Description
技术领域technical field
本发明属于电力施工领域,涉及一种电线杆的架设施工方法,特别是一种水泥电线杆防倾倒的架设施工方法。The invention belongs to the field of electric power construction, and relates to a construction method for erecting a utility pole, in particular to a construction method for erecting a cement utility pole against dumping.
背景技术Background technique
在电力维护过程中,经常会遇到由于风雨天气等原因导致的电线杆倾斜的现象。电线杆一旦倾斜,就很容易对输电线路造成拉扯,严重时会将输电线路拉断,造成大面积的停电。In the process of power maintenance, it is often encountered that the utility pole is tilted due to wind, rain, weather and other reasons. Once the utility pole is tilted, it is easy to cause a pull on the transmission line, and in severe cases, the transmission line will be broken, causing a large-scale power outage.
对于水泥电线杆在盐碱地地区的架设工作,除了要考虑天气的因素,还要考虑地质的因素。在具体的实践中,虽然电线杆的底部采用高抗硫酸盐水泥浇筑,但是依然出现了密集的纵向裂缝。水泥电线杆在盐碱地架设的稳定性问题得不到解决,输电线路的长期安全运行就得不到保障,因此,发明一种具有稳固性强、延长电杆的使用寿命、防倾倒的水泥电线杆在盐碱地地区的架设施工方法是十分有必要的。For the erection of cement poles in saline-alkali areas, in addition to weather factors, geological factors must also be considered. In practice, although the bottom of the utility pole is poured with high sulfate-resistant cement, dense longitudinal cracks still appear. If the stability problem of cement utility poles erected in saline-alkali land cannot be solved, the long-term safe operation of transmission lines cannot be guaranteed. Therefore, a cement utility pole with strong stability, prolonging the service life of the utility pole, and anti-dumping is invented. It is very necessary to erect construction methods in saline-alkali areas.
