The invention provides a deepwater suction anchor and a using method thereof, and belongs to the technical field of ocean engineering equipment, the deepwater suction anchor comprises a main anchor cylinder and an auxiliary anchor cylinder, the main anchor cylinder is a hollow cylinder with an opening in the bottom end, and a drainage hole used for being connected with external negative pressure equipment is formed in the top of the main anchor cylinder; the auxiliary anchor cylinder is a hollow cylinder with two open ends, the auxiliary anchor cylinder is fixedly connected to the peripheral wall of the main anchor cylinder through a connecting plate, and the axis of the main anchor cylinder and the axis of the auxiliary anchor cylinder are located on the plane where the connecting plate is located. According to the suction anchor for deepwater, the lateral friction force between the suction anchor and a soft soil layer can be effectively improved on the premise that disturbance to a soil body is reduced, and the vertical bearing capacity and the horizontal bearing capacity of the suction anchor under various working conditions can be improved.

    本发明提供了一种深水用吸力锚及其使用方法,属于海洋工程设备技术领域,其中,深水用吸力锚包括主锚筒和辅助锚筒,主锚筒为底端开口的中空圆柱体,所述主锚筒的顶部设置有用于与外部负压设备连接的排水孔;辅助锚筒为两端开口的中空圆柱体,所述辅助锚筒经由连接板固定连接于所述主锚筒的外周壁上,所述主锚筒的轴线和所述辅助锚筒的轴线位于所述连接板所在平面上。本发明提供的深水用吸力锚,能够在减少对土体扰动的前提下有效提升吸力锚与软土层之间的侧向摩擦力,并可提升各种工况下的吸力锚的竖向承载力和水平承载力。
