載の地盤沈下測定装置。[Scope of Claim for Utility Model Registration] (1) A pipe main body 11 that always produces a constant overflow and has a pressure receiving part of a water pressure type water level gauge 13 installed on the bottom surface 12 is driven into the bedrock G and the water level 1
4 is always kept at a constant distance K from the ground 16. (2) The pipe main body 11 driven into the bedrock G and the overflow tank 21 constitute a water communication pipe using the thin tube 19, and the overflow pipe 23 is set at a constant height from the ground 16, and the overflow tank 21 is always constant. The overflow tank 21' and the pump 27 are configured to keep the water surface 14 in the overflow tank 21 at a constant distance K from the ground 16, and the water surface 14 is connected to the bottom surface 12 of the pipe body 11. 2. The ground subsidence measuring device according to claim 1, wherein the applied water pressure WP is measured by a hydraulic water level gauge 13 comprising a pressure receiving section 25A and a converter 25. (3) The ground subsidence measuring device according to claim 2, wherein the pump 27 of the overflow device is operated only during measurement, thereby making it an intermittent measuring power saving type. (4) The ground subsidence measuring device according to claim 2, wherein the pump 27 of the overflow device is not necessary, and water is constantly supplied from a water supply or the like through the water inlet 24, and water is drained through the drainage pot 29.
