在用翻模施工方法的烟囱施工中,中央竖井架需拉设多道缆风绳。缆绳的拉设影响烟囱周围建筑物,尤其对主厂房的施工造成很大影响。龙口电厂的主厂房框架开始吊装施工时,烟囱筒身最高只能施工到120m,150m处的缆绳无法避开塔吊行走区,所以缆绳是否妨碍塔吊行走必须在搭设竖井架之前准确地确定。为此,必须解算缆绳的曲线方程。现以龙口电厂
In the construction of the chimney with the turn-up construction method, the central vertical derrick needs to be equipped with multiple cable wind ropes. The laying of ropes affects the buildings around the chimneys, especially the construction of the main building. When the main plant frame of Longkou Power Plant began to be hoisted, the chimney can only be constructed to a height of 120m. The cables at 150m cannot avoid the tower crane’s walking area. Therefore, whether or not the cable interferes with the tower crane must be accurately determined before erecting the vertical mast. For this reason, the curve equation of the cable must be solved.
