帷幕灌浆技术在桥墩施工中的应用

Application of Curtain Grouting in Bridge Pier Construction

摘要:

对于在砂卵石含量高、粒径较大的地层进行桥墩施工，多利用围堰法，围堰能否正常施工，则其外围的截防渗措施及施工工艺对防渗效果至关重要。桂林漓江南洲大桥通过设计方案比选，采用双液注浆帷幕灌浆技术进行截防水施工，取得了良好的效果，可为同类工程施工提供借鉴依据。

Abstract:

Cofferdam method is often applied for bridge pier construction in the formations with big sand-pebble particles, peripheral anti-seepage method and the construction technology are very important for anti-seepage effect. Bi-slurry curtain grouting technology was selected for Nanzhou bridge of Guilin, the ideal application could be reference to similar projects.
