MEASURING INSTRUMENT FOR INCLINOMETER TYPE BLOCK INSTALLATION FINISH SHAPE

摘要

PURPOSE:To easily grasp the finish shape of a block group from an on-water part by laying a measurement belt which is formed by coupling plural links by universal joints in contact with the wave elimination surface of a deformed block, and measuring and analyzing the tilt angle of each link. CONSTITUTION:Many links 2 which are provided with universal joints 1 at both ends are connected to constitute the measurement belt 10. Each joint 1 is constituted by embedding magnet rubber 3 in the shaft art of a bearing and fitting a magnetic sensor 4 to the holder part of the bearing and can detect the relative angles of the links 2. Further, the measurement belt 10 is prevented from falling in between blocks B by connecting three link lateral links 5 successively. This measurement belt 10 is laid on the wave elimination surface of the deformed block B in contact by a holding device (not shown in figure) and the output of the magnetic sensor 4 is inputted. Then specific arithmetic operation is performed to display the finish shape as a figure.
