Foundation pit slope gradient detection device

The utility model discloses a foundation pit slope gradient detection device, which relates to the technical field of foundation pit detection and comprises a fixed block, a cross rod and a vertical rod, and the cross rod is fixedly arranged on one side of the fixed block. The transverse rod is placed on the side slope, the vertical rod and the top block are taken out of the containing groove and the square groove, the vertical rod and the top block are erected, observation is conducted through bubble liquid in the glass horizontal cylinder, the vertical rod and the top block are in a vertical state, when the vertical rod and the top block are rotated, the vertical rod drives the extending rod to rotate in the sliding groove, and when the vertical rod is vertical, the extending rod is driven to rotate in the sliding groove. The angle scale pointed by the extension rod and the pointer is the angle between the vertical rod and the cross rod, the gradient is the angle obtained by subtracting ...
