[Abstract]:Reverse lining technology is a new technology in domestic gas industry in recent years. Its principle is to flip tubular polyurethane film fabric onto the inner wall of clean old pipe through high strength adhesive and compressed air. After normal temperature pressure solidification, the inner wall of the old pipe is sealed completely, so as to repair the old pipe. Beijing gas industry introduced the medium-pressure flip lining technology more than ten years ago and made some achievements. With the rapid development of urban construction, the original medium-pressure lining technology can not meet the requirements of urban gas pipeline repair. Therefore, in 2011, the introduction of high-voltage technology as a perfect supplement. The cleaning process of pipeline is an important link to the success of reverse lining construction. The purpose of this paper is to find out the optimal cleaning scheme through the study of pipeline cleaning methods, compare the similarities and differences of several ways, and provide the theoretical basis for the reverse lining repair technology in Beijing gas industry and even in the national gas industry in the future. Based on the research of actual engineering, it is found that the cleaning process of pipeline is independent, but it is also complementary to each other. The reasonable use in the project can make the project be completed better, and the quality will be guaranteed more.
