| 中文摘要: |
| 总结“三头小直径深层搅拌二次成墙法建造水泥土防渗墙施工技术”在多个堤身防渗小直径深层搅拌水泥土防渗墙工程中的应用情况，对搅拌头的钻头与喷浆方式进行了改进，经工程实践验证，改进后的搅拌头，有效降低了搅拌头的钻进扭力，使被搅动的成墙土料与喷入的水泥浆搅拌更均匀、充分，有较好的推广应用前景. |
| 英文摘要: |
| Based on summarizing the application of concrete cutoff wall construction technology of 3 heads small diameter deep mixing pile cut off wall secondary wall forming method in several dyke body concrete cutoff wall，the drill and gunite mode of stir head have been improved.Engineering practice shows that the improving stir head could reduce stir head’s drilling torsion effectively，and make wall forming soil and cement slurry stirred uniformly，fully.It should be popularized. |
