| 泵送C50高性能混凝土在客運(yùn)專線900 t箱梁施工過程中的質(zhì)量控制(49 卷) |
| 英文標(biāo)題 |
| Quality control over pumped C50 high-performance concrete during construction of 900-t box |
| 摘要 |
| 石太鐵路客運(yùn)專線冶河特大橋工程的墩身平均高度36 m以上，箱梁制作擬采用移動(dòng)模架原位現(xiàn)澆C50高性能混凝土的施工工藝，混凝土垂直運(yùn)輸采用 48 m泵車進(jìn)行。通過采用一系列技術(shù)措施，冶河特大橋工程成功地完成全部箱梁混凝土運(yùn)輸和澆筑工作，施工質(zhì)量控制優(yōu)良。 |
