袖阀管注浆法通过特殊的工艺分段、分次、间歇、定量地将水泥浆液注入杂填土地层的孔隙和松散层中，被加固土体通过水泥浆液的相互作用形成了上下连续且相对密实稳定的固结体，从而使得被加固土体的密实度增大、压缩性降低、抗渗性能提高，增强了地基土的整体性和防渗能力。介绍了袖阀管注浆加固作用机理、袖阀管注浆法施工过程及质量控制要点，该方法在某防洪墙工程基础底面以下杂填土地基防渗问题处理中的应用情况：工程施工完成后经两次洪水考验，防洪墙后未发生渗水、管涌和其他险情，加固效果显著；该方法加固处理后的杂填土地层的防渗效果显著，满足设计要求。
袖閥管註漿法通過特殊的工藝分段、分次、間歇、定量地將水泥漿液註入雜填土地層的孔隙和鬆散層中，被加固土體通過水泥漿液的相互作用形成瞭上下連續且相對密實穩定的固結體，從而使得被加固土體的密實度增大、壓縮性降低、抗滲性能提高，增彊瞭地基土的整體性和防滲能力。介紹瞭袖閥管註漿加固作用機理、袖閥管註漿法施工過程及質量控製要點，該方法在某防洪牆工程基礎底麵以下雜填土地基防滲問題處理中的應用情況：工程施工完成後經兩次洪水攷驗，防洪牆後未髮生滲水、管湧和其他險情，加固效果顯著；該方法加固處理後的雜填土地層的防滲效果顯著，滿足設計要求。

Sleeve valve pipe grouting section,through special process and intermittent,quantitatively injects the cement grout into mixed backfill layer porosity and loose layer,reinforced soil cement slurry through the interaction and the formation of consolidation body becomes continuous and relatively dense and stable,so that by soil compaction degree increase,compressibility is reduced,anti permeability increased,enhanced soil in-tegrity and anti-seepage capacity. The sleeve valve pipe grouting reinforcement mechanism,the sleeve valve pipe grouting construction process and control,This method in a flood the wall project of foundation bottom fill application processing problems of land based in the anti-seepage reinforce-ment show that:After the two flood,flood control wall without water seepage,piping and other dangerous situation,strengthening effect;the meth-od of reinforcement of miscellaneous fill soil anti-seepage effect is remarkable,and can meet the design requirements.
