MEASURING CONTROLLER FOR THREE-DIMENSIONAL POSITION AND ATTITUDE OF RUBBLE-MOUND FORMER IN WATER

摘要

PURPOSE:To control the three-dimensional position and attitude of a rubble- mound former by providing a detector for moving length of the former, a detector for horizontal angles, a detector for water pressure, detector for direction, a detector for inclination angles, an arithmetic memory device to receive measured values, and a displayer. CONSTITUTION:On a base position 2, a length detector 5 serving as a reference point for measurement of position on the horizontal face of a former 1 and measuring the length of sending a wire 3 is provided. Horizontal angle alpha is measured by a horizontal angle detector 6, and water pressures in given places are detected by water pressure detectors 7 and 8. Direction angle beta to a planned advancing the line L is measured by a direction detector 9, and the inclination angles of the former 1 to the horizontal plane are measured by an inclination angle detector 10. These data are put in an arithmetic memory device. Rubble-mound in water can thus be well formed without losses of labor and time for releveling work, etc., and with enhanced efficiency of operations.
