Auto-collapsible pore pressure probe device
A recently filed patent (Publication Number: US20230203944A1) describes an auto-collapsible pore pressure probe device. The device consists of a support system, a penetration system, and a measurement system. The support system includes a first support frame, a second support frame, four separation mechanisms, an upper support leg, a lower support leg, an upper clamping slot, a lower clamping slot, a support base, and a third support frame. The first support frame is octagonal and serves as the main support mechanism, while the second support frame supports the penetration system. The four separation mechanisms are located at the bottom of the first support frame and include support leg ring clamps, support fixing nuts, and support leg fixing bolts. The penetration system includes a rod storage wheel, a rod storage wheel motor, a tightening mechanism, a penetration drive motor, primary transmission gears, fixing brackets, and friction wheels. The measurement system consists of a modular pore pressure probe, a control cabinet, a pore pressure static penetration test (CPTU) probe, a pore pressure sensor, a probe connector, a displacement sensor, and a deck unit.
The first support frame is made of welded hollow stainless-steel cylindrical tubes, and the support base consists of four circular plates. The four separation mechanisms include support leg fixing nuts, support leg fixing bolts, upper clamping slots, and lower clamping slots. The control cabinet is equipped with a battery, a data acquisition instrument, and a control panel. The probe connector is fixed to the bottom end of each section of the modular pore pressure probe and includes a connector external thread, a fastening strip, and a connecting bolt. The operation method of the device involves connecting the data transmission and power supply cable, deploying the device on the seabed surface, and performing a penetration operation using the penetration system. The device allows for in-situ detection and data storage.
In summary, the auto-collapsible pore pressure probe device described in the patent provides a comprehensive solution for measuring pore pressure in soil. The device includes a support system, a penetration system, and a measurement system, all designed to work together seamlessly. The device is constructed using high-quality materials such as stainless steel and includes various mechanisms and components to ensure accurate and efficient measurements. The operation method of the device involves deploying it on the seabed surface and performing a controlled penetration operation. Overall, this patent presents an innovative and practical solution for pore pressure measurement in soil.
