[0055] working principle:
[0056] First, drill a fixed hole 02 on the ground, so that the fixed hole 02 continues to extend downward until the surface of the bearing soil layer 03 is exposed, and then punch a fixed installation hole 04 on the surface of the bearing soil layer 03. The end fixing column 133 is fixedly inserted into the inside of the fixed installation hole 04, and then the lower monitoring plate 131 is fixedly installed on the top of the bottom end fixing column 133, and then the elastic bellows 15 is installed on the top surface of the lower monitoring plate 131. The middle monitoring piece 12 is installed on the top of the elastic bellows 15 , then the second elastic bellows 15 is installed on the top surface of the middle monitoring piece 12 , and then the second middle monitoring piece is installed on the top of the second elastic bellows 15 12, then install the third elastic bellows 15 on the top surface of the second middle monitoring piece 12, then install the third middle monitoring piece 12 on the top of the third elastic bellows 15, and then install the third middle monitoring piece 12 on the top of the third elastic bellows 15. A fourth elastic bellows 15 is installed on the top surface of the middle monitoring member 12, and then a monitoring member 11 is installed on the top of the fourth elastic bellows 15, and then expansive soil is filled into the fixed borehole 02 and compacted. Until only the upper monitoring part 11 is outside the expansive soil, then dig out the cable ditch connected to the fixed borehole 02 on the ground, then put the power cable in the cable ditch, then open the monitoring box 113 and make the power cable Connect to the intelligent control processor 117, then put the monitoring box 113 back to its original position, then close the cable ditch and fill the fixed hole 02 with expansive soil. At this time, the upper monitoring element 11 is also buried in the expansive soil. The expansive soil forms the expansive soil sealing body 05 inside the fixed borehole 02, so far the installation is completed, and then the subgrade main body 01 settles under the influence of various factors, and then the subgrade main body 01 is carried by the expansive soil sealing body 05 for monitoring. After the middle monitoring member 12 and the lower monitoring member 13, between the upper and lower adjacent middle monitoring members 12, and between the middle monitoring member 12 and the upper monitoring member 11, the distance between the middle monitoring member 12 and the upper monitoring member 11 is At the same time, the elastic bellows 15 is compressed and shortened, and then the rotating horizontal bar 42 rotates under the action of the torsion of the power storage spring 43, and then the rotating horizontal bar 42 rotates with the insulating winding roller 47 through the transmission bar 48, and then the resistance wire 49 is wound into the thread groove on the outside of the insulating winding roller 47. At the same time, the insulating winding roller 47 moves to the left under the action of the thread fit between the thread groove and the male thread strip 54, which is used to assist the resistance. The wire 49 is wound to the inside of the thread groove on the insulating take-up roller 47, and then the number of resistance wires 49 wound on the outside of the insulating take-up roller 47 increases, the length increases, and then the current passing through the resistance wire 49 will decrease, and then the intelligent control processor 117 Calculate the length change of the resistance wire 49 wound outside the insulating winding roller 47 according to the current value, the length change between the lower monitoring member 13 and the first middle monitoring member 12 is A, the first middle monitoring member 12 and the second middle monitoring member The length change between the monitoring pieces 12 is B, the length change between the second middle monitoring piece 12 and the third middle monitoring piece 12 is C, and the length change between the third middle monitoring piece 12 and the upper monitoring piece 11 The quantity is D, in the When lateral displacement occurs, the settlement amount of the soil layer corresponding to the first middle monitoring element 12 is A, the settlement amount corresponding to the soil layer of the second middle monitoring element 12 is A plus B, and the third middle monitoring element 12 corresponds to the settlement of the soil layer.

Then the magnetic column 340 moves to the right end of the straight conductive sheet 344 by pulling the curved conductive sheet 349 by the determination piston 348, and then the length of the resistance sheet 345 connected to the circuit becomes shorter and the current becomes larger, and then the intelligent control processor 117 calculates according to the magnitude of the current. The distance value between the strong magnetic sphere 354 and the magnetic column 340 is calculated, and then the distance between the strong magnetic sphere 354 and the central axis of the insulating tube 341 is calculated. The force of the magnetic column 340 in the other direction is reduced, and the corresponding judgment piston 348 is in the corresponding judgment. Under the action of the elastic force of the spring 347, the corresponding curved conductive sheet 349 moves to the left, and then the length of the corresponding resistance sheet 345 connected to the circuit increases, and the current becomes smaller. The intelligent control processor 117 calculates according to the current magnitude. The distance between the central axes of the tubes 341, then the intelligent control processor 117 uses the three-point positioning principle to infer the orientation of the strong magnetic sphere 354 and its distance from the initial position, and then monitor the distance from the strong magnetic sphere 354 at the initial position. The distance from the center of the sphere 25 is fixed, and the intelligent control processor 117 can infer the angle of the corresponding component 35 and monitor the offset of the force arm 26 according to the trigonometric function. The actual settlement distance and offset distance, and then the intelligent control processor 117 obtains the specific positioning through the GPS locator 116, and then the intelligent control processor 117 wirelessly transmits the positioning information and detection information to the receiving terminal through the wireless transmitter 115.
