[0001] The utility model relates to the technical field of foundation pit displacement monitoring, in particular to a foundation pit displacement monitoring device. Background Art

[0002] The foundation pit is an earth pit excavated at the foundation design position according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be decided based on geological and hydrological data and the conditions of nearby buildings on site, and waterproofing and drainage work should be done well. If the excavation is not deep, the side slope can be used to stabilize the earth slope, and the slope size is determined according to relevant construction regulations.

[0003] After the foundation pit is excavated, it takes a long time to pour concrete. Therefore, the change in the position of the foundation pit affects whether the foundation pit is safe.

Engineers use measuring instruments to observe one side for a period of time. In this way, the change in displacement cannot be discovered in time, or the displacement change of the foundation pit edge is large and cannot be discovered and remedied in time, resulting in serious safety accidents. For this reason, a foundation pit displacement monitoring device is proposed. Utility Model Content
