The invention relates to a suction anchor which comprises a barrel, the top of the barrel is sealed through a top plate, the bottom of the barrel is open, the barrel comprises a first section, a second section and a connecting section, the first section is arranged above the second section and is concentric with the second section, and the diameter of the first section is larger than that of the second section; the top end of the second section is lower than the bottom end of the first section, and the second section and the first section are connected through an obliquely-arranged connecting section. And the drain valve is arranged on the top plate and used for being connected with a suction pump so as to drain seawater in the cylinder body to enable the suction anchor to sink under negative pressure. The top of the barrel is sealed through the top plate, the bottom of the barrel is open, the top plate is provided with the drainage valve used for being connected with the suction pump, and seawater in the barrel is discharged by the suction pump during injection so that the suction anchor can sink under negative pressure; and in the penetration process of the suction anchor, the soil body in the cylinder ascends slowly after the cross sectional area is increased, so that the soil plug effect is weakened, and the height difference of the soil bodies inside and outside the cylinder is reduced after final sinking is finished.

    本公开涉及一种吸力锚,包括:筒体,其顶部通过顶板密封,底部开口,筒体包括第一段、第二段和连接段,第一段设置在第二段的上方且与第二段同心设置,第一段的直径大于第二段的直径,第二段的顶端低于第一段的底端且二者之间通过倾斜设置的连接段连接;以及排水阀,设置在顶板上用于与吸力泵连接以排出筒体内的海水使吸力锚负压下沉。本公开筒体的顶部通过顶板密封,底部开口,顶板上设有用于连接吸力泵的排水阀,在贯入时吸力泵排出筒体内的海水使吸力锚负压下沉,筒体的第一段的直径大于第二段的直径,在吸力锚贯入过程中使得筒体内土体在横截面积增大后上升缓慢,从而减弱了土塞效应,使得最后下沉结束后筒体内外土体高度差减小。
