MANAGEMENT METHOD OF CONSTRUCTION OF SOIL IMPROVEMENT BODY
To provide a management method of construction of a soil improvement body which can perform discrimination of a filling state of a hardener or a chemical into a ground in real time and with high accuracy.SOLUTION: A management method of construction of a soil improvement body comprises: a first step of installing a ground insertion board 7 provided with a sensor 20 detecting an injected cement milk M into the ground in which a soil improvement body T is constructed; and a second step of, after the first step, in constructing the soil improvement body T in the ground, detecting the injected cement milk M by the sensor 20 provided in the ground insertion board 7 and discriminating a filling state of the cement milk M into the ground based on the detection result. The ground insertion board 7 is formed of a water impermeable material which has low rigidity and to which vibration and heat are hardly transferred, has a plate shape with a plurality of long holes 11 extending in a longitudinal direction, and in which the sensor 20 is disposed in the long hole 11.SELECTED DRAWING: Figure 9
【課題】地盤中への硬化材又は薬液の充填状態の判別を、リアルタイムかつ高い精度で行うことができる地盤改良体の造成管理方法を提供する。【解決手段】地盤改良体Ｔが造成される地盤中に、噴射したセメントミルクＭを検出するセンサー２０を装着した地盤挿入ボード７を設置する第１工程と、第１工程の後、地盤中に地盤改良体Ｔを造成する際に、地盤挿入ボード７に装着したセンサー２０で噴射したセメントミルクＭを検出し、当該検出結果に基づき地盤中へのセメントミルクＭの充填状態を判別する第２工程と、を有する地盤改良体の造成管理方法である。地盤挿入ボード７は、剛性が低くて振動や熱が伝わりにくい非通水性の材料で形成されるともに、長手方向に延在する複数の長孔１１を備えた板状で、センサー２０が長孔１１内に配置されている。【選択図】図９
