Tunnel Lining Shotcrete Lining Systems Inc Norway, the country with the world’s longest road tunnel, has designed its own waterproofing standard, created to fit norwegian harsh weather conditions. Norge, landet med verdens lengste veitunnel, har designet sin egen vanntettingsstandard, laget for å passe norske værforhold. for tunneler med dryppende vannforhold anbefaler vegvesenet å bruke type lll membran, en forsterket membran som skal gi styrke og stabilitet.
Tunnel Lining Insuwrap Protan recommends to use infraplan p15r or p15rx for tunnel lining type iii. norwegian road authorities recommend type iii reinforced membrane for tunnels with dripping water. strengthen and stabilize your project. • not only serious structural problems, but also environmental problems encountered with actual lining behavior are related to the absence of support (voids left between the lining and the ground) rather than intensity and distribution of load. therefore, construction goes hand in hand with design. • the lining is a confined flexible ring. Pelld type iii, 1,5mm protan infraplan tf portfolio is a group of polyethylene (pe) tunnel membranes, tested and validated according to en 13491 – geosynthetic barriers. in line with the requirements in the norwegian handbook n500 (march 2022). Für tunnel im sickerwasserbereich empfielt die norwegische strassenbehörde den abdichtungstyp iii. hierzu wird eine gewebeverstärkte kunststoffdichtungsbahn (kdb) in 1,5mm dicke verwendet.

For tunnels with dripping water conditions, the norwegian road authorities recommend to use a type iii membrane, a reinforced membrane that will provide strength and stability. the system consists of a waterproofing membrane mounted on an anchor grid, spaced with approximately 50 cm to the shotcrete covered rock mountain. Til tunneler med drypvandsforhold anbefaler det norske vejdirektorat at bruge en type lll membran, en forstærket membran, der vil give styrke og stabilitet. systemet består af en vandtætningsmembran monteret på et ankergitter med en afstand på ca. 50 cm til den sprøjtebetondækkede sten bjerg. During the design of the lining matrix the aim was to determine which type of lining is more efficient for tunnel function. tunnel functions are divided into water conveyance tunnels, road tunnels, railway tunnels, storage tunnels and defense tunnels. In addition to protecting the tunnel, protan tunnel membranes also help to protect the area both inside and surrounding the tunnel by, for example, preventing groundwater pollution and the leakage of oil or chemicals from the tunnel out into nature.
