Description

Technical Field

[0001] The utility model relates to the technical field of monitoring devices, in particular to a deep foundation pit support deformation measurement monitoring device. Background Art

[0002] The monitoring device is a key device used to ensure the safety of deep foundation pit projects. It can monitor the displacement, inclination and settlement of the foundation pit wall in real time, and promptly detect potential structural instability problems, thereby avoiding the occurrence of foundation pit collapse accidents.

[0003] Common monitoring devices generally use guide tubes to fix and guide certain components of the monitoring device to ensure its stability and accuracy. Sensors and other monitoring elements are fixed at the far end of the guide tubes through mounting plates. The sensors are responsible for capturing tiny changes in the foundation pit and support structure. These data are collected through data acquisition units, and then transmitted to the monitoring center by communication modules. Analysis software processes and interprets the data.

[0004] The volume of deep foundation pit support is large and needs to be supported by anchor rods. However, due to the large number of anchor rods, the monitoring device is generally connected to one of the anchor rods through a traction rope, and the deformation of the deep foundation pit support is measured by the extended length of the traction rope. When other anchor rods tilt, the traction rope cannot be pulled immediately, and the potential hazards of the deep foundation pit support cannot be discovered in time, resulting in the occurrence of foundation pit collapse accidents.
