Barrel-shaped foundation structure for ocean engineering and mounting method
The invention relates to a barrel-shaped foundation structure for ocean engineering and a mounting method, and belongs to the technical field of ocean geotechnical engineering. A system comprises a barrel-shaped foundation model which comprises a steel barrel, a piston cylinder gasket in contact with the inner wall of the steel barrel is arranged in the steel barrel, a piston shaft for driving thepiston cylinder gasket to move up and down is connected to the piston cylinder gasket, a through hole with the diameter larger than that of the piston shaft is formed in the top face of the steel barrel, and the top surface of the steel barrel is also connected with a steel support; and a penetrating hole which is coaxial with the through hole and allows the piston shaft to move up and down inside the penetrating hole is formed in the steel support, and the inner diameter of the penetrating hole is equal to the diameter of the through hole. According to the barrel-shaped foundation structure,a gap between the piston shaft and the inner wall of the penetrating hole of the steel supporting structure can be used, air suction and inflation can be carried out in the steel barrel, a barrel-shaped foundation can be embedded into a seabed through the pressure difference between the interior and the exterior of the steel barrel, in this way, excessive uneven stress cannot be generated on a soil body, and fixing can be rapidly relieved.
本公开涉及一种用于海洋工程的桶形基础结构及安装方法，属于海洋岩土工程技术领域，该系统包括桶型基础模型，所述桶型基础模型包括钢桶；钢桶内设有与钢桶内壁相接触的活塞缸垫；在活塞缸垫上连接有驱动活塞缸垫做上下运动的活塞轴；在钢桶的顶面设有直径大于活塞轴直径通孔；所述钢桶顶面还连接有钢支撑；钢支撑内设有与所述通孔同轴线、且活塞轴可在内部上下运动的贯通孔；贯通孔的内径与通孔直径相同。本公开的桶形基础结构可利用活塞轴与钢支撑结构的贯通孔内壁之间的间隙钢桶内进行吸气和充气，利用钢桶内外的压力差可实现将桶形基础嵌入海床中，这样对土体不会产生过大的不均匀受力，且可快速解除固定。
