Beschreibung
Zusammenfassung:	The utility model relates to the technical field of engineering measurement, and discloses a building foundation engineering measuring instrument with a protection structure, which comprises a bottom plate, a supporting column is fixedly arranged on the upper surface of the bottom plate, a measuring instrument body is fixedly arranged on the upper surface of the supporting column, and four fixing blocks are fixedly arranged on the upper surface of the bottom plate. Small bearings are fixedly installed on the four fixing blocks, a protection structure is arranged on the upper portion of the bottom plate, and a fixing limiting structure is arranged on the upper portion of the bottom plate. The connecting rod is rotated to drive the left protective shell and the right protective shell to rotate by 90 degrees, so that the left protective shell and the right protective shell are combined, and the measuring instrument body is protected; the pulling block is pulled towards one side of the limiting spring, the L-shap
