Abstract
Taking collapse treatment of cavity rich-water of the Yesanguan Tunnel for example, the construction processes to treat collapse with the method of grouting solid in the condition of drainage and pressure decreasing were introduced. The machinery and equipment of drilling grouting as well as control measures of grouting process in the boundary conditions were also discussed, with a view to provide a reference for dealing with issues of similar projects.
