Zusammenfassung:PROBLEM TO BE SOLVED: To evenly spray a spraying material such as concrete or mortar without defectively sprayed positions while eliminating influences of a TBM excavation at a preset speed against the excavated wall face, in a spraying device mounted under a condition advancing according to the TBM excavation. SOLUTION: At least the head position information and the excavating speed information of an entire section excavation machine 2 are obtained in a real- time system, and the positional information of a shotcrete machine 1 is obtained in a real-time system. The advancing speed of the shotcrete machine 1 is controled so that a speed that the excavation speed of the entire section excavation machine 2 is added to the advancing speed of the shotcrete machine 1 gets to a preset speed against the spraying face.
