Title:
SELF-DRIVING SENSOR CAPABLE OF BEING USED FOR TESTING IN REAL TIME LATERAL RESISTANCE AND END RESISTANCE OF MARINE PIPE PILE, AND TESTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/081748
Kind Code:
A1
Abstract:
A self-driving sensor capable of being used for testing in real time the lateral resistance and end resistance of a marine pipe pile, and a testing device, the self-driving sensor comprising a self-driving sensor which is used for measuring lateral resistance and a self-driving sensor which is used for measuring end resistance; and a sensor-based testing device comprises a TENG friction resistance measurement module (1), a soil plug generation height measurement module (2), a friction pile main body (4) and a TENG end resistance measurement module (3). The testing device uses triboelectrification and electrostatic induction principles to introduce a TENG into the measurements of friction resistance and end resistance of a pipe pile. The lateral resistance and end resistance of inner and outer walls of a pipe pile under penetration and long-term service may be directly and accurately measured without the need for external energy, and the effect of soil plug generation height on the pile side friction resistance and the bearing force of a pile foundation may be evaluated.
