Abstract:The erection of natural gas pipeline aerial crossing tower is often difficult due to the restricted site conditions. Introduced are actual conditions at the site of Hanjiang aerial crossing tower erection, compared are common erection ways and selected is the lifting and pushing method for Hanjiang gas pipeline aerial crossing tower erection. In combination with the characteristics of gas pipeline aerial crossing tower erection, described are the operating principle of the lifting and pushing method in Hanjiang gas pipeline aerial crossing tower erection and adverse working conditions and introduced are main calculations and innovation in this project. Practical experience in this project shows that the lifting and pushing method has such advantages as strong site adaptability, safety and less investment and this method may be applied widely in gas pipeline aerial crossing projects.
