Clamp type transformation method for improving icing torsional rigidity of old line iron tower
The invention discloses a clamp type transformation method for improving the icing torsional rigidity of an old line iron tower. The transformation method comprises the following steps: step 1, calculating an electrical load effect of an iron tower under a non-uniform icing working condition combination; step 2, according to the electrical load effect, calculating the part, wherein the torsional rigidity of the tower body of the iron tower does not meet the non-uniform icing torsional bearing capacity requirement, of the tower body; and step 3, aiming at the part of the tower body of the iron tower, of which the torsional rigidity does not meet the non-uniform icing torsional bearing capacity requirement, carrying out reinforcement and transformation by utilizing a transformation device. On the basis that the original tower is not completely dismantled or replaced or a new iron tower is not erected, local reinforcement transformation is carried out on the icing position, insufficient in torsional rigidity, of the tower body of the old line iron tower, the investment cost can be saved, the power failure time can be shortened, and the overall anti-icing bearing capacity of the iron tower can be effectively improved; and meanwhile, clamp type bolt connection is adopted, the construction operation difficulty and workload of high-altitude welding and bolt drilling can be effectively reduced, and the beneficial effects of being easy and convenient to install and high in feasibility are achieved.
本发明公开了一种夹具式老旧线路铁塔提高覆冰扭转刚度改造办法，包括：步骤1、计算出铁塔不均匀覆冰工况组合下的电气荷载效应；步骤2、根据电气荷载效应，计算得出铁塔塔身抗扭刚度不满足不均匀覆冰受扭承载能力要求的部位；步骤3、针对铁塔塔身抗扭刚度不满足不均匀覆冰受扭承载能力要求的部位，利用改造装置进行加固改造。本发明在不进行原塔全部拆除更换或者新立铁塔的基础上，对老旧线路铁塔塔身覆冰抗扭刚度不足位置进行局部补强改造，既能够节约投资造价、减少停电时间，又能有效提高铁塔整体防冰承载能力；同时本发明采用夹具式螺栓连接，能够有效降低高空焊接、螺栓钻孔的施工作业难度及工作量，具备安装简便，可实施性强的特点。
