尾矿渣填区袖阀管及高压旋喷桩加固成孔技术

On consolidation and pore-forming technique of sleeve valve and high pressure jet grouting pile at tail slag filling area

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.
