摘要： PROBLEM TO BE SOLVED: To force-feed a casing without excavating and discharging soil, by rotating the casing in which a tubular body or a screw rod is provided along the inner wall face and jetting a pressurized fluid from the tubular body and rotating the screw to form a low density zone of soil at the inner wall face of the casing. SOLUTION: A cylindrical casing C made of steel or the like is the front head casing for the construction of a shaft. An excavating cutter C2 is fitted to the lower edge C1 and a tubular body 1 is detachably provided vertically to reach almost the lower edge C1 at the inner wall face C3. The front head casing C is set to a shaft-construction machine and rotated to settle the casing by the force-feeding action while excavating the ground by the excavating cutter C2. Compressed air, pressurized water, or mud slurry according to a soil quality, is jetted from a plurality of ejection holes 1C formed on the tubular body, from a pressurized fluid supplying device through a swivel 3 or the tubular body 1, while excavating the ground. The front head easing C is pressed in the ground while forming a low density zone G2 over the whole peripheral part near the inner wall of the casing C.

摘要： PROBLEM TO BE SOLVED: To excavate and discharge soil in a shaft, by rotating a screw conveyor fitting an excavation cutter at the lower end, together with a casing, when constructing the shaft by pressing in with rotation the casing having an excavation cutter fitted at the lower end. SOLUTION: In the construction of a starting shaft or an arrival shaft for installation of sewage pipes or a manhole, a casing C in which an excavation cutter S is fixed to the lower end edge is pressed in with rotation by a shaft- construction machine and the subsequent casings C are connected in sequence. A guide plate 1 is detachably laid at the upper end edge of this casing C and a screw conveyor 2 is inserted in the guide hole 1a to be vertically and horizontally transferable and suspended by a hook 7 of a crane. In this way, the screw conveyor 2 is horizontally transferred along the guide hole 1a while rotating together with the easing C and the excavating cutter 4b is rotated by a motor 6 to excavate the soil G in the shaft and discharge it from the discharge opening 5b to the outside. Accordingly, the soil G in the shaft can be excavated and discharged to the outside while the casing C is rotated and driven in.

摘要： PROBLEM TO BE SOLVED: To secure the quality of a land reclamation material, minimize water pollution, supply the land reclamation material without problem even if a depth of water changes, and continuously place the land reclamation material.
SOLUTION: An underwater placement device 26 is disposed at the side of the hull 20 of an underwater placement ship 12. The underwater placement device 26 includes a tube body 30 which extends linearly and has a large length corresponding to the longitudinal length of the hull 20. A screw blade 34 is disposed in the tube body 30. The tube body 30 is swung by a wire 2804 so that the front end thereof comes to a position apart a predetermined distance from the bottom. The land reclamation material is supplied from a hopper 32 to the tube body 30, pressed forward in the tube body 30 by the screw blade 34 while being fitted to the tube body, and placed on the bottom. During the maintenance, the screw blade 34 and a motor 36 are slid along the extending direction of the tube body 30 by extending and retracting a hydraulic cylinder 42 to eliminate clogging or the like.

摘要： PROBLEM TO BE SOLVED: To provide a rectangular cross section boring machine capable of efficiently burying a tubular support member of elongated rectangular cross section into the ground. SOLUTION: The greater part of the ground excluding small parts at four corners of rectangular cross section can be excavated because of excavating the ground using a lateral pair of screw shafts partially overlapped with each other from the front view in a jacking direction and rotated in opposite directions to each other. Further, since sediment produced by excavating the ground is discharged by a lateral pair of screw blades in linkage, obstacles such as gravel and rocks buried in the ground can be positively conveyed backward, thereby causing no clogging.

摘要翻译：要解决的问题：提供一种矩形横截面镗床，其能够将具有细长矩形横截面的管状支撑构件有效地埋入地面中。
解决方案：由于在前进方向上从前视图中使用一对侧面部分地重叠的螺旋轴进行挖掘，所以可以挖掘除矩形横截面四角的小部件的大部分地面，彼此相反的方向旋转。此外，由于通过挖掘地面产生的沉积物由连接的一对螺旋叶片排出，所以诸如砾石和埋在地下的岩石之类的障碍物能够被向后传递，从而不会堵塞。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a connecting pin for a male/female joint smoothly insertable in pinholes and capable of positively performing sealing between the male and female joints.
SOLUTION: When the male joint is inserted in the female joint and the tip of the male joint abuts on an elastic packing, both pinholes of the male and female joints are slightly eccentric from each other and put in a partially lapped incongruent state, while the cross-sectional shape of the connecting pin for the male/female joint is of almost elliptic shape insertable in the lapped parts of both pinholes, and the major axis is slightly smaller than the diameter of the pinholes. Further, one end of the connecting pin is provided with a turning head for turning the connecting pin, and a means for stopping the turning of the connecting pin in that position when both pinholes coincide by turning the connecting pin.

摘要： PROBLEM TO BE SOLVED: To provide a rotation assisting device of a rotary press-fitting machine for a columnar member, which does not mar the stability of the rotary press-fitting machine and can smoothly switch to its original rotation transmitting mode when a load imposed on the machine is decreased to such a degree that an existing motor alone can rotate the columnar member, after assistance of rotation by the assisting device.
SOLUTION: The rotary press-fitting machine hangs the columnar member by connecting one end of the columnar member to an output shaft of a rotation driving section inclusive of the motor, which is vertically movably supported by a leader mast. Then the rotation assisting devices of the rotary press-fitting machine for the columnar member, are vertically movably supported by the leader mast. Each rotation assisting device is comprised of a rotary body and an annular rocking body arranged concentrically with each other in an individually rotatable manner; a rocking driving means for rocking the rocking body; a one-way clutch mechanism for connecting the rocking body and the rotary body together at the time of rocking of the rocking body in one direction in order to transmit the rocking to the rotary body but canceling the connection at the time of rocking of the rocking body in the other direction; a vertically moving means for vertically moving the rotation assisting device; and a connecting means for detachably connecting the rotary body to the output shaft of the rotation driving section.

摘要： PROBLEM TO BE SOLVED: To improve workability by supporting the front and rear parts of a base frame by wheels through a supporting frame and making it possible to finely slide the wheels in the axial direction and also change the direction. SOLUTION: When equipping attaching/detaching unit A, Aa for wheels, after the whole device has been supported by outriggers 7, the units A, Aa are fixed to a base frame 1 by respective attaching/detaching arms 15, 15a. Then, the outrigger 7 are contracted and the device is supported by the wheels 14, 14a. Then, the device is transferred to the press-in position of the casing by controlling the steering wheel 28a while dragging a traction rod 31 by a self-propelled vehicle and the forward and rearward position is adjusted. The front and rear support frames 12 for the wheels are infinitesimally and synchronously moved to the right or the left for fine adjustment of the right and left direction of the press-in position. Then, the outrigger 7 is grounded and the units A, Aa are removed from the frame 1 to secure a wide working space. Thereafter, the casing C is held by a chuck 5 and pressed in while rotating. In this way, the device can be easily transferred and the position can be finely adjusted.
