Abstract
A complete unit for high altitude construction in winter aims to solve the problem that the construction period in severe cold district in north china is short, the winter covers six months, and the temperature in winter is below minus 30 DEG C, however, a cable-stayed bridge main tower body requires long construction period. By adopting the high tower body winter-construction complete techniques, cross-year construction of the tower body is avoided. The complete unit comprises a strength steel skeleton (1), the strength steel skeleton is wrapped and connected with a movable greenhouse wall (2), a greenhouse roof (3) is arranged above the movable greenhouse wall, a hot air curtain (4) is mounted below the greenhouse roof, a hydraulic automatic creeping formwork device (5) is connected to the lower part of the movable greenhouse wall, and a group of steam pipes (6) and a group of warm water pipes (7) are mounted in the movable greenhouse wall (2). The complete unit is suitable for the bridge construction in severe cold district in north China in winter.
