Description

Technical Field

[0001] This invention relates to the field of intelligent ground settlement monitoring technology, specifically to a geological disturbance road structure layer settlement monitoring sensing device. Background Technology

[0002] In areas with geological disturbance, the road structure layer is susceptible to uneven settlement, leading to road surface cracking, collapse, and other defects. The traditional monitoring method is the magnetic ring settlement meter method, which uses a flexible tape measure settlement meter in conjunction with a settlement tube and a settlement magnetic ring to monitor the amount of foundation settlement.

[0003] Settlement monitoring sensors are precision instruments used to measure the vertical settlement of the ground or buildings. They are widely used in fields such as construction engineering, rail transit, water conservancy dams, and slope monitoring, providing critical data support for engineering safety.

[0004] Magnetic settlement ring sensors are a classic contact-type geotechnical engineering monitoring tool. They work by vertically embedding a grooved PVC conduit in an underground borehole, with a magnetic ring tightly bonded to the soil layer fitted around the conduit. The core principle is that a magnetic induction probe is lowered along the conduit; when the probe approaches the moving magnetic ring, a signal is triggered. By comparing depth data measured at different times, the system accurately calculates the settlement of each soil layer. This system can achieve layered monitoring at a relatively low cost, clearly reflecting the compression of soil layers at different depths. It is a mature method for monitoring deep soil deformation in engineering projects such as roadbeds, dams, and slopes. However, the settlement ring is easily affected by the settlement conduit as it moves downwards, often getting stuck and causing inaccurate detection. Furthermore, traditional magnetic settlement ring sensors have limitations; they can only monitor vertical settlement displacement and cannot detect tilting settlement.

[0005] In order for the settlement magnetic ring to move smoothly along the settlement tube, the inner diameter of the settlement magnetic ring needs to be larger than that of the settlement tube. When the ground settlement around the settlement magnetic ring is different, the settlement magnetic ring is prone to tilting. The tilted settlement magnetic ring is prone to getting stuck outside the settlement tube and can no longer move smoothly with the ground settlement. Furthermore, the tilted settlement magnetic ring affects the accuracy of ground settlement monitoring.

[0006] Therefore, this application provides a geological disturbance road structure layer settlement monitoring sensing device to solve the problem in the prior art where the tilting of the settlement magnetic ring affects the monitoring accuracy and precision. Summary of the Invention

[0007] To address the aforementioned problems, this invention provides a sensing device for monitoring settlement of road structure layers due to geological disturbance.

[0008] The technical solution adopted by the present invention to solve its technical problem is: a geological disturbance road structure layer settlement monitoring sensing device, including a monitoring tube, a monitoring ring and an intelligent monitoring part, wherein the monitoring ring is sleeved on the outside of the monitoring tube, and an annular monitoring channel is provided inside the monitoring ring. The monitoring channel is coaxially arranged with the monitoring tube, and a positioning component is movably arranged inside the monitoring channel. The intelligent monitoring component includes a monitoring head, inside which a detection disk is rotatably mounted. The detection disk is equipped with an angle sensor, and inside which a monitoring block is rotatably mounted. The monitoring block is equipped with a monitoring magnetic block. The axis of the detection disk is horizontally positioned, and the axis of the monitoring block is perpendicular to the axis of the detection disk. The monitoring magnetic block is used to monitor the position of the positioning component. When the monitoring head approaches the positioning component, the positioning component and the monitoring magnetic block are magnetically attracted. The monitoring magnetic block drives the positioning component to move along the monitoring channel. If the detection disk does not deflect during the movement of the positioning component, it indicates that the monitoring ring has not tilted.

[0009] As an optimization, the positioning component includes two positioning seats and a positioning magnetic block, the positioning magnetic block being installed between the two positioning seats, and the positioning seats being equipped with wheels that contact the inner wall of the monitoring channel. The axis of the positioning magnetic block is arranged radially along the monitoring ring.

[0010] As an optimization, a monitoring handle is provided on the upper side of the monitoring head, and an operating rod is connected to the upper end of the monitoring handle; The monitoring block is connected to a drive motor at its axis. The output shaft of the drive motor is fixed coaxially with the monitoring block. The center of the monitoring block coincides with the axis of the detection disk. The drive motor drives the monitoring block to rotate, and the monitoring magnetic block drives the positioning component to move along the monitoring channel through magnetic attraction.

[0011] As an optimization, the center of the monitoring magnetic block coincides with the axis of the detection disk, and the magnetic attraction range between the monitoring magnetic block and the positioning component is greater than the radius of the monitoring ring. When the monitoring magnetic block approaches the monitoring ring and enters the magnetic attraction range, the detection disk deflects under the action of magnetic force.

[0012] As an optimization, a sealing layer is provided between the top of the inner ring of the monitoring ring and the monitoring tube, and between the bottom of the inner ring of the monitoring ring and the monitoring tube. The sealing layer is used to cover the soil. An annular auxiliary airbag is provided between the two sealing layers. When the auxiliary airbag is inflated, the monitoring ring and the monitoring tube are squeezed together.

[0013] As an optimization, the monitoring ring is provided with an auxiliary cavity, and a guide tube is provided inside the auxiliary cavity. A piercing needle is movably connected to the guide tube. A positioning iron block is provided at the end of the piercing needle away from the monitoring tube. An auxiliary spring is provided inside the guide tube. Under the action of the auxiliary spring, the piercing needle is completely retracted into the guide tube. When the monitoring magnetic block passes the inside of the guide tube, it magnetically attracts the positioning iron block, causing the piercing needle to move towards the monitoring tube, piercing the auxiliary airbag, and the monitoring ring and the monitoring tube are separated.

[0014] As an optimization, the outer periphery of the monitoring ring is provided with several auxiliary strips, the outer ends of which are inclined away from the monitoring tube.

[0015] As an optimization, the monitoring handle has a through mounting groove, and a guide arm is rotatably connected inside the mounting groove. The guide arm is connected to the mounting groove through a spring shaft, and guide wheels are connected to both ends of the guide arm. The inner wall of the monitoring tube is provided with a guide rail, which is used to accommodate guide wheels.

[0016] The beneficial effects of this plan are as follows: By monitoring the magnetic attraction between the magnetic block and the positioning component, combined with the angle sensor to detect the deflection of the detection disk, the drive motor drives the monitoring block to rotate, and the magnetic force pulls the positioning component to move along the monitoring channel to judge the attitude of the detection ring, determine whether the monitoring ring has settled vertically or tilted, and efficiently detect the vertical settlement data and tilt angle.

Detailed Implementation

[0031] like Figures 1-13 As shown, a geological disturbance road structure layer settlement monitoring sensing device includes a monitoring tube 1, a monitoring ring 2, and an intelligent monitoring part. The monitoring ring 2 is sleeved on the outside of the monitoring tube 1. The monitoring ring 2 has an annular monitoring channel 3 inside. The monitoring channel 3 is coaxially arranged with the monitoring tube 1. A positioning component is movably arranged inside the monitoring channel 3. The intelligent monitoring component includes a monitoring head 4, with a detection disk 5 rotatably mounted inside the monitoring head 4. The detection disk 5 is equipped with an angle sensor 6, and a monitoring block 7 is rotatably mounted inside the detection disk 5. A monitoring magnetic block 8 is mounted inside the monitoring block 7. The axis of the detection disk 5 is horizontal, and the axis of the monitoring block 7 is perpendicular to the axis of the detection disk 5. The monitoring magnetic block 8 is used to monitor the position of the positioning component. When the monitoring head 4 approaches the positioning component, the positioning component and the monitoring magnetic block 8 are magnetically attracted. The monitoring magnetic block 8 drives the positioning component to move along the monitoring channel 3. If the detection disk 5 does not deflect during the movement of the positioning component, it indicates that the monitoring ring 2 has not tilted.

[0032] The monitoring tube 1 is vertically installed in a pre-drilled hole in the foundation, with multiple monitoring rings 2 spaced apart. Backfilling is then performed to fix the position of the monitoring rings 2. When it is necessary to detect the settlement distance of the monitoring rings 2, the intelligent monitoring component is inserted into the monitoring tube 1, and the position of the monitoring rings 2 is monitored through the monitoring head 4. As the monitoring head 4 moves downwards, when it approaches the monitoring rings 2, the monitoring magnet 8 is magnetically attracted to the positioning component, and the detection disk 5 deflects from the monitoring head 4. As the monitoring head 4 moves downwards, the detection disk 5 gradually returns to its initial angle, at which point the monitoring magnet 8 is directly facing the positioning component.

[0033] like Figure 4 and Figure 5 As shown, the positioning component includes two positioning seats 9 and a positioning magnetic block 10. The positioning magnetic block 10 is installed between the two positioning seats 9. The positioning seats 9 are equipped with walking wheels 11, and the walking wheels 11 are in contact with the inner wall of the monitoring channel 3. The axis of the positioning magnetic block 10 is arranged radially along the monitoring ring 2.

[0034] The longitudinal section of the monitoring channel 3 is I-shaped, and a bearing is provided between the traveling wheel 11 and the positioning seat 9, allowing the positioning seat 9 to move smoothly along the monitoring channel 3. The traveling wheel 11 includes wheels that contact the top and sides of the monitoring channel 3, ensuring smooth movement of the positioning assembly.

[0035] like Figure 9 and Figure 10 As shown, a monitoring handle 12 is disposed on the upper side of the monitoring head 4, and an operating rod 13 is connected to the upper end of the monitoring handle 12; The monitoring block 7 is connected to a drive motor 14 at its axis. The output shaft of the drive motor 14 is fixed coaxially with the monitoring block 7. The center of the monitoring block 7 coincides with the axis of the detection disk 5. The drive motor 14 drives the monitoring block 7 to rotate. The monitoring magnetic block 8 drives the positioning component to move along the monitoring channel 3 through magnetic attraction.

[0036] The rotation direction of the drive motor 14 is perpendicular to the rotation direction of the detection disk. In the initial state, the monitoring magnetic block 8 is set horizontally and radially along the detection disk, while the monitoring block 7 is set vertically along its axis.

[0037] like Figure 11 As shown, the center of the monitoring magnetic block 8 coincides with the axis of the detection disk 5. The magnetic attraction range of the monitoring magnetic block 8 and the positioning component is greater than the radius of the monitoring ring 2. When the monitoring magnetic block approaches the monitoring ring 2 and enters the magnetic attraction range, the detection disk 5 deflects under the action of magnetic force.

[0038] As the monitoring head 4 gradually approaches the monitoring ring 2 and enters the magnetic attraction range, the detection disk deflects under the magnetic attraction, and the deflection angle is detected by the angle sensor 6. When the monitoring head 4 reaches the inner side of the positioning component, the detection disk gradually returns to its initial angle, and the deflection angle returns to zero.

[0039] like Figure 1 and Figure 4 As shown, a sealing layer 15 is provided between the top of the inner ring of the monitoring ring 2 and the monitoring tube 1, and between the bottom of the inner ring of the monitoring ring 2 and the monitoring tube 1. The sealing layer 15 is used to cover the soil. An annular auxiliary airbag 16 is provided between the two sealing layers 15. When the auxiliary airbag 16 is inflated, the monitoring ring 2 and the monitoring tube 1 are squeezed together.

[0040] The auxiliary airbag 16 is fixedly connected to the monitoring ring 2 and the monitoring tube 1, and the diameter of the auxiliary airbag 16 is not less than the distance between the monitoring tube 1 and the monitoring ring 2. The auxiliary airbag 16 can effectively prevent the monitoring ring 2 from tilting during the backfilling process.

[0041] like Figure 4 and Figure 5 As shown, the monitoring ring 2 has an auxiliary cavity inside, and a guide tube 17 is provided inside the auxiliary cavity. A piercing needle 18 is movably connected to the guide tube 17. A positioning iron block 19 is provided at the end of the piercing needle 18 away from the monitoring tube 1. An auxiliary spring is provided inside the guide tube 17. Under the action of the auxiliary spring, the piercing needle 18 is completely retracted into the guide tube 17. When the monitoring magnetic block 8 passes the inside of the guide tube 17, it magnetically attracts the positioning iron block 19, causing the piercing needle 18 to move towards the monitoring tube 1, piercing the auxiliary airbag 16, and the monitoring ring 2 and the monitoring tube 1 are separated.

[0042] A limit ring is provided in the middle of the puncture needle 18, and an auxiliary spring is located on the side of the limit ring closer to the monitoring ring 2.

[0043] like Figure 3 As shown, the outer periphery of the monitoring ring 2 is provided with a plurality of auxiliary strips 20, and the outer ends of the auxiliary strips 20 are inclined in a direction away from the monitoring tube 1.

[0044] The auxiliary strip 20 can increase the contact area between the monitoring ring and the surrounding geological layers.

[0045] like Figure 7 and Figure 11 As shown, the monitoring handle 12 has a through mounting groove 21, and a guide arm 22 is rotatably connected inside the mounting groove 21. The guide arm 22 is connected to the mounting groove 21 by a spring shaft, and guide wheels 23 are connected to both ends of the guide arm 22. The inner wall of the monitoring tube 1 is provided with a guide rail 24, which is used to accommodate the guide wheel 23.

[0046] The mounting slot 21 is equipped with two limiting rods, which are located on the upper and lower sides of the guide arm 22 respectively, so that the guide arm 22 is kept in an inclined state, and the two guide wheels 23 are set one above the other.

[0047] This solution also includes a controller for data processing and remote communication, which can be a PLC, microcontroller, or embedded system, supporting 4G / 5G / WiFi data transmission. The controller's location is set by the operator according to the actual situation during operation. The controller is used to control the electrical components used in this solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, displays, computer input devices, switches, communication devices, lights, speakers, and microphones. The controller can be an Intel processor, AMD processor, PLC controller, ARM processor, or microcontroller. It is also used in conjunction with a motherboard, memory modules, storage media, and power supply, which can be AC ​​power or a lithium battery. When a display screen is included, a graphics card is also included.

[0048] How to use: First, pre-drill holes at the locations to be monitored; According to the monitoring depth, fix several monitoring rings 2 on the monitoring pipe 1, and then lower the monitoring pipe 1 with the monitoring rings 2 arranged into the pre-drilled hole; Backfilling is completed. After backfilling, the intelligent monitoring part is extended downward by operating rod 13. When the monitoring head 4 passes through the monitoring ring 2, the positioning iron block 19 is magnetically attracted by the monitoring magnetic block 8, so that the positioning iron block 19 pushes the piercing needle 18 to move towards the auxiliary airbag 16, piercing the auxiliary airbag 16. The monitoring ring 2 and the monitoring tube 1 are unlocked, and the monitoring ring 2 monitors the settlement of the surrounding geological layer. When it is necessary to monitor the settlement of the geological layer, the monitoring head 4 is inserted into the monitoring tube 1 by operating lever 13, and the monitoring head 4 is pushed downward. When the monitoring head 4 moves to the upper side of the monitoring ring 2 and enters the magnetic attraction range of the monitoring magnetic block 8 and the positioning magnetic block 10, the monitoring magnetic block 8 causes the detection disk 5 to deflect under the magnetic attraction. The angle sensor 6 detects the change in tilt angle and transmits a signal to the controller. As the monitoring head 4 continues to move downward, it enters the inner side of the monitoring ring 2, and the monitoring magnetic block 8 and the positioning magnetic block 10 are positioned opposite each other, achieving the desired effect. Figure 11 The first state is shown, in which the detection disk 5 deflects in the opposite direction until it returns to the initial state; The monitoring block 7 is rotated by the drive motor 14, and the positioning component moves along the monitoring channel 3 under the magnetic attraction. If the detection disk 5 does not deflect during the rotation of the monitoring block 7, it indicates that the monitoring ring 2 has not tilted, and the depth of the monitoring head 4 at this time is the depth of the monitoring ring 2. During the rotation of monitoring block 7, if the tilt sensor detects the deflection of detection disk 5, it indicates that monitoring channel 3 has tilted, meaning that monitoring ring 2 has tilted and settled. Figure 12 The second detection state is shown; As the monitoring head 4 continues to move downwards, the angle between the monitoring magnetic block 8 and the positioning magnetic block 10 decreases, and the deflection angle of the detection disk 5 decreases. The driving motor 14 continues to rotate the monitoring block 7. During the rotation of the monitoring block 7, the deflection angle of the detection disk 5 remains unchanged, indicating that this position is the center point of the monitoring ring 2. Figure 13 The third detection state is shown. At this time, the monitoring magnetic block 8 is located on the center line of the monitoring channel 3, the depth of the monitoring head 4 is the depth of the monitoring ring 2, and the deflection angle of the detection disk 5 is the deflection angle of the monitoring ring 2.
