Deviation rectifying method for pile top levelness of offshore wind turbine foundation single pile
The invention discloses a deviation rectifying method for the pile top levelness of an offshore wind turbine foundation single pile, which comprises the following steps: step 1, carrying out levelness scanning on the top surface of a pile top flange of the single pile on site, finding out the highest point and the lowest point of the pile top flange, and obtaining the maximum height difference value of the top surface of the pile top flange; step 2, calculating the top face levelness of the pile top flange according to the maximum height difference value of the top face of the pile top flange and the pile diameter of the single pile; step 3, drawing a correction scheme schematic diagram of the bottom section tower drum of the fan; step 4, drawing a corrected cutting machining drawing for the machined bottom section tower drum in a tower drum manufacturing plant; step 5, cutting the bottom section tower drum and the drum bottom flange open, then correcting and cutting the bottom section tower drum according to the correction cutting machining drawing, and then connecting the drum bottom flange and the bottom section tower drum in a welded mode again; and step 6, transporting the bottom section tower barrel with the barrel bottom flange welded again to the site, and then connecting the barrel bottom flange with the pile top flange of the single pile. The deviation rectifying method is high in deviation rectifying speed and low in cost.
本发明公开了一种海上风机基础单桩的桩顶水平度的纠偏方法，包括：步骤一，现场对单桩的桩顶法兰的顶面进行水平度扫测，找出桩顶法兰的最高点和最低点，得到桩顶法兰顶面的最大高差值；步骤二，根据桩顶法兰顶面的最大高差值和单桩的桩径计算桩顶法兰的顶面水平度；步骤三，绘制风机的底节塔筒的修正方案示意图；步骤四，在塔筒制造厂内对已加工完成的底节塔筒绘制修正切割加工图；步骤五，先将底节塔筒与筒底法兰切开，再按修正切割加工图对底节塔筒修正切割，然后重新将筒底法兰与底节塔筒焊接连接；步骤六，将已经重新焊接好筒底法兰的底节塔筒运到现场，再将筒底法兰与单桩的桩顶法兰连接。本发明的纠偏方法不仅纠偏速度快，而且成本低。
