摘要： PURPOSE:To prevent the inflow of a back-filling agent by arranging tail seals on the tail part inner circumference of a shield body, circumferentially forming a determined number or more of chambers between the respective seals, and injecting a high viscosity to the forefront chamber and the last chamber, and a low viscosity to the chamber adjacent to the last part. CONSTITUTION:Tail seals 12-15 are arranged in four lines on the tail part 5 inner surface of a shield body 1 in the circumferential direction of the body 1, three circumferential chambers 16-18 are formed between the respective seals, and injection holes 19-21 communicated with the outside are formed in the circumferential direction of the tail part 5. Feed ports 22-24 corresponding to these holes are mutually connected by injection pipes 25-27 extending along the outer circumferential part. The supply source 30 of a high viscosity tail seal filler 29 is connected to each feed port 22, 24 to the last and forefront chambers 16, 18, and the supply source 34 of a low viscosity filler 33 is connected to each feed port 23 to the central chamber 17. Hence, the inflow of the low viscosity filler into the shield body can be prevented.

SOLUTION: A separable and self-contained small-diameter shield driving part 2 is integrated at the center of a large-diameter shield driving machine 1 to form a driving machine, and the driving machine is brought in the starting shaft 38. After a tunnel 47 is constructed through the use of the driving machine, the small-diameter shield driving part 2 of the driving machine is pulled to the inside of the machine and returned to the location of the starting shaft 38 via the tunnel 47 in the shield driving machine. The small-diameter shield driving part 2 is provided in a shield frame 7 of the large-diameter shield driving machine 1 in such a way as to be pulled to the inside of the machine. A small- diameter cutter head 21 smaller in diameter than the small-diameter shield driving part 2 is rotation-freely provided for the small-diameter shield driving part 2. The small-diameter cutter head 21 is provided with a large-diameter cutter head 4 for performing excavation in front of the large-diameter shield driving machine 1.
