TBM High Pressure Sealing Gasket for Tunnels Made by Tunnel Boring Machine

摘要

The present invention relates to a water blocking gasket, preventing water from penetrating into a tunnel from the outside of the tunnel through a tunnel wall. A TBM method is a method for forming the tunnel wall by assembling precast concrete segments on a rear side of an excavation work while proceeding the excavation work by using a TBM machine. The present invention is installed between the segments of the tunnel wall to prevent intrusion of the water.
