外线安装电工安全作业技术 | 2012-4-10 8:35:00
1. 挖坑时安全注意事项:
①挖坑首先查明施工地点有无地下管道、电缆等地下设施,并与有关单位联系,采取安全防护措施,妥善解决。
②在居民区、交通道路附近和靠近建筑物挖坑时,应设遮栏,夜间应设虹灯标志。
③挖坑深度超过
④在松软土地挖坑时,应加挡板、撑木等防止塌方。
2.立杆与撤杆注直事项:
①必须设专人统一指挥,严格遵守电业安装规范。
②立、撤杆过程中,杆坑内不准有人工作,除指挥人员及指定人员外,其他人员必须离开距杆长1.5~2倍的距离以外。
③立杆和修整杆坑时,应有防止杆身滚动、倾斜的措施。
④立杆时,当杆塔离地
⑤撤杆时,先检查杆根并做好防止倒杆措施。挖坑前,先绑好拉绳。拆除杆上导线时,应用绳索拴牢缓慢放线,严禁直接断放线。
3.放线、撤线与紧线时,都应设专人统一指挥。工作人员不准跨在导线上或站在导线角内侧。紧、撤线前应先检查拉线、拉杆及杆根是否牢固,必要时应设临时拉线加固。
4. 在交叉跨越各种线路、道路等处放、撤线时,必须先取得有关部门的同意,采取可靠的安全措施,如搭设可靠的跨越架,在路口设专人看守等。
