Overwater positioning method for pressure-bearing buoy of floating bridge
The invention discloses an overwater positioning method for a pressure-bearing buoy of a floating bridge. The overwater positioning method comprises the steps that firstly, a base platform and berthing piers are erected; secondly, the pontoon is dragged to the position close to the base platform through tugs; thirdly, initial positioning of the buoy is completed through four platform winches on the base platform and berthing pier winches on berthing piers; 4, ballast water is injected into the buoy, so that the buoy sinks; 5, the floating cylinder is located on the base platform; sixthly, a pair of longitudinal jacks and two pairs of transverse jacks on the base platform are started, and the plane position of the buoy is finely adjusted; and 7, after a pier body heightening procedure and a pier body and main beam connecting procedure are sequentially carried out on the buoys, ballast water in the buoys is pumped out through a water pump to enable the buoys to float upwards, and then the buoys, the pier body on the buoys and the main beam are dragged away from the working area of the base platform through tugs. The stability of the buoy in water can be ensured, and subsequent butt joint of the buoy and the pier body and butt joint of the pier body and the main beam are facilitated.
本发明公开了一种浮桥承压浮筒的水上定位方法，包括：步骤一，搭设座底平台和靠泊墩；步骤二，利用拖轮将浮筒拖行至座底平台附近；步骤三，通过座底平台上的四个平台卷扬机和靠泊墩上的靠泊墩卷扬机，完成浮筒的初定位；步骤四，向浮筒内注入压载水，使浮筒下沉；步骤五，将浮筒坐落在座底平台上；步骤六，启动座底平台上的一对纵向千斤顶和两对横向千斤顶，进行浮筒的平面位置的精调；步骤七，在浮筒上依次进行墩身接高工序以及墩身与主梁连接工序后，先利用水泵抽出浮筒内的压载水，使浮筒上浮，再利用拖轮将浮筒连同浮筒上的墩身和主梁一起拖离座底平台的工作区域。本发明能确保浮筒在水中的稳定性，便于后续浮筒与墩身以及墩身与主梁对接。
