Construction Technology of Steel Lattice Column by Reverse Method

Abstract:

For the construction with reverse construction method, the accurate positioning and verticality control of steel lattice column are difficult in the foundation construction. In Laopupian commercial and residential project of Wuhan, the guide frame and positioning frame of steel lattice column are designed and manufactured, the verticality and positioning adjustment are smoothly completed. By the analysis on the detected data of the excavation with reverse construction method, it is proved that both the verticality and positioning can meet the design requirements with the newly designed guide frame and positioning frame, the construction cost is effectively reduced.
