Definitions

  • the invention relates to a sealing arrangement for shaft and tunnel constructions.
  • Each body that is assembled from single monolithic components has contact joints. This applies, for example, for shaft end tunnel constructions, which consist of precast elements (lining segments). For example, in case that a tunnel construction shall be constructed and used under groundwater level, there is a need for water tightness of the whole construction. For a construction consisting of a plurality of prefabricated individual parts not only the requirement for water tightness of the monolithic components arises but also that of the sealing of the contact joints between the components against the hydrostatic pressure.
  • Sealing arrangements for sealing constructive joints in tunnel constructions made of prefabricated components are generally known, see e.g. DE 102005039253, DE 102005039056, U.S. Pat. No. 4,946,309, EP 0222968, EP 0441250 and EP 0995013.
  • a sealing element is glued into a groove circumferential around the abutting sides in a constant distance from the outside surface of the lining segments.
  • the sealing effect of the sealing system is achieved after the assembly of the lining segments in that the sealing elements within the joints are contacting each other mirror-symmetrically.
  • the contact has to be effected at least with a surface pressing power, which is greater than the pressure in the adjacent pressure medium.
  • the desired surface pressing power is adjusted by choosing the elastic compression behavior of the two sealing elements depending on the displacement of the compression.
  • the intended surface pressing power is reduced in case of a subsequent increase of the joint width, so that the danger of a leakage is hereby also increased.
  • the sealing elements in the contact joints of the tunnel shall preferably have an unlimited lifetime.
  • the technical requirement is defined as a 100 years lifetime.
  • the decline of the elastic tension forces (up to 40%) over time has to be accounted for by an increased starting tension when assembling the sealing arrangement. All of the already unwanted force reactions of the elastic tension forces are increased accordingly.
  • the sealing arrangements according to the prior art only act singularly.
  • a leakage inevitably leads to a leakage stream of surrounding medium, e.g. water, into the tunnel.
  • the targeted localization of the leakage is problematic in view of the wall thickness and the spreading possibilities in the contact joints of the components.
  • a sanitization of the leakage can therefore not be performed locally on the inner side of the sealing system and always requires great efforts.
  • redundant sealing systems can only be realized with great effort and in big tunnels.
  • the invention provides a sealing arrangement for shaft and tunnel constructions comprising
  • each of the sealing systems has at least one sealing element projecting to the joint, with which the sealing systems lie against each other on a contact plane, and wherein each of the sealing elements has at least one pressure area exposed to the medium with the higher medium pressure, so that a sealing force is applied between the sealing elements at the contact plane, which is greater than the force applied without the pressure difference, and which generates a contact pressing, which is greater than the pressure difference.
  • the elastic tension forces which are generated when the sealing systems, after the systems have been brought into contact with each other, are pressed against each other by reducing the joint width are reduced or avoided completely compared to sealing arrangements of the prior art, and the necessary surface pressing pressure is achieved by a self-sealing force effect of the medium pressure.
  • the sealing elements of the sealing system are designed geometrically in such a manner that they exhibit pressure areas against a low pressure or the atmosphere after mutual contact. On these pressure areas a differential pressures acts because of the pressure difference between the media, resulting in the force securing the necessary surface pressing pressure at the area, with which the sealing elements lie at each other at the contact plane.
  • the pressing pressure is inevitably always adapted to the respective medium pressure and essentially independent from the joint width achieved after contact.
  • the necessary contact pressing considerably smaller reaction forces are necessary.
  • the contact pressing can be adjusted.
  • a misalignment of the components does not change the quality of the sealing, because the contact does not depend on the symmetry of the sealing elements.
  • the sealing element is pivotable or tiltable about a hinge.
  • the term “hinge” as used herein refers to a region of the sealing system featuring or forming a static center, around which the pivoting motion takes place and which itself does, at least essentially, not participate in the pivoting motion.
  • the hinge region may have a reduced cross-section compared to the adjacent base body and/or sealing element and/or a softer material.
  • the hinge connects the base body of the sealing system with the sealing element.
  • the pivoting or tilting motion can be in the direction of the joint or in the opposite direction.
  • the force component of the contact pressing generated by a possible pretension of the sealing element is as small as possible compared to the force component of the contact pressing generated by the media differential pressure, i.e. the pressure difference between the media.
  • the force component of the contact pressing generated by the media differential pressure is >50%, further preferred >60%, >70%, >80%, >85% or >90, especially preferred >95%, >96%, >97%, >98% or >99%.
  • contact pressing or “surface pressing power” as used herein is to be understood as being the pressure at the contact area, i.e. the area at which the sealing elements are contacting each other at the contact plane.
  • pressure area as used herein means any surface of the sealing system, in particular of the sealing elements, exposed to the medium pressure.
  • each of the sealing systems has a base body, with which the sealing system is attached to the component.
  • the attachment can be achieved in many ways, for example by way of adhesion, concrete encasement, force fitting, or by means of anchoring feet.
  • the elastic sealing system consists of elastomeric material.
  • an elastic body designates the characteristic of a body or a material to change its shape under the application of a force and to revert to the original shape after removal of the acting force.
  • an elastic body is in particular to be understood as being a body having an elasticity modulus of 0.1 or lower, preferably 0.01 to 0.1.
  • An example of an elastic material is silicone rubber.
  • elastomeric material refers to a rigid but elastic natural or synthetic polymer, the glass transition point of which is preferably below room temperature (25° C.). Examples for elastomeric materials are ethylene propylene rubber (EPM), ethylene propylene diene rubber (EPDM), styrene butadiene rubber (SBR), and nitrile butadiene rubber (NBR).
  • each of the sealing systems has at least two sealing elements projecting to the joint with which the sealing systems lie against each other at contact planes.
  • the provision of two, three or more, and thus redundant, sealing elements provides enhanced sealing safety.
  • the sealing systems can be arranged in a groove circumferential around the abutting sides of the components and/or at a bevel of the components circumferential around the abutting sides of the components.
  • the groove or bevel will not have to be disposed at a distance from the edge of the abutting sides of the components, but can also be arranged at the edge of the abutting sides, in which case the sealing systems are arranged flush with the side surfaces of the components. Thus, leakage channels are avoided, which otherwise would form and, in embodiments according to the prior art, would additionally have to be sealed with a filler strip.
  • a crack is present between the component and the sealing element, which crack is open to the medium with the higher medium pressure.
  • a crack between the base body and the sealing element is present, which crack is open to the medium with the higher medium pressure.
  • the at least one sealing element may, for example, be arranged in a recess of the base body, or the base body may be provided with a lip contacting the component. The medium with the higher medium pressure can enter the crack and thus exert a respective force effect on the sealing element leading to the pressing operation of the sealing elements.
  • the sealing element may be designed in the form of a lip connected to the base body via a hinge, the lip being pivotable around the hinge.
  • the base body and the sealing element pivotable around the hinge form an essentially angulate form, the sealing element or the sealing lip being preferably angled in the direction of the area with the higher medium pressure.
  • the sealing systems are each monolithically designed, thus each forming a physical unit.
  • Base body and sealing element preferably form such a physical unit, and may consist e.g. of a single piece of elastomeric material.
  • the sealing system is preferably designed monolithically. The redundancy already mentioned may, for example, also be achieved by arranging two or more sealing systems, which, for example, each possess a sealing element, twice or multiple times in parallel, e.g. together in a groove or at a bevel.
  • the sealing systems are arranged generally mirror-symmetric to each other, i.e. mirror-symmetric in relation to the contact plane.
  • the sealing systems are designed generally wedge-shaped and are arranged at a bevel of the components circumferential around the abutting sides of the components.
  • the forces acting on the pressure area(s) of the sealing element due to the medium pressure are redirected from the bevel in direction of the contact plane, such that a respective sealing force is generated.
  • the invention provides a method for sealing a joint between components of shaft and tunnel constructions, the joint connecting a first area with a first medium and a second area with a second medium, wherein
  • the components are each, at their abutting sides, equipped with an elastic sealing system, which has a sealing element projecting to the joint, b) the sealing systems are, with their sealing elements, brought into contact at a contact plane, and c) by means of a pressure difference, which is present or generated between the first medium and the second medium, a force is exerted to pressure areas of the sealing elements directed to one of the areas in such a manner, that a sealing force is generated between the sealing elements at the contact plane, which is greater than the force generated without the pressure difference, and which generates a contact pressing greater than the pressure difference.
  • a sealing element is used that is pivotable or tiltable about a hinge.
  • the hinge may, for example, be a region of the sealing system having a reduced cross-section or is made of a softer material.
  • the force component of the contact pressing generated by the pressure difference is >50%, preferably >60%, >70%, >80%, >85% or >90, especially preferred >95%, >96%, >97%, >98% or >99%.
  • the contact area, with which the sealing elements are brought in contact at the contact plane is smaller than the pressure area(s) exposed to the higher medium pressure, wherein the ratio of the pressure area(s) to the contact area is preferably at least 2:1, further preferred at least 5:1, at least 10:1, at least 20:1 or at least 30:1, and especially preferred at least 50:1.
  • the sealing systems used in the method preferably have a base body and are attached to the component with this base body, for example by adhesion, concrete encasement, force fitting, or by means of anchoring feet.
  • sealing systems of elastomeric material are preferably used.
  • sealing systems that have at least two sealing elements projecting to the joint with which the sealing systems are brought into contact at contact planes.
  • the sealing systems are arranged in a groove circumferential around the abutting sides of the components and/or at a bevel of the components circumferential around the abutting sides of the components.
  • the sealing systems are arranged flush with the side surfaces of the components in a groove or bevel at the edge of the abutting sides of the components.
  • a crack may be provided between the component and the sealing element and/or between the base body and the sealing element, the crack being open to the medium with the higher medium pressure.
  • the at least one sealing element may, for example, be arranged in a recess of the base body, or the lip of the base body can be arranged between the sealing element and the component in such a manner, that a crack remains between the base body and the sealing element, in which crack medium can enter.
  • sealing systems are used that are designed generally wedge-shaped, and the sealing systems are arranged at a bevel of the components circumferential around the abutting sides of the components.

  • Other fixing possibilities for example concrete encasement, anchoring by means of an anchoring foot etc. or combinations thereof are, of course, also possible.
  • the sealing systems 7 which are preferably made in one piece of an elastomeric material, are arranged mirror-symmetric in relation to a contact plane 12 and have a base body 10 and a sealing element 11 .
  • the sealing element 11 is connected with the base body 10 via a hinge region or a hinge 16 and is tiltable or pivotable around the hinge 16 , such that the sealing elements 11 are tilted or pivoted in the direction of the respective bevels 9 when the distance between the abutting sides 3 is reduced, i.e. The joint with is reduced.
  • the sealing elements 11 contact each other at the contact plane 12 and bridge the joint 4 in this manner.
  • the sealing systems 7 are each attached with their base body 10 at the component 2 .

  • the second medium 18 in the second area 6 i.e. the inner medium, for example the atmosphere inside the tunnel.
  • the medium 17 with the higher pressure exerts a force on the pressure areas 15 of the sealing elements 11 , such that the sealing elements 11 generate a sealing force at the contact plane 12 that is greater than the force that would be generated without the pressure difference, and that generates a contact pressing that is greater than the media differential pressure, i.e. the pressure difference between the media 17 , 18 (see in addition also FIG. 3 ).

  • the medium pressure of the medium 17 directly or indirectly after redirection at e.g. the bevel 9 , here in the region of the joint 19 formed between component 2 and the sealing element 11 , exerts forces on the pressure area(s) 15 .
  • the resulting force in direction of the contact area 12 generates a respective contacting pressure at the contact area 12 .
  • the force generated by the medium pressure depends on the pressure area(s) 15 or the relation of the pressure area(s) 15 to the pressure areas 21 , on which the pressure of the medium 18 with the lower pressure acts.
