Description

Technical Field

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

[0002] Foundation pit dewatering refers to the dewatering work done when the groundwater level is higher than the bottom of the excavation during foundation pit excavation. This is to ensure that the foundation pit can be constructed under dry conditions and to prevent slope instability, foundation sand flow, pit bottom uplift, pit bottom pipe gushing and a decrease in foundation bearing capacity. During the foundation pit construction process, the water level inside the foundation pit needs to be monitored, which requires the use of a foundation pit dewatering monitoring device.

[0003] Most existing monitoring methods are to install cameras at high places around the foundation pit for monitoring. Since the camera's shooting angle is a bird's-eye view, it is difficult to judge the water level in the foundation pit from the picture it takes, resulting in poor monitoring effect on foundation pit dewatering. Therefore, a foundation pit dewatering monitoring device is now proposed. Utility Model Content
