摘要
在高速公路桥梁施工过程中,预制小箱梁保护层控制是施工中的重难点,结合静庄高速公路项目预应力简支小箱梁钢筋骨架纵向分布筋的张拉技术进行探讨,总结经验、采取技术措施保证预制小箱梁的施工质量,顺应现代公路施工发展方向。
Combination in the process of the highway bridge construction,small precast box girder protective layer control is a difficult point in construction,combined with the tensioning technology for the longitudinally distributed bar in reinforcement cage of the prestressed simple supported small box girder in Jiangzhuang highway project,paper sums up experience,take technical measures to ensure the quality of small precast box girder construction,adapt to the modern highway construction development direction.
