Abstract: A permeability test device is provided to test permeability of tunnel lining concretes with a simple method by manufacturing a tunnel lining concrete sample in the same conditions as a tunnel construction site. A permeability test device comprises a sample installation unit(10), a pressurized water supply unit(20) and a water flow metering unit(30). The sample installation unit installs lining concretes manufactured in the same conditions as a tunnel site to be tested. The pressurized water supply unit is coupled to one side of the sample installation unit in a sealed state, and applies the pressurized water to the lining concretes. The water flow metering unit collects water passing through the lining concretes of the sample installation unit and discharged to the other side of the lining concretes, and measures the flow rate.
