Definitions
- the invention relates to a sealing arrangement for shaft and tunnel structures.
- Each body which is composed of individual monolithic components, has contact joints. This applies, for example, to shaft and tunnel structures, which consist of prefabricated parts (Tubbingen). Should e.g. a tunnel under the groundwater level is created and used, this results in the need for waterproofness of the entire structure. For a building of a variety of prefabricated items arises from this not only the demand for the water resistance of the monolithic components, but also after the sealing of the contact joints between the components against the hydrostatic pressure.
- Sealing arrangements for sealing structural joints in tunnel structures which are produced from prefabricated components (Tubbingen), are known in principle, see for example DE 102005039253, DE 102005039056, US 4946309, EP 0222968, EP 0441250 and EP 0995013.
- a sealing element in Glued in a groove which runs at a constant distance from the outer surface of the tubbing around the butt sides.
- the sealing effect of the sealing system is achieved by joining the tubbing in that the sealing elements in the joints touch each other mirror-symmetrically.
- the contact must be made at least with a surface pressure that is above the Pressure in the upcoming print medium is.
- the desired surface pressure is set by the choice of the elastic compression behavior of the two sealing elements in dependence on the way of the compression.
- the known sealing arrangements have numerous disadvantages. For example, when choosing an incompressible elastomer as the material for the sealing elements, the pressing force in the sealing arrangement can increase enormously. In extreme cases, damage to the sealing arrangement as well as to the environment can not be ruled out in the transmission of the associated reaction forces in the component. This leads in particular to the local encounter of several components with the corner bodies of their sealing systems to leaks or damage.
- the mirror-symmetrical arrangement of the sealing elements remains practically a coincidence.
- the contact of the two sealing elements then takes place only on a reduced support share. Since the surface pressure is not independent of this percentage of support, the risk of leakage increases with reduced pressure.
- the sealing elements in the contact joints of the tunnel should have an unlimited lifetime as far as possible.
- the technical requirement is defined as 100 years lifetime.
- the property of relaxation of the material must be considered.
- the relaxation of the elastic tension forces (up to 40%) over time must be taken into account by an excessive initial tension in the assembly of the sealing arrangement. All already undesired force reactions of the elastic tension forces are amplified accordingly.
- the prior art sealing arrangements only act singularly.
- a leak inevitably leads to a leakage current from surrounding medium, eg water, into the tunnel.
- the targeted localization of the leak proves to be problematic due to the wall thickness and the propagation possibilities in the contact joints of the components.
- a renovation of the leak can therefore not be performed locally on the inside of the sealing system and always requires a lot of effort. Redundant sealing systems can be realized with the means known in the art, however, only with great effort and in large tunnels.
- Object of the present invention is therefore to seal the joints between
- the invention provides a sealing arrangement for manhole and tunnel structures, comprising a) at least two components abutting one another with abutting sides, so that a joint is formed between the components, which connects a first area to a second area wherein the first region comprises a first medium having a first medium pressure and the second region comprises a second medium having a second medium pressure and a pressure difference exists between the first and second medium pressures, and b) at least one elastic sealing system to each Shock sides of the components for sealing the gap, wherein each of the sealing systems has at least one projecting to the joint sealing element, with which the sealing systems abut one another at a contact plane and wherein the Sealing elements each have at least one pressure surface which is exposed to the medium with the higher medium pressure, so that a sealing force is applied between the sealing elements on the contact plane, which is greater than the voltage applied without the pressure difference and generates a contact pressure which is greater than that Pressure difference.
- the sealing elements of the sealing system are formed in their geometry such that they have after mutual contact pressure surfaces against a low pressure or the atmosphere. Due to the pressure difference between the media, a differential pressure acts on these pressure surfaces, resulting in the force which ensures the required surface pressure on the surface with which the sealing elements lie against one another at the contact plane.
- the pressing pressure is inevitably always adapted to the respective media pressure and essentially independent of the gap width which occurs after the contact.
- significantly lower reaction forces are required in the inventive arrangement.
- the contact pressure can also be adjusted.
- an offset of the components does not change the quality of the tightness, since the contact does not depend on the symmetry of the sealing elements.
- the sealing element is pivotable about a joint or tilted.
- a "joint” is understood here as meaning a region of the sealing system which has or forms a rest pole around which the pivoting movement of the sealing element takes place and which itself does not participate in the pivoting movement, at least substantially.

- the joint region may have a reduced cross-section compared to the adjacent base body and / or sealing element and / or a softer material.
- the joint connects the main body of the sealing system with the sealing element. The pivoting or tilting movement can take place in the direction of the joint or opposite thereto.
- the force portion of the contact pressure generated by any biasing of the sealing member is greater than the force portion of the contact pressure caused by the media differential pressure, i. the pressure difference between the media is caused as low as possible.
- the force component of the contact pressure generated by the media differential pressure is> 50%, more preferably> 60%,> 70%,> 80%,> 85% or> 90, particularly preferably> 95%,> 96%,> 97% ,> 98% or> 99%.
- contact pressure or “surface pressure” is meant herein pressure at the contact surface, i. the surface at which the sealing elements are in contact at the contact plane prevails.
- a “pressure surface” is understood here as meaning any surface of the sealing system, in particular of the sealing element, which is exposed to the medium pressure.
- each of the sealing systems has a base body with which the sealing system is fastened to the component.
- the attachment can be done in many ways, for example by gluing, Einbetontechnik, pressing or with the help of anchoring feet.
- the elastic sealing system consists of elastomeric material.
- elastic refers to the property of a body or material, under the action of force, to change its shape and, in the absence of kenden force to return to its original form.
- An elastic body is to be understood here in particular as a body having a modulus of elasticity of 0.1 or below, preferably of 0.01 to 0.1.
- An example of an elastic material is silicone rubber.
- an “elastomeric material” is meant here a dimensionally stable, but elastic natural or synthetic polymer whose glass transition point is preferably below room temperature (25 ° C).

- FIG. 2 Schematic cross-sectional view of an embodiment of the inventive arrangement.
- FIG. 3 shows a detail of the cross-sectional view according to FIG. 1.
- FIG. 4 partial views of cross sections through various embodiments of the inventive arrangement.
- FIG. 6 shows a cross-sectional view of a further embodiment of the arrangement according to the invention.
- Fig. 7 shows a cross-sectional view of the embodiment of the inventive arrangement according to FIG. 6 with a minimum joint width.
- FIG. 8 to 10 are cross-sectional views of further embodiments of the arrangement according to the invention.
- Figure 1 shows schematically a section of a tunnel structure 1 of individual components 2, eg finished concrete components. Between abutting sides 3 of the components 2, joints 4 are formed, which connect the outer region 5 with the inner region 6. The joints 4 are sealed with sealing systems 7 not visible here.
- FIG. 2 schematically shows a cross-section through an embodiment of the sealing arrangement 8 according to the invention. Shown is a part of two components 2 abutting one another with their abutment sides 3.
- the abutment faces 3 of the components 2 form a joint 4 and each have a peripheral circumferential chamfer 9, in FIG each an elastic sealing system 7 is introduced.
- the elastic sealing system 7 may be glued, for example, in a recess 14 of the component 2.
- Other attachment options, such as concreting, anchoring by means of anchoring foot, etc., or combinations thereof, are of course also possible.
- the sealing systems 7, which are preferably made in one piece from an elastomeric material, are arranged mirror-symmetrically with respect to a contact plane 12 and have a main body 10 and a sealing element 11.
- the sealing element 11 is connected to the main body 10 via a hinge region or a joint 16 and can be tilted or pivoted about the joint 16, so that the sealing elements 11 decrease in the distance between the abutting sides 3, i. with a reduction in the joint width, be pivoted or tilted towards the respective chamfers 9.
- the sealing elements 11 touch each other at the contact plane 12 and bridge in this way the joint 4.
- the sealing system (7) are each attached to the base body (10) on the component (2).
- the sealing system 7 serves to seal the gap 4, whereby the sealing of two areas 5, 6 is achieved against each other, which are located on opposite sides of the sealing system 7.
- the first region 5 may be, for example, the outer region and the second region 6 the inner region of a tunnel, both during the fluid and the solid bedding of the tunnel.
- both areas 5, 6 are different or possibly also identical media 17, 18, however, have different pressures, so that between the first medium 17 in the first region 5 and the second Medium 18 in the second region 6 there is a pressure difference.
- the first medium 17 in the first region 5, ie the external medium, for example water and / or soil has a higher pressure than the second medium 18 in the second region 6, ie the internal medium, for example the atmosphere.
- the medium 17 at the higher pressure exerts a force on the pressure surfaces 15 of the sealing elements 11, so that the sealing elements 11 at the contact plane 12 produce a sealing force that is greater than the force that would be generated without the pressure difference, and generates a contact pressure , which is greater than the medium differential pressure, ie the pressure difference between the media (17, 18) (see also Fig. 3 in addition thereto).
- the sealing force is at least predominantly, possibly even completely, generated by the pressure difference, and not or at least not to a significant extent by elastic tension forces due to the compression of the elastic sealing systems 7. In this way, a contact pressure is generated, the joint width of the elastic preload is almost independent.
- FIG. 3 the principle underlying the sealing arrangement according to the invention is illustrated once more schematically using the example of the sealing arrangement shown in FIG. For clarity, only one half of the Dichtanordung 8 is shown. Arrows symbolize the forces acting on the sealing element 11 respectively. The arrows with the filled arrowheads represent forces exerted by the higher medium pressure medium 17. Arrows with open arrowheads represent the forces exerted on the sealing member 11 by the medium 18 having the lower medium pressure. The medium pressure of the medium 17 exerts forces on the pressure surface (s) 15 either directly or indirectly after deflection at, for example, the chamfer 9, in this case in the region of the gap 19 formed between component 2 and sealing element 11.
- the force generated by the medium pressure depends on the printing surface (s) 15 or the ratio of the printing surface (s) 15 to the printing surface or surfaces 21 on which the pressure of the medium 18 acts at the lower pressure decreases.
- the geometry of the sealing element 11 is therefore chosen so that the product Pressure surface (s) 15 and the first medium pressure is always greater than the product of pressure surface (s) 21 and second medium pressure.
- FIG. 4 shows different variants or installation situations of sealing arrangements 8 according to the invention. For the sake of clarity, only one half of the otherwise essentially mirror-symmetrical arrangements is shown.
- the reference numerals used correspond to those which have already been used in FIGS. 1 to 3 and denote identical or corresponding features, so that a repeated description is dispensed with and only deviating or additional features are described in greater detail.
- the sealing arrangement 8 shown in FIG. 4A corresponds essentially to that of FIGS. 2 and 3, with the difference that the sealing element 11 has a more rounded contour.
- the sealing system 7 is here marginal, ie at the edge of the abutting sides 3 to the side surfaces 13 of the components 2, arranged. In contrast, FIG.
- FIG. 4B shows the installation of a sealing system 7 in a groove 23, which is arranged at a distance from the side surface 13 of the component 2.
- the sealing system 7 is introduced with its basic body 10 into a chamfer 9 provided in the groove 23, for example by gluing.
- the sealing system 7 in FIG. 4C has an anchoring foot 24, which engages in a corresponding recess 32 of the component 2 or is encapsulated during setting in concrete.
- the main body 10 has a sealing lip 31, which is formed by arranging a groove 25 in the base body 10.
- the channel 25 is connected by means of a connecting channel 26 with the gap 19, so that medium 17 penetrate here and provide by exerting a corresponding pressure for a reliable seal between the base body 10 and component 2 and can prevent circulation leakage.
- the sealing lip 31 thus fulfills its sealing function in the same way as the sealing element 11.
- the sealing lip 31 shown in FIG. 4D is in engagement with a corresponding recess 32 and thus also has the function of an anchoring foot. This is not required. Rather, for example, in the case of the sealing arrangements 8 shown in FIGS. 4A and 4B, a corresponding channel 25 may be provided which communicates with the medium 17 via a corresponding connecting channel 26, so that the medium pressure ensures that the sealing lip 31 abuts the component 2 is pressed.
- FIG. 5 shows further embodiments or installation situations of sealing arrangements 8 according to the invention.
- the main body 10 of the sealing system 7 is here designed so that a lip 22 rests in the installation on the wall of the groove 23, 29 of the component 2.
- the lip 22 and the sealing element 11 form a gap 19, in the medium 17 can penetrate.
- the contact pressure of the lip 22 on the component 2 prevents circulation leakage around the base body 10.
- the basic body 10 and the sealing element 11 form an angular structure, the sealing element 11 can be pivoted or pivoted about the joint 16.
- the sealing system 7 is arranged in each case in FIGS.
- FIGS. 5A and 5 B in a groove 23 which is provided at a distance from the side surface 13 of the component 2 in the abutment side 3 of the component 2.
- the sealing system 7 is arranged in FIGS. 5C and 5D of a peripheral groove 29 which is open toward the side surfaces 13 of the components 2.
- the lip 22 terminates with the side surface 13.
- the contours of the respective sealing elements 11 facing the medium 17 are rounded.
- the sealing system 7 is arranged slightly set back relative to the abutment side 3. This is a simple way of preventing the sealing elements 7 from coming to lie against one another over the entire area facing the region 6 or the medium 18.
- the sealing arrangement 8 is provided in a groove 23, which is arranged at a distance from the side surfaces 13 of the components 2 in its abutment sides 3.
- two sealing systems 7 arranged mirror-symmetrically with respect to the contact plane 12 are provided, which contact each other with their sealing elements 11 on the contact plane 12.
- the sealing systems 7 are fastened with their basic bodies 10 in the groove 23.
- the main body 10 has a recess 28 towards the joint 4, which is designed such that the pivotable about the joint region 16 sealing element 11 can be at least partially received therein, so that the gap 19, here between the base body 10 and the sealing element 11th is formed, is not completely closed and the medium 17 can penetrate with the higher medium pressure in the gap 19 or remain there (s. also Fig. 7).
- the medium pressure generated on the mounting side in the groove 23 a sealing contact pressure.
- a mounting situation is shown with maximum joint width, ie the components 2 are so close to each other with the butt sides 3, that the sealing systems 7 just contact each other with their sealing elements 11.
- the sealing elements 11 are not pivoted in the direction of the recess 28 of the base body 10 here. In such an installation situation, the sealing force 20 applied to the contact plane 12 is completely caused and maintained by the pressure difference prevailing between the medium 17 and the medium 18.
- FIG. 7 shows the sealing arrangement 8 according to FIG. 6 in a mounting situation with a minimum joint width.
- the butting sides 3 lie directly with each other with projections 27, which act as spacers.
- the sealing elements 11 are pivoted about the hinge region 16, so that they are largely received in the recess 28 of the base body 10.
- the gap 19 between the main body 10 and the sealing element 11 remains open and thus allows the access of the medium 17 with the higher medium pressure. This ensures that the sealing elements 11 are pressed against the contact plane 12 against each other.
- the sealing system 7 here is ensured that the surface with which the sealing elements 11 abut against each other at the contact plane is as small as possible, preferably smaller than the pressure surfaces 15. This leads to a higher contact pressure at the contact plane 12.
- FIG. 8 shows a further embodiment of the sealing arrangement 8 according to the invention, wherein the sealing system 7 largely corresponds to that described in FIGS. 6 and 7, but with the difference that the sealing systems 7 are located in grooves 29 at the edge of the abutment faces 3 of the components 2 and substantially flush are arranged with the side surfaces 13 of the components 2.
- FIG. 9 shows a further embodiment of the sealing arrangement 8 according to the invention, a redundancy of the sealing elements 11 being provided here.
- Each main body 10 of the sealing systems 7 has two sealing elements 11, which are arranged one behind the other in the longitudinal direction of the joint and are in contact with the opposing sealing elements 11 of the other sealing system 7 at the contact plane 12.
- the sealing elements 11 are at least partially receivable in recesses 28 of the base body 10 while maintaining the gap 19.
- the series connection of two sealing elements 11 increases the safety of the seal. If a leak occurs at the first barrier exposed to the medium 17 with the higher medium pressure, the further passage of the medium 17 through the second barrier is prevented.
- two sealing elements are provided on the main body. However, it is also possible for there to be three, four, five or more sealing elements 11. This depends on the desired application and safety standard.
