Experiment research about grouting liquid influences the slurry in the drilling and grouting method parallel operations

Direct at the problem that the grouting liquid corrodes and pollutes the slurry and influences the normal drilling in the process of of boring method and grouting method parallel operations, a serises of experiments were carried out in the laboratory. Through experiments, this thesis analyses the result the grouting liquid influences the slurry, and advises to set up precautionary measure such as slurry abservation system.
