In the construction of a road tunnel, to prevent the tunnel entrance settlement, ground improvement work was conducted as a countermeasure against settlement at the tunnel entrance. Due to the bearing layer being 14m deep, we adopted Power Blender method for the depth of 0 to 8m, and the Column Jet Grouting method for the depth of 8 to 14m. (Location: Fukushima) |
