摘要： PROBLEM TO BE SOLVED: To provide a gravel pipe burying apparatus which prevents gravel from being caught in the back face of an auger head to improve excavation efficiency. SOLUTION: A rotary supporting member 14 comes in contact with the back face of the auger head 21 when the auger head 21 retreats. This rotary supporting member 14 is configured in such a way that the front end the supporting member 14 comes in contact with only the outer periphery of the back face of the auger head 21, and that the radial dimension of an annular contact portion 14a of the supporting member 14 can be determined to be about several millimeters. As a result, earth and sand and gravel caught in between the back face of the auger head 21 and the annular contact portion 14a of the supporting member 14 are less in amount. This surely prevents such an accident that the auger head 21 become incapable of retreating after catching gravel of a large diameter. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To increase the efficiency of construction by dispensing with measures for reinforcement of steel shell elements, increasing construction accuracy, shortening a period of excavation time and eliminating an unexcavated section between the steel shell elements.
SOLUTION: Excavation equipment 10 is connected to a thrust transfer member 6
1 on the side adjacent to the thrust transfer member 6
1 , from a state in which the thrust transfer members 6
1 , etc. with a predetermined length are annexed in file to one side surface of the prepenetrating steel shell element 3
1 ; subsequently, the steel shell element 3
2 with a predetermined length subsequently follows the thrust transfer member 6
1 , and is put into the state of being connected to the steel shell element 3
1 having already penetrated; the thrust transfer member 6
1 with the predetermined length sequentially follows the thrust transfer member 6
1 ; a thrust transfer member 6
2 with a predetermined length is sequentially annexed to one side surface of the steel shell element 3
2 for penetration; concurrently with that, the thrust transfer members 6
1 and 6
2 arranged in these two locations are pushed in by a base-pushing jack 11; and the steel shell element 3
2 penetrates while being towed indirectly. The procedures are repeated in sequence.

摘要： PROBLEM TO BE SOLVED: To mount a blocking unit in even a narrow arrival shaft satisfactorily.
SOLUTION: This removing and backfilling apparatus 1 for the propulsive tunnel is provided with a substantially cylindrical casing 2, and a sleeve B can be connected with a fringe part of an opening at one end of the casing 2. A first cutter member 3 is protrusively provided in a fringe part of an opening at the other end of the casing 2, which is rotated around a shaft axis C (an arrow mark D) to excavate the ground G on an outer peripheral side of a propulsion pipe A. When backfilling, the blocking unit (not shown) is attached to the casing 2 while connected with the sleeve B to prevent a backfilling material from entering into the sleeve B. Since it is unnecessary to remove the whole casing from the sleeve B when attaching the blocking unit, even the narrow arrival shaft for mounting the blocking unit can be satisfactorily utilized in this construction work, and the time required for excavating the arrival shaft can be shortened.
