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: The invention relates to a lining element (10) for the rehabilitation of a pipeline, having a carrier layer (16) consisting of an expandable, resin-absorbent material which, in the longitudinal direction (L1, L2) of the carrier layer (16), has a first expansion rigidity, and a stiffening structure (24) which, in the longitudinal direction (L1, L2) of the carrier layer (16), has a second expansion rigidity, wherein the first expansion rigidity is lower than the second expansion rigidity and wherein the stiffening structure (24) is incorporated into the carrier layer (16).

Abstract: The invention relates to a travelling device (10, 130) for an apparatus for rehabilitating pipelines, with an adjustable undercarriage (20, 140), comprising a plurality of wheels (42, 44; 162, 164), and with a support device (30, 150) to which the undercarriage (20, 140) is fastened. A plurality of wheel sets (40, 160) are provided and each wheel set (40, 160) comprises at least two wheels (42, 44; 162, 164), wherein the wheels (42, 44; 162, 164) of a wheel set (40, 160) are rotatably mounted on a wheel holding element (50, 170).

Abstract: The invention relates to an apparatus (10) for the rehabilitation of pipelines using a fluid line system (28) with at least one fluid line (54, 56) for supplying and/or removing a fluid medium, wherein the fluid line system (28) is provided with at least one pivot joint (30).

Abstract: A lining element for the rehabilitation of a pipeline, the lining element having a substrate layer including a resin-absorbing material and a coating system, the coating system including a fluid-tight barrier layer system formed from several layers.

Abstract: The invention relates to a device for rehabilitating pipelines, having a support structure (10) to which functional units of the device can be fastened, wherein the support structure (10) has at least two support structure elements (12, 16, 19) which reconnected to one another via at least one buckling mechanism (20). 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 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: The invention relates to a lining element (10) for the repair of a connection area between a main pipe and a branch pipe, comprising a layer of resin-absorbing material. In a first variant, at least three flexible, expandable lining parts (20) are connected to each other by at least three connections (28) to form the lining element. To manufacture such a lining element, the at least three flexible, expandable lining parts are provided and connected to each other by means of at least three connections to form the lining element. Furthermore, the invention relates to another lining element (100), comprising at least one lining part (102) having a layer of resin-absorbing material, which has a tubular preform, and which is deformable by means of heat and/or forming to achieve a tubular final form.

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.
