Deviation correction method for wind turbine generator foundation reinforcement
The invention discloses a correction method for wind turbine generator foundation reinforcement, which comprises the following measurement steps: selecting 6-10 measurement points on a tower drum foundation ring, placing leveling rods with a corresponding number on the measurement points, and sequentially measuring the elevation value of each measurement point and the levelness of the foundation ring by adopting a level gauge, determining the highest point and the lowest point of the foundation ring and the horizontal deviation value of the foundation ring according to the measured levelness of the foundation ring; and mounting the jack at the lowest point, namely yawing the fan blade to one side of the highest point of the foundation ring, mounting 3-5 jacks at the lowest point position, and tightly propping the output end of the jack against the flange at the root of the tower drum. According to the method, firstly, the highest point and the lowest point of the tower drum foundation ring are measured, the number of the jacks and the loads of the jacks are increased step by step for the lowest point through the jacks, so that the tower drum is safer during deviation rectification, and the deviation rectification precision is higher during wind power tower drum foundation reinforcement.
本发明公开了一种风电机组基础加固的纠偏方法，测量步骤：在塔筒基础环上选取6‑10个测量点，并将相应数量的水准尺放置于测量点上，再采用水准仪依次测量各个测量点的高程值以及基础环水平度，依据测量出的基础环水平度确定基础环的最高点和最低点，以及基础环的水平偏差值；安装最低点千斤顶步骤：将风机叶片偏航到基础环最高点一侧，并在最低点位置安装3‑5千斤顶，并将千斤顶的输出端顶紧塔筒根部上法兰。本发明首先对塔筒基础环测量出最高点和最低点，并通过千斤顶对最低点进行分步增加千斤顶的数量和分步增加千斤顶的载荷，使得在对塔筒纠偏时更加的安全，并且使得风电塔筒基础加固时纠偏的精度更高。
