Definitions

  • the invention relates to a sealing profile strip made of elastic material for the sealing of tunnel vaults, with a cross-section essentially forming a hexagon, which has two long sides, one of which for resting the profile bar in a recess of a tunnel vault element and the other for contact with an identical long side a further, identical profile strip is determined in an adjacent tunnel vault element, with a plurality of grooves 8 open towards the latter and a series of channels horizontally offset to these grooves being arranged along the first longitudinal side.
  • tubbings are often used for lining tunnel vaults, rectangular or square plates made of concrete, which are mainly arranged on the vault apex. In its narrow sides there are depressions in which sealing profile strips are embedded, which come to lie on one another under pressure. Its purpose is to prevent water from entering the tunnel. To achieve this, the profile strips must meet certain requirements and are therefore trained accordingly.
  • the cross section of such profile strips forms a narrow hexagon, two of the six sides being considerably longer than the others. With one side of each profile bar lies on the bottom of the recess of the tubbing, with the other it lies against the corresponding side of the opposite profile bar.
  • the cross section shows several grooves on the first long side mentioned, which are open towards this, as well as several closed, mostly in cross section circular channels, as can be seen, for example, from GB-A-2 210 117. However, these channels are not always present, as EP-A-0 306 581 shows; only the grooves are made there.
  • the water pressure can work particularly well, especially for the profile bar that has been partially exposed by the offset.
  • the contact pressure is constant over the remaining part of the long sides due to the lack of channels in the profile strips according to EP-A-0 306 581, a slight weak point or defect in one of the sides, which originates from the manufacture, is sufficient to prevent this Allow water to penetrate there, after which time it can separate the two contact points.
  • the ends of the contact sides must be designed in such a way that there is a particularly high pressure on the opposite contact side. This then decreases with the offset, but is still large enough to avoid separating the contact sides.
  • GB-A-2 210 117 shows such a configuration of the contact sides.
  • the two contact surfaces are concave, so that only the ends mentioned lie on one another.
  • these ends lie on special projections which protrude from the adjacent oblique side of the hexagon. On however, this affects the water pressure over its entire round surface, so that the contact pressure is negatively affected.
  • the other embodiment is better, in which the corner regions of the profile cross section support the ends mentioned.
  • sticking to a circular cross section of the channels prevents optimal material concentration. With circular channels, the material cross-section varies from one place to another and can therefore not be influenced in the desired way.
  • the sealing profile strip according to the invention avoids these disadvantages. It ensures that the ends mentioned are optimally supported by a suitable material cross-section at those points. However, it also takes account of the offset, in that in such a case the section of the contact side lying between the ends is also supported by suitable material cross sections in order to maintain a perfect seal there with one end of the opposite contact side. All of this requires a departure from the traditional circular cross-section of the channels, which, moreover, is necessary in order to be able to absorb the elastic deformation of the profile strips during and after assembly.
  • Such a sealing profile strip is characterized according to the invention by the features of claim 1.
  • the upper end of the profile strip in the figure is thus the one on which the pressure of the water present in the rock or soil acts and whose penetration into the tunnel must be prevented, while the lower end is directed towards the tunnel bore and is consequently not exposed to any water pressure , a fact that still has to be considered.
  • a further profile strip 3 'in a segment 1' is shown in dashed lines, which is arranged in mirror image to the first; for reasons of clarity, however, it is drawn at a certain distance from it, which is not the case, since the two profiled strips must lie against one another under pressure in order to be able to seal.
  • their opposite sides are deformed and compressed in the corners, as will be explained later.
  • the usual cross-sectional shape of such sealing profile strips used for tunnel construction is, as can be seen, approximately a hexagon, two sides, namely sides 4 and 5, being substantially longer than the others and running parallel to one another.
  • the side 4 lies in the recess 2, while the opposite side 5 serves to interact with the corresponding side 5 'of the opposite profile strip by mutual contact. It should therefore be referred to below as the contact page.
  • a side 6 or 7 adjoins the side 5 at each end.
  • portal-like grooves 8 are arranged in the cross section of the profile strip. They all have the same shape and size and are open towards side 4. Viewed from the side 4 or from the recess 2, there is a series of closed cavities or channels 9, 10 above these grooves 8.
  • the outer channels 9 have a kind of trapezoidal shape, but the smaller of the two parallel sides is replaced by an arc piece 91 of a small radius and the larger side, the base, by an arc piece 92 of a larger radius than that of the arc piece 91.
  • the two straight sections 93, 94 converge towards the contact side 5; these sections are preferably rectilinear.
  • the adjacent channels 10 have arisen from a circular shape, but part of this circumference has been replaced by a straight section 101.
  • This section together with the section 94 of the adjacent outer channel 9 adjacent to it, to which it runs at an angle, forms a wedge-shaped widening upwards and mainly delimited by the contact side 5, i.e. a part of the total cross section in which the material the sealing profile strip is particularly concentrated, and which therefore also has a relatively high compressive strength or deformation rigidity. Such a part is present at each end, as can be seen from the figure.
  • each outer channel 9 which delimits the outside thereof, also forms the delimitation of a corner region 13, which is further defined by the side 6 or 7 and an extension 12 of the contact side 5 Page 6 or 7 and the corresponding section 93 parallel to each other, which means at the same time that the latter must be straight in this case. Due to the parallelism of the two limitations mentioned, the wall thickness of the corner region 13 remains constant in this section, which contributes to its strength. This strength against the action of pressure when the two profile strips 3, 3 'lie one on top of the other is further increased by the extensions 12 already mentioned at the two ends of the rectilinear contact sides 5.
  • each of the extensions 12 extends at a slight angle to the contact side 5 such that, if one looks at the entire cross section from the side 4, they can be described as rising outwards.
  • a corner 14 is formed which protrudes the furthest with respect to the entire cross section of the profiled strip 3 and at the same time slightly enlarges the corner region 13. Since the opposite profile strip 3 'of course has the same corners, they touch first when installing the segments 1, 1', and the corner regions 13 are thereby compressed. The back pressure that arises in this way then ensures that where the two corners meet, there is sufficient tightness that prevents any ingress of water.
  • a bore 15 drawn in broken lines in the figure is therefore provided, which only has the upper outer channel 9 and the groove 8 adjacent to it, if need be also the channel 10 directly adjacent to the first-mentioned channel; connects with the side 6 of the bar and opens out there; thus only those cavities receive the full water pressure in which the surrounding material of the profile strip 3 is supported with certainty by the opposite profile strip 3 '.
  • normal air pressure still prevails in the lower cavities, which is essentially the same as the pressure in the gap below the profile strip. Pressing out the bar can thus be avoided.
  • the distances between the channels 9 and 10 are between them, i.e. the distance between the two closest points on the circumference of two adjacent channels is essentially the same everywhere. This applies not only between the channels 9 and 10, but also between the two channels 10 shown here among themselves, and would also be used if additional channels were possibly present between these channels 10.
  • a coating or sealant 16 is advantageously applied in the recess 2 before insertion.
  • This sealing compound the so-called primer, is intended to prevent water from seeping down between the tubbing and the relevant sealing profile strip.
  • this mass can be carried out as a two-component paint, i.e. an adhesive is added to it, which then securely holds the profile strip in the recess 2.
