SOIL IMPROVEMENT STATE MONITORING SYSTEM AND SOIL IMPROVEMENT STATE MONITORING METHOD

To provide, e.g., a system that can confirm the quality of ground improvement construction while enhancing the wireless communication efficiency.SOLUTION: The rotational frequency of a shear assist blade 14 is measured in time series by means of a state monitoring sensor 211, and time series data of the rotational frequency of the shear assist blade 14 during ground improvement construction is stored and held in a first storage device 212. If a first specified condition is satisfied, the time series of the rotational frequency of the shear assist blade 14 (time series data of the rotational frequency of the shear assist blade 14 during the ground improvement construction) is read out of the first storage device 212, and sent from a first state monitoring module 21 to a second state monitoring module 22 in a wireless manner.SELECTED DRAWING: Figure 1 【課題】無線通信効率の向上を図りながら、地盤改良施工の品質を確認しうるシステム等を提供する。【解決手段】状況監視センサ２１１により、剪断補助翼１４の回転数が時系列的に測定され、地盤改良施工中の剪断補助翼１４の回転数の時系列データが第１記憶装置２１２に記憶保持される。第１指定条件が満たされた場合、剪断補助翼１４の回転数の時系列（地盤改良施工中の剪断補助翼１４の回転数の時系列データ）が第１記憶装置２１２から読み出されて第１状況監視モジュール２１から無線方式で第２状況監視モジュール２２に宛てて送信される。【選択図】図１
