Narrow-space circular shaft temporary pilot tunnel

The utility model relates to the technical field of temporary pilot tunnels, in particular to a narrow-space circular shaft temporary pilot tunnel which comprises a shaft way and a shield tunneling machine, a hole frame is arranged on the surface of the shaft way, a shield tunnel is arranged on the surface of the shaft way, the shield tunneling machine is arranged on the inner side of the shield tunnel, an inner lining and an outer lining are arranged on the surface of the hole frame, and the outer lining is arranged on the surface of the hole frame. The outer surface of the outer lining is fixedly connected with a glass fiber anchor rod, and a glass fiber rib is arranged on the inner side of the hole frame. According to the scheme of the glass fiber reinforced plastic bar small pilot tunnel, in an ultra-deep round well, the tunneling efficiency after shield large split starting is improved, left and right line rear pilot tunnels are optimized into the small pilot tunnels so as to meet the shield rapid tunnel
