研究电杆裂缝的成因及其避免裂缝产生,对于提高水泥电杆的使用寿命,提高线路的安全运行水平,有着十分重要的意义.也是当前电网建设中一个亟待解决的重大课题.本文就普通钢筋混凝土电杆产生的纵向裂缝问题,进行再认识.一、纵向裂缝的表现形式及其规律根据全国各地水泥电杆裂缝的调查,纵裂表现如下的形式及规律:1纵向裂缝主要产生在电杆地面至地面上2米的范围内.
Studying the causes of cracks in electric poles and avoiding the generation of cracks is of great significance for improving the service life of cement poles and improving the level of safe operation of the lines. It is also a major issue to be solved in the current grid construction. Longitudinal cracks produced by concrete poles are reconsidered. First, longitudinal cracks manifestations and their laws According to the investigation of cracks in cement poles across the country, the longitudinal cracks show the following forms and patterns: 1 Longitudinal cracks are mainly generated in poles. Ground to the ground within 2 meters.
