The invention relates to a pier falling method used after a half ship floats, which is used for falling a pier again after the half ship floats in a dock, winches are respectively arranged at the bow part, the midship part and the stern part of the half ship, the winches are connected with mooring ropes, one ends of the mooring ropes are connected with the winches, and the other ends of the mooring ropes are connected to a fixing structure beside the half ship; marking a center line along the bow and stern directions of the half ship, respectively pasting positioning marks at the bow and stern ends of the half ship along the center line, and measuring the positions of the positioning marks before floating through a total station; after the half ship floats, the pier falls again, the position of the positioning mark is measured through the total station, the position of the half ship is adjusted by pulling the mooring rope through the winch, and pier falling is completed after the half ship floats. By means of the method, the position of the pier falling again after the half ship in the dock floats is adjusted, the problem that the position changes after the half ship floats is solved, the precision after pier falling again meets the construction precision requirement, and the cost and working hours for producing stand column tool pieces are saved.

    本发明涉及一种用于半船起浮后的落墩方法,用以船坞内半船起浮后再次落墩,在半船的艏部、舯部、艉部分别设置绞盘机,绞盘机连接缆绳,缆绳的一端连接绞盘机,缆绳的另外一端连接到半船旁边的固定结构上;沿半船的艏艉方向划制中心线,沿中心线在半船的艏艉两端分别张贴定位标记,通过全站仪测量定位标记起浮前的位置;待半船起浮后再次落墩时,通过全站仪测量定位标记的位置,通过绞盘机拉动缆绳对半船的位置进行调整,完成半船起浮后落墩。通过本发明的方法对坞内半船起浮后再次落墩的位置进行调整,解决了半船起浮后位置变化的问题,再次落墩后的精度满足建造精度要求,且省去了生产立柱工装件的成本和工时。
