By means of the buckling mechanism (20), at least one support structure element (12, 16, 19) can be placed into a buckled position. Furthermore, an actuating device (30) is provided which is designed such that the buckling mechanism (20) can be placed into a buckling enable position and a buckling blocking position by means of the actuating device (30).

Abstract: A means for the rehabilitation of a connecting portion between a main pipeline and a branch pipeline with a main pipe section and a branch pipe section, wherein the main pipe section has a connecting region, wherein the branch pipe section is connected at its first end portion to the connecting region of the main pipe section, wherein the branch pipe section is closed at its second end portion and wherein at least one contactless sensor is disposed within the means.

Abstract: A lining element for repairing a connection area between a main pipe and a branch pipe, comprising a layer of resin-absorbing material, wherein at least three flexible, expandable lining parts are connected to each other by at least three connections to form the lining element. Each lining part comprises a main pipe section and a branch pipe section, and side edges. The lining element is characterized in that the lining parts are connected to each other by connecting both side edges of the adjacent branch pipe sections and side edges of adjacent main pipe sections in a continuous fashion.

Abstract: A means for the rehabilitation of a connecting portion between a main pipe-line and a branch pipeline with a main pipe section and a branch pipe section, wherein the main pipe section has a connecting region, wherein the branch pipe section is connected at its first end portion to the connecting region of the main pipe section, wherein the branch pipe section is closed at its second end portion and wherein at least one contactless sensor is disposed within the means.

Abstract: A calibration hose (10) for use in a device for rehabilitating pipelines (14, 16), having a main pipe calibration hose (18) and a lateral pipe calibration hose (20), the main pipe calibration hose (18) having a connecting region (90), the lateral pipe calibration hose (20) being connected in its first end region (26) to the connecting region (90) of the main pipe calibration hose (18), and the lateral pipe calibration hose (20) being closed in its second end region (28). In order to permit the air to escape via the calibration hose, the invention proposes that a valve (30) be provided in the second end region (28).

Abstract: A device and method for rehabilitating pipe connections is disclosed that simplifies the reliable transportation and positioning of a pipe lining relative to a junction region of a building service line to be lined. The device and method provides for rehabilitating the junction of a building connection from a main pipeline into the building service line. With a positioning device, a curable pipe lining may be positioned at the junction of the building service line and the main line and, with a transport device, the positioning device and the pipe lining may be transported to the junction. A detecting device may detect an extended position of the positioning device. The detecting device may include a winding box with a switch that is actuated when a cord has been pulled out of the winding box and which triggers a signaling device.

Abstract: A method and an apparatus impregnate a lining module for repairing a pipe. An end area of the lining module provided with a resin-absorbing layer and an air-tight, outer coating, is introduced into an air-tight sleeve, and an auxiliary introduction device is fixed at an introduction area of the lining module. The transitions between the lining module and the sleeve and between the introduction area and the auxiliary introduction device are closed off in an air-tight manner by at least one sealing device. The auxiliary introduction device is closed off with respect to the ambient by a releasable blocking device in an air-tight manner in such a way that the chamber, formed by the sleeve and the auxiliary introduction device and optionally also the lining module, is closed in an air-tight manner and an introduction chamber accessible from the outside is provided for filling with resin.
