摘要： PURPOSE:To raise the function or a pile driver by a method in which a leader is designed to be separable into several stages and also to be expandible and tiltable to operating base, and the upper end sheave-hanging arm of the leader is also made foldable to the operating base. CONSTITUTION:An expandible jack is set on the center of two angular pipes. The jack is extended to extend the upper part pipe of a leader 2 to the allowable range of the upper space, and an earth auger 23 is turned for excavation. When machines are removed through low-leveled elevated parts after the end of operation, the auger 23 and the motor 22 are removed from the leader 2, the middle bolt of the sheave-hanging arm 3 is unfastened to divide it into front and rear parts, and the front arm is folded backwards from the part of hinge 32. The jack 15 is shortened, and the leader 2 is fallen down to the machine side and housed in the side of the operator seat 12. The function of the pile driver can thus be raised.

摘要： PURPOSE:To permit the continuous smooth expanding and contracting actions of leader and also continuous and smooth vertical actions of auger by a method in which an auger device is attached to the guide rail of the upper leader of a leader device divided into two upper and lower sections and a penetrating force into the ground is given to the auger. CONSTITUTION:A leader device 1 consists of two upper and lower leaders 11 and 12 which are mutually fitted in a sliding and coming-in and -out manner. An expansible jack 13 is set on the central part of them, guide rollers are set on the upper and lower ends of the upper leader 11, and a link chain is provided. A guide rail 2 is provided to the leader 11, an auger device 3 is attached and fixed to the link chain. The link chain is driven by a drive source 14 attached to the upper end of the leader 11. In case where there is no obstruction on the upper part, the leaders 11 and 12 are extended for use, but when an obstruction is present, they are shortened. Operations can thus be made by the same apparatus regardless of restricted space.

摘要： PROBLEM TO BE SOLVED: To surely feed lubricants by providing a guiding ring over the outer periphery of a push pipe in the circumferential direction thereof, providing a lubricant feed pipe along the outer periphery of the pipe from the ring to a starting shaft, and disposing a delivery port. SOLUTION: After driving a push pipe 5 forward by a predetermined distance, a junction ring 4, which comprises two rings of the tongue and groove joint type, is circumferentially rotatably mounted onto the outer periphery of the pipe 5, while a lubricant feed pipe 2 is disposed in groove or holes formed in the ring 4. And when push or rotation resistance is generated on the pipe 5, lubricant is fed to a spot where resistance is generated. Lubricant is forced into the pipe 2 by means of an inject device 25 to directly feed it to the outer periphery of the pipe 5. Thus frictional resistance between the periphery of the pipe 5 and the ground 10 can be reduced so that sufficient push force and rotational force required for a pipe jacking method can be obtained. As a result, lubricant can be fed over the periphery of the pipe 5 from the outside and feed efficiency of lubricant can be improved.

摘要： PURPOSE: To obtain an easily folding type hanging scaffold for assembling and disassembling, by arranging scaffold boards between erected frames in which a plurality of standards are rotatably connected and putlogs are laid between respectively facing standards and arranging bracings so as to avoid crossing joints of the erected frames. CONSTITUTION: A plurality of standards 21, 21 are rotatably connected and putlogs 22 are laid between the oppositely facing standards to constitute erected frames 20, 20. Scaffold boards 40, 40 are arranged between the putlogs 22 of the oppositely facing frames and bracings 30 are arranged at the positions avoiding the connected parts of the oppositely facing frames. The uppermost frame 20 is rotatably connected to a frame base 50. It is preferable that the frame 20 is pivotted so as to be able to fold to a specified direction of the scaffold board 40. A hanging scaffold constituted to be folded in such a way is transferred to the site in the folded state. The frame base is lifted by a crane or the like. The frames 20 and the scaffold boards 40 connected to the frame base 50 are lifted in turn from the upper members to the lower members. The scaffold is formed by positioning vertically and horizontally due to its own weight.

CONSTITUTION: Switching levers 2, 2 are rotatably attached to both the right and left ends of a support body 1 attached to the head of a steel frame pillar P through pin 1b, and each auxiliary lever 3 is attached to the switching levers 2, 2 and fixtures 2a, 3a such as a hook for hanging the upper edge of a curing net N are provided on the auxiliary levers 3. On the ground, a spreading device A for the curing net N is attached to the head of the steel frame pillar P, and after the lower part of the curing net is tied to the steel frame pillar P, the pillar P is erected at a fixed position, and a prime mover 5 is operated to rotate a driving screw 4 to make a moving piece 6 ascend for opening the switching lever 2 and the auxiliary lever 3 to spread the curing net N. In the case where the steel frame pillar is a corner pillar, the right and left switching levers 2, 2 are composed so as to be mutually perpendicular. The curing net is previously attached and automatically openable, and can be safely and quickly spread without working at an elevated spot.
