摘要： PROBLEM TO BE SOLVED: To provide a method for constructing a bridge pier capable of making a drastic saving of bar arrangement work. SOLUTION: A bridge pier is integrally built with a plurality of extension steel pipes through placed concrete by erecting a plurality of steel pipes 6, 7, 9, 10 on a foundation 5 including a plurality of supporting piles piled into the ground and a footing supported by a supporting pile in an arrangement corresponding to the bridge pier to be constructed in a plane shape of the bridge pier to be constructed, placing concrete around the plurality of steel pipes, integrating the plurality of steel pipes with each other through the placed concrete, keeping on adding one or more extension steel pipes 14 to the upper end of the plurality of steel pipes, and placing concrete also on the extension steel pipes thus added. The behavior of the steel pipes being structural members or the bridge pier, conventional troublesome bar arrangement work can be drastically simplified and a construction period can be shortened.

摘要： PROBLEM TO BE SOLVED: To increase the bearing power of the ground and the yield strength of a pile in the vertical direction and horizontal direction by the hole wall of a drilled hole placed with underwater concrete with a loading device lifted/lowered in the drilled hole and expanded/shrunk in diameter in the radial direction in the slurry construction method. SOLUTION: A stand pipe 9 is installed on the opening side of a drilled hole 4, mixed slurry 10 is filled, the drilled hole 4 is drilled to the prescribed depth, and a reinforced cage 11 is arranged in the drilled hole 4 after the primary process. A loading device 3 is suspended to the hole bottom side along the outer periphery of the reinforced cage 11, and underwater concrete is placed through a tremie pipe 12. The placed underwater concrete is pressed to the hole wall side by a loading member fitted to the loading device 3 and expandable/shrinkable in the radial direction, and a part of the flow component flows out to the above and below of the loading member. The peripheral natural ground is pressed via the remaining flow component and aggregate and is compacted so that the aggregate bites into the natural ground. The loading member is retreated, the flow component is recovered and solidified by the release of the pressing force, and the sticking force of concrete can be increased.

摘要： PROBLEM TO BE SOLVED: To provide a construction method of a pier capable of further reducing a construction period. SOLUTION: Four ribbed steel pipes 6, 7 and 9 are erected to a footing 5, a plurality of cylindrical single cylinder type precast pipes 15 are so piled up that a tower 21 surrounding the ribbed steel pipes 6 and 7 and a tower 22 surrounding the ribbed steel pipe 9 like the tower 21 are formed, glass type precast pipes 16 forming binoculars are so piled up that both of precast pipes are connected to the upper ends of the towers 21 and 22, and concrete is placed in a concrete pouring space formed among the single cylinder type precast pipes 15, glass type precast pipes 16 and ribbed steel pipes 6 and 7. After the concrete is solidified, the same procedure as that used in the case the towers 21 and 22 are provided to the footing is repeated to extend and form the towers 21 and 22 to construct a pier upward of the towers 21 and 22.

摘要： PROBLEM TO BE SOLVED: To accurately install and connect horizontal reinforcement without requiring skill, eliminate troublesome operations, and enhance the efficiency of connecting work. SOLUTION: This jig has a frame 21, and a jig support member 25 is provided on the frame 21 in such a way as to be freely locked to existing horizontal reinforcement 11 via an engagement support part KS, and the frame 21 is provided with an anti-turnover member 29 in such a way that time member 29 is freely engaged with vertical reinforcement 10. Further, the frame 21 is provided with a plurality of reinforcement support members 23 which are arranged above the jig support member 25 and in the vertical direction along the frame 21, and a reinforcement support part TS on which the horizontal reinforcement 11 can be placed is formed in each reinforcement support member 23.

摘要： PURPOSE: To perform excavating work and muck loading and carrying-out work safely alongside by providing an excavating device and a muck loading device at a frame held in a vertical shaft using a support leg and grippers. CONSTITUTION: A frame 1 having an excavating device 9 and a muck loading device 12 is hung in a vertical shaft 3, and a support leg 4 hung down from the frame 1 is knocked against the bottom part 5 of the vertical shaft 3 to hold the frame 1 to the required height. Three grippers 6 or more radially extended from the frame 1 are pressed to the inner wall 7 of the vertical shaft 3 so as to hold the frame 1 almost at the center of the vertical shaft 3. The vertical shaft 3 is then excavated by the excavating device 9, and a cylindrical protective casing 13 is extended in the vertical shaft 3. A bucket 10 is passed in the protective casing 13 and hung down in the vertical shaft 3. Muck is loaded into the bucket 13 by the muck loading device 12, and the bucket 13 is lifted to carry out the muck. A device can therefore be disassembled into compact, lightweight assembling parts.

摘要： PURPOSE: To prevent powders from entering an indoor space, to keep a field of view as good as possible by which an outside space can be monitored from the indoor space, and to save the trouble of cleaning. CONSTITUTION: A monitoring window 20, installed in a form separating an indoor space SK1 from an outside space SK2 and used in monitoring the space SK2 to be monitored from the indoor space SK1, has a frame 21 and a bar- shaped frame 22, and a communicating space RK shaped to communicate both sides of the bar-shaped frame 22 is formed in the bar-shaped frame 22. A rotary disc 23 is provided on the bar-shaped frame 22 with a driving unit 25 between them, in such a way that within the communicating space RK the disc is driven and rotated about an axis Q2 parallel to the directions of the arrows A, B and relative to the bar-shaped frame 22. In the rotary disc 23, a shielding portion 24a for shielding the communicating space RK about the axis Q2 and in the direction of the arrow C, and a slit 26 through which the outside space SK2 can be seen from the indoor space SK1 in the directions of the arrows A, B, are formed about the axis Q2 of the rotary disc 23 and along the direction of the arrow C.
