Abstract

PURPOSE:To accurately measure the position of a submarine buried body by lowering the sensor rack provided with a sensor on the bottom of the sea along a guide rope, adjusting the position of the rack by moving a davit over confirmation through a radio wave position measuring instrument antenna provided to a davit coupling bar, and then seating it on the bottom of the sea. CONSTITUTION:The guide rope 13 of an anchor block 22 is lowered on the bottom 1 of the sea through the operation of the winch 9 of the block 22 of a measurement ship 11 and after front and rear blocks are seated on the bottom 1 of the sea, the blocks are seated on the bottom 1 of the sea at the same time at intervals of 0.5m to maintain a guide rope interval L. Then the sensor rack 3 is lowered on the bottom 1 of the sea by a rope 14 along the guide rope 13 through the operation of the winch 8 and the ropes 13 and 14 are loosened. Further, a sensor cable 15 connected to a magnetic sensor 4 is elevated and lowered by a cable winding device 16. The position of a submarine tube 2 is measured after the sensor rack 3 is set, and if there is a deviation between the center part 3A of the sensor rack 3 and the center line C of the submarine tube 2, the center part 3A is moved until it meets the center line C and a measurement is taken again.
