水泥蓋板使用時注意事項

2020-05-26 14:38:04

1、由于密度小,材質輕,在地下水位較高地區水泥蓋板易浮管,必需考慮設置鎮墩或雨水徑流疏導等抗浮措施。  

2、在已裝水泥蓋板上開三通、修補管道裂縫等施工中,要求類似與廠房內的完全干燥條件且施工時使用的樹脂及纖維布還需7—8小時固化,而現場施工與補修一般很難達到此要求。 

3、現有地下管線探測設備主要以探測金屬管線為主,而非金屬管道探測儀器價格昂貴,因此水泥蓋板埋地后無法探測,其它后續施工單位在施工中挖傷、損壞管道。?  

4、水泥蓋板防紫外線能力差。明裝水泥蓋板通過在其表面制作0.5mm厚的富樹脂層和紫外線吸收劑(廠內加工),來延緩老化時間。隨著運行時間的推移,富樹脂層和紫外線吸收劑會遭到破壞,從而影響其使用壽命。
