Abstract
This utility model discloses an auxiliary device for measuring the elevation difference of deep foundation pits, belonging to the field of leveling surveying. The utility model includes a vertical circle, a rangefinder, and an instrument clamp. The rangefinder is located on the graduated side of the vertical circle. A transmitter / receiver head is located on the right side of the rangefinder. A retainer plug is located on the other side of the vertical circle. A retainer interface is located on one side of the instrument clamp, and a first limiting knob is provided on the retainer interface. The vertical circle is inserted into the retainer interface through the retainer plug and fixed using the first limiting knob, thus connecting the vertical circle and the instrument clamp. A second limiting knob for fixing the level is located on the other side of the instrument clamp. This utility model utilizes a level in conjunction with the added vertical circle and rangefinder to measure the terrain, effectively controlling the bottom elevation of foundation pits during excavation. The measurement method is simple, and the measurement results are highly accurate.
