摘要
北京市南水北调配套工程河西支线工程施工第三标段进出水管线基础为杂填土地层,填土地层力学性质不稳定,采取袖阀管注浆加固法进行基础加固,该注浆方法效果明显,很好地改善了地层性质,明显提高地基承载力。文章根据工程实际情况,对袖阀管注浆工艺进行了介绍。
The inlet and outlet pipes of No.3 bidding section of Hexi branch works of South-to-North Water Transfer Supporting Project fall on miscellaneous fill soil layer with unstable mechanical properties.Sleeve valve pipe grouting method was adopted for foundation reinforcement,rendering significant effects and improving the stratum properties,significantly increasing the foundation bearing capacity.An introduction was made on the sleeve valve pipe grouting technique combined with the actual situation of project.
