<P>PROBLEM TO BE SOLVED: To enable downsizing a concrete injection apparatus that injects concrete to a concrete supply apparatus in the longitudinal direction X of a tunnel by downsizing a feed apparatus 16 of transfer means 15, as a result of the movable distance of a movable supply pipe 4 being made longer than that of a movable pulley 20. <P>SOLUTION: Concrete lining installment equipment on a tunnel inside wall comprises transfer means 15 for moving a concrete supply apparatus which supplies concrete to a wall concrete lining installation frame 2 disposed inside a tunnel in the longitudinal direction X of the tunnel. In the transfer means 15, a feed apparatus 16 having a movable pulley 20 where a flexible pipe 21 connected to a movable supply pipe 4 is looped over, is provided movably in the longitudinal direction X of the tunnel, and in the state where a concrete injection port 25 of the flexible pipe 21 is kept at a fixed position, the movable supply pipe 4 and two movable discharge pipes 11 of the concrete supply apparatus as well as the movable pulley 20 of the feed apparatus 16 are moved in the longitudinal direction X of the tunnel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
