Title:
SEABED TYPE STATIC CONE PENETRATION APPARATUS AND PENETRATION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/099082
Kind Code:
A1
Abstract:
Disclosed in the present invention is a seabed type static cone penetration apparatus, comprising a base, a penetration rod power unit, and a casing power unit. The penetration rod power unit comprises four extrusion wheels, a displacement power structure, and a rotating power structure; and the casing power unit comprises a clamping power structure and a raising/lowering power structure. The penetration rod power unit clamps a penetration rod and enables the penetration rod to penetrate downwards, and the casing power unit clamps a casing and enables the casing to penetrate downwards. According to the present invention, by combining the mode of casing penetration by hydraulic cylinders and the mode of penetration of a penetration rod by extrusion wheels, the function of lowering not only a penetration rod but also a casing can be realized by one apparatus, the penetration force after the two penetration modes are combined is greater than the penetration force of penetration by only the hydraulic cylinders or only the extrusion wheels, thereby solving the problem that the penetration rod cannot be lowered after the casing is lowered due to insufficient penetration force of seabed type static cone penetration apparatuses, and the seabed type static cone penetration apparatus is suitable for deep water areas and severe construction environments.
