Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of soil stratified settlement monitoring technology, and specifically relates to a stratified settlement monitoring device. Background Technology
[0002] When constructing highways, industrial buildings, and civil structures in soft soil, mountainous, and hilly areas, foundation treatment or backfilling is often necessary to improve the bearing capacity, surface elevation, or smoothness of the foundation. Layered soil settlement monitoring uses equipment embedded in the soil layers to monitor the vertical displacement changes at different depths, assessing foundation stability, predicting settlement trends, and guiding construction safety. Traditional monitoring methods typically employ magnetic ring settlement meters. Measurement tubes are embedded at monitoring points, and magnetic rings are placed on the tubes at regular intervals. After installation, a probe detects changes in the position of the magnetic rings through magnetic induction, and then the settlement of each soil layer is calculated. This method suffers from low monitoring accuracy and efficiency, and is susceptible to magnetic field interference. Therefore, designing a more accurate and efficient layered soil settlement monitoring device is essential. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a stratified settlement monitoring device that can overcome the problem of the existing technology being susceptible to magnetic field interference, and has the advantages of improving the accuracy and efficiency of settlement monitoring.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A stratified settlement monitoring device, comprising:
[0006] A measuring tube, wherein a magnetic ring is fitted on the outer circumferential surface of the measuring tube, and the magnetic ring slides along the length of the measuring tube;
[0007] A transparent graduated groove is provided on the inner wall of the measuring tube and extends along the length of the measuring tube. The opening of the transparent graduated groove faces the inner wall of the measuring tube. A magnetic bead is provided in the opening of the transparent graduated groove, and the magnetic bead and the magnetic ring are magnetically attracted to each other.
[0008] The processor is electrically connected to a traction wire, and the end of the traction wire is electrically connected to a camera. The camera is placed inside the measuring tube via the traction wire, and the camera's image-facing end faces the magnetic bead.
[0009] Furthermore, there are multiple measuring tubes, and the ends of adjacent measuring tubes are detachably connected by connectors.
[0010] Furthermore, the connector is a connecting clamp, a threaded sleeve, or a rubber sleeve.
[0011] Furthermore, a bottom cover is detachably connected to the bottom end of several of the measuring tubes.
[0012] Furthermore, the bottom cover is inserted into the measuring tube.
[0013] Furthermore, the bottom cover is conical.
[0014] Furthermore, the transparent graduated grooves of adjacent measuring tubes are arranged opposite to each other and are interconnected.
[0015] Furthermore, the inner wall of the measuring tube is provided with a plurality of positioning slots, which are spaced apart along the length of the measuring tube. The transparent scale groove engages with the plurality of positioning slots, and the opening of the transparent scale groove abuts against the inner wall of the measuring tube.
[0016] This utility model has the following beneficial effects:
[0017] This invention places both the measuring tube and the magnetic ring underground. A camera is lowered into the measuring tube via a traction wire, and the processor remains relatively fixed to keep the camera relatively stationary. Therefore, during the settling process of the measuring tube, the camera can capture real-time images of the relative changes between the magnetic bead and the scale on the transparent groove. The camera then transmits the captured images to the processor (image processor) for comparison, thereby obtaining the settlement status of the measuring tube. Compared to existing technologies that use a probe to sense changes in the magnetic ring's position through magnetic induction to calculate the settlement of each soil layer, this invention effectively overcomes the problems of low monitoring accuracy and efficiency caused by magnetic field interference, and offers the advantages of high monitoring accuracy and high processing efficiency.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Terms such as “upper,” “inner,” “middle,” “left,” “right,” and “one” used in this specification are merely for clarity of description and are not intended to limit the scope of the present invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the present invention.
[0024] This invention addresses the shortcomings of existing technologies that use probes to sense changes in the position of a magnetic ring 4 via magnetic induction to calculate the settlement of soil layers. These technologies are susceptible to magnetic field interference, leading to low monitoring accuracy and efficiency. Therefore, this invention designs an image recognition-based layered settlement monitoring device to overcome these problems. The structure of this layered settlement monitoring device is described in detail below:
[0025] A stratified settlement monitoring device, such as Figures 1 to 4 As shown, the device includes a measuring tube 1, a transparent scale groove 3, and a processor 8. A magnetic ring 4 is fitted on the outer circumference of the measuring tube 1, and the magnetic ring 4 can slide along the length of the measuring tube 1. The transparent scale groove 3 is detachably set on the inner wall of the measuring tube 1, and the transparent scale groove 3 extends along the length of the measuring tube 1. The two ends of the transparent scale groove 3 are aligned with the two ends of the measuring tube 1, and the opening of the transparent scale groove 3 faces the inner wall of the measuring tube 1. A magnetic bead 5 is set in the opening of the transparent scale groove, and the magnetic bead 5 can roll in the transparent scale groove 3. The magnetic bead 5 and the magnetic ring 4 are magnetically attracted to each other. The processor 8 is an image processor 8 (such as a computer). The processor 8 is electrically connected to a traction wire 10. The traction wire 10 is a high-strength cable with a protective layer and an insulating layer on its surface. The end of the traction wire 10 is electrically connected to a camera 9. The camera 9 is placed in the measuring tube 1 through the traction wire 10 and the existing fixed pulley bracket, and the camera end of the camera 9 is kept facing the magnetic bead 5.
[0026] Therefore, when both the measuring tube 1 and the magnetic ring 4 are installed underground, the camera 9 is lowered into the measuring tube 1 via the traction wire 10, and the processor 8 is kept relatively fixed to keep the camera 9 relatively fixed. Thus, during the settlement of the measuring tube 1, the camera 9 can be used to capture the relative change between the magnetic bead 5 and the scale on the transparent scale groove 3 in real time. At this time, the camera 9 will transmit the captured image to the processor 8 (image processor 8) so that the processor 8 can compare the images before and after to obtain the settlement of the measuring tube 1. Compared with the existing technology that uses the probe to sense the position change of the magnetic ring 4 through the magnetic effect to calculate the settlement of each soil layer, the technology of this utility model can effectively overcome the problem of low monitoring accuracy and low monitoring efficiency caused by the easy influence of magnetic field interference on the results, and has the advantages of high monitoring accuracy and high processing efficiency.
[0027] In this embodiment, to increase the depth of settlement monitoring, multiple measuring tubes 1 are used. A connector 2 is detachably connected between the ends of adjacent measuring tubes 1 to connect two measuring tubes 1. The connector 2 can be a clamp, threaded sleeve, or rubber sleeve joint to make the connection between adjacent measuring tubes 1 efficient and convenient. Meanwhile, the transparent scale grooves 3 of adjacent measuring tubes 1 are opposite and interconnected. Therefore, when using the camera 9 to monitor the magnetic beads 5 of other measuring tubes 1, only the height of the camera 9 needs to be raised or lowered, without adjusting the camera 9's rotation, thus simplifying operation.
[0028] In this embodiment, a bottom cover 7 is detachably connected to the bottom end of a plurality of measuring tubes 1. The bottom cover 7 is inserted into the end of the measuring tube 1. The inner wall of the bottom cover 7 is provided with anti-slip rubber, which can improve the stability of the bottom cover 7 installation. The bottom cover 7 is conical in shape. Therefore, when multiple measuring tubes 1 are installed underground as a whole, the resistance between the measuring tube 1 and the soil can be reduced when settlement occurs, so that the settlement effect is more significant and helps to improve the monitoring effect.
[0029] In this embodiment, a plurality of positioning slots 6 are fixedly provided on the inner wall of the measuring tube 1. The plurality of positioning slots 6 are distributed at intervals along the length of the measuring tube 1. The transparent scale groove 3 is engaged with the plurality of positioning slots 6 to realize the function of detachable engagement between the transparent scale groove 3 and the measuring tube 1. The opening of the transparent scale groove 3 abuts against the inner wall of the measuring tube 1, providing space for the magnetic bead 5 to slide in the transparent scale groove 3.
[0030] Based on the above introduction to the structure of the stratified settlement monitoring device, the following provides a detailed introduction to its usage:
[0031] Step 1: Before conducting stratified settlement monitoring of soil at the monitoring point, drill hole 12 at the monitoring point location using a drilling rig. When drilling hole 12, pay attention to the wall and verticality of hole 12. The depth of hole 12 should be slightly greater than the monitoring depth, and the diameter of hole 12 should be slightly greater than the diameter of measuring tube 1.
[0032] Step 2: Set the transparent scale groove 3 on the multiple positioning slots 6 of the measuring tube 1, and place the magnetic bead 5 in the transparent scale groove 3.
[0033] Step 3: Connect the test tubes 1 one by one through the connector 2, and seal the bottom of the test tubes 1 with the bottom cover 7 of the test tubes 1.
[0034] Step 4: Install the magnetic ring 4 onto the settling pipe according to the monitoring distance specified in the monitoring plan. During installation, the magnetic ring 4 should move upwards along with the measuring tube 1 in this section so that the magnetic bead 5 can be attracted to the corresponding position of the magnetic ring 4. Afterwards, the existing positioning ring can be used to effectively isolate the magnetic ring 4.
[0035] Step 5: Insert the probe 1 with the magnetic ring 4 into the borehole 12, ensuring that the magnetic ring 4 is delivered to the predetermined depth along with the probe 1. Next, lift the probe 1 upwards by about 1 meter to ensure that the magnetic ring 4 is not obstructed when moving within a range of about 1 meter up and down. Afterwards, fill the space between the probe 1 and the borehole wall of the borehole 12 with fine soil.
[0036] Step Six: Connect one end of the traction wire 10 to the camera 9 and the other end to the image processor 8. Insert the camera module into the upper opening of the measuring tube 1, ensuring that the camera module can capture the specific position of each magnetic bead 5 in each section of the measuring tube 1. Subsequently, the image processor 8 converts these position images into corresponding numerical data and records the initial measurement values.
[0037] Step 7: Repeat step 6 at regular monitoring intervals, and further analyze the settlement values of the soil 11 at the corresponding elevation by calculating the positional changes of the magnetic bead 5.
[0038] The embodiments of this utility model are not limited thereto. Based on the above content of this utility model, using ordinary technical knowledge and conventional means in the field, without departing from the basic technical idea of this utility model, this utility model can also be modified, replaced or combined in various other forms, all of which fall within the scope of protection of this utility model.
