Title:
電気比抵抗検知装置およびソイルセメント体の品質管理方法
Document Type and Number:
Japanese Patent JP6699135
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electric specific resistance detector and a quality management method for a soil cement body using the electric specific resistance detector when constructing the soil cement body in a ground, the electric specific resistance detector being capable of accurately detecting an agitation and mixed state of the ground and a cement-based solidification material in the soil cement body when not yet cured.SOLUTION: An electric specific resistance detector includes: a specific resistance measuring instrument with a specific resistance sensor and a radio transceiver that sends at least data information obtained from the specific resistance sensor; a ground management device with a transceiver for receiving the information sent by the radio transceiver; a fitting member with a frame fixing part fixed on a frame of an agitation mixer and a support part for supporting the specific resistance measuring instrument. The fitting member is made of an electrically insulating material, and includes the frame fixing part fixed on the frame and the support part for supporting the resistance measuring instrument. Furthermore, an interval between the support part and the frame fixing part is set so as to enclose a measurement space formed around the specific resistance sensor.SELECTED DRAWING: Figure 5
