| titleOfInvention | Muddy water discharge device in tunnel with muddy water shield method |
| abstract | (57) [Summary] [PROBLEMS] To provide a muddy water discharge device in a tunnel of a muddy water shield method in which muddy water collected in a tunnel is discharged directly to the ground without being collected at the bottom of a shaft. A tunnel (10) is excavated from the bottom of a shaft (4) by a shield machine (10), and a muddy water pipe (14) and a muddy water pipe (1) from a muddy water treatment facility (18) installed on the ground to a face (10a). 6 is provided, and the muddy water pressurized by the mud feed pipe and the drainage pipe is circulated toward the face face to perform a muddy shield construction method. Then, a drain pipe 20 is provided from the bottom of the shaft to a position where muddy water is accumulated in the tunnel, and a vacuum pump 22 is connected to a muddy water outlet of the drainage pipe to suck muddy water in the tunnel. And the discharge port 2 of the vacuum pump A bypass pipe 32 is connected between 2a and the drainage pipe 16; The muddy water is fed into the drainage pipe by interposing a sand pump 34 in the bypass pipe. |
