Large-diameter concrete cylinder sinking method
The invention relates to a large-diameter concrete cylinder sinking method, which belongs to the technical field of cylinder bank protection construction, and comprises the following steps of: hoisting a large-diameter concrete cylinder to a designed position, and inserting a bottom blade foot into a soft soil foundation at the designed position under the action of self weight of the large-diameter concrete cylinder; the concrete water tank is hung on the large-diameter concrete cylinder and fixedly connected with the large-diameter concrete cylinder, and a gap between the top of the large-diameter concrete cylinder and the bottom of the concrete water tank is sealed; wherein the concrete water tank is provided with a vacuumizing bin grid and a water storage bin grid, and a suction hole is formed in the bottom of the vacuumizing bin grid; vacuumizing equipment is connected to the suction hole, water injection and drainage equipment is connected to the water storage bin lattice, air in the inner cavity of the large-diameter concrete cylinder is pumped out through the vacuumizing equipment, and meanwhile ballast water is injected into the water storage bin lattice through the water injection and drainage equipment, so that the large-diameter concrete cylinder sinks under the negative pressure effect and the gravity effect of the ballast water. The large-diameter concrete cylinder sinks through negative pressure, and construction is convenient and fast.
本发明涉及一种大直径混凝土圆筒下沉方法，属于圆筒护岸施工技术领域，其包括如下步骤：将大直径混凝土圆筒吊至设计位置，其在自重作用下使底部刃脚插入设计位置处的软土地基中；将混凝土水箱吊放至大直径混凝土圆筒上并紧固连接，密封大直径混凝土圆筒顶部与混凝土水箱底部之间的缝隙；其中，混凝土水箱设有抽真空仓格和储水仓格，抽真空仓格的底部开设有抽吸孔；将抽真空设备连接至抽吸孔，并将注排水设备连接至储水仓格，通过抽真空设备抽出大直径混凝土圆筒内部空腔内的空气，同时通过注排水设备向储水仓格内注入压载水，以使大直径混凝土圆筒在负压作用以及压载水的重力作用下下沉。本发明通过负压使大直径混凝土圆筒下沉，施工方便快捷。
