All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution:
example 1:
as shown in fig. 1 and 2, a layered settlement monitoring device includes a settlement pipe 1, at least one settlement magnetic ring 2 and at least one displacement sensor 3;
the sedimentation magnetic ring 2 can be arranged outside the sedimentation pipe 1 in a sliding manner along the axis of the sedimentation pipe 1, and the sedimentation magnetic ring 2 is fixed in a layer to be monitored; when the layer to be monitored is settled, the settlement magnetic ring 2 moves synchronously with the layer to be monitored;
the displacement sensor 3 is arranged in the sedimentation pipe 1, and the monitoring end 6 of the displacement sensor 3 is connected with the sedimentation magnetic ring 2 in a non-contact way; when the settlement magnetic ring 2 moves, the monitoring end 6 of the displacement sensor 3 and the settlement magnetic ring 2 move synchronously, and the displacement sensor 3 outputs the settlement of the layer to be monitored in real time and continuously based on the displacement of the monitoring end 6.
The displacement sensor 3 is a linear displacement sensor 3.
The monitoring end 6 of the displacement sensor 3 and the sedimentation magnetic ring 2 are respectively provided with a strong magnetic block, and the monitoring end 6 of the displacement sensor 3 and the sedimentation magnetic ring 2 are mutually attracted through magnetic force.
The displacement sensor 3 comprises a sensor body 4, an induction bar 5 and a monitoring end 6, wherein the monitoring end 6 is a displacement induction code reader (the model of the displacement induction code reader is PM-I-12), the monitoring end 6 is slidably arranged outside the induction bar 5 and synchronously moves along with the sedimentation magnetic ring 2 and reads out the voltage change of the displacement sensor 3, and the sensor body 4 is provided with a demodulation circuit 7 for demodulating the voltage change into displacement output.
The sedimentation magnetic ring 2 is circumferentially and uniformly distributed with a plurality of clamping claws 9, and the sedimentation magnetic ring 2 is fixed in the layer to be monitored through the clamping claws 9.
The sensor body 4 is connected with a collecting instrument through a cable 10.
The working principle is as follows:
the induction bar 5 is equivalent to a resistance wire of a sliding rheostat in the linear displacement sensor 3, the monitoring end 6 is equivalent to a sliding sheet of the sliding rheostat, and the resistance changes when the monitoring end 6 moves, so that the circuit voltage changes (the induction bar 5 is connected with a steady-state direct-current voltage). The structure and principle of the linear displacement sensor 3 are prior art, and are not described herein. And (5) detecting the layer to the soil layer/rock stratum where the measuring point is located.
The sedimentation pipe 1 is arranged in the monitoring hole 11, the sedimentation magnetic ring 2 is sleeved outside the sedimentation pipe 1 in a sliding mode, and the sedimentation magnetic ring 2 is fixed with a soil layer/rock stratum through the clamping claws 9. And after the settling tube 1 and the settling magnetic ring 2 are in place, the displacement sensor 3 is arranged in the settling tube 1. The sensor body 4 of the displacement sensor 3 is connected with a ground acquisition instrument through a cable 10, and the cable 10 plays a role in communication data transmission and also plays a role in fixing the sensor body 4. When the sensor body 4 is fixed, the monitoring end 6 is the displacement induction code reader corresponding to the interior and the exterior of the settlement magnetic ring 2, and the monitoring end 6 is attracted with the settlement magnetic ring 2 through magnetic force.
When the soil layer/rock stratum subsides, subside the magnetic ring 2 with the fixed subsides of soil layer/rock stratum thereupon synchronous subsides. When the settlement magnetic ring 2 moves, the monitoring end 6 is driven to synchronously move downwards through magnetic force, and when the monitoring end 6 moves downwards, the resistance changes, so that the circuit voltage changes. The voltage change is read out when the monitoring end 6 descends, and the voltage change is demodulated into displacement output through the demodulation circuit 7. The displacement output is the settlement of the soil/rock stratum.
When the same monitoring hole 11 has a plurality of measuring points (for example 6), 6 settlement magnetic rings 2 and 6 displacement sensors 3 are arranged corresponding to the measuring points, so that simultaneous measurement of 6 measuring points can be realized.

The linear displacement sensors of various types can be applied to monitoring of layered settlement, so that the automatic monitoring and the monitoring of a plurality of (more than 6) measuring points in one monitoring hole cannot be completely achieved at present; meanwhile, the cost of monitoring the layered settlement can be greatly reduced.
Further, as shown in fig. 1, an induction magnetic ring 8 is arranged outside the monitoring end 6 of the displacement sensor 3, a strong magnetic block is arranged in the induction magnetic ring 8, and the monitoring end 6 of the displacement sensor 3 is connected with the settlement magnetic ring 2 through the induction magnetic ring 8.
