袖阀注浆处理软土地基施工技术

Using sleeve valve grouting to treat soft foundation

袖阀注浆是目前一种比较先进的注浆工艺,其适应性强,对砂层、粉土、淤泥层等均能达到较好的注浆加固效果。某新建机场飞行区地基存在淤泥及淤泥质土等不良地质体,采用了袖阀注浆工艺对淤泥质土体进行加固处理,取得了良好的效果。

The sleeve valve grouting technology is an advanced technique at present and has strong adaptability. It can produce good reinforcement effectiveness for those foundations such as sand, silt and mud layer foundations. For example, an airport foundation is full of silt and mud layer. Then the sleeve valve grouting was used to reinforce it and a good result was gained.
