In the conventional sinking plate, when the square plate is fixed to the ground by the deformation preventing anchor, the sinking pipe protrusion protrudes to the upper portion of the landfill, and the sinking of the grounding sheet can be measured.

However, since the conventional sinking plate is installed so that the sinking rod protecting tube protrudes from the ground surface to the surface of the landfill, the manufacturing cost is increased and it is difficult to install the same, and when the sinking rod protecting tube is separated from the middle, There was a problem.

Particularly, in case of landfilling, it is difficult to install the subsidence plate because the subsurface protection pipe must be connected in the water.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems, and it is an object of the present invention to solve the above problems and to solve the above problems and to provide a landfill- And to provide a submerged settlement plate.

And a carabiner coupled to one of the rings and the other one of the calorimetric plates and the caliper to easily remove the caliper from the calorific plate.

The screw anchor may include a screw portion projecting to the lower portion of the frame and fixed to the underwater cloth, and a handle portion projecting to the upper portion of the frame to rotate and fix the screw portion to the underwater substrate.

The buoy may include a take-up roller for winding up the graduation line, and a winding spring for supporting the take-up roller so that the graduation line is pulled by the elastic force in the direction in which the graduation line is wound on the take-up roller.

The hole plate may include a first plate covering an upper surface of the frame, and a second plate covering a lower surface of the frame.

According to the present invention, since the position of the perforated plate fixed to the underwater floor is measured by the buoy, it is not necessary to provide the downlisting pipe as in the prior art, so that it is easy to manufacture and the manufacturing cost can be reduced.

In addition, a plurality of fluid flow holes are formed in the plate, thereby minimizing the resistance of the fluid, thereby preventing the leakage and position of the plate from being changed.
