Present Application and New Advances of HighPressure Jet Grouting Technique

The process, method and application scope of the high pressure jet grouting technique are de-scribed. A cornparison is given to the equipment and parameters employed in the single, dual and triple pipegrouting methods and their grouting effects,with field cases listed. New advances having been made in the theo-ty, equipment,technique and the application scope are introduced. At length,some problerns existing in the en-gineering application are put forward for the future discussion and solution.
