Definitions

  • Sealing profile strip made of elastic material for sealing tunnel arches
  • the invention relates to a sealing profile strip made of elastic material for sealing tunnel vaults, with a cross-section essentially forming a hexagon, which has two longitudinal sides 4, 5, one of which 4 for resting the profile strip in a recess 2 of a tunnel vault element 1 and the other 5 is intended for contact with an identical longitudinal side 5 * of a further, identical profile strip 3 'in an adjacent tunnel arch element 1', along the first longitudinal side 4 several grooves 8 open towards it and above it a series of horizontally closed these grooves offset channels 9, 10 are arranged.
  • tubbings are often used for lining tunnel vaults, rectangular or square plates made of concrete, which are mainly arranged on the vault apex. In their narrow sides there are depressions in which sealing profile strips are embedded, which come to rest 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.
  • Each profile bar rests on one side on the bottom of the recess of the tubbing, and on the other it lies against the corresponding side of the profile bar opposite.
  • 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 that lie above the grooves and are also arranged in one or even two rows next to each other. Grooves and channels therefore run parallel to one another in the longitudinal direction of the profile strip.
  • the pressure remains uniform over the entire length of the contact side in the standard version with approximately the same intervals everywhere. However, this only applies if the two profile strips lie exactly on top of each other. However, it can happen that due to tolerances of the elements, the assembly or tunnel geometry and the pressure of the terrain surrounding the tunnel, the mountain pressure, a relative shift of the two profile strips to one another occurs over time, the so-called offset.
  • the water pressure can work particularly well there.
  • the profile strip, the contact side of which has been partially exposed due to the offset is pressed together slightly by the water pressure, since the channel lying initially is deformed somewhat under the pressure. The two contact sides are progressively driven apart by this water wedge until finally there is no contact between the contact sides.
  • a sealing profile strip which, together with its other strip which is in contact with it, should also withstand higher water pressure, must have the following properties: a) protruding projections which are as far out as possible, b) a contact or counter pressure surface , which is at least as wide as the maximum permissible relative displacement distance of the two strips (maximum permissible offset) c) a higher sealing or contact pressure, which is not reduced by the water pressure as far as possible and remains constant for a long time.
  • a sealing profile strip is characterized by the features of claim 1.
  • a tubbing 1 with its sealing profile strip 3 arranged in a recess 2 is shown in the position in which it is mounted in the tunnel vault.
  • 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 consequently no water pressure is exposed to a circumstance that still has to be considered.
  • a further profile strip 3 ' is shown in dashed lines 1 * in dashed lines, which is arranged 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 bear against one another under pressure in order to be able to seal.
  • their opposing 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 considerably 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.
  • the respective debugging is clock side 5 is strongly rounded, as shown by the dashed lines 6 1 , 7 '; it also results that those sides are more inclined than in this profile strip according to the invention.
  • 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 the side 4. Viewed from the side 4 or from the recess 2, a series of closed cavities or channels 9, 10 lies above these grooves 8. They do not lie exactly above the grooves, but offset laterally to them.
  • the outer channels 9 have a kind of conical shape, but the tip is replaced by an arc piece 91 of a small radius and 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 adjacent section 94 of the adjacent outer channel 9, to which it runs at an angle, forms a wedge-shaped material section 11 which widens upwards and is mainly delimited by the contact side 5, that is to say part of the total cross section. in which the material of 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 its outer side, 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 area 13 remains constant in this section, which contributes to its strength. This strength against the action of pressure when the two profiled strips 3, 3 * lie on top of one another is further increased by the extensions 12 already mentioned at the two ends of the straight 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 profile 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 each other when installing the segments 1, 1', and the corner regions 13 are thereby compressed. The back pressure which arises in this way then ensures that where the two corners meet, there is sufficient tightness which 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 one in the adjacent groove 8, possibly also the channel 10 directly adjacent to the first-mentioned channel with the Connects page 6 of the bar and opens into the open there; thus only those cavities receive the full water pressure at which the surrounding material of the profile strip 3 is supported with certainty by the opposite profile strip 3 '.
  • normal air pressure 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 ie 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 sealing compound 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. it is mixed with an adhesive which then securely holds the profile strip in the recess 2.

Abstract

La baguette d'étanchéité profilée présente dans sa section un certain nombre de rainures (8) de mêmes dimensions ainsi qu'une série de canaux (9, 10). Ces canaux ont cependant des sections différentes. Les canaux extérieurs (9) ont la forme d'un cône avec une pointe arrondie (91) et une extrémité incurvée (92) opposée . Les canaux intérieurs (10) ont la forme d'un cercle dont une partie de la circonférence est toutefois remplacée par une section rectiligne (101). La baguette profilée comporte également, sur son côté (5) destiné à être mis au contact d'une autre baguette identique, deux prolongements de dimensions croissantes (12) formant des angles saillants (14). Du fait de la configuration particulière de ces sections, il se forme entre les canaux (9, 10) des sections (11) particulièrement résistantes à la compression et entre les canaux extérieurs (9) et les côtés (6) de la baguette profilée qui bordent ces canaux, des régions cornières résistantes (13) qui assurent de remarquables conditions d'étanchéité aux infiltrations d'eau.
