[0044] Figure 1 It is a schematic diagram of an intelligent monitoring device for differential settlement of the entire cross section of a roadbed according to an illustrative embodiment of the present utility model.

[0045] According to the utility model, a roadbed full-section differential settlement intelligent monitoring device is provided. Figure 1 As shown, it includes a settlement tube 1, a monitoring component 2 and a signal collector 3. The settlement tube 1 is horizontally installed in the roadbed and is configured to extend in a first direction; the monitoring component 2 is movably installed in the settlement tube 1 and includes a housing 21, a displacement sensor and a gravity sensor. The displacement sensor is installed in the housing 21 and is suitable for obtaining the horizontal movement distance of the monitoring component 2 in the settlement tube 1. The gravity sensor is installed in the housing 21 and is suitable for obtaining the deflection angle of the monitoring component 2 relative to the horizontal plane; the signal collector 3 is installed outside the settlement tube 1, communicates with the displacement sensor and the gravity sensor, and is suitable for obtaining the first settlement data of any position of the settlement tube 1 based on the horizontal movement distance and the deflection angle.

[0046] According to the above-mentioned arrangement, the settlement tube 1 is horizontally installed in the roadbed, and the movable monitoring component 2 in the settlement tube 1 is equipped with a displacement sensor and a gravity sensor, as well as an external signal acquisition device, thereby achieving comprehensive monitoring of the roadbed settlement. Specifically, the settlement tube is pre-installed horizontally in the roadbed. When the roadbed settles, the settlement tube 1 will also bend with the roadbed settlement. At this time, the displacement sensor and gravity sensor installed in the movable monitoring component 2 in the settlement tube 1 can be used to obtain the movement distance of the monitoring component 2 in the settlement tube 1 and the deflection angle relative to the horizontal plane. Furthermore, the external signal acquisition device 3 can calculate the first settlement data of any position in the settlement tube 1 based on the movement distance and deflection angle.

[0047] In detail, the first settlement data is the settlement distance of any position in the settlement tube 1 relative to the end leveling point 7 at the end of the settlement tube 1.

[0048] In an illustrative embodiment, Figure 1 As shown, the extension direction of the sedimentation tube 1, ie, the first direction, is configured to be parallel to the width direction of the roadbed.

[0049] In an illustrative embodiment, the material of the settling pipe 1 includes high-strength PVC flexible plastic, which has good ductility and is not easy to wear when subjected to pressure in an underground environment.

[0050] Figure 2 It is a three-dimensional schematic diagram of an intelligent monitoring device for differential settlement of the entire cross-section of a roadbed according to an illustrative embodiment of the present utility model.

[0051] In an illustrative embodiment, Figure 2 As shown, the intelligent monitoring device for differential settlement of the full cross-section of the roadbed further includes a guide mechanism, which is suitable for guiding the monitoring component 2 to move along the axial extension direction of the settlement tube 1.

[0052] According to the above-mentioned setting method, the guide mechanism is used to ensure that the monitoring component 2 can move smoothly along the axial direction of the sedimentation tube 1, which helps to prevent the monitoring component 2 from deviating or getting stuck in the sedimentation tube 1, thereby improving the stability of the entire monitoring device.

[0053] In an illustrative embodiment, Figure 2 As shown, the guide mechanism includes two chutes 11 and a plurality of guide units. The two chutes 11 are symmetrically arranged in the vertical direction on the inner wall of the settling tube 1 and are configured to extend in a first direction. The plurality of guide units are symmetrically arranged in the vertical direction and installed at intervals in the first direction on the upper and lower sides of the housing 21. They are adapted to cooperate with the chutes 11 to move the monitoring assembly 2 along the axis of the settling tube 1.

[0054] According to the above-described configuration, the guide mechanism consists of two chutes 11 and multiple guide units. The two chutes 11 are symmetrically arranged on the inner wall of the settlement tube 1 and extend in a first direction, providing a fixed movement path for the monitoring assembly 2. Multiple guide units are symmetrically and spaced apart on the upper and lower sides of the housing 21 of the monitoring assembly 2. These guide units cooperate with the chutes 11 to ensure that the monitoring assembly 2 can move smoothly and precisely along the axis of the settlement tube 1. This improves the linearity and stability of the movement of the monitoring assembly 2 and reduces measurement errors caused by axial and circumferential deviations of the monitoring assembly 2, resulting in more accurate monitoring of roadbed settlement.

[0055] In an illustrative embodiment, Figure 2 As shown, four chutes 11 are provided, which are symmetrically arranged in pairs on the inner wall of the settling tube 1 in the vertical direction and the horizontal direction.

[0056] In detail, the two chutes 11 in the horizontal direction are also applicable to other measurement scenarios besides roadbed settlement monitoring.

[0057] Figure 3It is a three-dimensional schematic diagram of a monitoring component according to an illustrative embodiment of the present utility model.

[0058] In an illustrative embodiment, Figure 2 、 Figure 3 As shown, each guide unit includes a guide arm 23 and an elastic member 24. One end of the guide arm 23 is rotatably mounted on the housing 21 within the vertical cross-section of the housing 21, and the elastic member 24 is installed between the housing 21 and the guide arm 23. In response to the tension of the elastic member 24, the guide arm 23 is kept in the chute 11 at the end away from the housing 21, and the housing 21 is positioned at the axis of the settling tube 1.

[0059] In an illustrative embodiment, Figure 3 As shown, the elastic member 24 includes a spring, and both ends of the spring are fixedly mounted on the guide arm 23 and the housing 21 respectively.

[0060] According to the above-mentioned setting method, the elastic member 24 includes a spring. Through the elastic force of the elastic member 24, the guide arm 23 is always in the slide groove 11 and maintains a certain pressure on the slide groove 11, ensuring that the monitoring component 2 will not deviate from the axis of the sedimentation tube 1 during the movement. Even if the roadbed undergoes slight deformation or vibration, the stability and measurement accuracy of the monitoring component 2 can be maintained.

[0061] In an exemplary embodiment, the elastic member 24 includes a torsion spring installed on the rotating shaft between the guide arm 23 and the housing 21 , and is adapted to provide a driving force to move one end of the guide arm 23 away from the housing 21 .

[0062] In an illustrative embodiment, Figure 3 As shown, the guide unit further includes a pulley 22 rotatably mounted on an end of the guide arm 23 away from the housing 21 and configured to roll in the slide groove 11 .

[0063] According to the above arrangement, the pulley 22 enables the monitoring assembly 2 to roll smoothly in the chute 11 in the settling tube 1, thereby reducing friction, improving movement accuracy and reducing wear and tear of the guide unit.

[0064] In an illustrative embodiment, Figure 3 As shown, four guide units are provided, and two guide units are installed at intervals on the upper side and the lower side of the housing 21 .

[0065] In an illustrative embodiment, Figure 2 、 Figure 3As shown, the intelligent monitoring device for differential settlement of the full section of the roadbed also includes two measuring ropes 4, which are respectively installed at the two opposite ends of the shell in the first direction and extend to the two ends of the settlement tube 1 respectively. Each measuring rope 4 is suitable for pulling the monitoring component 2 to slide in the settlement tube 1.

[0066] According to the above arrangement, a measuring rope 4 is further installed at two opposite ends of the housing 21 in the first direction, and extends to both ends of the settlement tube 1. Each measuring rope 4 is used to pull the monitoring assembly 2 to slide within the settlement tube 1, thereby achieving precise control and movement of the monitoring assembly 2, ensuring accurate collection of settlement data and efficient monitoring.

[0067] In an exemplary embodiment, the measuring rope 4 is made of stainless steel, nylon, polyester, or other flexible materials with high tensile strength and corrosion resistance.

[0068] In an illustrative embodiment, Figure 2 、 Figure 3 As shown, the gravity sensor includes a gravity displacement probe 25 , which is suspended in the housing 21 through a measuring line 26 .

[0069] According to the above-described arrangement, the gravity sensor employs a gravity displacement probe 25, which is suspended within the housing 21 via a measuring line 26. The gravity displacement probe 25 senses the inclination angle of the monitoring assembly 2 relative to the horizontal plane within the settlement tube 1. The suspension of the measuring line 26 ensures that the gravity displacement probe 25 can swing freely in three-dimensional space, thereby improving the accuracy of the measurement data and helping the probe 25 respond more sensitively to changes in gravity, thereby accurately monitoring the settlement of the roadbed.

[0070] In an exemplary embodiment, the measuring line 26 is a nylon rope having good tensile strength.

[0071] Figure 4 is a cross-sectional view of a monitoring assembly according to an exemplary embodiment of the present invention.

[0072] In an illustrative embodiment, Figure 4 As shown, the gravity displacement probe 25 can reflect the inclination angle with the horizontal direction in real time. When the gravity displacement probe 25 is deflected relative to the horizontal direction in the vertical section of the shell 21, it means that the monitoring component 2 has deflected vertically during the movement, and vertical settlement has occurred inside the roadbed. The deflection angle at this time is recorded. When the gravity displacement probe 25 is deflected relative to the horizontal direction in the transverse section of the shell 21, it means that the settlement tube 1 of the monitoring component 2 has deflected circumferentially during the movement. The deflection angle at this time is recorded, and the measured data is further corrected based on the recorded deflection angles of each position to ensure the accuracy of the results.

[0073] In detail, the gravity displacement probe 25 can record the internal inclination angle of the roadbed in real time, and convert the detected data at the signal acquisition instrument 3 to obtain the real-time maximum vertical settlement and the first settlement data at any position in the settlement tube 1.

[0074] In an illustrative embodiment, Figure 1 As shown, the end of the settlement pipe 1 extends to the outside of the side slope of the roadbed.

[0075] According to the above arrangement, the end of the settlement tube 1 extends outside the slope of the roadbed, which facilitates the installation and maintenance of monitoring equipment, reduces the direct impact of the internal environment on the monitoring equipment, and improves the efficiency and safety of data collection.

[0076] In an exemplary embodiment, the opening at the end of the sedimentation tube 1 is exposed 20 mm to 50 mm from the roadbed slope.

[0077] In an illustrative embodiment, Figure 1 As shown, the intelligent monitoring device for differential settlement of the entire cross-section of the roadbed also includes a total station 5, which is installed outside the settlement tube 1 and is suitable for obtaining second settlement data of the end of the settlement tube 1 based on the fixed leveling point 6 and the end leveling point 7 at the end of the settlement tube 1; wherein, the signal acquisition instrument 3 is also suitable for obtaining total settlement data at any position of the settlement tube 1 based on the first settlement data and the second settlement data.

[0078] In detail, the fixed leveling point 6 is a known absolute elevation leveling point close to the roadbed, and the position where one end of the settlement pipe 1 is exposed is used as the end leveling point 7.

[0079] According to the above-mentioned configuration, the intelligent monitoring device for full-section differential settlement of the roadbed is equipped with a total station 5, which is installed on the exterior of the settlement tube 1. The total station 5 can accurately obtain secondary settlement data at the end of the settlement tube 1 based on a preset fixed leveling point 6 and an end leveling point 7 at the end of the settlement tube 1. The secondary settlement data is the settlement distance of the end leveling point 7 relative to the fixed leveling point 6. Furthermore, the signal acquisition device 3 can calculate the total settlement data at any location in the settlement tube 1 based not only on the primary settlement data collected by the displacement sensor and gravity sensor, but also on the secondary settlement data provided by the total station 5.

[0080] Specifically, a total station 5 is aligned with a fixed leveling point 6 and an end leveling point 7 to obtain second settlement data at the end of the settlement tube. The signal acquisition device 3 records the first settlement data of the monitoring component 2 relative to the end leveling point 7 of the settlement tube 1. The two data are superimposed to obtain total settlement data at any position on the settlement tube 1. This combined use of the total station 5 and the signal acquisition device 3 improves the accuracy of the monitoring data and enhances the functionality and practicality of the monitoring device, providing reliable data support for comprehensive analysis and assessment of roadbed settlement.

[0081] In an illustrative embodiment, the total station 5 includes a Topcon GPT-4000LN total station.

[0082] Figure 5 It is a principle diagram of an intelligent monitoring device for differential settlement of the entire cross section of a roadbed according to an illustrative embodiment of the present utility model.

[0083] In an illustrative embodiment, Figure 5 As shown, when the roadbed undergoes slight vertical settlement, the settlement tube 1 also settles and bends with the roadbed, making the movement of the monitoring component 2 in the settlement tube 1 a portion of any smooth arc. Point O is the center of the arc, and point C is the end leveling point 7. When the monitoring component 2 is located at the end leveling point C of the settlement tube 1, the initial angle θ1 between the gravity displacement probe 25 and the horizontal direction can be obtained. When the monitoring component 2 is located at point B of the settlement tube 1, the angle between the gravity displacement probe 25 and the horizontal direction is 0, indicating that the maximum vertical settlement has been reached. According to the measurement, the surface length of the roadbed is 2L. Then the relative horizontal distance AC from point B to point C is L. Further, the settlement displacement radius OC can be obtained as L / sinθ1. At this time, the maximum settlement distance AB of the roadbed is calculated to be L / sinθ1-Ltanθ1.

[0084] Figure 6 It is an intelligent monitoring device for differential settlement of the entire cross section of a roadbed according to another exemplary embodiment of the present utility model.

[0085] In an illustrative embodiment, Figure 6 As shown, when the monitoring component 2 is located at any point of the sedimentation pipe 1, as shown in Figure 5 At point E, the initial angle θ2 between the gravity displacement probe 25 and the horizontal direction can be obtained. By calculating the relative vertical distance OD of point E relative to point O as Lcosθ2 / sinθ1, the first settlement data AD of point E is the difference between the relative vertical distance from point E to point O and the relative distance from point O to the end leveling point C: Lcosθ2 / sinθ1-Ltanθ1.

[0086] It should be noted that the above-mentioned arc is only an auxiliary calculation method for calculating the settlement difference between two points. The final cross-section settlement of the roadbed is composed of a number of measuring points connected together and can be in any form.

[0087] In an illustrative embodiment, the intelligent monitoring device for differential settlement of the entire cross-section of the roadbed further includes an alarm component, which is communicatively connected to the signal acquisition device 3 and is adapted to issue a warning when the total settlement data is greater than a preset value.

[0088] Based on the above configuration, the intelligent monitoring device for full-section differential settlement of the roadbed is equipped with an alarm component. When the total settlement data exceeds a preset threshold, the alarm component triggers a warning signal, notifying relevant personnel to take timely measures. This effectively improves the ability to quickly respond to roadbed settlement conditions and ensures safe operation and maintenance of the highway.

[0089] In an exemplary embodiment, the alarm component includes a buzzer alarm.

Although each embodiment has been described separately above, this does not mean that the measures in each embodiment cannot be used in combination to advantage.
