EXCAVATION AND AGITATION DEVICE, AND EXCAVATION AND AGITATION METHOD
To provide an excavation and agitation device capable of accurately confirming an agitation and mixture status of a ground improvement body in real time in parallel to the agitation and mixture.SOLUTION: An excavation and agitation device, designed to discharge a cement slurry to which a water-soluble fluorescent dye of a prescribed concentration is added into a ground, comprises: a rotating shaft 3 that rotates in ground around a vertical axis; an excavation blade 5 that is axially attached to the rotating shaft 3 and excavates soil; a light source 6 that radiates black light onto a ground improvement body in the ground; and a measuring device 7 that measures the ground improvement body irradiated with the black light from the light source 6. The light source 6 and the measuring device 7 are raised and lowered integrally with the excavation blade 5. The excavation and agitation device comprises a control portion 20 that compares data output by the measuring device 7 with a predetermined threshold, determines whether a mixture state of the cement slurry is permissible or not, and allows the excavation blade 5 to proceed when the mixture state is permissible.SELECTED DRAWING: Figure 7
【課題】 地盤改良体の撹拌混合状況を、撹拌混合と並行してリアルタイムで正確に確認できる掘削撹拌装置を提供する。【解決手段】 本装置は、所定濃度の水溶性蛍光染料を添加したセメントスラリーを地中に吐出する掘削撹拌装置であって、地中において鉛直軸を中心として回転する回転軸３と、回転軸３に軸着され土砂を掘削する掘削翼５と、地中において地盤改良体にブラックライトを照射する光源６と、光源６によりブラックライトを照射される地盤改良体を計測する計測器７とを備え、光源６と計測器７は、掘削翼５と一体的に昇降し、計測器７が出力するデータと所定閾値とを比較し、セメントスラリーの混合状態の可否を判定し、混合状態が可であるとき、掘削翼５を歩進させる制御部２０を備える。【選択図】 図７
