Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a device for detecting deformation of foundation pit support. Background Technology

[0002] Foundation pit support is a set of measures to support, reinforce and protect the side walls and surrounding environment of the foundation pit in order to ensure the safety of underground structure construction and the surrounding environment. Foundation pit support is a temporary support and can also effectively prevent the leakage of groundwater.

[0003] Existing technology involves creating multiple through holes in the columns supporting the foundation pit and then setting grooves in the through holes. When the push plate on the outside of the through hole is squeezed and moved, it causes the slider in the groove to move and hit a switch, causing the alarm on the column to light up and sound an alarm. However, this technology can only detect the situation on the side of the column. The danger of foundation pit collapse mainly comes from above the foundation pit. In addition, the side baffle is easily damaged by falling rocks from above, making it impossible to detect and the detection effect is limited. It is also difficult to distinguish whether the cause is deformation of the foundation pit support. After searching, it was found that the technical solution provided by the utility model with application number CN202120102293.X also has the above problems. Summary of the Invention
