The invention discloses a bag type grouting anchoring foundation for a mooring net cage and a construction method. The bag type grouting anchoring foundation comprises a reinforcement cage, a bag, ananchor chain and a grouting pipe, wherein an anchor head is fixedly connected to the bottom end of the reinforcement cage, a reinforcing ring is fixedly connected to the middle of the reinforcement cage, and a mooring ring is fixedly connected to one side of the reinforcing ring; a bag opening of the bag is fixed to the periphery of the upper end of the anchor head and is closed, the bag sleeves the periphery of the reinforcement cage and covers the upper end face, the inner wall and the outer wall of the reinforcement cage and the upper end face of the anchor head, and a preformed hole is formed in one side of the bag; the grouting pipe is fixed to one side of the anchor chain, the anchor chain and the grouting pipe penetrate through the preformed hole from outside to inside and extend into the bag, the anchor chain is moored on the mooring ring, a grout outlet of the grouting pipe is located in the bottom of the reinforcement cage, and grout is injected into the bag. The bag is filled with the grout, and the reinforcement cage is wrapped by the grout, which is equivalent to a cast-in-place reinforced concrete structure, so that the integrity is high, the uplift bearing capacity is large, the construction is simple and convenient, the offshore operation time is short, and the comprehensive cost is low.
本发明公开了一种用于系泊网箱的囊式注浆锚泊基础及其施工方法,包括有钢筋笼、囊袋、锚链和注浆管,钢筋笼的底端固定连接有锚头,钢筋笼的中部固定连接有加强环,加强环的一侧固定连接有系泊环;囊袋的袋口固定在锚头上端的四周并呈封闭状,囊袋套在钢筋笼的四周并覆盖钢筋笼的上端面和内、外壁以及锚头的上端面,囊袋的一侧设有预留孔;注浆管固定在锚链的一侧,锚链和注浆管自外而内穿越预留孔并延伸到囊袋的内部,锚链系泊在系泊环上,注浆管的出浆口位于钢筋笼的底部,囊袋内注入有浆液。本发明将浆液填充在囊袋内部并包裹钢筋笼,相当于现浇钢筋混凝土结构,整体性强,抗拔承载力较大,施工简便,海上作业时间短,综合成本低。
