  • Gravity type pore pressure dynamic penetration device for shallow layer seabed soil
    Patent number: 9777452
    Abstract: A gravity-type pore pressure dynamic penetration device for exploration of shallow-layer seabed soil includes a third drop hammer, a second drop hammer, a first drop hammer, a stable empennage, and a probe rod which are sequentially arranged from top to bottom. A sidewall friction sleeve is arranged outside a probe rod lower cylinder. A friction sleeve sensor is provided on an inner sidewall of the sidewall friction sleeve. A first pore water pressure sensor, a conical tip pressure sensor, a temperature compensation sensor, and an inclinometer sensor are provided in the middle of the probe rod lower cylinder. A second pore water pressure sensor and an acceleration sensor are provided in the middle of a probe rod upper cylinder. The tail portion of the probe rod, that is, the upper portion of the probe rod upper cylinder is connected to the stable empennage.

  • GRAVITY TYPE PORE PRESSURE DYNAMIC PENETRATION DEVICE FOR SHALLOW LAYER SEABED SOIL
    Publication number: 20170233968
    Abstract: A gravity-type pore pressure dynamic penetration device for exploration of shallow-layer seabed soil includes a third drop hammer, a second drop hammer, a first drop hammer, a stable empennage, and a probe rod which are sequentially arranged from top to bottom. A sidewall friction sleeve is arranged outside a probe rod lower cylinder. A friction sleeve sensor is provided on an inner sidewall of the sidewall friction sleeve. A fast pore water pressure sensor, a conical tip pressure sensor, a temperature compensation sensor, and an inclinometer sensor are provided in the middle of the probe rod lower cylinder. A second pore water pressure sensor and an acceleration sensor are provided in the middle of a probe rod upper cylinder. The tail portion of the probe rod, that is, the upper portion of the probe rod upper cylinder is connected to the stable empennage.
