A sealing device for sealing a space established by connecting two sealing surfaces (42b, 52b) positioned on one element each of two elements (44b, 48b), for example two concrete pipes, to a position in which the sealing surfaces face each other comprises a sealing body (80) consisting of elastic material. The sealing body (80) is adapted at the connection of the sealing surfaces (42b, 52b) to take a position in the space in which it engages the sealing surfaces. The sealing device comprises an activating device (82-90) for forcing the sealing body (80) positioned in the space against the sealing surfaces (42b, 52b) when the activating device is activated. (FIG. 6a)

Sealing device

A seal for concrete pipes wherein the sealing function can be controlled by varying the relative change of length under compression, the hardness of the elastomeric material or a combination of the two. The elastomeric body is of wedge-shaped cross section wherein the wedge-shaped end is positioned at the front in the direction of introduction of the pipe end. The elastomeric body further includes a base end having an introduction opening to a reception space. An attachment portion is anchored in the reception space of the elastomeric body and is adapted to control the degree of compression of the elastomeric body.

Seal between two elements, especially between concrete pipes

A sealing device for a sealing space defined by sealing surfaces of two elements (2, 6), preferably pipes or well rings consisting of concrete, comprises a sealing element (28). The sealing element is adapted to seal a section of the sealing space extending transversely of the jointing direction of the two elements and has prior to the jointing of the elements a substantially C-shaped cross section.
