Zusammenfassung:PROBLEM TO BE SOLVED: To reduce the number of withdrawal wellholes.SOLUTION: A withdrawal method of underground water is a method to withdraw underground water from a first block area R1 and a second block area R2 of a subsoil 10 which is segmented by a grid-like subsoil improvement body 22. The underground water is withdrawed from the second block area R2 from a withdrawal wellhole 16 formed in the first block area R1 via a water passage W formed in the grid-like subsoil improvement body 22.SELECTED DRAWING: Figure 2 【課題】本発明は、揚水井戸の本数を削減することを目的とする。【解決手段】地下水の揚水方法は、格子状地盤改良体２２によって区画された地盤１０の第一区画領域Ｒ１及び第二区画領域Ｒ２の地下水を汲み上げる地下水の揚水方法であって、第一区画領域Ｒ１に設けられた揚水井戸１６から、格子状地盤改良体２２に設けられた通水部Ｗを介して、第二区画領域Ｒ２の地下水を汲み上げる。【選択図】図２
