Example Embodiment
[0038] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary, and is not intended to limit the scope of the present invention and its application.
[0039] figure 1 It is a schematic diagram of the measurement positioning unit. figure 1 Among them, the measurement positioning unit is composed of an inclinometer tube 1, a magnetic ring 2, a measuring rod 3, a lifting device 4, and a limit switch 10. The inclinometer tube 1 and the magnetic ring 2 are embedded in the subgrade to be measured in advance by drilling. The magnetic ring 2 will be buried in the observation points of different depths under the subgrade, and the holes will be sealed with expansive soil. The magnetic ring will settle synchronously with the ground.
[0040] The lifting device 4 is composed of a motor 401, a reel 402, a pulley 403, a cable or a safety rope 404. The cable is connected ...
