Conventionally, in order to measure the amount of subsidence and inclination of the seabed ground 3 when laying a large-scale, deep-water rubble foundation mound to install a breakwater etc. in port construction, a method was used as shown in Figure 4. A sinking plate 2 is erected in advance on the seabed ground 3, a staff 5 is erected on top of the sinking board 2, and the level of the seabed ground 3 is determined by reading the staff 5 from the transit on land 6 and level 7. The amount of subsidence and slope are calculated over time.

There is a drawback, especially in recent years, when building a breakwater or the like in deep water and far offshore from land 6, when laying the rubble foundation mound 1, it is difficult to separate the foundation 5 of the sinking plate 2 erected on the seabed 3. There was a problem in that when measurements were taken at transit level 7 from land 6 at a certain position, the measurement error became large.
