[0002] Construction pit monitoring points are specific locations set up during excavation and construction to ensure project safety and monitor the pit's status. These monitoring points are used to monitor key parameters such as pit deformation, stress, water level, and soil stability in real time or periodically. In actual operations, protective devices are typically used to protect these monitoring points.

[0003] Existing protective devices generally use a rectangular frame structure to protect the four sides of the monitoring point. For details, please refer to the Chinese patent announcement number "CN212052681U" disclosed a construction foundation pit monitoring point protection device, which includes a first enclosing panel, a card slot, a first fixed slot, a battery compartment, a lighting lamp, a second enclosing panel, a second fixed slot, a card plate, a battery panel, an electrode sheet, a pull plate, a cover plate, a fixed plate and an observation port.
