Definitions
- the invention is therefore the object of the invention to provide a tubbing expansion as a tubular inner shell of a tunnel or shaft, which allows a controlled and permanently viable and limited deformability in the circumferential direction, the innovations in this seamlessly into the prefabrication and the integrate fast installation of modern tubbings.
- a single compact prefabricated element is thus available, which is brought directly to the place of installation and integrated.
- the necessary coupling with each other can be done for example by welding, clamping or releasable connection means and a combination of everything.
- a preferred embodiment of the invention provides that the compliance element essentially forms a box profile, which has transversal hollow chambers arranged transversely to the circumferential direction of the respective tubbing ring.
- the box shape results in a compact and easy-to-integrate design that forms a virtually self-contained unit.
- the advantage of the clear design lies in the simple and the butt joint filling integration of the compliance element in the tubbing expansion.
- the positive connection to adjacent tubbing rings reduces the expense of a waterproof design to a minimum.
- the continuous hollow chambers "sacrifice" the plastic deformation of the compliance element due to the rock pressure by reducing their volume in a single direction by controlled compression.Thus, the size and the sum of the hollow chambers can influence the later shape of the hollow chamber In addition to the course of the hollow chambers in the longitudinal direction of the tunnel which is transverse to the circumferential direction, they advantageously extend radially, so that the hollow chambers can be viewed from the inside of the tubbing removal a later introduction of, for example, elastically or plastically deformable materials and components in the hollow chambers and a Tübbings same property stiffening by filling with concrete.
- the hollow chambers are formed by a plurality of mutually parallel webs, each extending between two opposite and parallel to the end faces of the tubbing longitudinal walls and two each extending in the plane of the annular surfaces of the tubbing rings Transverse walls extend.
- the individual webs are here crossed at right angles to each other, so that there is a grid structure.
- the advantage here is a higher resistance at the beginning of the pressure load, since the individual webs are first loaded in their longitudinal direction and must "buckle" in order to produce a plastic deformation.
- the longitudinal walls of the compliance element are curved parallel to the longitudinal axis of the tubbing ring to each other inwardly into the interior of the box profile.
- the longitudinal walls of the compliance element designed in this way have full-surface contact with the adjacent shape-adapted front sides of the tubbings. Due to the biconcave mutually extending shape of the longitudinal walls and in each planoconvex shaped end faces of the tubing, there is the possibility that only one side of the compliance element has a solid bond with one of the end faces of the tubbings, while the opposite side only in conforming contact with the front page the other tubbing stands.
- a preferred embodiment of the segmental lining provides that the tubbing rings are spatially resiliently connected to each other via a coupling unit.
- the coupling unit between the tubbing rings and other pipe sections is in this case a detachable connection. This ensures that the different "breathing" in the form of circumferential changes of the tubing rings allows each other and can be largely stress-free, since adjacent tubbing rings can thus assume different diameters without being hindered by a rigid composite with adjacent tubbing rings to become. Overall, the individual segments are thus safely and accurately positioned with each other at the same time spatial freedom of movement.
- the compliance element to the annular surfaces of the tubbing ring in each case has a recess for a seal.
- This recess extends in each case over the sides of the compliance element between the two end faces of the tubbings and forms in cross section a substantially half circular area.
- a further embodiment of the invention provides that the seal is formed from a solid material or a radially flexible hose which can be filled with different media.
- a medium into the interior of the hose, an elastic cross-sectional change of the hose seal is effected, which achieves its sealing effect even in the absence of or only low contact pressure within the annular joint, by itself generates the necessary contact pressure by volume increase.
- a valve which can be reached from the inside of the tubbing construction and which creates a connection to the interior of the seal as a stub line, filling and compression of the seal can also be carried out in retrospect.
- gaseous media it is also possible, for example, to introduce permanently elastic or hardening materials into the seal.
- the hose seal for this purpose is equipped with a second spur line through which a located within the seal and displaced during the repressing medium can escape.
- the tubbing expansion according to the invention thus meets the highest demands on modern and flexible single-shell interior design.
- a spatially flexible coupling of two adjacent ring sections with each other a good accessibility and a problem-free subsequent replacement of the coupling unit or parts thereof is given.
- the spatially flexible coupling In combination with an adjustment element or a compliance element or a combination of the two, it is ensured by the spatially flexible coupling that the different "breathing" in the form of circumferential changes of the individual ring sections with each other is possible and can also run largely stress-free.
- the adjacent ring sections can assume different diameters, without being prevented by a rigid composite with adjacent ring sections. Overall, this makes the individual segments safely and precisely positioned with each other while providing spatial freedom of movement.
