The Legend Pipe method was researched and developed to reduce groundwater and prevent landslides and liquefaction by utilizing a subsidy from the Ministry of Land, Infrastructure, Transport and Tourism. However, since the effect of this method has not been confirmed, a construction experiment was conducted in Hamamatsu City, Shizuoka Prefecture to lower the groundwater level of the liquefied ground. In this paper, it was clarified from the experimental results that the groundwater level drops in a short time, there is no land subsidence, and it is effective as a countermeasure against liquefaction.
