Introducing SWP method and VPRW method as foundation work and groundwater control technologies!

This document presents information regarding "Groundwater Measures in the Underground Main Works of the Sendai Airport Access Railway." In this construction, the "Super Well Point Method" was adopted as the groundwater lowering method, and the "Vacuum Press Type Recharge Well Method" was used as the treatment method for returning pumped groundwater back underground. We introduce the methods that have also resolved issues such as the high concentration of dissolved iron in groundwater, starting from the comparative examination stage.
