摘要
在振动切刀下部安装有定喷的喷嘴,振动切槽之前,超前进行定喷,将振动切槽与定喷两种工艺综合成一种工艺,构成一种新的薄防渗墙的施工工艺——振动切喷技术。介绍了该新技术在重庆草街航电枢纽工程中的应用情况,实践证明,此工艺提高了防渗墙的施工效率与成墙质量。
Directional jetting nozzles are under the vibrating cutters, directional jetting is carried before vibrating cutting for trenching. Vibrating cutting and directional jetting are combined into one technology; a new construction technology for thin cutoff wall was formed. The paper introduced the application of vibrating cutting technology in navigation-power junction of Chongqing, which improved the construction efficiency and quality.
