Zusammenfassung:PURPOSE: To speed up the execution of tunnel work by providing a hydraulic drill, a concrete sprayer, a carrying conveyer, etc., to a portal working platform travelling on a rail and, at the same time, advancing the excavation of a facing, the carrying out of mock, the lining of a wall surface, etc. CONSTITUTION: A facing 1b is excavated with a hydraulic drill 30 on a working platform 10, and the excavated earth (mock) 1c is loaded on a conveyer 64 by means of raking devices 66 provided to both sides of the working platform and a loading auxiliary machine 70 such as a shovel, etc., to move it with a carrying conveyer 50. In keeping pace with the work, the lining of a wall surface 1a of an excavated tunnel is executed by a concrete sprayer 20 equipped with a spraying nozzle 21, etc. Then, the working platform 10 is subsequently moved, and the same stage of work is repeated to excavate a tunnel. By the constitution, a construction period can be reduced.
