Sealing profile for segments of tunnel tubes

You invention bäzieai

according to the preamble of claim 1.

Such sealing profiles are known (DE-PS 28 33 DE-GM 85 02 036, DE-GM 85 21 068) and have signed up for tunnel construction with the use of segments (tubbings) made of concrete, cast iron or steel has proven its worth. The essential Requirements for such a profile are:

1) favorable force-displacement behavior when compressing of the segments

2) secure bonding within the groove of the segments

3) the largest possible contact surfaces

4) Resistance to swelling, weathering and chemicals

Depending on the depth and width of the groove and depending on the distance of the segments in the unloaded or »loaded state as well as the profile thickness, special requirements are placed on the force-displacement behavior of the profile posed. The dimensions (A) have been common up to now.

Verden now called for other dimensions (B), with the Groove width smaller, the profile thickness and the distance between the segments in the unloaded or in the loaded state is greater than at (A), then with regard to the changed force-displacement behavior, there is a further development of previously known profiles inevitable.

The object of the invention is therefore to provide a sealing profile for segments of tunnel tubes to develop, which regardless of the dimensioning, a favorable force-displacement behavior having when the segments are pressed together.

The object is achieved according to the invention in that the Channels are arranged in several rows and within a row and from row to row are almost the same distance own.

A two-row arrangement of the channels is particularly advantageous, with those facing the profile back Channels are at the same height as the hill grooves.

Further expedient embodiments of the invention

■ Bind mentioned in the subclaims.

The invention is now in connection with an illustration for example described. The fig. Represents a cross-section through two segments in which Grooves according to the invention, annular sealing profiles are arranged in the not yet compressed state.

j The two segments 1 and 2 each have a groove 3

'.' or 4. There are two back to back in these grooves

! ' Sealing profiles 5 and 6 glued in. Each of these

Sealing profile has three groove grooves 7i 8, and 9 au)? On the base side. Furthermore, the profile has seven channels 10 to 16 _v which are arranged in two rows

; are »Bi inhibitions and channels have almost one another

; the same distance, creating a nearly uniform

Wall thickness is achieved. The lateral flanks 17

jj and 18 have an angle of 15 °. The surface

the side planks 19 and 20 are slightly concave in the unloaded state. The width of the flat back surface of the profile is 70 to 80 %

its maximum profile width.

If the two profiles 5 and 6 are connected by screwing segments 1 and 2 in area 21

% sanna-pressed, the rubber mass is shifted to

the grooves 3 and k into it. In the final state, the distance between the edges 22 and 23 of the segments 1 and 2 is 0 to 10 mm, depending on the structural tolerance.

The rubber compound lying above the Nat 3 or k is now largely uniformly shaped in such a way that no peak loads occur in the rubber compound. The contact pressure between the backs of the two profiles 5 and 6 is largely uniform.
