It mainly consists of a settlement pipe, multiple layered settlement sensors, a data acquisition and processing unit, a wireless transmission module and other parts.

[0003] In the monitoring environment, fine particulate matters such as sediment are likely to scatter everywhere due to natural factors or construction reasons. If the settlement pipe has no protective cover, these sundries may not only affect the movement of the magnetic ring, but also interfere with the measurement signal, bringing difficulties to data acquisition and analysis, and increasing the maintenance and replacement costs of the monitoring device. Therefore, it is necessary to design an automatic monitoring device for layered settlement of soft foundation monitoring with a protective device to solve the above problems. Content of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide an automatic monitoring device for layered settlement of soft foundation monitoring. In this scheme, the protective cover body is arranged outside the inner pipe, which can provide a relatively stable environment for the monitoring components inside the inner pipe, reduce the interference of external factors on them, enable components such as the magnetic ring assembly to more accurately reflect the settlement changes of the soil layer, and then improve the accuracy and reliability of the measurement data, which is helpful for more accurately analyzing and evaluating the foundation settlement situation.

[0005] To solve the above problems, the utility model adopts the following technical scheme.

[0006] An automatic monitoring device for layered settlement of soft foundation monitoring, including an inner pipe arranged in the ground inner hole, a plurality of magnetic ring assemblies are arranged on the outer end of the inner pipe from top to bottom, a support upper pipe sleeve located outside the inner pipe is arranged at the upper end of the ground inner hole, a plurality of positioning holes are opened at the upper end of the support upper pipe sleeve, vertical rods are installed at the inner ends of the positioning holes, the upper ends of the plurality of vertical rods are movably connected with a protective cover body, the protective cover body is located outside the inner pipe, double-layer inner grooves are opened on the inner side wall of the vertical rod, convex cross bars are symmetrically and fixedly connected to the left and right ends of the vertical rod, the convex cross bars extend into the double-layer inner grooves, and the double-layer inner grooves and the convex cross bars are in a cross-overlapping state, and flat grooves are symmetrically opened at the upper and lower ends of the convex cross bar.

[0007] Furthermore, a pair of spring members are fixedly connected to the inner side wall of the flat groove, and outer convex cross plates are fixedly connected to the outer ends of the two spring members.

[0008] Further, a wear-resistant outer layer is fixedly connected to the outer side wall of the convex cross plate, and the convex cross plate is in contact with the upper and lower inner walls of the double-layer inner groove.

[0009] Further, a number of fillers are filled at the inner end of the ground inner hole, and the number of fillers is located outside the inner pipe.

[0010] Further, a protruding rotating rod member is fixedly connected to the upper end of the vertical rod, and the protruding rotating rod member penetrates to a position above the protective cover body.
