The invention discloses a pile sinking construction method for a fixed arm type frame crane ship. The pile sinking construction method comprises the following steps that S1, the crane ship travels to be close to a construction machine position, and anchoring and positioning are conducted; S2, a guide pipe frame transport ship correspondingly loaded with a guide pipe frame and a single pile transport ship travel to be close to the construction machine position, anchoring and positioning are conducted to be parallel, and the guide pipe frame transport ship, the single pile transport ship and the crane ship are arranged in a T shape; S3, the guide pipe frame is hoisted to the position below the mud face of the construction machine position through the crane ship to be fixed; and S4, the single pile is hoisted to the guide pipe frame through the crane ship, and pile inserting and pile sinking construction are conducted. The fixed arm frame type crane ship is adopted as construction hoisting equipment, an existing common hoisting ship is fully utilized, and the input cost is saved; anchor point coordinates of the crane ship and the transport ships are calculated and planned according to the specific position of the construction machine position, ship positioning errors are prevented, and the construction operation efficiency is improved; the levelness of the hoisting guide pipe frame is measured in real time, the guide pipe frame is adjusted in time to keep horizontal, the vertical accuracy of subsequent pile sinking is improved, and the pile sinking operation efficiency and precision are improved; and the coordination of the overall construction process is good, the construction process is safe, and the operation efficiency is high.
本发明公开固定臂式架起重船沉桩施工方法,包括以下的步骤:S1:起重船行驶靠近施工机位,抛锚定位;S2:对应载有导管架、单桩的导管架运输船及单桩运输船行驶靠近施工机位处抛锚定位成相互平行,均和起重船形成T形排列;S3:起重船将导管架吊至施工机位泥面下固定;S4:起重船将单桩吊至导管架上插桩、沉桩施工。施工吊装设备采用固定臂架式起重船,充分利用现有常见吊装船,节约投入成本;根据施工机位具体位置计算规划好起重船和运输船的锚点坐标,防止船舶定位错误,提高施工作业效率;吊装导管架实时测量水平度,及时调整保持水平,提高后续沉桩的垂直准确度,提高沉桩作业效率及精度;整体施工过程协调性好,施工过程安全,作业效率高。
