Description

Technical Field

[0001] This application relates to the field of engineering testing technology, and in particular to a pile foundation testing system, method, electronic device and storage medium. Background Technology

[0002] Bridges are an important component of urban road transportation construction, and pile foundations, as the supporting structure of bridges, have a significant impact on the safety and reliability of bridges. Therefore, it is essential to inspect the quality of pile foundations during bridge construction.

[0003] Currently, pile foundation testing generally uses drilling sampling or ultrasonic testing methods. However, these methods have certain limitations. For example, drilling sampling needs to be carried out after the pile foundation construction is completed, which cannot detect problems in time. Ultrasonic testing is affected by the pile foundation surface: during ultrasonic testing, the test probe needs to contact the surface of the pile foundation, but the unevenness of the pile foundation surface affects the propagation of ultrasonic waves, thus affecting the testing accuracy.

[0004] Therefore, it is necessary to develop a new monitoring technology to improve the accuracy of pile foundation testing, thereby enhancing the safety and reliability of bridges. Summary of the Invention

[0005] This application provides a pile foundation testing system, method, electronic device, and storage medium, which improves the accuracy of pile foundation testing.

[0006] The purpose of this application is to provide a pile foundation testing system.

[0007] The aforementioned objective of this application is achieved through the following technical solution: A pile foundation testing system, applied to pile foundations, includes a monitoring mechanism and a treatment mechanism; The monitoring mechanism includes a frame, clamps, and a conveyor belt. The frame is used to install the clamps, the inner curved surface of which contacts the pile foundation, and the outer curved surface of which is slidably connected to the conveyor belt. A motor is mounted on the frame to drive the conveyor belt to reciprocate on the outer curved surface of the clamps. An anode potentiometer is mounted on one end of the conveyor belt to collect the first state parameters of the pile foundation. A cable is also mounted on the frame, and a cathode potentiometer is mounted on the movable end of the cable to collect the second state parameters of the pile foundation. A distance sensor is also mounted on the movable end of the cable to measure the height of the pile foundation and generate a height parameter. The processing mechanism is communicatively connected to the anode potentiometer, the cathode potentiometer, and the ranging sensor. The processing mechanism is used to receive the first state parameter, the second state parameter, and the height parameter, and to generate multiple sets of state parameters based on the first state parameter and the second state parameter. The processing mechanism is also used to input the height parameter and the multiple sets of state parameters into the calculation model to generate a health score.

[0008] By adopting the above technical solution, in the monitoring mechanism: the anode potentiometer is used to detect the first state parameters of the pile foundation, and when the anode potentiometer reciprocates along the outer curved surface of the clamp under the drive of the conveyor belt, it can detect multiple first state parameters. The cathode potentiometer is used to detect the second state parameters of the pile foundation, and the distance sensor is used to detect the height parameter of the pile foundation. In the processing mechanism: the processing mechanism is used to generate multiple sets of state parameters based on the second state parameters and multiple first state parameters, and then calculates a health score based on the height parameter and multiple sets of state parameters. Therefore, this application determines the health status of the pile foundation by judging the potential changes between multiple points on the pile foundation and the height changes of the pile foundation.

A horn-shaped rubber head is provided on the movable end, and a cathode potentiometer is provided inside the rubber head.

[0014] By adopting the above technical solution, when the cable is pulled, the rotating shaft rotates to deform the spring, and when the spring returns to its original position, it will drive the cable back onto the rotating shaft, thereby achieving the purpose of quickly retrieving the cable.

[0015] In a preferred embodiment, the processing mechanism may be further configured to include a differential amplifier, a filter, and a processor. The differential amplifier is communicatively connected to the anode potentiometer, the cathode potentiometer, and the ranging sensor, respectively. The differential amplifier is used to amplify the first state parameter, the second state parameter, and the height parameter. The filter is communicatively connected to the differential amplifier, and the filter is used to filter the first state parameter, the second state parameter, and the height parameter; The processor is communicatively connected to the filter. The processor is used to generate multiple sets of state parameters based on the first state parameter and the second state parameter, and input the height parameter and the multiple sets of state parameters into the calculation model to generate a health score.

[0016] By adopting the above technical solution, firstly, the first state parameter, the second state parameter, and the height parameter are all processed by differential amplifiers and filters, which makes the accuracy of the first state parameter, the second state parameter, and the height parameter received by the processor higher, thereby providing technical support for the processor to calculate a more accurate health score.

[0017] The second objective of this application is to provide a method for testing pile foundations.

[0025] The fourth objective of this application is achieved through the following technical solution: A computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements any of the above-described pile foundation testing methods.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. First, the pile foundation testing system of this application comprises two parts: a monitoring mechanism and a processing mechanism. During measurement, in the monitoring mechanism: an anode potentiometer is used to detect the first state parameters of the pile foundation, and when the anode potentiometer reciprocates along the outer curved surface of the clamp driven by a conveyor belt, it can detect multiple first state parameters. A cathode potentiometer is used to detect the second state parameters of the pile foundation, while a distance sensor is used to detect the height parameter of the pile foundation. Therefore, the monitoring mechanism can provide data support for the processing mechanism to determine the health status of the pile foundation. 2. In the processing mechanism: First, a differential amplifier and a filter process the first state parameter, the second state parameter, and the height parameter respectively, resulting in higher accuracy of the first state parameter, the second state parameter, and the height parameter received by the processor. Then, the processor generates multiple sets of state parameters based on the second state parameter and multiple first state parameters, and calculates a health score based on the height parameter and multiple sets of state parameters. Therefore, this application determines the health status of the pile foundation by judging the potential changes between multiple points on the pile foundation and the height changes of the pile foundation. By using multiple perspectives as the basis for judging the health of the pile foundation, the accuracy of detecting the quality of the pile foundation is improved. Attached Figure Description

Detailed Implementation

[0032] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] The following is in conjunction with the instruction manual appendix. Figure 1-4 The embodiments of this application will be described in further detail.

[0035] Figure 1 This is a schematic diagram of an exemplary operating environment for an embodiment of this application. (Refer to...) Figure 1 The operating environment includes pile foundation 700 and a pile foundation testing system for detecting the quality of pile foundation 700. The pile foundation testing system includes a monitoring mechanism and a processing mechanism. The monitoring mechanism collects height parameters and multiple sets of status parameters of pile foundation 700. The processing mechanism communicates with the monitoring mechanism. This communication connection can be wired, such as an Ethernet connection; it can also be wireless, such as a Wi-Fi connection or a Bluetooth connection. The specific communication connection method is not limited here. The processing mechanism receives the height parameters and multiple sets of status parameters and calculates the health score of pile foundation 700 based on these parameters, thereby determining the quality of pile foundation 700.

[0036] The monitoring mechanism includes a frame 100 and a clamp 200. The frame 100 includes a bracket 110 and a mounting platform 120. One end of the bracket 110 has a support block 111 for contact with the ground. The support block 111 increases the contact area between the bracket 110 and the ground, improving the stability of the bracket 110. The other end of the bracket 110 is connected to the mounting platform 120, specifically by screw connection or sliding connection. In the screw connection, a threaded hole is made on the bottom of the mounting platform 120, and a threaded hole of the same diameter as the threaded hole on the mounting platform 120 is also made on the side wall of the bracket 110 that contacts the mounting platform 120. During installation, screws are passed through the threaded holes in the bracket 110 and the mounting platform 120 to fix the bracket 110 to the bottom of the mounting platform 120. In the sliding connection configuration, the bracket 110 can be configured as a freely retractable structure, similar to an umbrella handle. A spring-loaded mechanism, similar to that found on an umbrella handle, is installed on the bracket 110 for securing it. During retraction, pressing the spring retracts the bracket 110 back to the bottom of the mounting platform 120, achieving rapid retraction of the bracket 110. The accompanying drawings of this application do not show the specific connection structure between the bracket 110 and the mounting platform 120; in actual use, either the screw connection or the sliding connection described above can be selected.

[0037] Reference Figure 1 , Figure 2 and Figure 3 The mounting platform 120 is hollow, and the hollow space is divided into a first chamber 121 and a second chamber 122 in parallel. The first chamber 121 is close to the pile foundation 700, and a first outlet 1211 is opened on the side wall of the first chamber 121 facing the pile foundation 700. Figure 2 The image is represented by a curve with an arrow. One end of the clamp 200 is connected to the mounting platform 120 through the first outlet 1211, and the other end extends towards the pile foundation 700, with the inner curved surface of the clamp 200 contacting the outer periphery of the pile foundation 700, so that the mounting platform 120 is fixed to one side of the pile foundation 700 through the contact between the clamp 200 and the pile foundation 700. The first chamber 121 is used to install the motor 1212. There are two motors 1212 located in the first chamber 121. The two motors 1212 are arranged side by side and have the same rotation direction and rotation frequency. A conveyor belt 300 is arranged between the two motors 1212. The conveyor belt 300 is sleeved on the clamp 200 through the first outlet 1211, so that the conveyor belt 300 reciprocates on the clamp 200 under the drive of the motor 1212.

[0038] To prevent the conveyor belt 300 from detaching from the clamp 200, a groove 210 is provided on the side wall of the clamp 200 surrounding the pile foundation 700. Figure 1The curves with arrows are used to represent this. A sleeve 220 is disposed inside the chute 210 and is slidably connected to the clamp 200. The outer wall of the sleeve 220 is provided with external threads. The conveyor belt 300 contacts the outer wall of the sleeve 220 and is connected by threads, that is, the conveyor belt 300 is provided with internal threads. The external threads on the sleeve 220 and the internal threads on the conveyor belt 300 cooperate with each other so that when the conveyor belt 300 reciprocates, it drives the sleeve 220 to rotate together, while the clamp 200 remains stationary. This prevents the conveyor belt 300 from falling off and also ensures the stability of the clamp 200, thereby further improving the stability of the mounting platform 120.

[0039] Additionally, a connecting block 310 is provided on the side wall of the conveyor belt 300 away from the sleeve 220. The connecting block 310 is welded to the conveyor belt 300. To ensure the stability of the connecting block 310, the conveyor belt 300 can be made of a rigid material, such as a chain. It should be noted that the connecting block 310 is located in the moving direction of the conveyor belt 300 and at the end that gradually moves away from the first outlet 1211 when the conveyor belt 300 starts. Here, "starting the conveyor belt 300" refers to the moment when the motor 1212 is just powered on and drives the conveyor belt 300 to move. To illustrate the position of the connecting block 310, for example... Figure 3 As shown, if the conveyor belt 300 rotates counterclockwise when it starts, the connecting block 310 is positioned at point A. When the conveyor belt 300 moves, the connecting block 310 moves from point A to point B. If... Figure 3 When the conveyor belt 300 starts, it rotates clockwise. The connecting block 310 is set at point B. When the conveyor belt 300 moves, the connecting block 310 moves from point B to point A. This prevents the connecting block 310 from entering the first chamber 121 and colliding with the motor 1212 in the first chamber 121, thereby ensuring the safety of the monitoring mechanism during operation.

[0040] A mounting clip 320, made of stainless steel, is hinged to the end of the connecting block 310 furthest from the conveyor belt 300. This clip is used to mount the anode potentiometer 400. In use, the mounting clip 320 can be rotated towards the pile foundation 700 to allow the anode potentiometer 400 to contact the pile foundation 700, facilitating the detection of the first state parameter of the pile foundation 700 by the anode potentiometer 400. It should be noted that the first state parameter refers to the potential detected by the anode potentiometer 400 at its detection point, which is the contact point between the anode potentiometer 400 and the pile foundation 700.

[0041] A power module 800 is installed in the second chamber 122. The power module 800 supplies power to the anode potentiometer 400 and the motor 1212. The power module 800 can be a battery. This application does not limit the type of battery, as long as it can be installed in the second chamber 122 and can provide operating voltage to the anode potentiometer 400 and the motor 1212. To facilitate the power module 800 supplying power to the anode potentiometer 400, a third outlet 1227 is provided on the side wall of the second chamber 122 near where the anode potentiometer 400 is located. The third outlet 1227... Figure 3 The curve with an arrow is used to represent this. In practical applications, a cable is connected to the power output terminal of the power module 800, and the other end of the cable is connected to the anode potentiometer 400, so that the power module 800 supplies power to the anode potentiometer 400.

[0042] Additionally, a second outlet 1221 is provided on another side wall of the second chamber 122, and the side wall where the second outlet 1221 is located is opposite to the side wall where the third outlet 1227 is located. The second outlet 1221 is located in... Figure 1 The second chamber 122 is represented by a curve with an arrow. A cable storage assembly is installed on the inner wall of the second chamber 122, comprising a cable reel 1222, a spring 1223, and a cable 1225. The cable reel 1222 is fixed inside the second chamber 122, and a rotating shaft 1224 is mounted on its axis. Both ends of the rotating shaft 1224 are connected to the cable reel 1222 via springs 1223. One end of the cable 1225 is fixedly connected to the rotating shaft 1224, and the other end of the cable 1225 extends outside the second chamber 122 through a second outlet 1221 and is equipped with a flared rubber head 1226. A cathode potentiometer 500 is installed inside the rubber head 1226. Figure 1 The cathode potentiometer 500 is not shown in the diagram; it is only represented by a straight line with an arrow. In use, the rubber head 1226 is placed at the bottom of the pile foundation 700, allowing it to adhere to the pile foundation 700. By freely moving the contact point between the rubber head 1226 and the pile foundation 700, the cathode potentiometer 500 located within the rubber head 1226 can come into contact with the pile foundation 700, thus facilitating the detection of the second state parameter of the pile foundation 700. It should be noted that the second state parameter refers to the potential detected by the cathode potentiometer 500 at its detection point, which is the contact point between the anode potentiometer 400 and the pile foundation 700. During recycling, the rubber head 1226 is pulled out, which reduces the tension on one end of the cable 1225 with the rubber head 1226. At this time, the spring 1223 returns to its original position. When the spring 1223 returns to its original position, it drives the rotating shaft 1224 to rotate, thereby driving the cable 1225 to be recycled onto the reel 1222, thus achieving the purpose of quickly recycling the cable 1225.

[0043] It should be noted that, in order to continuously observe the potential changes at the same location on the pile foundation 700 and ensure the accuracy of the assessment of the pile foundation 700's quality, in actual use, it is necessary to ensure that the points detected by the anode potentiometer 400 in each testing cycle are exactly the same as those detected in the previous testing cycle, while the points detected by the cathode potentiometer 500 in any testing cycle are the same. For this purpose, the starting point of the anode potentiometer 400 can be marked on the pile foundation 700 by painting or labeling. Driven by the conveyor belt 300, the anode potentiometer 400 starts testing from the starting point and sequentially tests all the points detected in the previous testing cycle according to the order and position of the points detected in the previous testing cycle. Similarly, the fixed testing points of the cathode potentiometer 500 are also marked by painting or labeling, and the rubber head 1226 is placed on the fixed testing point in each testing cycle. Therefore, as the detection point of the anode potentiometer 400 changes continuously, the first state parameter detected by the anode potentiometer 400 at each detection point and the second state parameter detected by the cathode potentiometer 500 at a fixed detection point can be combined into multiple sets of state parameters.

[0044] It should also be noted that a distance sensor 600, such as a laser sensor or an infrared distance sensor 600, is installed on the rubber head 1226. The distance sensor 600 is used to measure the height of the pile foundation 700 and generate height parameters. Measuring the height of the pile foundation 700 is important because the pile foundation 700 may drop due to pressure during use, resulting in a lower height. Therefore, measuring the height change of the pile foundation 700 is an important factor in judging its quality. In this example, the specific installation method of the distance sensor 600 is not restricted. In actual use, the distance sensor 600 can be glued to the outer wall of the flared rubber head 1226, or a mounting clip 320 can be hinged to the outer wall of the rubber head 1226, and then the distance sensor 600 can be fixed by the mounting clip 320. Since the rubber head 1226 will be placed at a fixed detection point during testing, placing the distance sensor 600 on the rubber head 1226 can also ensure the accuracy of the measured height change of the pile foundation 700.

[0045] The processing mechanism can be located within the mounting platform 120, such as within the second chamber 122, or independently outside the mounting platform 120, such as at the pile foundation management center. The pile foundation management center refers to the management office that manages the pile foundations 700 and repairs damaged pile foundations 700. Specifically, the processing mechanism includes a differential amplifier, a filter, and a processor, where the processor is a CPU with computing and storage capabilities. The differential amplifier is communicatively connected to the anode potentiometer 400, the cathode potentiometer 500, and the distance sensor 600, respectively, to obtain a first state parameter from the anode potentiometer 400, a second state parameter from the cathode potentiometer 500, and a height parameter from the distance sensor 600. It then amplifies the first state parameter, the second state parameter, and the height parameter before transmitting them to the filter. The filter is communicatively connected to the differential amplifier, and it filters the first state parameter, the second state parameter, and the height parameter before transmitting them to the processor, thereby improving the accuracy of the first state parameter, the second state parameter, and the height parameter obtained by the processor. The processor communicates with the filter. After receiving the first state parameter, the second state parameter, and the height parameter, the processor retrieves the calculation model stored inside it, inputs the first state parameter, the second state parameter, and the height parameter into the calculation model, and the calculation model calculates the health score of the pile foundation 700 based on the first state parameter, the second state parameter, and the height parameter.

[0046] To facilitate the explanation of the processor's processing of the first state parameter, the second state parameter, and the height parameter, this application proposes a pile foundation detection method, such as... Figure 4 As shown, the main process of this method is described below: Step S1: Calculate the first score based on the first state parameter and the second state parameter.

[0047] First, the processor combines the first and second state parameters according to the order in which they are received, forming multiple sets of state parameters. This is because the detection point of the cathode potentiometer 500 remains fixed, so the value of the second state parameter remains constant. Therefore, n sets of state parameters can be formed based on the n received first state parameters, where n ∈ N. * And n≥1. For example, there exists a second state parameter b. When the first state parameter a1 is received at 08:00, the first state parameter a2 is received at 08:01, and the first state parameter a3 is received at 08:02, they are combined to form three sets of state parameters, namely a1-b, a2-b, and a3-b.

[0048] Then, for each set of state parameters, first determine the potential magnitudes of the first and second state parameters. Then, subtract the smaller potential from the larger potential to obtain the actual potential difference of pile foundation 700. The actual potential difference can also be considered as the absolute value of the first state parameter minus the second state parameter. Next, retrieve the initial potential difference, which refers to the potential difference measured before pile foundation 700 was put into use and is stored in the processor. Finally, calculate the potential change rate p = actual potential difference / initial potential difference, and then calculate the score B. i =(1-p i )*100, i∈N * And i≤n, where B i This refers to the score of the i-th group of state parameters, p i It refers to the rate of change of the potential of the i-th group of state parameters.

[0049] Finally, after calculating the score for each set of state parameters, the average of the scores for multiple sets of state parameters is calculated as the final first score for the pile foundation 700.

[0050] Step S2: Calculate the second score based on the height parameter.

[0051] First, retrieve the initial height, which refers to the height measured before the pile foundation 700 was put into use and is stored in the processor. Then, extract the actual height from the height parameters, calculate the height change rate q = actual height / initial height, and then calculate the second score F2 = (1-q)*100.

[0052] Step S3: Calculate the health score based on the first score and the second score.

[0053] After obtaining the first and second scores, the health score S = F1 + F2 is calculated. In this example, a warning score and an alarm score are set, with the warning score being higher than the alarm score. When the health score is higher than the warning score, it indicates that the changes in pile foundation 700 are within the normal fluctuation range, and the higher the health score, the better the quality of pile foundation 700. When the health score is lower than the warning score but higher than the alarm score, pile foundation 700 with a health score lower than the warning score but higher than the alarm score is marked as a key focus pile foundation for continuous monitoring. When the health score is lower than the alarm score, pile foundation 700 with a health score lower than the alarm score is marked as a shutdown pile foundation, meaning it needs to be shut down to prevent damage to pile foundation 700 from posing a hazard to pedestrians or vehicles crossing the bridge.

[0054] Therefore, the implementation principle of the pile foundation detection method in this application embodiment is as follows: First, the monitoring mechanism is installed: the motor 1212 is started, and the conveyor belt 300 reciprocates around the pile foundation 700 under the drive of the motor 1212. During the movement of the conveyor belt 300, the mounting clamp 320 is rotated towards the pile foundation 700 to place the anode potentiometer 400 on the pile foundation 700, thereby enabling the anode potentiometer 400 to detect the first state parameter of the pile foundation 700 at the detection point. At the same time, the rubber head 1226 is pulled by the second outlet 1221, and the rubber head 1226 is adsorbed on the fixed detection point of the pile foundation 700. The cathode potentiometer 500 located in the rubber head 1226 detects the second state parameter of the fixed detection point. During the rotation, the anode potentiometer 400 and the cathode potentiometer 500 jointly generate multiple sets of state parameters. In addition, the distance sensor 600 is also activated to measure the descent height of the pile foundation 700 to generate a height parameter.

Based on the health score, the health status of the pile foundation 700 is obtained.
