Description

1 SEALING PROFILE FOR TUNNEL SEGMENTS This invention relates to a sealing
profile to be carried in a recess (hereinafter called a "segment groove") extending around the periphery of a tunnel segment to provide a seal when such tunnel segments are assembled into a tubular tunnel, the profile having a base containing grooves running in parallel in the longitudinal direction and channels running in the longitudinal direction which are arranged in a number of rows and offset from one another from row to row.
The tunnel segments may be of concrete, cast iron, steel or reinforced concrete, and sealing profiles for such tunnel segments are known in various forms which may be divided into three groups Group I The sealing profiles have grooves only (DE-U 72 03 419, DE-U-72 29 665, D-E-U-74 32 945, DE-C-25 13 365) Group II The sealing profiles have grooves and a single-row arrangement of the channels (DE-C 28 33 345, GB-B-2 170 561, GB-B2 178 114, GB A-2 194 005, GB-A-2 193 541).
Group III The sealing profiles have grooves and a two row system of the channels. In this connection only two profiles have hitherto been known.
In the GB-A-2 017 194 a sealing profile is described in which between the two grooves which are arranged at the sides there are two channels and having above them three further channels offset with respect thereto. Sealing profiles with grooves arranged at the sides have a poor sealing action.
From GB-A-2 182 987 a sealing profile is known which has three grooves in its base. Above the grooves, in two rows, are arranged four and three channels respectively. A sealing profile of this type of construction is distinguished not only by a high sealing capacity but may also be employed in a versatile manner as regards differences in dimensioning (depth and width of the recess, distance of the segments from one another in the unloaded and also in the loaded state).
The usual istance apart of the segments amounts in the unloaded state to 8 to 15 mm (GB-A-2 182 987). But for building tunnels from very simple tunnel segments and in particular in following curves with parallel rings instead of taper rings, relatively large gap widths (20 mm and more) occur at average depths of up to 40 m (4 bar). In addition the maximum closing force amounts to e- 40 kN/m. The sealing profiles of Groups I to III are only usable now for this to an extremely limited extent.
It is an object of the present invention to provide a sealing profile which meets such requirements.
According to the present invention a sealing profile to be carried in a segment grobve extending around the periphery of a tunnel segment to provide a seal when such tunnel segments are assembled into a tubular tunnel has a base containing grooves (total number n) running in parallel in the longitudinal direction and channels (total number m) running in the longitudinal direction which are arranged in a number of rows and offset from one another from row to row in which the profile m = 3 n (n >, 4) channels, the channels being arranged in three rows, ie, from the side next the groove towards the back of the profile according to the following structural principle:
51, 3 - 1 1 1 channel row A (m A = n + 1) channel row B (m B = n) channel row C (mc = n Preferably the profile has a maximum of six grooves. The channels viewed in cross-section may be essentially of circular and/or oval and/or semicircular shape. In the latter case the part of semicircular (or arcuate) shape is adjacent the back of the profile.
The back of the profile may be made plane or concave and in one arrangement the back of the profile has two lips at the sides.
The invention may be performed in various ways and one specific embodiment together with a modification thereof will now be described by way of example with reference to the accompanying drawings in which:
Figure 1 is a cross-section through a profile according to the present invention and Figure 2 is a similar view of a slightly modified construction.
According to Figure 1 a joint 1 (longitudinal or crossjoint) is to be sealed between two adjoining segments 2 and 3 with a gap width of about 20 mm (unloaded state). For this purpose the sealing profiles 6 and 7 of rubber or rubberlike material are inserted in recesses 4 and 5. Each sealing profile has four uniform grooves 8 in its base. A total of twelve uniform channels 9 are arranged above them in three rows (A, B, C), ie, that adjacent the base having five (A) the centre channel having four (B) and the channel adjacent the back of the profile having three (C) channels. The channels preferably having within one row as well as from row to row approximately the same spacing. The back 10 of the profile is made slightly concave.
According to the arrangement shown in Figure 2 the back 11 of the sealing profile 12 and 13 is likewise made slightly concave but however has in addition lips 14 and 15 at the sides. Through this shape of the back of the profile the sealing capacity is further increased.
v In the arrangement shown the channels have been shown as circular in cross-section. However they may alternatively be of other shapes, for example circular and/or oval and and/or semicircular in shape.
