摘要： PROBLEM TO BE SOLVED: To measure the mixed amount of metallic fibers simply and correctly at a construction site without breaking a structure, by detecting by means of a receiving coil a magnetic flux generated at a surface of the steel fiber reinforced concrete structure by a transmission coil. SOLUTION: A magnetic flux generated at a transmission coil 3 is changed due to influences of shielding properties of metallic fibers 2 mixed in a steel fiber reinforced concrete(SFRC) structure 1. The magnetic flux change is detected by a receiving coil 4. The mixed amount of metallic fibers can be correctly measured by detecting the magnetic flux change resulting from the metallic fibers mixed in the SFRC structure. Specifically, the magnetic flux generated at a surface of the SFRC structure 1 by the transmission coil 3 is detected by the receiving coil 4 after a phase is adjusted. A line for calibration of the mixed amount of the metallic fibers obtained from peak values through an integration of the detected waveform is calibrated in accordance with conditions of the SFRC structure. Even when a type and an installation method of the metallic fibers differ, the line can be simply corrected in accordance with the conditions.

摘要： PROBLEM TO BE SOLVED: To load and unload a wale bearing member from a post when to-be- embedded pipes are laid and to make it possible to freely adjust its position. SOLUTION: Post construction of sheet pile timbering is so constructed that a wale member for bearing sheet piles arranged to an interior wall of an excavated ditch in the horizontal direction is mounted to prevent the collapse of the excavated ditch. An engaging device 4a for engaging a post 1 with the side of the square wale member 3 is mounted, a pushing lever 6 forming an eccentric curved surface 7 on the front end thereof is mounted to the bottom of the wale bearing member in a turnable manner, and the engaging device 4a is engaged with the end 1a of the sheet pile post. The pushing lever 6 is brought into contact with the inside 1c of the sheet pile post, and the pushing lever is turned to push the wale bearing member against the sheet pipe post to fix. By the constitution, even in a stage where ditch excavation work is carried out, the wale bearing member is slidably fixed to a required position at all times to make it possible to carry out earth retaining work.

摘要： PURPOSE: To promote work efficiency by releasing the straint of an interlocking flange provided to one end of a strut to shorten a strut main body automatically when sewer, etc., are constructed and, at the same time, turning the strut main body with a pivot section provided to the other end of the strut main body as the center. CONSTITUTION: When a sewer is constructed in a ditch, an interlocking plate 25 is slid to the outside with a releasing lever from the ground, and the straint of an interlocking flange provided to the front end of a strut main body 4 is released. Then, the strut 4 is shortened by an interior finished spring and, at the same time, the front end thereof is slipped from a front end strut bracket 28. Then, one pin 10 of a basic end joint device 9 provided to the other end of the strut 4 is pulled out, and the shrut 4 is turned 90 deg. in the horizontal direction with the other pin 10 as the center to form a passage for lowering the pipe. Then, since an amount of projection of basic end strut bracket 16, front end strut bracket 28 and joint device 9 is small, the passage for lowering the pipe is greatly widened. By the constitution, the lowering of the pipe and the loading and unloading of the strut can be easily executed, and the execution can be safely and efficiently carried out from the ground.
