尾矿渣填区袖阀管及高压旋喷桩加固成孔技术

摘要

以某施工工程为例，依据袖阀管及高压旋喷桩加固成孔施工技术原理，从施工准备、袖阀管注浆加固、高压旋喷桩加固、旋挖桩成孔及质量检测等方面介绍了其施工工艺及操作要点，并分析了施工中的注意事项，以供参考。%Taking some construction project as the example,the paper introduces the construction craft and operation points from the construction preparation,sleeve valve pipe grouting consolidation,consolidation of high pressure jet grouting,pore-forming of jet grouting,and quality detec-tion by referring to the construction technical principles for the sleeve valve and high pressure jet grouting,and analyzes the precautions in the construction,so as to provide some reference.
