The invention discloses a vacuum torpedo anchor capable of consolidating a soil body and a mounting method of the vacuum torpedo anchor, and belongs to the technical field of research of ocean engineering anchoring foundations. Comprising an anchor body, anchor wings, a water storage bin and a vacuum bin. An anchor body is of a double-layer steel cylinder structure with good sealing performance, and the inner layer of the anchor body is a vacuum bin; the outer layer is a water storage bin; annular and vertical grooves are formed in the outer side of the anchor body, a drainage hole is formed in the intersection point of the annular and vertical grooves, and the drainage hole penetrates through the outer wall of the anchor body to be communicated with the water storage bin. The outer side of the anchor body is wrapped with permeable gauze to prevent soil from blocking the groove; after penetration of the torpedo anchor is completed, the mooring line is tensioned, the valve on the top of the vacuum bin of the anchor body is opened, the pressure in the water storage bin is reduced, water in soil around the anchor body flows into the water storage bin in the anchor body through the groove under the action of the difference between water heads inside and outside the anchor body, the soil around the anchor body is drained and solidified, and the shear strength is improved; and the drawing bearing capacity and the stability of the torpedo anchor are greatly improved.

    本发明公开了一种可固结土体的真空鱼雷锚及其安装方法,属于海洋工程锚固基础的研究技术领域。包括锚身、锚翼、储水仓和真空仓;本发明的锚身为密封性良好的双层钢制圆筒结构,其内层为真空仓;外层为储水仓;锚身外侧设置有环向和竖向的沟槽,环向和竖向沟槽的交点处设置排水孔,排水孔贯穿锚身外壁与储水仓连通;锚身外侧包裹透水纱布,防止土体堵塞沟槽;当鱼雷锚贯入完成后,张拉系泊线,将锚身真空仓顶部阀门打开,降低储水仓内的压力,锚身周围土体内的水在锚身内外水头差的作用下,通过沟槽流入锚身内部储水仓,锚身周围的土体排水固结,抗剪强度增加,大大提高鱼雷锚拉拔承载力和稳定性。
