titleOfInvention | Method of digging a curved section with earth pressure shield machine |
abstract | [PROBLEMS] To excavate a curved section with an earth pressure shield machine, it is possible to perform the filling work of a backfilling material into a tail void only once while preventing the collapse of an extra moat, thereby enabling efficient and inexpensive construction. Like that. SOLUTION: When excavating a sharply curved section with an earth pressure shield machine 1, a mud material 16 is injected into the extra excavation portion 14 and is held under pressure filling to prevent the extra excavation portion 14 from collapsing. Then, after assembling the segment 8, the tail void 17 is filled with a fast-curing backfill material 18 made of urethane foam. The filling pressure Ps of the fast-curing backfill material 18 starts from the same value as the holding pressure Py (Po <Py <Pu) of the extra moat 14 and when the measured value by the second B pressure gauge 223 becomes equal to or higher than the upper limit value Pt, Stop filling operation.
