Abstract

PURPOSE: To improve the working efficiency of cut-off of water by slidably engaging a waterproof sheet with a plurality of guides which are arranged on side surfaces of the natural ground in parallel with the direction of a tunnel and at intervals in the circumferential direction of the tunnel.
CONSTITUTION: A plurality of guides G1, G2,... are arranged on three side surfaces of primary concrete sprayed on a rock mass 2 of the tunnel in parallel with the direction of the tunnel, and at predetermined intervals in the circumferential direction of the tunnel. The rear surface of a waterproof sheet 1 has suspenders S1, S2, secured thereto, depending on the interval of the guides G1, G2,.... Then, the sheet 1 is moved in the direction of the tunnel while key portions of the respective suspenders S1, S2,... being sequentially engaged with hook portions of fasteners T1, T2,... attached to the guides G1, G2, respectively.
