Abstract
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.关键词
