浅谈高压定喷截渗墙在堤防防渗工程中的应用

Talking about the Application of High Pressure Fixed Spray Cutoff Wall in Anti-seepage Engineering of Dyke

高压定喷截渗墙是由定喷形成板状墙段,并依照不同角度彼此搭接起来,最终形成的地下截渗防渗墙,具有良好的防渗效果及耐久性。高压定喷灌浆施工简便、机械化程度高、施工截渗性好,因此在堤防防渗工程中得到广泛的应用,本文以某堤防堤身防渗加固施工为例,对二管法高压定喷截渗墙的施工工艺、施工过程控制及成墙后质量检验等方面进行探讨。

High-pressure fixed spray cutoff wall is formed by fixed spray to form a plate-shaped wall segment,and overlaps each other according to different angles.The resulting underground cut-off seepage prevention wall has good anti-seepage effect and durability.The high-pressure fixed-jet grouting has the advantages of simple construction,high degree of mechanization,and good construction interceptibility.Therefore,it has been widely used in embankment anti-seepage projects.The construction technology of the seepage wall,the control of the construction process and the quality inspection after the wall is discussed.
