Zusammenfassung:PURPOSE:To construct a tunnel effectively and economically in a short time, to stick an even and homogeneous waterproof layer automatically without depending on man power and to improve working conditions in a shaft of the tunnel. CONSTITUTION:A waterproof layer 9 is put on the inner surfaces of segments lined primarily, by spraying by a spraying nozzle 4 while a waterproof layer- spraying robot 1 is being self-propelled by a traveling car 2 and while a turning boom 3 is being turned at a fixed speed of turning, as a shield machine is advanced for excavation. After that, the waterproof layer 9 is secondarily lined with concrete cast in site and a shield tunnel 8 is constructed.
