Problems solved by technology

[0003] After the construction of the foundation pit is completed, the foundation pit needs to be supported and protected to prevent the foundation pit from collapsing. The existing foundation pit support device cannot apply prestress to the foundation pit when it is working, resulting in the support effect not reaching expectations. The displacement of the side wall of the pit caused a large error in the size of the building foundation pit, and the existing protection device for the foundation pit, when in use, if the displacement of the foundation pit causes the support device to fail, the existing device cannot correct the foundation pit. Monitoring the displacement generated by the side wall requires additional tools for measurement, which not only greatly increases the construction cost, but also easily reduces the construction efficiency and increases the workload of the workers when installing multiple devices during use, resulting in the inability to complete the construction work normally

Abstract

The invention relates to the field of building foundation pit, and discloses a building foundation pit displacement monitoring and supporting device based on capacitance change. The right side of a baffle is fixedly connected with a cross rod and a connecting plate, the connecting plate is hinged with a moving rod through a connecting rod, the right end of the cross rod is fixedly connected with asupporting plate, the left end of the supporting plate is fixedly connected with a first spring, the interior of the supporting plate is movably connected with a main fixing column, the right side ofthe supporting plate is fixedly connected with a mounting frame, the right inner wall of the mounting frame is fixedly connected with a second spring, the left end of the second spring is fixedly connected with a pressing plate, the right side of the pressing plate is fixedly connected with a push rod, and the right end of the push rod is fixedly connected with a stop block. According to the building foundation pit displacement monitoring and supporting device based on the capacitance change, after the large displacement of a foundation pit occurs, the baffle moves rightwards, and the stop block is pushed to the right, so that the purpose of automatic detection is achieved, the use of an electronic component is reduced, the reliability of the device is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of building foundation pits, in particular to a displacement monitoring and supporting device for building foundation pits based on capacitance changes. Background technique [0002] The construction foundation pit is one of the important contents in the construction project, and the construction quality of the foundation pit has a direct impact on the stability and safety of the whole building. [0003] After the construction of the foundation pit is completed, the foundation pit needs to be supported and protected to prevent the foundation pit from collapsing. The existing foundation pit support device cannot apply prestress to the foundation pit during operation, resulting in the support effect not reaching expectations. The side wall of the pit is displaced, and there is a problem that the size of the building foundation pit has a large error, and the existing foundation pit protection device, when in use, if the ...
