Application of Non-excavation Pipeline Repair Technology in Urban Water Supply Expansion——Case study based on"U"shaped PE pipe folding inner lining technology
Based on the application advantages of non-excavation pipeline repair technology,combined with an example of upgrading and renovating a city's water supply pipeline,this paper discusses the application advantages,basic principles,and construction process of the"U"shaped PE pipe folding inner lining repair technology,analyzes the key points of the"U"shaped PE pipe folding inner lining repair construction technology,and evaluates the application advantages of this technology in the upgrading and renovating of urban water supply pipelines.Engineering practice has shown that the U-shaped PE pipe folding lining repair technology not only has a good effect on the renovating of old urban water supply pipes which can effectively improve water quality,reduce pipeline water resistance,but also has a small impact on the environment and traffic along the line with significant comprehensive benefits.
