Airbag-assisted underwater sinking pipe rotary sinking construction method
The invention discloses an airbag-assisted underwater sinking pipe rotary sinking construction method, which comprises the following steps of: 1, configuring a plurality of first airbags on one side above a target posture of sinking construction along a pipeline on the water surface, and configuring a plurality of second airbags on one side below the target posture of sinking construction along the pipeline; secondly, the pipeline with the air bags is moved to the preset position of the water surface of the top of the foundation trench in place, and first lifting equipment on the two banks and a plurality of second lifting equipment on the water surface are connected; 3, the pipeline is filled with water; fourthly, all the second air bags are dismantled; 5, the first air bags are deflated synchronously, and deflation is stopped when the lifting force of the second lifting equipment exceeds the first set value; sixthly, lifting points of the second lifting equipment are synchronously and gradually lowered, and the pipeline is turned over by 90 degrees; and seventhly, lifting points of the first lifting equipment and the second lifting equipment are synchronously and gradually loosened, so that the pipeline sinks into the foundation trench. The air bag is adopted for floating, mounting and dismounting are easy, and use is flexible.
本发明公开了一种气囊辅助水下沉管旋转沉放施工方法，包括：步骤一：在水面沿管道下沉施工目标姿态的上方一侧配置若干第一气囊，并沿管道下沉施工目标姿态的下方一侧配置若干第二气囊；步骤二：将配置好气囊的管道移动至基槽顶部水面处预定位置就位，并连接两岸的第一起吊设备和水面上的若干第二起吊设备；步骤三：向管道内灌满水；步骤四：拆除所有的第二气囊；步骤五：对各个第一气囊同步进行放气，使各个第二起吊设备的吊力均超过第一设定值时停止放气；步骤六：同步的逐渐下放各个第二起吊设备吊点，使管道翻转90°；步骤七：同步的逐渐松开第一起吊设备和第二起吊设备吊点，使管道下沉至基槽内。采用气囊进行配浮，安装拆卸容易，使用灵活。
