Description

Technical Field

[0001] This application relates to the field of foundation settlement detection, and particularly to a portable foundation settlement detection device. Background Art

[0002] Foundation settlement refers to the subsidence of the foundation surface caused by the compaction of foundation soil layers under additional stress. Excessive settlement, especially uneven settlement, can cause buildings to tilt, crack, and become unusable. Existing foundation settlement prediction methods are restricted by the large discrepancy between their assumed conditions and the actual situation, and there are often large differences between the obtained settlement prediction results and the measured settlement values. Further development is needed in the research on foundation settlement prediction methods. Settlement observation is to observe the settlement degree based on the observation points set on the building and the measuring points of the fixed (permanent leveling points), and express it with data. For buildings and structures with more than one floor, observation points should be set as required by the design, including artificial and soil foundations (sand foundations), etc. Settlement observations should be carried out and recorded regularly or according to the construction progress until completion.

[0003] Regarding the above related technologies, the inventor believes that the general settlement detector occupies a large area and is inconvenient to carry, resulting in the need to move the settlement detector when detecting different positions, thus causing inconvenience during detection.

[0004] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to ordinary technicians in this field. Utility Model Content
