Groundwater lowering method associated with large-scale excavation work for the construction of a sewage treatment facility.

Adopting the "SWP" method for groundwater level lowering associated with excavation work! Contributing to dry work.

At the Hachioji Water Reclamation Center in the middle reaches of the Tamagawa River, the "Super Well Point Method" was adopted for groundwater lowering techniques in conjunction with the construction of a new treatment facility (western water treatment facility). After selectively operating based on excavation depth and groundwater lowering conditions, the groundwater level remained relatively stable overall. At this time, the pumping volume was also stable, and while maintaining this state, excavation of the floor surface at the deepest point was carried out. It was confirmed that there was no spring water at the floor surface and that it was in a dry state, indicating that the groundwater level at the excavation surface had been lowered to a significant depth.
