Description

Technical Field

[0001] The utility model relates to the technical field of building construction detection, in particular to an axial force monitoring device based on foundation pit monitoring. Background Art

[0002] The foundation pit generally adopts a support structure of continuous wall plus steel support, and the support axial force is a must-measure item. Support axial force monitoring, monitoring the changes of support axial force during the construction of the foundation pit, requires the use of an axial force monitoring device.

[0003] In the prior art, during the use of the axial force monitoring device, it is necessary to weld the mounting frame on the outside of the axial force monitoring device to the steel support frame. After the mounting frame is welded, the axial force meter is placed in the mounting frame, and then the bolts are rotated and the axial force meter is squeezed and fixed by matching tools. The contact area between the extruded end of the bolt and the axial force meter is small, resulting in poor clamping effect and low stability of the axial force meter. At the same time, over-tightening the bolts may cause deformation and damage to the axial force meter, which cannot meet the use requirements. For this reason, we propose an axial force monitoring device based on foundation pit monitoring to solve the above problems. Utility Model Content
