We will introduce a case where a seal drain was installed to cover the water leakage next to the steel plate, and the construction was carried out to direct the water to the shoulder.

This is an introduction to a case of leak prevention work conducted by "Sen Dousuiko" at the Kageji Tunnel in Ono City, Fukui Prefecture. At the site, water leakage was occurring from the side of the existing steel plate (5mm thick). On the other hand, since the removal of the existing steel plate was not possible and the tunnel cross-section was small, there was a request to minimize protrusion from the wall, necessitating effective countermeasures. By installing seal drains, we were able to prevent water leakage, eliminating dripping onto the road. [Challenges] ■ Water leakage was occurring from the side of the existing steel plate (5mm thick) ■ Removal of the existing steel plate was not possible ■ Due to the small tunnel cross-section, there was a desire to minimize protrusion from the wall *For more details, please download the PDF or feel free to contact us.
