CONFIRMATION METHOD OF AGITATING/MIXING STATUS IN GROUND IMPROVEMENT BODY
To provide a confirmation method of an agitating/mixing status in a ground improvement body which can correctly and simply confirm an agitating/mixing status in a ground improvement body whether a ground improvement body constructed underground is correctly constructed.SOLUTION: A confirmation method of an agitating/mixing status in a ground improvement body for confirming an agitating/mixing status in a ground improvement body includes: a first capturing step of capturing a state in a ground at an insertion place of a pipe rod 1 with a camera 11; a second capturing step of capturing a state in a ground at a place separated from the insertion place of the pipe rod 1 by a prescribed distance with the camera 11; a third capturing step of capturing a state in a ground at a place outside a ground improvement body to be constructed with the camera 11; an image processing step of calculating a digitized image brightness from each image of the state in the ground captured in the first capturing step, the second capturing step, and the third capturing step; and a confirmation step of comparing the digitized image brightness calculated in the image processing step with an index obtained therefrom, to confirm an agitating/mixing status in the ground improvement body.SELECTED DRAWING: Figure 4
【課題】地盤改良において、地盤中に造成した地盤改良体が正しくできているかどうかの地盤改良体の攪拌混合状況を正確にかつ簡単に確認することのできる地盤改良体の攪拌混合状況確認方法を提供する。【解決手段】地盤改良体の攪拌混合状況を確認する地盤改良体の攪拌混合状況確認方法であって、管ロッド１の挿入地点の地盤中の様子をカメラ１１で撮影する第一撮影工程と、管ロッド１の挿入地点から所定距離離れた地点の地盤中の様子をカメラ１１で撮影する第二撮影工程と、造成する地盤改良体の外側の地点の地盤中の様子をカメラ１１で撮影する第三撮影工程と、第一撮影工程、第二撮影工程、第三撮影工程で撮影したそれぞれの地盤中の様子の画像より、数値化した画像明度をそれぞれ算出する画像処理工程と、画像処理工程で算出した数値化した画像明度とそこより求める指標とを比較し、地盤改良体の攪拌混合状況を確認する確認工程とを有する。【選択図】図４
