This construction involved expanding the multi-purpose space by removing the bearing wall of the underground hallway. A saddle was installed in the top central part of the wall and a non-adhesive tension reinforcement was used to pull the wall from each side. This was opposite than when we worked on the Hyunsu aqueduct.
