Zusammenfassung:	The utility model relates to a working base point monitoring device which comprises a working base point body. The bottom end of the measuring rod extends into the ground by at least 20 meters, and the bottom of the working base point body is higher than the top end of the measuring rod; and the distance detection mechanism is arranged at the bottom of the working base point body and is used for detecting the distance from the bottom of the working base point body to the top end of the measuring rod. According to the utility model, the measuring rod is arranged, the bottom of the measuring rod extends to at least 20 meters below the ground, the stratum 20 meters below the ground surface is stable, the settlement of the stratum can be neglected, the elevation of the top end of the measuring rod is unchanged, and the detection value of the distance detection mechanism reflects the elevation change of the working base point body, so that a worker can conveniently know the elevation change of the working base poi
