Tunnel portal thermal insulation has important application value in tunnel projects in cold regions. The advantages of tunnel portal thermal insulation: Ensure the safety of the tunnel structure: Through thermal insulation measures, reduce the influence of the temperature difference between the inside and outside of the portal on the tunnel structure, prevent the occurrence of phenomena such as frost heaving and thaw settlement, and ensure the normal use and safety of the tunnel. Prolong the service life of the tunnel: Thermal insulation measures can reduce phenomena such as frost heaving and thaw settlement of the tunnel structure, reduce the wear and damage of the tunnel structure, and prolong the service life of the tunnel.
