The Key Technology On Transportation And Lifting Of U-Shaped Beam Of Jinan Railway Line R1
2016 INTERNATIONAL CONFERENCE ON SMART CITY AND SYSTEMS ENGINEERING (ICSCSE)(2016)
摘要
U-Shaped beam is an open thin-walled section with low tensional rigidity, high installation precision and high construction difficulty. Under the construction requirements of the U-shaped beam of Jinan railway Line R1, the researcher designs a special lifting machine, selects a reasonable transport vehicle, and the hydraulic balance system of road transportation is designed at the same time to reduce the torsion and ensure the construction quality of the U-shaped beam structure. Good results have been achieved.
