Abstract

PURPOSE: To enable automatic measurement by calculating, through the intermediary of an arithmetic operator, the operational depth from a signal of the extended length of a wire suspending an underwater civil engineering mechine, a signal of the position of the bottom of a ship in relation to the suspension reference position, a signal of the distance between the construction reference plane and a seabed, and output signals of the depth signal and the draft signal that pass low- pass filters.
CONSTITUTION: The lowering distance X of the wire 4 suspending an underwater soft ground improving device 3 is detected by a gage 16 of extended length of the wire and sent to the operator 19. The signal regarding the distance Y0 between the reference plane (b) and the seabed is outputted from the 2nd setter 17 to the operator 19. The signal regarding the height Z0 of the suspension reference position from the bottom of the ship is sent from the 1st setter 18 to the operator 19. Water depth Y and draft Z are detected by the 2nd water-depth gage 12 and the 1st water- depth gage 15 respectively, sent to the operator 19 through amplifiers 7 and 9 and low-pass filters 8 and 10, there the improvement depth Q=Y-(Y-Y0)-(Z0-Z) is calculated and this is indicated in an indicator 20 and a recorder 21. In this way, the imprevement depth Q can be measured continuously and automatically.
