Definitions
- the invention relates to a protective element for connecting to a concrete element of a tunnel construction, which has at least one protective portion having a concrete element facing side, on which at least one connecting element for establishing a holding connection of the protective portion is provided with the concrete element, wherein the protective portion has a bottom portion and / or a wall portion and at least a portion of at least one plastic, and the protective element has at least one seal which is integrally connected to the protective portion, wherein the compound is gas-tight and liquid-tight, and the integral connection of the seal with the protective portion by injection molding is made with the at least one plastic and thereby forms a first portion of the bottom portion and / or the wall portion of the protective portion.
- Such concrete elements or protective element are known from WO 201 1/085734 A1.
- Such concrete elements are referred to in the jargon as "tubbing" and z. B. used in mechanical tunneling by shield tunneling.
- tunnel boring machines comprising a drill head, behind which a cylindrical shield is arranged with a shield shell and a tail shield.
- the shield is of a smaller outer diameter than the drill bit, so there is no direct contact between tunnel wall and shield.
- the concrete elements are positioned on the edge of the sign in the tail shield. They are pressed against the advancing direction of the adjacent last-applied concrete elements and connected to them. Form several concrete elements together a ring over the entire circumference of the tunnel.
- the gap between ring and tunnel wall is filled with mortar, z. B. to prevent subsidence.
- This type of tunnel construction is u. a. also used for the construction of sewers, especially of larger manifolds. In this case, as with other possible uses also, increased demands on the tightness of the cladding of the tunnel.

- this protective layer consists of glass fiber plastic or polyethylene (PE) or according to JP2004132002 of a synthetic resin and in particular of polyethylene (PE), polypropylene (PP), PVC, polyester or vinyl ester and becomes firmly anchored by means of mechanical anchoring Anchored concrete, so that an inseparable connection of the protective layer with the concrete is formed.
- the protective layer is designed so that the only the inside of the tubbing element is covered (JP2004132002) or a side surface of the concrete element is partially also included (WO2005 / 024183A1).
- a seal which projects beyond the protective layer is then provided on the side surface.
- the seal is made of an elastic material, so that when assembling the individual tubbing for tunneling the joints between the adjacent concrete elements are closed by the seal.

- a protective layer is placed on the formwork floor.
- protective layer elements are likewise provided on the side walls of the formwork.
- the formwork has a recess into which the seal is inserted. Subsequently, in conjunction with reinforcement, the concrete is introduced into the formwork. After hardening of the concrete, the tubbing is used as a tunnel extension.
