真空压浆技术在凫洲大桥中的应用

The application of vacuum mud-jacking technology in Fuzhou bridge

结合广州南沙凫洲大桥的工程概况,介绍了真空压浆技术的原理及其施工工艺,提出了保证孔道内浆体密实、饱满的措施,以达到清除孔道内浆体的气泡,减少孔隙,提高桥梁安全性和耐久性的目的。

Combined with the general engineering condition of Fuzhou bridge in Nansha Guangzhou, the author intrcxuces the principle of vacuum mud-jacking technology and its construction technology, and puts forward the measure to ensure dense and plump slurry in pore canal, in order to clean bubbles inside the slurry in pore canal, to reduce small opening, and to improve security and durability of the bridge.
