Title:

STRUCTURE OF SECONDARY LINING ON INNER SURFACE OF TUNNEL AND METHOD FOR CONSTRUCTING THE SAME

Document Type and Number:

Japanese Patent JP2000192790

Kind Code:

A

Abstract:

To reduce the thickness of a secondary lining applied to the inner surface of a tunnel and to facilitate construction work therefor.

Mounting metal fittings 3 each having an L shape on cross-sectional view are pressed against and attached to the inner surface of a tunnel by means of anchor bases 4. Supporting steel members 11 each having a T shape on cross-sectional view and having a connecting piece 11a formed at approximately the center of its supporting plate part 11b are supported along the circumferential direction of the tunnel with intervals to one another in the direction of the axis of the tunnel, by connecting the connecting pieces 11a to the fixed parts 3b of the mounting metal fittings 3. Both ends of a board B are locked by means of locking metal fittings 15 to the supporting steel members 11 disposed in the direction of the axis of the tunnel. A filler C is packed between the inner surface of the tunnel and the board B and cured to integrate the inner surface of the tunnel with the board B.
