The impact force measuring device

PROBLEM TO BE SOLVED: To provide an impact force measurement device that can be used for determining an impact force when waste disposal cast into the sea sinks and strikes against the sea bottom.SOLUTION: An impact force measuring device 1, to which a cord 71 has been connected in order to pull out the device in an inspected cast zone of waste disposal, is cast into the sea. When the impact force measuring device 1 reaches the sea bottom, this device 1 is pulled up with the cord 71 provided for pulling it up. A memory card, on which measurement outputs from an impact measurement triaxial acceleration sensor, position information triaxial acceleration sensor, and triaxial gyro sensor provided in the impact force measuring device 1 have been recorded in time series, is removed. Using a computer system prepared separately, information about, for example, impact force applied to the sea bottom by the impact measuring device 1 and the place where the impact force measuring device 1 has reached the sea bottom, is derived.
