HOLE PRESSURE PROBE ROD APPARATUS THAT CAN FOLD AUTOMATICALLY AND WORKING METHOD THEREFOR

WIPO Patent Application WO/2023/051834

A1

The present invention provides a hole pressure probe rod apparatus that can fold automatically, comprising a support system, a penetrating system, and a measurement system. Directed towards certain problems in the current research and development of seabed pore water pressure monitoring apparatus under extreme storm conditions, a set of hole pressure probe rod apparatus that can fold automatically is designed. The described apparatus has a simple structure, a large penetration depth, a small size, and other characteristics, and can perform long-term in-situ stable monitoring on the pore water pressure at the interior of a seabed soil layer in the range of 0-5 m. By means of the technical solution of the present invention, the difficulty of monitoring the pore water pressure of a vertical section of the seabed is solved. The problem that the overall device is huge and stability is low due to a pore water pressure probe rod being overly long is solved. The problem that an observation apparatus is difficult to recover due to burying is solved.
