Description of the Related Art At present, there are various types of underground continuous walls such as RC underground continuous walls, soil cement column walls, steel underground walls, and precast underground walls. These underground continuous walls mainly function as earth retaining walls or water blocking walls.

ント部分の止水が不完全となりがちである。However, even if it has a sufficient waterproofness for the purpose of construction, if it is intended to provide a more advanced or 100% complete waterproofness, the underground continuous wall will not be used. Is not enough. The RC underground continuous wall has a sufficient function in terms of strength due to the structure made of reinforced concrete, but is expected to have complete waterproofness in the future due to problems such as material problems, construction failure or cracks. I can't. In addition, the soil cement column wall is difficult to complete due to the fact that water leaks from a part of the wall due to the presence of defective laps, poor stirring and cracks. Furthermore, in the case of a precast underground wall, even if the plate itself has perfect water-blocking properties, there is a concern about water leakage from the connection site. Steel underground walls tend to have incomplete water stoppage at the joints.
