摘要： PROBLEM TO BE SOLVED: To provide a stable supporting force in any construction conditions.
SOLUTION: In this rotational penetration pile 20, a spiral drill 10 is coaxially attached to the bottom end 24 of a cylindrical pile body 23. The drill 10 includes a supporting part 11 axially extending with a same spiral diameter r1 and a drill part 12 formed at the end of the supporting part 11 and having a spiral diameter r2 gradually decreasing toward the end. The spiral diameter r1 of the supporting part 11 is equal to or lower than the maximum diameter R of the pile body 23. The outer shape of the supporting part 11 and the drill part 12 is square in any cross section perpendicular to the axis. Since the spiral diameter of the drill 10 is equal to or lower than the maximum diameter R of the pile body 23, the peripheral ground is hardly released, and a stable peripheral surface frictional force can be secured. Since the cross section of the drill is square, a pressure bulb part is produced at the root of the pile, and a predetermined supporting force can be provided. Since the drill 10 is divided into the supporting part 11 and the drill part 12, the drill can be smoothly penetrated into the ground while maintaining the supporting force of the pile.

摘要翻译：要解决的问题：在任何施工条件下提供稳定的支撑力。解决方案：在该旋转贯穿桩20中，螺旋钻10同轴地连接到圆柱形桩体23的底端24.钻头10包括以相同的螺旋直径r1轴向延伸的支撑部分11和钻头部分12形成在支撑部分11的端部并且具有朝向端部逐渐减小的螺旋形直径r2。支撑部11的螺旋直径r1等于或低于桩体23的最大直径R.支撑部11和钻头部12的外形在垂直于轴线的任何横截面中是正方形的。由于钻头10的螺旋直径等于或低于桩体23的最大直径R，所以周边地面几乎不释放，并且可以确保稳定的周面摩擦力。由于钻头的横截面是正方形的，所以在桩的根部处产生压力灯泡部分，并且可以提供预定的支撑力。由于钻头10被分成支撑部分11和钻头部分12，钻头可以平稳地穿透到地面中同时保持桩的支撑力。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To easily and securely expand a diameter of a lock ring regardless of a diameter of a pipe.SOLUTION: The lock ring 4 having a separation part 3 formed on the periphery is provided on a receiving part of a receiving pipe body 1. A diameter expanding jig 11 having a tapered part 12 on the tip is inserted into the inner periphery of the lock ring 4. Due to the insertion, both the tapered part 5 and the tapered part 12 of the inner periphery of the lock ring 4 and the diameter expanding jig 11 are brought into contact with each other to expand the diameter of the lock ring 4. After expansion of the diameter, both ends of the separation part 3 are brought into contact with a stopper 8 to draw the diameter expanding jig 11 while maintaining the expanded diameter of the lock ring 4. The outer diameter of the diameter expanding jig 11 is appropriately determined according to an inner diameter of the pipe body 1, so that the jig is applicable regardless of diameter of the pipe body 1. While the diameter of the lock ring 4 is expanded, an insertion pipe body 17 can be smoothly inserted into the receiving pipe body 1.

摘要： PROBLEM TO BE SOLVED: To easily remove rust stuck to the inside face of a branch pipe part in a water pipe channel without using a device with a complicated constitution, and also to exhaust the rust to the outside.
SOLUTION: A branch pipe cleaning device is composed of: a pipe shaft 1 whose tip is integrated with a removing blade 2; and an exhaust port 3 bored in the outer face of the pipe shaft 1. The device is attached to a branch pipe part p by a connection member 4 externally fitted to the pipe shaft 1 in a water-stopped state, and lowers while rotating an operational handle 5 at the rear edge of the pipe shaft 1, so as to crush rust at the inner face of the branch pipe part p. After that, the exhaust port 3 is opened, and the rust is exhausted to the outside. Compared with the conventional ones in which a cleaning means and a rust exhaust means are separated, its operability is remarkably improved.

摘要： PROBLEM TO BE SOLVED: To simply perform a connection work of tubular bodies without damaging. SOLUTION: The plug of one tubular body 1b is inserted into the socket of the other tubular body 1a to form a through-hole 2 on the side surfaces of both tubular bodies 1a, 1b. A bolt 5, wherein the outer circumferential tapered surface 3 is formed on the outer circumference thereof and a threaded part 4 is formed at both ends thereof, is inserted into the through-hole 2. After the insertion of the bolt 5, a spacer 7, wherein the inner circumferential tapered surface 6 is formed on the inner circumference thereof, is fitted to both ends thereof in the direction, making both tapered surfaces 3, 6 abutting on each other. Furthermore, a nut 8 is screwed into the threaded parts 4, 4 at both ends of the bolt 5 to cause the bolt 5 and both tapered surfaces 3, 6 of the spacer 7, and the inner surface of the through-hole 2 and the outer circumferential surface of the space 7 to be brought into pressure contact with each other, ensuring connection of both tubular bodies 1a, 1b. The diameter of the bolt 5 is smaller than the inner diameter of the through-hole 2, and the insertion of the bolt 5 into the through-hole can be smoothly executed without damaging the tubular bodies, with no risk of damaging the tubular bodies 1a, 1b caused by a wrong impact.

摘要： PROBLEM TO BE SOLVED: To rapidly bury a rotary penetration pile by preventing excavation efficiency from being decreased by sediment and boulder stones during excavation.
SOLUTION: A first tapered portion 3, the shaft diameter of which becomes smaller toward its leading end, is formed in a pile body 2; and a second tapered portion 4, which has a lager taper angle while making the shaft diameter continue between the first and second tapered portions and the shaft diameter of which becomes smaller toward its leading end, is formed on the leading end side of the first tapered portion. A spiral rotor blade 6 is formed on the first tapered portion, and a drilling blade 7 is formed on the second tapered portion. When a ground surface is excavated by means of the rotary penetration pile, the excavation of the ground surface is not inhibited by the boulder stones because the boulder stones in the sediment are removed from the vicinity of the leading end of the rotor blade by abutting on the drilling blade and the second tapered portion. Additionally, since the sediment between the blades is partially pushed out to the outside in the radial direction of a shaft center by the first tapered portion, a section between the blades is hardly clogged with the sediment, so as to prevent a decrease in the excavation efficiency.

摘要： PROBLEM TO BE SOLVED: To prevent the breakage of a conductive member during expanding and bending a joint portion. SOLUTION: Metal pipe bodies 1, 1 connected to each other via the joint portion 2 are embedded in a sheath pipe P via a filler G, the pipe bodies 1, 1 with the joint portion 2 therebetween are linked to each other via a conductor 12 so that the pipe bodies 1, 1 are conducted with each other, and a movable portion 20 is provided in the conductor 12 for allowing expansion. Thus, when the joint portion 2 is expanded and bent, the conductor 12 can be moved following the movement of the pipe body 1, and so its breakage is prevented. Around the movable portion 20, a protecting member 21 is provided which is formed of a foamed resin molding in close contact with the movable portion 20. Other portions than the movable portion 20 are covered with a protecting member 22 which is formed of a resin protecting pipe, to isolate the conductor 12 from the filler G around the pipe body 1. When the pipe body 1 and the protecting member 21 are moved relative to the filler G with the expansion of the joint portion 2, a void to the filler G therearound is secured to avoid barrier in moving the movable portion 20.

摘要： PROBLEM TO BE SOLVED: To secure the sufficient circulation area and reduce the insertion power of a new pipe. SOLUTION: Spheres 3 are laid down in a buried sheath pipe P' and the new pipe P is placed on the spheres 3 which are inserted into the above sheath pipe P'. The new pipe P is moved axially in the sheath pipe P' by rotating the above sphere 3 and a new pipe channel is created in the sheathe pipe P' by connecting an insertion nozzle of the new pipe P with a socket nozzle of a preceding new pipe one by one. At this time, the insertion power of the new pipe P can be reduced because the new pipe P moves in the sheathe pipe with the small resistance by rotating the sphere. Also, the diameter (size) of the sphere 3 which is placed in the sheath pipe P' becomes the gap between the sheath pipe P' and the new pipe P. Thereby, the gap between the new pipe P and the sheath pipe P' can be lessened and the sufficient circulation area can be secured by the inserted new pipe P. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：确保足够的循环面积并降低新管道的插入力。解决方案：将球体3放置在掩埋套管P'中，并且将新管P放置在插入上述护套管P'中的球体3上。新管P通过旋转上述球体3而在鞘管P'中轴向移动，并且通过将新管P的插入喷嘴与前一新的插座喷嘴相连接而在鞘管P'中形成新的管道管一个一个。此时，由于新管P通过旋转球体而以较小的阻力在鞘管中移动，所以可以减小新管P的插入力。此外，放置在鞘管P'中的球体3的直径（尺寸）成为护套管P'与新管P之间的间隙。由此，新管P与鞘管P'之间的间隙，可以减轻并且通过插入的新管道P可以确保足够的循环面积。版权所有（C）2007，JPO＆INPIT
