钢结构天沟下水管多烧出了一个洞,现在要补洞,有什么好的办法吗? - 工程施工 - 项目管理 - 氿上知道

满意答案
钢结构天沟的材料通常是铁板、不锈钢板,只要是这两种情况我都有办法解决,其他材料的我还没有这方面的经验,不敢乱吹。
铁板天沟:
1、将天沟洞口修成有规则的几何形状,切割一块和洞口一样大小的铁板块(通常铁板天沟为4MM,),打成坡口,调好电流大小(以不烧伤母材、不形成夹渣、气孔为准),电焊时一遍轻满打底,一遍面层,通常此时已符合要求,试水绝对符合要求;
不放心的,或焊接技术不过关的,可在上加一块大于洞口的铁板焊接,这样做到了双保险;
焊接技术可以的,还可以在天沟下烧仰焊一层;
上述烧焊完成可根据烧焊的技术能力,决定是否要打磨焊缝,以保证其外观的漂亮。
2、不锈钢天沟:
通常板厚为2MM,其操作方法和铁板基本相同,不过要注意的是焊缝的宽度、焊高,因这施工操作人员常不认真的地方;再一就是学会不锈钢的鉴别方法,因为市场上流通的大多为不锈铁,(不锈钢的纯度和价格有相当的关系),经烧焊后,其部位只要受到水的影响,易锈蚀,不任是补洞还是新做,这都要注意。
