A displacement monitoring support device for building foundation pit based on capacitance change

Abstract

The invention relates to the field of building foundation pits, and discloses a displacement monitoring support device for building foundation pits based on capacitance changes. The right side of the baffle is fixedly connected with a cross bar and a connecting plate, and the connecting plate is hinged to Moving bar, the right end of the cross bar is fixedly connected with a support plate, the left side of the support plate is fixedly connected with a first spring, the inside of the support plate is movably connected with a main fixed column, the right side of the support plate is fixedly connected with a mounting frame, the mounting frame The right inner wall 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 stopper. The building foundation pit displacement monitoring support device based on capacitance changes has the effect of moving the baffle to the right after a large displacement of the foundation pit, and pushing the block to the right, which achieves the purpose of automatic detection and reduces the electronic load. The use of components increases the reliability of the device and reduces the cost.

Description

Technical field [0001] The present invention relates to the field of building foundation, in particular to a building foundation supporting means monitoring displacement based on capacitive changes. Background technique [0002] Building Foundation is an important part of building engineering, construction quality foundation has a direct influence on the stability and security of the entire building. [0003] Construction pit after construction is completed, the need for foundation supports protection, to prevent the collapse pit, pit support existing devices at work, can not be prestressed to pit, resulting in achieving the desired effect support base pit sidewall displacement occurs, problems occur building pit size larger error, and a conventional foundation guard, in use, if not cause displacement of the pit excavation device fails, the conventional apparatus the side wall displacement generated by monitoring additional tools need to be measured, not only greatly increase the...

AI Technical Summary

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
