摘要： PROBLEM TO BE SOLVED: To rotate a leader greatly in a normal plane by constituting a stay as a piston cylinder device and constituting a spherical joint with a receiving base and a truck and supporting the receiving base in a rotatable manner relative to the truck. SOLUTION: When assembling an excavating device, a leader is pivotally attached to a catch folk. Then, a lower spherical end 12 of a piston rod 11 constituted as a piston cylinder device is inserted into a receiving base 14 of a spherical joint 13 and a spherical recess of a holding plate 15 for supporting. Then, pins 19 and 19' are inserted into holes 18 and 18' of the receiving base 14, the spherical joint 13 is coupled to a supporting plate 17 and fixed to the top of the truck through a base plate 16. Moreover, the upper end portion of the stay is pivotally attached to the upper portion of the leader. By operating the stay by using the above, the leader can be rotated with a large angle in the normal plane, brace holes are drilled in adjacent to the normal hole, and then brace fixing method can be carried out.

摘要： PROBLEM TO BE SOLVED: To facilitate movement of sway-checking device by providing longitudinal-axis rollers at portions for guiding a rod and by providing lateral- axis rollers rolling on slide metal fittings surrounding guide pipes of a leader and on the guide pipes. SOLUTION: Slide metal fittings 12 surrounding a pair of right and left guide pipes 6 of a leader and sliding thereon are fitted on the side facing the leader, while lateral-axis rollers 15 rolling on the guide pipes 6 are fitted. Besides, a plurality of longitudinal-axis rollers 16 are provided at portions for guiding a rod inserted therethrough and thereby lower sway-checking device 11 is formed. The lower sway-checking device 11 is fitted to the lower part of the leader of an auger excavator. Even when a large vertical component force is applied to driving apparatus and an excavating mechanism such as the rod in the case of oblique excavation, the lateral-axis rollers 15 roll on the guide pipes 6, according to this constitution, and therefore the lower sway- checking device 11 can move with ease. Since the rod rotates on the longitudinal-axis rollers 16, besides, rotation and movement of the rod can be facilitated.

摘要： PROBLEM TO BE SOLVED: To make the movement of a drilling machine easier by attaching slide fittings, which surround a guide pipe of a leader and slide, to a drive device and also attaching a roller which turns and moves on the guide pipe. SOLUTION: Slide fittings 11, which surround a pair of right and left guide pipes 6 of a leader and slide, are attached to upper and lower portions on the side facing the leader of a drive device 7 which rotates a rod having a drilling blade at the tip. Also, a roller 12 which rolls on the guide pipe 6 is attached to a drive device 7. A chain is intermeshed between a driven sprocket attached to an upper end portion of a leader and a driving sprocket attached to a lower end portion of the leader, and the chain is then coupled to a drive device 7. By doing this, even through a great normal component of force is applied during diagonal drilling, the roller 12 rolls on the guide pipe 6 so that the drive device 7 can be easily moved.

摘要： PROBLEM TO BE SOLVED: To accelerate the thawing of frozen soil with a small facility by burying an electric heater directly feeding an AC current to a thawing pipe for heating in the frozen soil. SOLUTION: A bottom plate 8 made of a steel plate is welded at the tip of a thawing pipe 1 made of a conducting ferromagnetic substance to close it. A nonmagnetic cylindrical conductor 2 has multiple bore holes 6 on the peripheral wall and partition plates 3 with pressure equalizing holes in it, it is concentrically stored in the thawing pipe 1, and its tip 9 is welded to the bottom plate 8 and electrically and mechanically fixed. The peripheral wall of the cylindrical conductor 2 is supported via insulators 3, 4 to electrically insulate it. The thawing pipe 1 and the cylindrical conductor 2 are connected to an AC power terminal 21. When an AC current is fed under the conditions satisfying the prescribed equation, the current is concentrated on the inner surface of the thawing pipe 1 as a skin current 31, and it nearly uniformly flows on the cylindrical conductor 2. The thawing pipe 1 is largely heated, and the cylindrical conductor 2 is additionally heated. Heat is transferred by multiple partial natural convection currents passing through the bore holes 6 in the partitioned space in the thawing pipe 1, and the difference between the upper and lower temperatures in the thawing pipe 1 is small.
