PROJECT NAME
Coal Storage Workshop of Baotou City Sarachi Railway Special Line
ADDRESS
Baotou City
STRUCTURE TYPE
Steel Structure
BUILDING CATEGORY
Large-span space structural steel
HEIGHT
19 m
■ The project is a truss structure canopy, with a building area of over 90,000 square meters.
■ The truss beam is an inverted triangle structure. The maximum length of a single truss is 127.25m, the weight is 40 tons, the height of the truss is 3-4m, the width is 3.0m, and the eaves height is 19m.
■ Interval between the two transverse columns is 48.75m and 60.5m respectively. There are closed railway lines for transporting coal between the two spans. Interval between the longitudinal columns is 15m.
■ Project highlights: during the construction process, the railway system had to keep operating and the ongoing train traffics made our field construction very challenging.
■ Installation approaches: we adopted pushing up cumulative slip construction method and hydraulic synchronous slip technology. The longest slip distance is 564m, which was the longest slip distance in Asia back then.
