A test rod 407 is fixedly installed at the center. During the standard penetration test, the support platform 1 provides a stable foundation support for the entire device. The sleeve 2 located at the center of the support platform 1 provides a straight and stable running channel for the test rod 4. The test rod 4 is embedded in the sleeve 2 and cooperates with the sliding block 401 through the sliding thread 403 at the bottom of the test rod 4. When the sliding block 401 moves, the sliding block 401 moves on the sliding thread 403, so that the external sensing platform 406 and the test rod 407 at the bottom center can work in a predetermined manner to complete the data acquisition and testing tasks.

[0022] Please see Figures 2-4 In this embodiment, a pressure sensor 408 is installed at the bottom of the experimental rod 407. The pressure sensor 408 is a PX2AA0250SG2A3. A power supply 409 is installed at the top of the sensing platform 406. The top of the sensing platform 406 has a mounting slot for installing the power supply 409. A data transmitter 410 is installed above the power supply 409 on the sensing platform 406. The data transmitter 410 is an ME909s-821. The power supply 409 installed at the top of the sensing platform 406 provides stable power support for the entire sensing system, ensuring that the data transmitter 410 can work continuously and stably without being limited by external power supply conditions, thereby ensuring the continuity and reliability of test data. A drive motor 405 is installed on the side of the sliding block 401 away from the sensing platform 406. Both the data transmitter 410 and the pressure sensor 408 are electrically connected to the power supply 409. The electrical connection between the data transmitter 410 and the power supply 409 enables the stable and efficient timely transmission of the data collected by the pressure sensor 408, facilitating real-time monitoring and analysis by the staff.

[0023] Please see Figures 2-4In this embodiment, a rubber sleeve 402 is fitted over the top of the detection rod 4, and a connection hole 404 is provided at the top of the detection rod 4. The rubber sleeve 402 can provide good protection for the top of the detection rod 4, reducing the collisions and wear that may occur during handling, storage and use, and extending the service life of the detection rod 4. Three sets of fixing plates 106 are installed in a ring around the outside of the support platform 1. A rotating rod 105 is installed at the center of each fixing plate 106, and a support rod 101 is fitted over each rotating rod 105. The three sets of fixing plates 106 installed in a ring around the outside of the support platform 1, as well as the rotating rod 105 and the support rod 101 that cooperate with them, can provide additional support for the entire device, enhance the stability of the device during operation, and reduce shaking and displacement. The design of the rotating rod 105 allows the support rod 101 to rotate flexibly and adjust its angle to adapt to different working sites and terrain conditions, ensuring optimal support effect.

[0024] Please see Figures 2-3 In this embodiment, each support rod 101 has a rotating groove 104 through one end for embedding a rotating rod 105. Each support rod 101 has a support column sleeve 102 fitted at its bottom end. Each support column sleeve 102 has an angle adjustment plate 103 installed at its bottom end. Threaded fixing holes are through the corners of the angle adjustment plate 103. Each support column sleeve 102 has a cable fixing post 107 installed on its exterior. The cable fixing post 107 has a through-hole ring for threading a cable. The angle adjustment plate 103 allows for more precise adjustment and fixing of the support angle of the support rod 101. The threaded fixing holes can lock the adjusted angle, ensuring that the angle remains unchanged during operation, thus providing more reliable support for the device. The cable fixing posts 107 outside the support column sleeve 102... The mounting platform 3 includes a perforated ring for easy cable threading, which further secures the device to the ground or other fixed points, enhancing its stability in harsh environments or under strong external forces and improving operational safety. A data board 301 is mounted on the top of the mounting platform 3, with a level 302 mounted on its exterior. A connecting post 303 is mounted on the bottom of the mounting platform 3, connecting to the connecting hole 404 at the top of the detection rod 4. The level 302 on the exterior of the data board 301 monitors the device's horizontal position in real time, ensuring the test is conducted under level conditions, thereby improving the accuracy and reliability of the test results. The connecting post 303 at the bottom of the mounting platform 3 connects to the connecting hole 404 at the top of the detection rod 4, forming a stable connection structure and reducing errors and malfunctions caused by loose connections during testing.

[0025] During operation, when performing standard penetration testing (SPT), the device is first placed in the predetermined test position. The support rod 101, fitted onto the rotating rod 105 of the three sets of fixed clamping plates 106 ring-shaped on the outside of the support platform 1, has its angle adjusted via the rotating groove 104. The angle is then fixed using the angle adjustment plate 103 and threaded fixing holes. Simultaneously, a rope can be threaded through the rope fixing post 107 outside the support post sleeve 102 to further secure the device to the ground, ensuring its stability. The detection rod 4 is embedded in the sleeve 2 at the center of the support platform 1, and its top connection hole 404 connects to the connecting post 303 at the bottom of the mounting platform 3. The data board 301 at the top of the mounting platform 3 is ready to receive and display test data. The external level 302 ensures the device is level. The power supply 409 in the sensing platform 406 on the sliding block 401 supplies power to the data transmitter 410 and the pressure sensor 408. The drive motor 405 drives the sliding block 401 to move on the sliding thread 403 at the bottom of the detection rod 4. After the test starts, the detection rod 4 is inserted under the guidance of the sleeve 2. During the insertion process, the pressure sensor 408 collects data. This data is transmitted to the data board 301 for display and recording through the data transmitter 410. The rubber sleeve 402 on the top of the detection rod 4 provides protection. Throughout the test, all components work together to ensure the accuracy of the test data and the stable operation of the device.

[0026] Through the above steps, during the standard penetration test, the support platform 1 provides a stable foundation support for the entire device. The sleeve 2 located at the center of the support platform 1 provides a straight and stable running channel for the test rod 4. The test rod 4 is embedded in the sleeve 2. It cooperates with the sliding block 401 through the sliding thread 403 at the bottom of the test rod 4. When the sliding block 401 moves, it moves on the sliding thread 403, so that the external sensing platform 406 and the test rod 407 at the bottom center can work in a predetermined manner to complete the data acquisition and testing tasks.
