Installation and Usage Instructions
During installation, the perforated grouting pipes should be positioned and spaced according to design requirements. Generally, the pipes are drilled along the tunnel’s longitudinal profile at an external insertion angle of 10° to 30°. The spacing between the pipe rings should be between 200 cm to 500 cm.
