摘要： PROBLEM TO BE SOLVED: To facilitate the use even in the mountain district at the time of excavating vertical hole by previously performing the pre-boring, and placing a pilot pipe underground, and applying the reaction force of thrust to the pilot pipe with a vertical hole excavating machine so as to excavate a vertical hole. SOLUTION: A turning motor 55 is driven, and an annular turning base 49 turns a pilot pipe 1 through a driving gear 54 and an annular gear 56. With this operation, a vertical hole excavating machine is rotated around the pilot pipe 1 integrally with the annular turning base 49 so as to excavate the ground with an excavating blade 31. At this stage, fluid pressure is fed to a cylinder 46, which forms a reaction receiver gripper 34, so as to extend a plunger 47, and an elastic pushing body 48 provided at a tip of the plunger is made to pressure-contact with an inner wall of a vertical hole 4. Reaction force of excavation to be applied to the pilot pipe 1 is securely received by the reaction force receiver gripper 34 so as to smoothen the excavation of the vertical hole 4. Consequently, hard work inside of a narrow vertical hole is eliminated, and the workability and the safety can be improved.

摘要： PROBLEM TO BE SOLVED: To increase the efficiency of excavating work and soil dislodging work. SOLUTION: This excavator is provided with a support stand 14 supported and secured to the interior wall face of a vertical hole 11; an upper cylinder 15 provided in such a way as to pass through the center part of the support stand 14 and to be capable of moving back and forth in the vertical direction; and a lower cylinder 18 which is joined to the lower end of the upper cylinder 15 in such a way as to be rotatable relative to the upper cylinder 14 and which has a cutting bit 16 at its lower end and a soil opening 17 on its side. Further, the excavator is provided with a helical drum excavating unit 19, in which a conveying passage for soil excavated by a helical vane is mounted in such a way as to communicate to the soil opening 17, and with a suction pipeline 20 inserted into the lower cylinder 18 through the upper cylinder 15.

摘要： PURPOSE:To conduct the lining of a shaft easily. CONSTITUTION:A segment 51, in which a hollow section 51a is formed, is carried up to a shaft 101 by a hoist 2 while excavating the shaft 101, the segment 51 is gripped by a gripper 10, and an expansion jack is turned by a motor 11, a bearing arm 9 is elongated by the expansion jack, and a lifting and lowering body 5 is lowered by the lifting jack 6, thus mounting the segment 51 on a specified lining molding equipment 12. The process is repeated, the segments 51 are assembled so as to be formed in an annular shape along the periphery of a pit mouth 102, and the annular-shaped segments 51 are fed into the shaft 101 by the lining molding equipment 12. A series of these operation are repeated, thus carrying out a lining on a pit wall 103.

摘要： PURPOSE:To prevent a pit wall from collapsing as excavation proceeds even if an excavated pit is large in diameter, and thereby materialize both the quick maintenance of a pit condition and the security of its stability. CONSTITUTION:A vertical strip folding hinge section 3 directed inward is formed in the longer direction of a spiral corrugate pipe 2 in such a way that it can be contracted in diameter. As excavation proceeds, let the spiral corrugate pipe 2 in a diameter contracted condition pass through the inside of an existing spiral corrugate pipe which is expanded in diameter so as to be pressed on a pit wall 6a, and it is then lowered down. Subsequently, the spiral corrugate pipe lowered down is then expanded in diameter so as to be connected to the lower end of the existing spiral corrugate pipe 2.
