題点があった。However, requiring two types of detectors, an earth pressure gauge and a water pressure gauge, is costly and requires a large installation area due to the arrangement of the detectors. Generally, since the sum of both earth pressure and water pressure is measured, there is a problem that only effective earth pressure cannot be detected.

できる。According to the present invention, the earth pressure receiving surface receives the difference between the lateral pressure Pa from the earth wall surface and the water pressure Pw of the water flowing into the water storage space, that is, the pressure Pa-Pw, as shown in FIG. As a result, a strain corresponding to this pressure is generated, and the effective earth pressure Pe can be detected by measuring this strain with a sensor. Further, the water pressure receiving surface produces a strain corresponding to the water pressure, and the water pressure Pw can be detected by measuring this strain with a sensor.

The difference between w, that is, the pressure of Pa-Pw, is received, and the strain is measured by the sensor 2 to detect the effective earth pressure Pe. To measure the water pressure Pw. When the lateral pressure is further required, the lateral pressure can be calculated by adding the detected Pe and Pw.
