Second-generation in-situ test device for strength of shallow water sediment

摘要

The invention discloses a second generation beach shallow sea sediment strength in-situ detection device, which comprises an operation ship and a static sounding unit carried on the operation ship, wherein the static sounding unit comprises an installation frame, a penetration unit, a control cabin and a hydraulic unit, the penetration unit and the hydraulic unit are electrically connected with the control cabin, according to the invention, the detection device is carried on the operation ship, the static sounding unit is carried on the operation ship with a specific structure, the device is laid and recycled by a ship body central moon pool based on a double-cable hoisting frame, the efficiency and safety of sediment strength detection operation under the beach shallow sea environment areobviously improved, the connection and disassembly of partial sounding rods are completed on a moon pool cover plate, the sounding depth can reach to 20 meters; the design of a stroke magnifying mechanism of a combination of a hydraulic cylinder driving a pulley is used to control the rise and fall of the sounding rod, the overall height of the device is reduce, the stability of the device on theseabed is improved, the quality and precision of engineering investigation are effectively improved, and obvious economic benefits can be made, the period of marine engineering geological evaluationand survey is greatly shortened.
