Design and construction for support system of high-altitude and long-span gallery structure

Facing the difficulty for support system construction of high-altitude and long-span gallery structure in practical engineering,the paper analyzed the drawbacks of conventional steel tubular scaffold and determined preliminary scheme which using steel lattice truss.To optimize the design,steel tubular scaffold support systems of different section and style were detailed compared,the final scheme was chosen on the basis of advantages and disadvantages analyzing.Otherwise,vulnerability to problems in construction segments and corresponding construction measures were discussed in accordance with its construction process,for these measures,quality and safety were ensured,and achieved obvious comprehensive benefit.
