The studies in the above fields often employ a model test method.
The model test method is divided into a large-scale test and a centrifugal model test, wherein the centrifugal model test can reproduce the stress state of a building to a great extent due to the fact that the model box is arranged in the centrifugal machine, but the test equipment is easy to millions, and the test cost is high.

In addition, the model test researches the monitored objects and the quantity are complex and changeable, and under extreme conditions, the displacement measurement of more than 10 positions of the researched objects is needed, and how to place a plurality of sensors is important to the smooth performance of the test.
It is important to determine how to use the simplest means to achieve an adjustable underwater position monitoring device.

A reinforcing fixing plate 125 is provided between the pair of hollow iron frame outer sleeve units 121 and/or between the pair of hollow iron frame embedded units 122, and both ends of the reinforcing fixing plate 125 are respectively fixed to the oppositely arranged hollow iron frame outer sleeve units 121 and/or hollow iron frame embedded units 122 via M6 screws 126.
