Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and in particular to a deep foundation pit supporting structure inclination deformation automatic monitoring device and construction method. BACKGROUND

[0002] In engineering construction, the number of deep foundation pit supporting structures is large, and the working conditions are complex. With the increasing safety accidents caused by the instability of deep foundation pit supporting structures, the personal safety of construction personnel is seriously threatened, causing adverse social influence and adverse public opinion on construction. As a major hazard source in construction, effective monitoring and early warning of deep foundation pit are one of the important prerequisites for ensuring construction safety.

[0003] According to the search, the patent with the publication number CN114790730A describes a foundation pit monitoring system, which includes a bottom plate, four groups of support columns fixedly connected to the upper end face of the bottom plate near the four corners, a top plate fixedly connected to the upper end face of the four groups of support columns, the top plate being parallel to and equal in size to the bottom plate, a push handle fixedly connected to the middle of the rear side of the upper end face of the bottom plate, four groups of rollers arranged below the bottom plate, and a monitoring mechanism arranged above the top plate. When the monitoring plate in the detection mechanism touches the foundation pit with a tendency to collapse, the angle will tilt, triggering the L-shaped rod to move to the left. At this time, the material cylinder will spill white powder, and the position of the spilled white powder line will remind the worker of the position of the foundation pit with a tendency to collapse. The thickness of the white powder line also reflects the size of the tendency of the foundation pit at this position to collapse. This device optimizes engineering operations and avoids safety accidents. However, when the foundation pit has a tendency to collapse, the white powder spilled cannot timely alert the worker, and the worker needs to observe continuously to discover the problem. The alarm effect is not ideal, and the alarm speed is not timely. SUMMARY
