastic jacket tube. In this case, the plastic jacket tube on the sleeve side of the telescopic tube is firmly connected to the concrete of the one FABEKUN pipe piece via anchor bolts. The second FABEKUN pipe piece, on the other hand, can be displaced inside the jacket tube. The intermediate space, which was created between the concrete pipes through the extended sleeve, can be filled with air or water via a valve on the jacket pipe and thus build up a pressure. Due to the overpressure in the interior of the intermediate space, the movable part of the telescopic tube now shifts and in this way closes the gap in the damaged posture. A circumferential seal between the jacket tube and the movable FABEKUN pipe piece prevents the compressed air or water from escaping during the application.

The functionality is very simple: First, the damaged part of the defective posture is removed in order to be able to use the FABEKUN telescope tube. In the next work step, the pressure is applied. It ensures that the sleeve and tip of the telescopic tube connect precisely and tightly to the position.
