| Abstract: | The dispatching and communication building adopts profile steel reinforced concrete strure with large steel frame, dense steel bars and complex nodes. C60 self-compacting concrete is used for vertical members of the main building to ensure that the concrete at positions where steel bars and steel frames are dense is compacted and is free of beehive and perforation. Different measures, such as simulation test, inspection of raw materials and adjustment of mixing proportion, etc, are adopted to effectively ensure the construction quality. |
