Measures against bulging and condensate recovery associated with the reconstruction of the cleaning plant.

Introducing examples of adopting the "SWP method" and "VPRW method" in factory reconstruction work.

In the reconstruction work of the Nerima Cleaning Plant of the Tokyo 23 Wards Cleaning Administrative Union, the "Super Well Point Method" and the "Vacuum Press Type Recharge Well Method" were adopted as measures against heaving and dry work, as well as for the treatment of pumped groundwater. As a result of using these two methods, the water levels of the confined groundwater and free water were lowered to the target level, preventing heaving and allowing excavation to proceed with dry work. Additionally, the pumped groundwater was able to be recharged through a recharge well. Furthermore, there was no decrease in the groundwater level in the shallow layer outside the retaining wall.
