IMPROVEMENT BODY MANAGEMENT SYSTEM AND IMPROVEMENT BODY MANAGEMENT METHOD
To make it possible to improve complete shape accuracy by improving the position accuracy of a boundary between a ground improvement body and the ground.SOLUTION: An improvement body management system is provided that comprises: salt that is added to an existing ground G together with improvement agent when forming a ground improvement body 2; an electric transmitter 4 that is formed during formation of the ground improvement body 2 in a manner of extending in the vertical direction and inserted into an injection hole 2a for improvement agent, and that transmits electricity from the injection hole 2a toward the ground improvement body 2; an electric receiver 5 that is inserted into the injection hole 2a into which the electric transmitter 4 is inserted, and that receives reflected electricity E2 that is transmission electricity E1 which is transmitted from the electric transmitter 4 and reflected on a boundary K between the ground improvement body 2 and the ground G; a data processing unit 6 that calculates specific resistance values for the ground improvement body 2 and the ground G therearound based on the reflected electricity E2, and calculates a horizontal distance between the injection hole 2a and the ground G using the specific resistance values in order to obtain the boundary K. The salt has an equivalent conductivity that is equal to or higher than ionized calcium that is included in the improvement agent.SELECTED DRAWING: Figure 1
【課題】地盤改良体と地盤との境界面の位置精度を高めて、出来形精度を向上させることができる。【解決手段】地盤改良体２の造成時に改良剤とともに現地盤Ｇに添加される塩と、地盤改良体２の造成中に形成され鉛直方向に延在して改良剤の注入孔２ａに挿入され、注入孔２ａから地盤改良体２に向けて電気を発信する電気発信器４と、電気発信器４が挿入された注入孔２ａに挿入され、電気発信器４で発信した発信電気Ｅ１が地盤改良体２と地盤Ｇとの境界面Ｋで反射した反射電気Ｅ２を受信する電気受信器５と、反射電気Ｅ２に基づいて地盤改良体２とその周囲の地盤Ｇとの比抵抗値を算出し、比抵抗値から注入孔２ａと地盤Ｇとの間の水平距離を算出して境界面Ｋを求めるデータ処理部６と、を備え、塩は改良剤に含まれるイオン化カルシウムと同等以上の当量伝導率を有する構成の改良体管理システムを提供する。【選択図】図１
