摘要
文章结合杭宁高速(浙江段)改扩建工程II标两座变截面钢箱梁桥面UHPC铺装施工,阐述了铺装层超高性能混凝土在原材料、配合比与检验、拌合与运输、摊铺浇筑、养护等施工关键环节的质量控制措施,并针对特殊天气环境下的施工给出了应对措施,实现本工程高质量的顺利完成,也为同类工程施工提供借鉴与参考。
Based on the UHPC pavement construction of two variable-section steel box girder bridge decks in the reconstruction and expansion project of Hangzhou-Nanjing Expressway(Zhejiang Section), the paper expounds the raw materials and mix proportion of the pavement layer ultra-high performance concrete, and puts forward quality control measures for the key construction links such as inspection, mixing and transportation,paving and pouring, and maintenance. The article also gives countermeasures for the construction under special weather conditions to achieve the smooth completion of the project with high quality. This provides a reference for the construction of similar projects.
