Background
The soft soil foundation has the characteristics of high water content, high porosity ratio, high compressibility, low permeability, low strength and the like, consolidation settlement is easily generated under the action of an upper load, and the prediction and control of settlement deformation of the soft soil foundation in engineering become key problems. The layered settlement monitoring is an effective method for measuring the settlement amount, the settlement speed and the thickness of a compression layer of each layered soil in a foundation, and the operation is to sleeve a magnetic ring on a settlement pipe, bury the magnetic ring into a preset depth together in a drilling mode, and detect the position of the magnetic ring through a detection head to determine the settlement value. The traditional layered settlement magnetic ring consists of a magnetic ring and three spring pieces with included angles of 120 degrees, so that the spring pieces are contacted with a buried soil body and are settled together with the buried soil body, but the magnetic ring is easy to separate from the soil body to settle because the contact area of the spring pieces and the soil body is too small, later, researchers propose that three clamping bodies are uniformly distributed at the upper end and the lower end outside the magnetic ring respectively, the three clamping bodies at the upper end and the lower end are respectively bound around a settlement pipe during downward placement, the clamping bodies are scattered to a preset position after a binding material is dissolved and are settled synchronously with the soil body, but the magnetic ring cannot be accurately placed to the preset position because the dissolving speed of the binding material is uncertain; and the contact area between the clamping body and the soil body is small, and the clamping body cannot be well settled synchronously with the surrounding soil body. The rotary blade type settlement ring also discloses a method for controlling the opening of the blades by adopting the matching of the steel wire and the spring, but after the steel wire is placed under the ground for dozens of meters along with the settlement pipe, the steel wire is difficult to pull out, the soil settlement cannot be accurately judged under the condition that the blades are not opened, and the repeated monitoring cannot be carried out after the steel wire is pulled out. In conclusion, the traditional layered settlement magnetic ring is difficult to meet the settlement monitoring requirement.
