摘要
文章结合工程实例,介绍了双索面PC斜拉桥主塔施工技术。通过主塔施工实践证明,采用真空辅助压浆工艺可解决预应力普通压浆不饱满的难题,并能通过有效的降温措施保证大体积混凝土施工质量。
Based on the construction practice,the paper introduces the construction technique for the main tower on a double plane PC cable-stayed bridge.It has been found that vacuum-assisted pouring technique is able to solve the problem of partial grouting caused by normal pre-stressed grouting technique.Also by efficient cooling measures,the construction quality of large-sized cement concrete can be guaranteed.
