Abstract
The present invention discloses a second-generation in-situ test device for strength of a shallow water sediment, including a workboat and a static cone penetration test unit carried by the workboat, where the static cone penetration unit includes a mounting frame, a penetration unit, a control cabin and a hydraulic unit; the penetration unit and the hydraulic unit are both electrically connected to the control cabin. In this solution, the workboat is used to carry the test equipment, and the static cone penetration test unit is carried on the workboat with a special structure. Based on a double-cable lifting frame, the equipment is launched and recovered through a moon pool in the center of a hull. This significantly improves the efficiency and safety of the sediment strength test operation in a shallow water environment.
