Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a foundation pit water depth measuring device. Background Art

[0002] Existing deep foundation pit groundwater level monitoring usually uses portable steel ruler cable water level measuring instruments and levels. The portable steel ruler cable water level measuring instrument is used to manually measure the distance from the top of the water level pipe to the water surface in the water level pipe, and the level is used to manually measure the height difference from the top of the water level pipe to the reference point. Then the change in groundwater level is obtained by calculation. For major deep foundation pit monitoring projects with long periods, high frequencies, and many monitoring points, this monitoring technology will consume more manpower and material resources. At the same time, this manual monitoring technology is greatly affected by the environment, and the manual measurement errors are large and the measurements are inaccurate. Utility Model Content
