Problems solved by technology

[0003] At present, due to the high structural strength of the steel plate, if the plate is inserted into the mud surface, the ship will slip. Due to the high structural strength of the plate, the structure of the plate or its slideway will be deformed, and the contact part of the structure and the ship may be damaged. can cause damage to the ship, resulting in an accident

Abstract

According to the anti-scouring structure for ship bottom sitting, the anti-scouring structure is of an insertion plate type structure formed by combining a first rigid part and a second semi-rigid part, the semi-rigid part can support the weight of the rigid part and has certain rigidity, and therefore it is guaranteed that the overall structure appearance of an insertion plate does not change under the condition that no external force exists. The semi-rigid part is located below the second rigid part, if the ship sideslips, the second semi-rigid part can deform to adapt to ship sliding, and therefore the ship body cannot be damaged.

Description

technical field [0001] The application belongs to the technical field of hull protection, and in particular relates to an anti-scouring structure and method for a ship sitting on the bottom. Background technique [0002] The ship sitting on the bottom refers to: a ship that can submerge completely lands on the seabed for offshore operations, that is, the ship actively and safely runs aground. With the continuous development of marine resources and the demand for marine engineering construction, more and more ships need to have the function of sitting on the bottom. The adsorption force (including adhesion force and negative pore water pressure) between the ship sitting on the bottom (especially sitting on the bottom for a long time) and the cohesive substratum soil is the key factor affecting the ship leaving the bottom. At present, after the ship sits on the bottom, due to the action of the water flow, the water flow at the contact position between the bottom of the ship a...
