Description

Technical Field

[0001] This invention relates to the field of pile foundation settlement detection technology, specifically to a pile foundation settlement detection device and detection method for engineering testing. Background Technology

[0002] The pile foundation settlement testing equipment and method for engineering testing is a specialized technical solution that relies on mechanical structures to achieve settlement measurement. The equipment includes a support frame, displacement transmission rod, mechanical scale, and positioning components, which directly captures the vertical displacement of the pile foundation through mechanical transmission. The testing method is based on mechanical positioning, step-by-step measurement, and difference calculation, without relying on electronic sensors, and accurately obtains pile foundation settlement data, providing reliable mechanical measurement support for the stability assessment of engineering pile foundations.

[0003] In practical use, traditional settlement detection equipment is easily affected by external environmental vibrations when construction machinery is running, vehicles are passing, or other vibration sources generate impacts. The equipment often has difficulty effectively distinguishing between actual pile foundation settlement and transient vibration displacement, resulting in jumps and distortions in monitoring data. In severe cases, it may even trigger false alarms. This not only affects the continuity of data and the accuracy of measurement, but also brings significant trouble to engineering safety assessment and judgment, ultimately reducing the effectiveness of settlement detection equipment in practical applications.

[0014] A method for detecting pile foundation settlement using engineering testing equipment, the method comprising: S01: Securely install the testing equipment body in a location near the pile foundation that is not easily disturbed by direct disturbance, and level the base surface; ensure that the measuring end of the measuring rod is in close and perpendicular contact with the measuring point of the pile foundation and fix it; check and confirm that the mechanical counter and each transmission component are in the initial working state; S02: When actual settlement occurs in the pile foundation, the measuring rod moves vertically, driving the transmission gear to rotate through the lever and rack; the transmission gear drives the ratchet to rotate in one direction through the overpressure clutch, and drives the mechanical counter to accumulate and record the settlement through the transmission rod; S03: When the transmission gear rotates, it drives the rotating ring and the extrusion block to rotate, forcing the fluid into the display column; the fluid pushes the moving ring and the scale plate to move up, visually displaying the amplitude of the transmission action. This indicated value can be compared with the data recorded by the mechanical counter to determine whether any system has a fault or abnormal deviation. S04: When external vibration is transmitted to the equipment, the pendulum swings and drives the vibration pawl to move laterally; the vibration pawl engages with the ratchet tooth groove, forming a two-way lock with the settling pawl, preventing the ratchet from rotating and avoiding misrecording of vibration displacement; S05: When the pendulum swings to the threshold, it touches and pushes the touch block; the touch block moves the display block through the moving rod, and its position reflects the vibration intensity. If the vibration intensity is too high, when the moving block touches the trigger switch, the alarm will sound immediately and remotely remind the user; the vibration counter records one threshold vibration simultaneously. S06: When the touch block moves, it drives the magnetic isolation mechanism to adjust the magnetic force and accelerate the pendulum ball to stop; then the mechanism is linked to release the limit block from the touch block, and the touch block returns to the initial position under the action of the movable spring. S07: When the transmission amplitude reaches the threshold or is abnormal, the moving ring moves to the top and triggers the micro switch. The electromagnetic block is energized to attract and squeeze the ring to reset, causing the fluid in the indicating system to flow back. At the same time, the alarm is activated, issuing an abnormal alarm and remotely reminding the user. S08: During regular inspections, push the card block to slide the cleaning plate along the scale plate surface to remove accumulated dust; read the cumulative settlement value of the mechanical counter on site, obtain the historical maximum vibration intensity through the display block position, and combine the count value of the vibration counter to comprehensively assess the pile foundation settlement stability and the impact of external vibration environment.

[0015] Beneficial effects The technical solution provided by this invention has the following advantages compared with the known prior art: I. This invention, by setting up a transmission locking mechanism and other components, and through the engagement of a settlement pawl and a vibration pawl with a ratchet and an elastic connection between them and the detection device body via a spring, allows the settlement pawl to allow the ratchet to rotate unidirectionally and drive a mechanical counter to record the displacement when actual settlement occurs in the pile foundation. However, when subjected to external vibration interference, the pendulum causes the vibration pawl to engage with the ratchet, preventing its rotation. This achieves automatic differentiation and locking of actual settlement and vibration displacement, effectively avoiding monitoring data jumps and false alarms caused by vibration, and significantly improving the accuracy and reliability of settlement detection.

[0016] Second, by setting up a vibration display component and an action indicator component, and through the synergistic effect of components such as a touch block, display block, alarm, conveyor ring, display column, and scale plate, the present invention enables the equipment to not only intuitively reflect the vibration intensity and frequency through the displacement of the display block, but also clearly indicate the action status of the transmission gear through the movement of the scale plate. This provides workers with real-time and visual feedback on the vibration impact and equipment operation, facilitating timely identification of anomalies and the implementation of countermeasures, and further enhancing the monitoring controllability and data reliability of the equipment in complex construction environments.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] The present invention will be further described below with reference to embodiments.

[0022] See attached document Figure 1-13A pile foundation settlement testing device for engineering testing includes: a testing device body 1, a mechanical counter 2 detachably connected to one side of the testing device body 1, and a transmission locking mechanism 3 for locking during vibration. The transmission locking mechanism 3 includes a measuring rod 301, with one measuring end of the measuring rod 301 contacting a pile foundation measuring point. The other end of the measuring rod 301 is hinged to a lever 302, which is hinged to the testing device body 1. One end of the lever 302 is hinged to a rack 303, and one side of the rack 303 engages with a transmission mechanism. Gear 304 is rotatably connected to the detection equipment body 1. A ratchet 305 is fixedly connected to one side of the transmission gear 304 via an overpressure clutch, and the ratchet 305 is rotatably connected to the interior of the detection equipment body 1. A sinking pawl 306 engages on one side of the ratchet 305, and the sinking pawl 306 is rotatably connected to the detection equipment body 1. The sinking pawl 306 is elastically connected to the detection equipment body 1 via a sinking pawl spring. A vibrating pawl 307 engages on one side of the ratchet 305, and the vibrating pawl 307 is rotatably connected to the detection equipment body 1. The device is dynamically connected, and the vibrating pawl 307 is elastically connected to the detection device body 1 via a pull spring. A pendulum ball 308 is hinged to one side of the vibrating pawl 307 via a swing arm. A transmission rod 309 is fixedly connected to one side of the ratchet 305, and the transmission rod 309 is fixedly connected to the drive end of the mechanical counter 2. A vibration display component 310 is provided on one side of the pendulum ball 308, and an action indication component 311 is provided on one side of the transmission gear 304. The measuring rod 301 can be reliably fixed to the pile foundation to be tested using bolts or other commonly used connectors in the prior art. It can be flexibly replaced or adjusted in position according to actual testing needs. It is worth noting that in this technical solution, all hinged and rotating connections of the measuring rod 301, lever 302, rack 303, and transmission gear 304 that constitute the transmission chain are equipped with clamping springs or other elastic elements. These elastic elements are used to continuously provide preload, eliminate gaps between transmission pairs, and ensure the continuity and accuracy of displacement transmission during pile settlement. This effectively avoids data errors caused by loose connections or poor meshing, and ensures the reliability of long-term monitoring. The measuring rod 301 has its measuring end closely attached to the pile foundation measuring point to accurately capture settlement displacement. Its other end, hinged lever 302, rotates synchronously with the settlement, thereby driving the rack 303 to move smoothly. The rack 303 meshes with the transmission gear 304, driving its rotation. The transmission gear 304 synchronously drives the ratchet 305 to rotate. The settlement pawl 306 is elastically connected to the detection device body 1 via a pawl spring and meshes with the ratchet 305, achieving unidirectional transmission during actual pile foundation settlement to ensure settlement displacement. The vibration pawl 307 on the other side is also elastically connected to the detection equipment body 1 via a pull spring. Its pendulum ball 308, fixedly connected via a swing arm, swings when subjected to vibrations from external sources such as construction machinery or passing vehicles, causing the vibration pawl 307 to move. Under the force of the pendulum ball 308, the vibration pawl 307 shifts laterally and engages with the ratchet 305. At this point, the settling pawl 306 and the vibration pawl 307 are locked together, preventing the ratchet 305 from rotating further. This enables precise differentiation between actual pile foundation settlement and transient vibration displacement. When the ratchet 305 rotates, it drives the mechanical counter 2 through the transmission rod 309 to perform precise counting. The vibration display component 310 can provide real-time feedback on the intensity and frequency of vibration, while the action indicator component 311 clearly displays the action state of the transmission gear 304. The displacement fluctuation data that may occur under vibration collected by both can be compared and analyzed with the settlement data recorded by the mechanical counter 2 to further verify the reliability of the monitoring results. This effectively solves the problem of frequent false alarms caused by the inability of traditional settlement detection equipment to distinguish between vibration and settlement, resulting in distorted monitoring data. It significantly improves the continuity and measurement accuracy of monitoring data, providing solid and reliable support for the stability assessment of engineering pile foundations. At the same time, it enhances the anti-interference ability of the equipment in complex construction environments, reduces engineering safety hazards caused by data errors, extends the service life of the core components of the equipment, reduces later maintenance costs, and makes engineering safety judgments more scientific and rigorous. See attached document Figure 1-8The vibration display component 310 is used to sense the swing amplitude of the pendulum ball 308 and visually display the intensity and frequency of the vibration. It triggers an alarm when the vibration exceeds the limit. The component includes a touch block 3101, which is located on one side of the pendulum ball 308. The touch block 3101 is elastically connected to the detection device body 1 via a movable spring (not shown in the figure). A limit groove is formed on the top of the touch block 3101, and a limit block 3102 is provided at the top of the limit groove. The bottom of the limit block 3102 is inserted into the limit groove, and the limit block 3102 is elastically connected to the detection device body 1 via a support spring. The detection device body 1 has an internal cavity (not shown in the figure). The touch block 3101... A movable rod 3103 is provided on one side of the device, and the movable rod 3103 is hinged to the inside of the cavity. A display block 3104 is provided at the other end of the movable rod 3103, and the display block 3104 is slidably connected to the top surface inside the cavity. A movable block 3105 is fixedly connected to the bottom of the display block 3104. A display slot is provided on the top of the detection device body 1, and the display slot is connected to the cavity. The inside of the display slot is slidably connected to the display block 3104. A trigger switch 3106 is provided on one side of the movable block 3105, and the trigger switch 3106 is fixedly connected to the cavity. The trigger switch 3106 is electrically connected to an alarm 3107 through a wire, and the alarm 3107 is fixedly connected to the detection device body 1. When the pendulum ball 308 swings under external vibration (when the swing force reaches a certain level and affects the settlement detection data), it will precisely touch the contact block 3101, which is elastically connected to the detection device body 1 via a movable spring. The elastic design of the movable spring ensures that the contact block 3101 can move smoothly with the pendulum ball 308 when it touches the device, and also helps it to quickly return to its original position after the touch, effectively preventing the components from jamming. The limiting groove at the top of the contact block 3101 and the limiting block 3102, which is also elastically connected via a support spring, interact with each other. The insertion mechanism forms a precise movement limiting structure, ensuring smooth displacement of the contact block 3101 when touched by the pendulum ball 308 to transmit vibration signals, and also limiting its movement when it is about to reset, preventing the contact block 3101 from repeatedly wobbling under the continuous force of the pendulum ball 308, thus ensuring the stability of the component operation. The cavity inside the detection device body 1 provides ample rotation space for the moving rod 3103. When the contact block 3101 moves, it pushes the short end of the moving rod 3103, causing the moving rod 3103 to move. 03 rotates around the connection point with the main body 1 of the testing equipment, and then drives the moving block 3105 to move synchronously through the long arm end of the moving rod 3103. The moving block 3105 then pulls the display block 3104 to slide smoothly in the display slot on the top surface of the cavity and the top of the main body 1 of the testing equipment. The staff can intuitively judge the maximum intensity of vibration by the sliding state of the display block 3104. When the vibration intensity is too large and the moving block 3105 moves excessively and touches the trigger switch 3106 fixed in the cavity, the trigger switch 3106 will quickly control the alarm 3107 to sound an alarm through the wire. The alarm 3107 can also remotely remind the user as needed, and promptly remind the staff that the current vibration interference has exceeded the reasonable range. This can not only avoid excessive wear of internal parts of the equipment or transmission distortion caused by strong vibration, but also help the staff to quickly take vibration reduction measures, reduce the interference of vibration on the pile foundation settlement test data, improve the controllability of the test process and the accuracy of the data, and at the same time ensure the stable operation life of the equipment in complex vibration environment. The display block 3104 is slidably connected to a positioning block 4 on its outer side, and the positioning block 4 is elastically connected to the inside of the display slot via a moving spring (the moving spring is not shown in the figure). A pushing block 5 is fixedly connected to one side of the positioning block 4, and the pushing block 5 is slidably connected to the limiting block 3102. The positioning block 4 on the outer side of the display block 3104 is elastically connected to the inside of the display slot via a moving spring, which can stably position the display block 3104, preventing it from sliding randomly in the non-working state and affecting the display accuracy. It can also ensure that the display block 3104 maintains its position after vibration, allowing the staff to intuitively obtain accurate vibration feedback information. The pushing block 5 on one side of the positioning block 4 is slidably connected to the limiting block 3102. When the touch block 3101 is touched by the pendulum ball 308 and moves, it will push the limiting block 3102 to move upward. Position block 3102 synchronously drives push block 5 to move, and push block 5 in turn drives positioning block 4 to overcome the spring force of the moving spring and release the positioning restriction on display block 3104, so that display block 3104 can flexibly and smoothly follow the moving rod 3103 to move synchronously. Then limit block 3102 resets and no longer pushes push block 5. Push block 5 and positioning block 4 also reset under the action of their respective connecting springs, and push and position the outer side of display block 3104 again. This effectively avoids jamming during component linkage, ensures the continuity and reliability of transmission between components of vibration display assembly 310, and allows staff to grasp the impact of vibration on detection work in a timely manner. After viewing the data of display block 3104, users can manually move positioning block 4 to unlock and reset display block 3104. Among them, a movable block 6 is fixedly connected to one side of the touch block 3101, and a magnetic shielding block 7 is fixedly connected to one side of the movable block 6. A magnetic block 8 is provided at the bottom of the magnetic shielding block 7, and the magnetic block 8 is magnetically connected to the pendulum ball 308. A magnetic shielding box 9 is fixedly connected to the bottom of the magnetic block 8, and the magnetic shielding box 9 is slidably connected to the magnetic shielding block 7. The magnetic shielding box 9 is also fixedly connected to the detection device body 1. A magnetic shielding plate 10 is slidably connected to the top of the magnetic shielding box 9, and the magnetic shielding plate 10 is elastically connected to the magnetic shielding box 9 by a magnetic shielding spring (the magnetic shielding spring is not shown in the figure). The movable block 6 is linked with the touch block 3101 and moves with the touch block 3101. The movement of 101 is synchronized. The magnetic shielding block 7 fixed on one side can be flexibly adjusted relative to the magnetic force of the magnetic block 8 exposed in the magnetic shielding box 9, so as to control the magnetic force according to the swing amplitude of the pendulum ball 308. During the movement of the contact block 3101, the size of the magnetic shielding range is precisely controlled. The magnetic connection between the magnetic block 8 and the pendulum ball 308 can effectively limit the swing amplitude of the pendulum ball 308, accelerate the stopping speed of the pendulum ball 308 after the vibration stops, and avoid the accuracy of subsequent detection actions being affected by the continuous shaking of the pendulum ball 308. The magnetic block 8 is fixed inside the magnetic shielding box 9 of the detection device body 1. The magnetic shielding box 9 can not only stabilize The fixed magnetic block 8 also provides good magnetic isolation, preventing the magnetic field of the magnetic block 8 from spreading and interfering with the normal operation of other precision components of the equipment. The magnetic shielding plate 10, which is slidably connected to the top of the magnetic shielding box 9, is elastically connected to the magnetic shielding box 9 through a magnetic shielding spring. It has both an automatic reset function and can flexibly adjust the magnetic field coverage range of the magnetic block 8 in conjunction with the pushing action of the pendulum ball 308 on the magnetic shielding plate 10. It is worth noting that the magnetic shielding plate 10 includes two sets of push plates, one upper and one lower, which are fixed to its top. The lower push plate is fixedly connected to the magnetic shielding plate 10 and is rotatably connected to the upper push plate through a torsion spring. When the pendulum ball 308 moves away from the magnetic shielding plate 10, the magnetic shielding plate 10 can be adjusted. When the contact block 3101 swings in the direction of the contact block, it will push the upper push plate to rotate, thereby avoiding obstruction to the movement of the pendulum. When the pendulum 308 swings in the direction of the contact block 3101, it will drive the lower push plate to move through the upper push plate, thereby driving the magnetic shielding plate 10 to move and open its bottom gap. At this time, the magnetic force of the magnetic block 8 can apply a corresponding magnetic attraction to the pendulum 308 through the opening adjusted by the magnetic shielding block 7, thereby achieving precise limitation of the swing amplitude of the pendulum. This structure can ensure that the pendulum 308 always swings within a reasonable range and prevent the mechanism from going out of control due to excessive swing. The magnetic shielding plate 10 has a lifting block 11 on one side, with one side of the lifting block 11 inclined. The lifting block 11 is elastically connected to the detection device body 1 via a compression spring. A friction box 12 is located at the bottom of the lifting block 11 and is fixedly connected to the detection device body 1. The friction box 12 provides controllable frictional damping during the resetting process of the lifting block 11, smoothly controlling its resetting speed, avoiding component collisions or misalignment caused by resetting impact, and ensuring that the vibration triggering mechanism stably resets to the standby state. During the sliding process, the magnetic shielding plate 10 contacts the lifting block 11, which is inclined on one side. The inclined structure guides the lifting block 11 to move downward smoothly. The lifting block 11 is elastically connected to the detection device body 1 via a compression spring. The elastic potential energy of the spring provides sufficient power for its reset, ensuring that it can reset quickly and smoothly after being subjected to force; the friction box 12 at the bottom of the lifting block 11 is fixedly connected to the detection equipment body 1, and can generate stable frictional damping when the lifting block 11 moves down. As it can move stably under the push of the magnetic plate 10, its reset speed is precisely controlled when the lifting block 11 resets; when the lifting block 11 resets to a certain position and disengages from the magnetic plate 10, it will generate an upward pushing force under the action of the compression spring, which will instantly push the limit block 3102 to move slightly upward, so that it is disengaged from the insertion state with the top limit groove of the contact block 3101, releasing the limit constraint on the contact block 3101, and allowing the contact block 3101 to quickly reset to the initial working position under the elastic action of the movable spring; A vibration counter 13 is installed on one side of the contact block 3101 and is fixedly connected to the cavity. The vibration counter 13 records the number of times the contact block 3101 is touched by the pendulum ball 308, quantifies the frequency of vibration events, provides data support for analyzing the persistence and regularity of vibration interference, and assists in judging the stability of the monitoring environment. The vibration counter 13, fixedly connected to the cavity, is located on one side of the contact block 3101. When the pendulum ball 308 is vibrated by external vibration and touches and moves the contact block 3101, the vibration counter 13 accurately records the number of vibrations each time, providing the staff with an intuitive and quantitative count of vibration interference frequency. According to this data, staff can accurately analyze the actual impact of vibration on pile foundation settlement detection, avoiding subjective judgments based solely on experience. This effectively solves the problem that traditional detection equipment cannot statistically analyze vibration interference frequencies, making it difficult to scientifically assess the reliability of monitoring data. Furthermore, through quantified vibration frequency data, staff can further determine the impact range and duration of the vibration source, providing a strong basis for timely and targeted vibration reduction measures. This reduces vibration interference with detection data, improves the credibility and accuracy of monitoring results, provides more comprehensive reference support for engineering pile foundation stability assessment, and ensures the accuracy and rigor of engineering safety decisions. See attached document Figure 1-13The motion indicator component 311 is used to convert the rotational motion of the transmission gear 304 into fluid pressure changes and visually display its amplitude to provide visual feedback on the equipment's operating status. It includes a conveying ring 3111, with a movable groove inside. A pressing block 3112 is slidably connected inside the movable groove. A rotating ring 3113 is fixedly connected to one side of the pressing block 3112 and is fixedly connected to the transmission gear 304. The top of the conveying ring 3111 is connected to a liquid storage column 3114 via a one-way valve, and the liquid storage column 3114 is fixedly connected to the detection equipment body 1. The internal part of 14 is provided with a squeezing ring 3115. One side of the conveying ring 3111 is connected to a display column 3116 through a one-way valve. The display column 3116 is connected to the liquid storage column 3114 through a one-way control valve. The internal part of the display column 3116 is slidably connected with a moving ring 3117. The moving ring 3117 and the display column 3116 are elastically connected through a compression spring. The top of the moving ring 3117 is detachably connected with a scale plate 3118. The scale plate 3118 and the display column 3116 are slidably connected. The internal part of the movable groove is slidably connected with a stop block 3119. The stop block 3119 is elastically connected to the movable groove through a sealing spring. The conveying ring 3111 and the extrusion block 3112 are used to convert the rotational motion of the transmission gear 304 into fluid pressure. The movement of the extrusion block 3112 in the movable groove drives the fluid to flow in a directional manner, realizing the conversion and transmission of mechanical motion into hydraulic indication. The display column 3116 and the moving ring 3117 are used to push the moving ring 3117 to slide in the transparent display column 3116 through the fluid, driving the scale plate 3118 to move, converting the amplitude and frequency of the transmission gear 304's movement into intuitive visual scale changes, which is convenient for real-time observation and recording on site. The scale plate 3118 has a detachable design to provide quantitative indication scale, and it can be detached for later calibration, replacement or cleaning, ensuring that the indication system maintains its accuracy for a long time and adapts to the calibration requirements of different monitoring scenarios. When the transmission gear 304 rotates, it synchronously drives the rotating ring 3113, which is fixedly connected to it, to rotate. The rotating ring 3113 drives the squeezing block 3112 to slide smoothly in the movable groove of the conveying ring 3111. The squeezing block 3112 then generates uniform pressure on the liquid in the conveying ring 3111. When it moves to one side of the stop block 3119, it can push the stop block 3119 by relying on the inclined surface of the squeezing block 3112. At this time, the liquid is squeezed and can be conveyed to the display column 3116 through the one-way valve. The conveying ring 3111 is connected to the liquid storage column 3114 through the one-way valve. The squeezing ring 3115 in the liquid storage column 3114 is elastically connected by a contact spring. It can release elastic potential energy to replenish the liquid in time when the liquid is consumed, ensuring the continuity of liquid circulation and avoiding interruption or distortion of the action indication due to insufficient liquid. The display column 3116 is controlled by a one-way valve. A closed-loop circulation is formed with the liquid storage column 3114 to ensure the reusability of the liquid. A transparent plate fixed on one side of the display column 3116 provides a clear observation window for the staff. The moving ring 3117, which slides with the liquid, will drive the scale plate 3118, which is detachably connected to the top, to move synchronously. By observing the positional changes of the scale plate 3118, the staff can accurately grasp the amplitude and frequency of the movement of the transmission gear 304. By clearly comparing the data of the scale plate 3118 and the mechanical counter 2, it is possible to determine whether there is a fault or abnormal deviation in any system. This effectively solves the problem that the transmission status is difficult to quantify and observe in traditional testing equipment, avoids the subjective error caused by relying solely on experience, and makes the evaluation of the equipment's working status more scientific and objective. At the same time, the detachable design of the scale plate 3118 facilitates later calibration and maintenance, further improving the accuracy of the indicated data. The scale plate 3118 has a cleaning plate 14 slidably connected to one side, and both sides of the bottom of the cleaning plate 14 are fixedly connected to the display column 3116 via telescopic covers (the telescopic covers are not shown in the figure). A locking block 15 is inserted into one side of the cleaning plate 14, and the locking block 15 is elastically connected to the display column 3116 via a locking spring, and the locking block 15 is slidably connected to the display column 3116. A compression column 16 is elastically connected to the bottom of the cleaning plate 14 via a cleaning spring, and the compression column 16 is fixedly connected to the moving ring 3117. The cleaning plate 14 is used to automatically scrape away dust and stains on the surface of the scale plate 3118 during movement, preventing dust and stains caused by user error. During long-term outdoor monitoring, dust accumulation can cause blurred scales and difficulty in reading. To ensure the clarity and reliability of visually indicated data, a cleaning plate 14, slidably connected to one side of the scale plate 3118, can promptly remove dust and impurities from its surface, preventing dust from obscuring the scale and causing blurred readings. This solves the problem of scale contamination affecting observation accuracy in traditional equipment, ensuring that staff can clearly read the data. The telescopic covers on both sides of the bottom of the cleaning plate 14 are fixedly connected to the display column 3116. These telescopic covers can be replaced according to actual usage needs, extending and retracting synchronously with the movement of the cleaning plate 14. This ensures that the cleaning action of the cleaning plate 14 is not hindered while still providing sufficient visual clarity and reliability. The cleaning plate 14 effectively prevents external dust from entering the display column 3116, protecting precision components such as the liquid moving ring 3117 inside the display column 3116, preventing dust from causing component jamming or corrosion, and extending the service life of the equipment. The locking block 15 of the cleaning plate 14 is elastically connected to the display column 3116 via a locking spring. The bottom of the cleaning plate 14 is elastically connected to the moving ring 3117 via a cleaning spring. When the moving ring 3117 slides with the liquid, it pushes the compression column 16, thereby squeezing the compression spring. At this time, the cleaning plate 14 can be stably held at the bottommost position of the scale plate 3118, ensuring that the scale plate 3118 is fully exposed. The key data at the bottom is always kept clean and clear to avoid affecting the integrity of the overall reading due to dust covering the data at the bottom. When the user needs to observe the scale data, simply push the latch 15 gently to manually reset it after use to disengage it from the cleaning plate 14. The cleaning plate 14 can then move under the elastic action of the cleaning spring, simultaneously cleaning the exposed area of ​​the scale plate 3118, ensuring the clarity of the entire scale plate 3118, allowing the user to accurately obtain the action data of the transmission gear 304, providing reliable visual support for judging the working status of the equipment and assessing engineering safety, and further improving the efficiency and accuracy of the testing work. The top of the compression ring 3115 is magnetically connected to an electromagnetic block 17, and the electromagnetic block 17 is magnetically connected to the compression ring 3115. The electromagnetic block 17 and the compression ring 3115 are also elastically connected by a contact spring. The electromagnetic block 17 is electrically connected to a micro switch 18 via a wire, and the micro switch 18 is fixedly connected to the inside of the display column 3116. The micro switch 18 is also electrically connected to the alarm 3107 via a wire. The linkage mechanism between the electromagnetic block 17 and the micro switch 18 is used to trigger the micro switch 18 when the moving ring 3117 moves to its limit position, automatically activating the electromagnetic block 17 to attract the compression ring 3115 to reset, and simultaneously triggering an alarm signal to realize automatic alarm in abnormal conditions and automatic system reset. The top of the squeezing ring 3115 is magnetically connected to the electromagnetic block 17. The electromagnetic block 17 forms a stable electrical circuit with a micro switch 18 fixed inside the display column 3116 via a wire. When the moving ring 3117 slides to the top of the display column 3116 and touches the micro switch 18, it triggers a multi-component linkage action. The micro switch 18 first controls the electromagnetic block 17 to be energized via a wire. After being energized, the electromagnetic block 17 quickly generates a magnetic force to attract the squeezing ring 3115, causing the squeezing ring 3115 to quickly reset. During the reset process, a pulling force is generated simultaneously, pulling the liquid at its bottom to achieve rapid return. Simultaneously, the microswitch 18 will activate the one-way control valve to ensure smooth switching of liquid circulation. At the same time, the microswitch 18 controls the alarm 3107 through the wire to promptly issue a clear warning signal, reminding the staff that the transmission gear 304 has too large an amplitude of movement, which may indicate abnormal settlement or other abnormalities that affect the detection accuracy. This allows the staff to rush to the site to carry out troubleshooting work as soon as possible and prevent the potential hazards from escalating. The relevant operating data after the one-way control valve is opened will also be remotely fed back to the user in real time, so that even if the user is not at the testing site, they can keep track of the equipment's operating status and abnormal information in a timely manner. It is worth noting that all connections along the liquid flow path are sealed using a sealing structure to prevent leakage, forming a reliable dynamic or static sealing system. This effectively eliminates gas leakage and ensures the pressure stability and energy transmission efficiency of the energy storage system. It is also worth noting that the specific selection of springs and other elastic elements and key components involved in this technical solution should be adapted to actual operating conditions such as pressure, frequency, and load to meet the performance requirements for long-term stable operation (and corresponding components and structures can be replaced or adjusted according to specific usage needs). Furthermore, the sliding and movement of each moving part are achieved through reasonable limiting and guiding structures in existing technologies (not fully shown in the figure) to ensure coordinated function and reliable operation of each mechanism. In addition, conventional protection or additional limiting structures can be added to relevant components according to specific usage environments and requirements. It is also worth noting that the moving ring 311... The alarm threshold triggered when the device moves to the top of the display column 3116 is not determined by the size of a single component, but is related to the design parameters of the entire hydraulic transmission system. Specifically, the threshold depends on the rotational stroke of the extrusion block 3112, the transmission efficiency of the extruded liquid, and the corresponding amplitude of the liquid-driven movement of the moving ring 3117. Therefore, in the actual manufacturing stage, the alarm threshold can be systematically preset and customized according to different engineering monitoring needs by coordinating the stroke of the extrusion block 3112, the internal volume of the conveying ring 3111, the characteristics of the liquid medium, and the matching dimensions of the moving ring 3117 and the display column 3116. This design enables the device to flexibly adapt to the settlement monitoring requirements of various pile foundation projects. Users can set matching alarm thresholds based on specific conditions such as pile type characteristics, allowable settlement standards, and warning levels, thereby significantly improving the targeting, accuracy, and applicability of monitoring and warning.

[0023] Working principle: When in use, first fix the main body 1 of the detection device to the designated position, so that the measuring end of the measuring rod 301 is in close contact with the pile foundation measuring point to ensure accurate capture of the vertical displacement of the pile foundation. At this time, all parts of the device are in the standby state. The settlement pawl 306 is engaged with the ratchet 305 under the elastic action of the settlement pawl spring. The pendulum ball 308 is stationary and vibrating. The pawl 307 is located on one side of the ratchet 305 under the pull of the pull spring and is not yet engaged with the ratchet 305. The mechanical counter 2 is zeroed. The liquid in the liquid storage column 3114 is sufficient. The squeezing ring 3115, the moving ring 3117 and the scale plate 3118 are all in the initial position. The contact block 3101 is in the initial position without contact. The limit block 3102 is inserted into the limit groove of the contact block 3101. The positioning block 4 positions the display block 3104. When actual settlement occurs in the pile foundation, the settlement displacement causes the measuring rod 301 to move, which in turn drives the hinged lever 302 to rotate around the hinge point. The lever 302 pulls the rack 303 to move smoothly. The rack 303 meshes with the transmission gear 304 to drive its rotation. The transmission gear 304 synchronously drives the ratchet 305 to rotate. The settlement pawl 306 slides along the tooth surface of the ratchet 305 and adaptively follows through the pawl spring, without obstructing the rotation of the ratchet 305. The vibration pawl 307 does not mesh with the ratchet 305 due to the lack of vibration interference and does not affect the rotation. The ratchet 305 drives the mechanical counter 2 accurately through the transmission rod 309. Record the sedimentation amount; at the same time, the transmission gear 304 drives the rotating ring 3113 to rotate, and the rotating ring 3113 pulls the squeezing block 3112 to slide in the movable groove of the conveying ring 3111 through the connecting rod. The squeezing block 3112 applies pressure to the liquid, and the liquid is transported to the display column 3116 through the one-way valve, which pushes the moving ring 3117 and the scale plate 3118 to move. The staff observes the scale changes through the scale plate 3118 to grasp the amplitude and frequency of the action of the transmission gear 304. The squeezing ring 3115 in the liquid storage column 3114 continuously replenishes the liquid under the action of the resisting spring, ensuring the stable operation of the action indicator component 311. When external vibration occurs, the vibration is transmitted to the equipment body, causing the pendulum ball 308 to swing. The pendulum ball 308 drives the vibration pawl 307 to move laterally and deeply engage with the tooth groove of the ratchet 305 via the swing arm, forming a bidirectional engagement with the settling pawl 306, locking the ratchet 305 to prevent the vibration displacement from being recorded. When the pendulum ball 308 swings, it touches the touch block 3101. The touch block 3101 moves against the elastic force of the movable spring, pushing the limit block 3102 to disengage from the limit groove. The limit block 3102 pushes the push block 5 to move, and the push block 5 drives the positioning block 4 to move, releasing the positioning of the display block 3104. At the same time, the touch block 3101 pushes the moving rod 3103 to rotate. The moving rod 3103 drives the moving block 3105 and the display block 3104 to slide. The operator judges the maximum intensity of the vibration by the sliding distance of the display block 3104. Subsequently, the limit block 3102 and the positioning block 4 will reset under the action of their respective connecting springs. The positioning block 4 can be reset. The display block 3104 is positioned and can display the maximum vibration amplitude for easy observation by the user. The vibration counter 13 records the number of touches and quantifies the influential vibration frequency. The movement of the touch block 3101 also drives the movable block 6 and the magnetic block 7 to move and open the magnetic box 9. When the swing force of the pendulum 308 reaches a certain level, it can push the magnetic plate 10 to slide, exposing the magnetic block 8. The magnetic block 8 can generate a magnetic attraction force on the pendulum 308, accelerating the pendulum 308 to stop swinging. The magnetic plate 10 contacts and pushes the lifting block 11 to move down. Then, the magnetic plate 10 can quickly reset under the action of the magnetic spring. The friction box 12 generates damping to control the reset speed. The lifting block 11 moves up under the action of the compression spring and pushes the limit block 3102 to move up by its reset pushing force. Then, the limit block 3102 resets again under the action of the support spring. When the limit block 3102 is pushed, the touch block 3101 also resets synchronously under the action of the movable spring. When the transmission gear 304 moves too much, the moving ring 3117 slides to the top of the display column 3116 and touches the micro switch 18. The micro switch 18 controls the solenoid block 17 to be energized through the wire and opens the one-way control valve. The solenoid block 17 attracts and squeezes the ring 3115 to reset, so that the liquid flows back to the storage column 3114 through the one-way control valve to achieve circulation. At the same time, the alarm 3107 is controlled to sound an alarm to remind the staff that there is abnormal settlement or strong vibration. The operation of the one-way control valve is existing technology, and its data can be remotely fed back through existing controllers, etc. When the moving ring 3117 slides, the cleaning plate 14 on one side of the scale plate 3118 is elastically connected to the moving ring 3117 through the compression column 16, and is kept at the bottom of the scale plate 3118 to ensure that the key scale is clean. When the entire scale plate 3118 needs to be cleaned, the locking block 15 is pushed to disengage, and the cleaning plate 14 slides to clean the dust under the action of the cleaning spring, which is convenient for the user to observe. In practical applications, this device achieves continuous and stable monitoring of pile foundation settlement through the aforementioned mechanical and structural linkage. Its core lies in its ability to intelligently distinguish between settlement and vibration: the transmission mechanism records smoothly during actual settlement, while automatically locking and providing feedback on the status during vibration interference. The entire mechanism ensures data accuracy while possessing good environmental adaptability and operational visibility, providing a reliable and intuitive solution for settlement monitoring on engineering sites.

[0024] S01: Securely install the main body 1 of the testing equipment in a location near the pile foundation that is not easily disturbed by direct disturbance, and level the base surface; ensure that the measuring end of the measuring rod 301 is in close and perpendicular contact with the measuring point of the pile foundation and fix it; check and confirm that the mechanical counter 2 and each transmission component are in the initial working state; S02: When the pile foundation experiences actual settlement, the measuring rod 301 moves vertically, driving the transmission gear 304 to rotate via the lever 302 and rack 303; the transmission gear 304 drives the ratchet 305 to rotate in one direction via the overpressure clutch, and drives the mechanical counter 2 to accumulate and record the settlement amount via the transmission rod 309. S03: When the transmission gear 304 rotates, it drives the rotating ring 3113 and the extrusion block 3112 to rotate, pressing the fluid into the display column 3116; the fluid pushes the moving ring 3117 and the scale plate 3118 to move upward, visually displaying the transmission action amplitude. This indicated value can be compared with the data recorded by the mechanical counter 2 to determine whether any system has a fault or abnormal deviation. S04: When external vibration is transmitted to the equipment, the pendulum ball 308 swings and drives the vibration pawl 307 to move laterally; the vibration pawl 307 engages with the tooth groove of the ratchet 305, forming a bidirectional lock with the settling pawl 306, preventing the ratchet 305 from rotating and avoiding misrecording of vibration displacement; S05: When the pendulum ball 308 swings to the threshold, it touches and pushes the touch block 3101; the touch block 3101 drives the display block 3104 to slide through the moving rod 3103, and its position reflects the vibration intensity. If the vibration intensity is too high, when the moving block 3105 touches the trigger switch 3106, the alarm 3107 will immediately issue an alarm and remotely remind the user; the vibration counter 13 will synchronously record one threshold vibration. S06: When the touch block 3101 moves, it drives the magnetic isolation mechanism to adjust the magnetic force and accelerate the pendulum ball 308 to stop; then the mechanism is linked to release the limit block 3102 from limiting the touch block 3101, and the touch block 3101 returns to the initial position under the action of the movable spring. S07: When the transmission amplitude reaches the threshold or is abnormal, the moving ring 3117 moves to the top and triggers the micro switch 18. The electromagnetic block 17 is energized to attract and squeeze the ring 3115 to reset, causing the fluid in the indicating system to flow back. At the same time, the alarm 3107 is activated, issuing an abnormal alarm and remotely reminding the user. S08: During regular inspections, push the card block 15 to make the cleaning plate 14 slide along the surface of the scale plate 3118 to remove accumulated dust; read the cumulative settlement value of the mechanical counter 2 on site, obtain the historical maximum vibration intensity through the position of the display block 3104, and combine it with the count value of the vibration counter 13 to comprehensively evaluate the stability of pile foundation settlement and the impact of external vibration environment.

The micro switch (18) is fixedly connected to the inside of the display column (3116), and the micro switch (18) is electrically connected to the alarm (3107) via a wire.

10. A testing method for a pile foundation settlement testing device used in engineering testing, applied to any one of the pile foundation settlement testing devices used in engineering testing according to claims 1 to 9, characterized in that, The method includes: S01: Securely install the main body (1) of the testing equipment in a location near the pile foundation that is not easily disturbed by direct disturbance, and level the base surface; make the measuring end of the measuring rod (301) in close and vertical contact with the measuring point of the pile foundation and fix it; check and confirm that the mechanical counter (2) and each transmission component are in the initial working state; S02: When the pile foundation experiences actual settlement, the measuring rod (301) moves vertically and drives the transmission gear (304) to rotate through the lever (302) and rack (303); the transmission gear (304) drives the ratchet (305) to rotate in one direction through the overpressure clutch, and drives the mechanical counter (2) to accumulate and record the settlement through the transmission rod (309); S03: When the transmission gear (304) rotates, it drives the rotating ring (3113) and the extrusion block (3112) to rotate, and presses the fluid into the display column (3116); the fluid pushes the moving ring (3117) and the scale plate (3118) to move upward, and intuitively displays the transmission action amplitude. This indicated value can be compared with the data recorded by the mechanical counter (2) to determine whether any system has a fault or abnormal deviation. S04: When external vibration is transmitted to the equipment, the pendulum ball (308) swings and drives the vibration pawl (307) to move laterally; the vibration pawl (307) engages in the tooth groove of the ratchet (305) and forms a two-way lock with the sinking pawl (306), preventing the ratchet (305) from rotating and avoiding misrecording of vibration displacement; S05: When the pendulum ball (308) swings to the threshold, it touches and pushes the touch block (3101); the touch block (3101) drives the display block (3104) to slide through the moving rod (3103), and its position reflects the vibration intensity. If the vibration intensity is too high, when the moving block (3105) touches the trigger switch (3106), the alarm (3107) will immediately sound an alarm and remotely remind the user; the vibration counter (13) records one threshold vibration at the same time. S06: When the touch block (3101) moves, it drives the magnetic isolation mechanism to adjust the magnetic force and accelerate the pendulum ball (308) to stop. Then the mechanism is linked to release the limit block (3102) from the limit of the touch block (3101), and the touch block (3101) is reset to the initial position under the action of the movable spring. S07: When the transmission amplitude reaches the threshold or is abnormal, when the moving ring (3117) moves to the top and triggers the micro switch (18), the electromagnetic block (17) is energized to attract and squeeze the ring (3115) to reset, so that the fluid in the indicating system flows back; at the same time, the alarm (3107) is activated, an abnormal alarm is issued, and the user is remotely reminded. S08: During regular inspections, push the card block (15) to make the cleaning plate (14) slide along the surface of the scale plate (3118) to remove accumulated dust; read the cumulative settlement value of the mechanical counter (2) on site, obtain the historical maximum vibration intensity through the position of the display block (3104), and combine the count value of the vibration counter (13) to comprehensively evaluate the stability of pile foundation settlement and the impact of external vibration environment.
