The invention discloses a
seabed automatic drilling type piling device and method. The
seabed automatic drilling type piling device comprises an expansion fixing module, an upper anchoring module, a lower anchoring module, a
chip removal module and a drilling module, and a
mooring rope can be dragged to automatically
drill into a
seabed rock stratum to achieve anchoring; the drilling module can
drill the seabed rock stratum; the
chip removal module can automatically transfer rock chips to the rear of the device, so that efficient
chip removal and drilling are realized; the upper anchoring module and the lower anchoring module play a role of fixing the device during drilling, and can assist in anchoring after drilling to a specified anchoring depth; when an
extrusion head is subjected to upward pulling force applied by the
mooring rope, an expansion cover in the expansion fixing module deforms and opens under the action of the
extrusion head, the
friction force between the expansion cover and the rock chips is increased, and therefore reliable anchoring is achieved. The problems of insufficient seabed shallow non-diagenetic piling depth and unreliable anchoring are mainly solved, high
automation and controllable piling depth are realized, and the seabed automatic drilling type piling device and method are suitable for piling operation requirements of different water depths and various seabed
lithology.
