摘要： 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.

摘要： PROBLEM TO BE SOLVED: To provide a method of pouring a mixture of a hardener and earth transported in the form of a plug flow, which is available when a pouring apparatus is arranged on the poured mixture in order to further pour the mixture, and enables to pour the mixture with high working efficiency.
SOLUTION: According to the method, when the pouring of the mixture of the hardener and the earth is carried out by moving the pouring apparatus, the mixture 2 transported in the form of the plug flow is directly poured through the same pouring conduit system in a region more forward than a region to which the pouring device is moved.

摘要： PROBLEM TO BE SOLVED: To provide a control method for the height of placing or scattering out sediment, capable of grasping the influence of inflow or landslide of solidified soil in the process of being placed or scattered out, fixing the measurement direction, and increasing the surveying area to improve the surveying efficiency.
SOLUTION: Two RTK-GPS antennas are mounted on the upper side of a rotatable vertical shaft 2, a laser profiler 4 is set up at the lower end of the vertical shaft 2, and a device for placing or scattering out sediment is provided to the position below the laser profiler 4. Thus, the laser profiler 4 is freely rotated or fixed to control the height of placing and scattering out the sediment.
