Alarm device for measuring displacement of foundation pit

Abstract

The invention discloses an alarm device for measuring displacement of a foundation pit, and belongs to the technical field of foundation pit measurement. According to the technical scheme, the alarm device is characterized by comprising a top plate and an intelligent control system, the top of the top plate is fixedly connected with a shielding frame, a motor is fixedly connected to the position, located in an inner cavity of the shielding frame, on the left side of the top of the top plate through a supporting seat, an output shaft of the motor is fixedly connected with a threaded rod, the other end of the threaded rod is movably connected with the inner wall of the shielding frame through a bearing, and the surface of the threaded rod is in threaded connection with a threaded sleeve. The problems that in an existing alarm device for measuring displacement of a foundation pit, due to the fact that the structure mostly adopts bolt fixing or welding fixing, adjusting is inconvenient during use, consequently, the situation that monitoring is not comprehensive is prone to happening in the later-period monitoring process, errors are prone to being generated, manual measurement work is mostly adopted, inconvenience is brought to manual measurement work under factors such as weather, and consequently the monitoring accuracy of the alarm device for measuring the displacement of the foundation pit is lowered, and the working efficiency of the alarm device is lowered are solved.

Description

Technical field [0001] The present invention relates to the field of measuring technology foundation, in particular, it relates to an alarm device for measuring the displacement of the foundation. Background technique [0002] Pit refers to the ground for the foundation and basement of the building carried out the excavation of the construction space, temporary works belonging to the foundation, its role is to provide a space for the foundation of masonry work to be carried out according to the design specified location. [0003] Excavation to a growing number of large, deep direction, because of the complexity of the excavation itself, so you need to get data deformed by excavation monitoring, appropriate reference for the design and construction optimize the construction parameters, in order to achieve information of construction, foundation pit to avoid structural collapse caused huge human and economic losses, and the correct application of measurement techniques, in particul...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides an alarm device for measuring foundation pit displacement, which aims to solve the problem that the existing alarm device for measuring foundation pit displacement is mostly fixed by bolts or welding, which is inconvenient to adjust during use, resulting in incomplete monitoring during later monitoring. , easy to produce errors, and most of them use manual measurement work, which will bring inconvenience to manual measurement work under weather and other factors, thereby reducing the monitoring accuracy of the foundation pit displacement alarm device and reducing its work efficiency.
