Description
JNC has joined the international joint project, the TSX project, with AECL at the Underground Research Laboratory (URL) in Canada. Full-scale sealing technologies are applied to an underground tunnel in the TSX project. Regarding clay grouting, which supports the performance of the clay plug, a grouting experiment in the Excavated Damaged Zone around the tunnel was performed in the TSX project. A pre-injection test was the trial for the development of the grouting procedure, and the injection test was to evaluate the grouting effectiveness of the grouting in the EDZ around the tunnel. The results of the experiments showed the efficiency injection concentration of the grout slurry was between 4.0 and 6.0wt%. Grouted EDZ had lower hydraulic conductivity than that before grouting.
