A section through the gasket shows a cell structure of apertures that allows, by design, the gasket to be compressed in a known way as the segments are installed and pushed together during installation of a lining ring. Generally the larger the gasket structure, the greater the groundwater pressures that can be handled, but much depends on the quality of manufacture and materials. Application The gaskets placed between lining segments in many TBM-bored tunnels are a vital component in ensuring a long and useful life for the tunnel by protecting the lining and the tunnel interior from ingress of groundwater, and other material, under pressure.? Tunnel segment gasket is an important component that ensure the life of the tunnel. It protects the interior of the tunnel from intrusion of groundwater or other material into the tunnel. At present,its designs and materials are still evolving. With the improvement of technology, more different types and materials tunnel segment gaskets have appeared. The gasket pressure rating depends on the compound, size and shape of the internal structure of the gasket. The gasket is usually designed to a certain pressure with a maximum gap and offset condition for a worst-case scenario. It depends as well on the maximum load deflection force that is allowed in the specification, or requested by the contractors. All these factors impact the gasket performance and sealing capacity. Hydrophilic EPDM Rubber Extruded Tunnel Segment Gaskets Features We have EPDM and natural rubber tunnel segment gasket. Porous tunnel segment gasket can reduce the compressive stress when installing. In addition, our products have aging res
