Abstract:
To provide a repairing/reinforcing method of a tunnel and a joint structure of panels used for the method by which the effect of reinforcement of the tunnel is enhanced in a shorter period and at a lower cost compared to the conventional method, and the landscape is kept good without finishing work.
The repairing/reinforcing method of the tunnel is as follows. Namely, after spraying fiber concrete onto a primary lining surface of the tunnel, a highly rigid panel is arranged along the primary lining surface by an anchor bolt leaving a predetermined space between the rigid panel and the fiber concrete. Then, the space between the fiber concrete and the rigid panel is filled with non-shrink mortar.
