Abstract:The erection of natural gas transportation pipeline aerial crossing tower is often difficult due to the site conditions. In this regard, introduced are the relevant conditions of the comparison and selection of common erection ways according to the site actual condition of Han-Jiang Aerial Crossing, Lifting and Pushing Method is brought out for the erection. Combined with the characteristic of the erection of natural gas transportation pipeline aerial crossing tower, described are operating principles of Lifting and Pushing Method which is used in Han-Jiang aerial crossing tower erection and the ultimate load condition. in addition, the main calculations and innovation in this project are introduced. Han-Jiang Aerial Crossing tower erection experience shows that Lifting and Pushing Method has the characteristics such as high adaptability for sites, safety and economy etc, which is a worthily spreading method in natural gas transportation pipeline aerial crossing project.
