| titleOfInvention | Shield tunneling method and device therefor |
| abstract | PURPOSE:To eliminate an useless construction in a connecting section by excavating the connecting section while assembling a curved part segment after excavation of a shaft, and constructing an adit by use of a separated front drum. CONSTITUTION:A shield machine is formed of a front drum 2, a rear drum 3, a hinge 4 for connecting the both, and an excavating mechanism 5, and both inside surfaces of the contact end between the front drum 2 and rear drum 3 coaxially disposed are fixed by a band steel material 6. A seal material 62 is provided to stop water, and excavation is carried out to a determined depth while assembling a shaft part segment 7. Before constructing a curved part, the shaft part segment 7 is integrated with the rear drum 3, and the contact surface between the front drum 2 and the rear drum 3 is coaked while removing the band steel material 6. A cutter device 21 and an excavator 5 are operated to excavate the connecting section while assembling a curved part segment 71, and a hinge shaft 43 is pulled out from the inside to separate the front drum 2 from the rear drum 3, and an adit is further constructed by use of this front drum 2. Hence, the useless construction in the connecting section can be eliminated. |
