UPVC井管在云南抗旱供水井中的应用

Application of UPVC Well Pipe for Drought Relief in Yunnan

在水井工程中,国外现在应用较多的是UPVC全塑料井管,而在我国却不然。分析了UPVC全塑料井管在水井应用中的优缺点,并通过其在云贵高原的应用实例,介绍了UPVC全塑井管在下井管、止水、洗井工艺中的关键技术。实际应用表明,UPVC井管可以保证成井质量,提高施工技术,UPVC全塑井管在农村及干旱地区的应用前景巨大,有很好的推广价值。

In the well project,UPVC all plastic well pipe is more applicated overseas,but it is not the case in China.This paper describes the advantages and disadvantages of UPVC all plastic well pipe in the well application;introduces the key technologies of the well-pipe putting,water sealing and well flushing process by the application cases in Yunnan-Guizhou plateau.Actual practice shows that UPVC well pipe can guarantee the well completion quality and improve the construction technology,which has very good promotion value in China,especially in rural and arid areas.
