To accurately measure the developed shape of a soil improved body to be developed by using a cement-based deep layer mixture treatment method, during the development.
In this measuring method for the developed shape of the soil improved body to be developed by high-pressure injection of hardening material liquid and the like from an injection rod 2 inserted into soil, a sound wave oscillator (4) and an oscillation receiver (5) are inserted into the soil where the soil improved body is developed, and during injecting the hardening material liquid into the soil to develop the soil improved body, sound waves oscillated from the sound oscillator (4) and reflected from a boundary surface between the soil and the soil improved body are continuously received by the oscillation receiver (5) to measure the developed shape of the soil improved body, specifically, to measure the diameter of the soil improved body. The sound wave oscillator (4) and the oscillation receiver (5) are inserted into the soil together with the injection rod 2.
