Abstract
Provided is a combined suction anchor reinforced by a grouting spiral anchor, including a gravity suction anchor, an L-shaped skirt board and a spiral anchor. The gravity suction anchor includes a suction anchor top plate and a wall of a suction anchor barrel body and uses a concrete press block to reach an estimated set position faster during penetration due to self-weight thereof. Thereafter, the skirt board is lifted to outside of the suction anchor through a lug, and a fixing bolt is used to connect the skirt board to the suction anchor. The spiral anchor rod passes through a skirt board hole performed in the skirt board to penetrate into a deep site of seabed, and concrete is grouted through the skirt board hole to a seabed soil area loosened due to penetration of the spiral anchor rod, thereby forming a concrete reinforced area after the concrete solidifies.
