Abstract

The application discloses a foundation pit displacement detection device and a monitoring method thereof, which comprises a base, a prism, a rotating frame for bearing and rotating the prism, and a quick locking mechanism for quickly disassembling the prism from the rotating frame. The quick locking mechanism is arranged between the prism and the rotating frame to realize quick disassembly of the prism from the rotating frame, so that a construction worker can conveniently install a new prism and remove a damaged prism, and then the angle of the prism is adjusted by the rotating frame to cooperate with a total station outside the foundation pit and a reference point prism to perform measurement and calculation. In this way, the prism can be replaced conveniently, and the engineering progress is improved.
