高压旋喷止水帷幕在粉细砂层中的实施及探索

Implementation and Exploration Regarding Swirl Ejection Water Retaining Curtain Technology in the Underground Fine Sand Layer

通过广州地铁六号线东湖站连续墙逆作法施工实例,取得了在粉细砂层中成功实施旋喷止水帷幕的施工经验,并推广应用到其它渗漏水较严重的工地,效果良好,为类似地质条件下的止水帷幕施工提供了一个思路。

Through constructing the underground diaphragm wall of Donghu Station of Metro 6,experience has been gained in applying water-stop curtain （swirl ejection water retaining curtain） technology in the undergoumd fine sand layer. And it has been succeeded in expending to other construction site. A train of though has been provided under geological conditions to have water-stop curtain construction in similar way.
