Pile sinking construction method utilizing shipborne telescopic pile holding arm moving guide frame
The invention provides a pile sinking construction method utilizing a shipborne telescopic pile holding arm moving guide frame. The pile sinking construction method comprises the steps that (1) pile sinking positioning is conducted, specifically, a coarse positioning system for pile sinking is combined with an accurate positioning system for pile sinking; (2) steel pipe pile self-sinking construction is conducted; and (3) steel pipe pile vibration sinking construction is conducted through a vibration hammer. According to the pile sinking construction method, the technical requirement that under the high tidal range environment, the telescopic pile holding arm moving guide frame is used for hoisting and beating a steel pipe pile, and the steel pipe pile with poor self-stability can be constructed under limiting of the guide frame through the vibration hammer and an impact hammer is met, a high-precision scanner and a GPS pile sinking independent positioning system are used, the system can achieve real-time monitoring of the perpendicularity and the plane position of the steel pipe pile in the whole pile sinking process, investment of auxiliary measuring personnel and measuring equipment is reduced, investment of ship machine equipment can be saved, and the pile sinking precision is improved.
一种利用船载式可伸缩抱桩臂移动导向架的沉桩施工方法，其步骤为：(1)沉桩定位：沉桩的粗定位系统结合沉桩的精确定位系统：(2)钢管桩自沉施工；(3)振动锤振沉钢管桩施工；本发明解决了在大潮差环境下，使用可伸缩抱桩臂移动导向架进行钢管桩吊打可实现对自稳性较差钢管桩使用振动锤及冲击锤在导向架限位下施工的技术要求，使用高精度扫描仪+GPS沉桩独立定位系统，该系统可实现沉桩全过程钢管桩垂直度及平面位置的实时监测，减少了辅助测量人员及测量设备的投入、可节省船机设备的投入，提高沉桩精度。
