However, this method has the following disadvantages: 1. When the magnetic probe is not parallel to the measuring magnetic ring during the measurement, the measuring personnel will sense the change of the magnetic flux, and the accuracy is poor; If it grows longer, it may be damaged, causing groundwater to enter, affecting measurement, and unable to achieve long-term monitoring

Description
technical field [0001] The invention relates to the field of foundation settlement measurement, in particular to a layered settlement measurement device. Background technique [0002] At present, the domestic method of measuring soil layered settlement is mainly magnetic layered sedimentation instrument, which is made by the principle of magnetic flux change, and is buried at each observation layer by putting a magnetic ring around the settlement tube. When the foundation sinks, the magnetic ring can sink together with the foundation, but the settling tube will not sink. The purpose of measurement is achieved by measuring the relative slip between the magnetic ring and the settling tube. However, this method has the following disadvantages: 1. When the magnetic probe is not parallel to the measuring magnetic ring during the measurement, the measuring personnel will sense the change of the magnetic flux, and the accuracy is poor; If it grows, damage may occur, causing ground...
