摘要： PURPOSE:To eliminate the influence of oscillation of a ship by extending a cord body fixed to an underwater structure to a pulley fitted to an on-ship support rack and fitting a reflecting prism for a light wave range distance meter to the vertical part of the cord body over the surface of water. CONSTITUTION:The pulley 3 is fitted to the support rack 2 stood on the ship 1 and a piano wire 5 whose one end is coupled with an underwater beam 4 on the bottom surface of the sea is extended. A weight 7 is coupled with the other end of the piano wire 5 and applied with a constant tensile force. Further, the reflecting prism 6 is fitted to the vertical part of the piano wire 5 on the sea surface as a target for the light wave distance meter 8. This distance meter 8 collimates the prism 6 to find the oblique distance (d) between KL and TL and a perpendicular angle alpha, thereby finding the specific height difference h1. Then, the specific height difference h2 between the reverse surface of the underwater beam 4 and DL is found from this value h1 and known l1 and l2, and H and H1.

摘要： PURPOSE:To provide a muddy water treatment system which surely prevents water pollution of a river. CONSTITUTION:In a muddy water treatment system in which muddy water generated in water utilization facility 1 is treated and the treated water 4 is discharged to a river 3 through a discharge channel 7, the water quality of water 4 before discharge is measured with a treated water quality measuring instrument 16, the values of water quality upstream 3a and downstream 3c from the channel 7 in the river 3 are measured with river water quality measuring instruments 12a, 12c. The water quality signals of the instruments 16, 12a, 12c are converted into the water quality signals of a standard unit system by a programmable logic controller 10 to be stored in a memory 9, the water quality signals in the memory 9 are monitored by a controller 4, and the channel 7 is opened to discharge the water 4 when the water quality is within a specified drainage standard. The upstream water quality and the downstream water quality in the memory 9 are monitored when the channel 7 is opened, and the channel 7 is closed when the difference between the upstream water quality and the downstream water quality becomes a specified tolerance value or more.
