ABSTRACT:
There are disclosed a method and a machine for constructing a shaft having a substantially circular cross-section. According to the present invention, the shaft having a shotcrete formed on a peripheral wall thereof can be easily constructed. The shotcrete can be promptly formed on the peripheral wall by spraying concrete on the wall above the water level of the water in the shaft before the wall is damaged. Also, muck excavated from a working face of the shaft can be efficiently conveyed therefrom to outside of the shaft even if the shaft has a depth of more than hundreds of meters.
