Abstract: A sealing arrangement includes face walls of two construction parts made of concrete, reinforced concrete or the like, these face walls being pressed against each other, particularly of tunnel tube segments, as well as a strand shaped seal made of elastomeric material for sealing the gap between the construction parts or tunnel tube segments, whereby the seal has a base part which, in relation to the sealing part, is widened on both sides, forming flanges, and which, by means of these flanges and suitable additional anchoring parts, is fastened on one of the two face walls of the construction parts or tunnel tube segments, whereas the sealing part, the latter being joined with the base part in one piece, has a trapezoidal shape, viewed cross-sectionally, and, in relation to the base part, a decreasing width, with lateral flanks tapering off at the same time, and seals the gap when the construction parts or tunnel tube segments are pressed together.

Abstract: The invention relates to a seal between a side face of a first part (11) and an application face (10), the seal being made of a compressible profiled lining (1) and being comprised of an internal portion (2) sealingly fixed to the first part (11) and an external portion (3) bearing on the application face (10). According to the invention, in its original condition prior to setting the seal on the first part (11), the external portion (3) of the liner (1) is provided with at least one profile tongue (4) housed inside at least one longitudinal groove (5) provided in said external portion (3) and opening on the side of the application face (10), said tongue (4) being fixed to the internal face (50) of said groove (5) in an easily detachable way so as to be able to suppress and eventually replace the tongue (4) at least on a portion of the length of the liner (1) in order to vary the compressibility degree of the liner on the corresponding length.

Abstract: The invention relates to a seal arrangement consisting of two abutting structures of concrete, steel, reinforced concrete, cast iron or other materials and a sealing section of elastomeric material which bridges and seals the gap between the two structures, in which the structures are especially segments assembled to form a tubular tunnel with the formation of transverse and longitudinal seams, where each segment preferably has at least one peripheral recess covering all the mating sides of the segments and there is in each recess a stranded sealing section which especially has strand-shaped grooves on the base side of the sealing section and/or strand-shaped channels, forming a sealing frame with corners, and the back of the sealing section has at least one strand-shaped groove to accept an emergency seal.

Abstract: Device consisting of an inner mold (15), an outer mold and at least one injection aperture arranged in the outer mold; for the manufacture of the corners of sealing frames, in particular tunnel sealing frames consisting in most cases of four assembled strand-shaped sealing profiles made of elastomeric material, whereby each sealing profile has open and/or closed grooves extending in the longitudinal direction and arranged on the profile base side, as well as additional ducts also extending in the longitudinal direction and disposed between the grooves and the profile back surface; whereby the manufacture of the corners of the sealing frames takes place according to the injection molding process.

Abstract: A profiled seal for use in tunnel segments and comprising cut out grooves along the bottom of the seal; channels along the upper part of the seal; lateral faces and spreading feet for the seal; plus a bridge system having an outer bridge and an inner bridge.

Abstract: A sealing profile formed of rubber or rubber-like material is provided for sealing tunnel segments which have circumferential recesses. There is a plurality of slotted grooves running parallel in the lengthwise direction on the base side of the profile and a plurality of channels running parallel in the lengthwise direction, the number of channels being no greater than the number of slotted grooves and at least one channel being in alignment with a corresponding groove.

Abstract: There is provided a sealing profile formed of rubber or rubber-like material for tunnel segments having a recess therefor extending therearound, the profile having a base side facing the segment and a back side facing away from the segment, a plurality of longitudinally extending parallel flutes in the base side, lateral flanks extending angularly from the base side, a plurality of longitudinally extending parallel ducts, and at least one centrally disposed bridge through extending from the base side to the back side without impairment in its supporting effort by a longitudinal duct.
