摘要： PURPOSE:To properly and safely remove earth. CONSTITUTION:An auger screw 1 is formed out of a rotating shaft la and a screw blade 1b. A base frame 2 is fixed to the leader mast 3 of the screw 1. Also, a holder frame 4 is journalled to the base frame 2 and can reciprocatively turn on the operation of a hydraulic cylinder 5 about a journal 4a. A turning shaft 6 is connected to the upper and lower arms 4b and 4c of the frame 4, so as to be freely rotatable. Furthermore, the shaft 6 is integrally fitted with a spiral body 7 for scraping drilled earth. In this case, the body 7 is formed out of an upper spiral side 7a, a lower spiral side 7b and a spiral external side 7c formed between the external peripheral ends of the sides 7a and 7b. The upper and lower spiral sides 7a and 7b form a spiral plane in a direction opposite to the screw blade 1b, and the radius (r) thereof is approximately equal to the radius R of the blade 1b. Also, the breadth 7c of the spiral external side 7c is sized to be slightly smaller than the pitch P of the blade 1b.

CONSTITUTION:A shaft is initially excavated to construct a shorting member 6 to an internal wall, and an expansion rod 22 is extended to push the internal surface of the shoring member 6 with a pushing plate 23 after an excavator 4 is installed in the shaft to position a body thereof horizontally. After that, expansion legs 3 are contracted to turn only one of bearing columns 2, and it is approached to a driver's seat 1. Then, the excavator 4 is circled by a rotary column 13, and the primary excavation range of the shaft is excavated together with the expansion of a link arm 42. The bearing columns 2 are returned, the expansion legs 3 are extended to an excavated bedrock to bear the body, and the secondary excavation range is excavated with the same procedure. The whole section is excavated by repeating the procedure. According to the constitution, work efficiency can be promoted.

摘要： PURPOSE:To save power and save number of workers by forming the device with a first drive means for reciprocating a compression space having a throwing port, and a discharging port, and a compressive discharge plate turning around a supporting shaft from one side to the other side and a second drive means for moving the compression space and the plate from the other side of the throwing port toward the discharging port. CONSTITUTION:A waste thrown into a hopper is thrown from a throwing port, 1a in a compression space 2. The waste in the compression space 2 is compressed and volume of the waste is reduced by operating a hydraulic cylinder for compression 8 and turning a compressive discharge plate 9 to arrow A direction if the compression space is full of the waste. The same operation is repeated until the waste is fully compressed and volume reduced by throwing the waste and again the waste is compressed and volume reduced. discharge gate 11 is taken back to open an discharging port 1b if the waste in the compression space 2 is fully compressed and reduced. At the same time, a hydraulic cylinder for discharging 10 is actuated and the waste in the compression space 2 is discharged to a waste storing bag while turning the compressive discharge plate 9 toward the discharge port, 1b.

摘要： PURPOSE:To promote the efficiency and safety of excavation work by mounting tables on guide rails constructed spirally along the internal surface of a shaft so that they are capable of sliding, and mounting an excavator capable of shaking a head and expansion on them to form an excavating device. CONSTITUTION:Shorting members 2 are constructed to the internal surface of a shaft, and guide rails 1 are so constructed that it has about three full circles spiral. After that, sliding tables 3 are loaded to the guide rails 1 to mount an excavator 5. Then, the excavator 5 capable of shaking a head in up and down and horizontal directions by two jacks 53 excavates the whole section of the shaft by circling two stages of up and down guide rails 1 with them as the reaction force. The guide rails 1 are successively removed from above in accordance with the advancement of excavation to make re-shoring of them downward, and excavated earth is discharged by movement of an earth loading device 6 mounted on the guide rails 1. According to the constitution, excavation efficiency is promoted, and a construction period can be reduced.

摘要： PURPOSE: To improve the follow-up function of an auger screw for a vertical motion under the maintenance of a high earth removal function by continuously scraping sediment with a scraping blade rotating about a rotary shaft laid near the auger screw. CONSTITUTION: When a motor 13 is started concurrently with the start of an excavation process via the rotation of an auger screw 20, a plurality of scraping blades 12 and so forth start rotation about a rotary shaft 11 laid near the auger screw 20. Then, the blades 12 pass space between the screws 22 of the auger screw 20, and continuously scrape out sediment transferred with the auger screw 20. In this constitution, the free end of an intermediate link journalled to the shaft 11 is energized toward the contact direction of the shaft 11 with a spring force, thereby enabling the blades 12 to be reset in a direction orthogonal with the shaft 11. According to this construction, sediment can be continuously discharged with certain directionality at all times, and is not heaped around the auger screw 20.

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 raise safeness of a curing cover device by a method in which a curing cover is pivotally attached in an opening or closing manner to the inner edge tiered base frame of the opening of a slab and a handrail tube attached to the curing cover is connected with the other end of a support tube attached to the base frame in a foldable manner. CONSTITUTION:A tiered base frame 2 is formed on the inner edge of the opening 1 of a slab, and a curing cover 5 is pivotably attached to the shaft of the bearing piece of the frame 2 in an opening or closing manner. One end of a handrail 10 is set on a slide tube 1 through a universal joint and the other end is connected with the upper part of a support tube 13 in a turnable manner. In placing the cover 5 on the opening 1, a reinforcing handrail 16 is removed, the tube 12 is pulled out, and the tubes 10 and 13 are bent and turned inwards to close the cover 5. The handrail can thus be exactly set and safely taken out or in.
