Design And Application Of UHV Tubular Tower Erection And Assembly By Inside Suspension Pole With Outside Guyed Wires

In the process of steel pipe tower component lifting, detailed design and force checking have been done to ensure safety of erection and assembly tower and entire erection and assembly tower scene has been successfully completed at last. It has once again verified the feasibility of pipe tower assembly and erection by inside suspension pole with outside guyed wires and accumulated more experience of erection and assembly tower in uhv transmission in the future.With power load fast-growing increasingly, and increasing demand for bulk transmission overlong distance, large-scale uhv transmission lines construction is becoming crucial. In accordance with the State Grid plan, five horizontal and five longitudinal uhv ac transmission lines will be built in 2020. Uhv transmission lines towers, particularly double-line pipe towers, are much high and heavy, essential differences from angle iron towers. It faces many safety risks to erect and assemble tower by traditional inside suspension pole with outside guyed wires.In order to solve the problem of uhv steel pipe tower erection and assembly, This article has mainly researched on the design and practical application of uhv pipe tower assembly and erection by inside suspension pole with outside guyed wires. The force of embraced bar identity and the entire lifting system has been numerical. The appropriate specification equipment has been selection. Entire erection and assembly tower scene and construction process has been designed. The safety and convenience of tower assembly and erection have been rised again by setting a series of safty lifting devices.
