Japan, Sept. 16 -- DAIKI RIKA KOGYO KK,NITTOC CONSTR CO LTD has got intellectual property rights for 'MONITORING DEVICE AND MONITORING METHOD USED IN HIGH-PRESSURE INJECTION STIRRING METHOD.' Other related details are as follows:
Application Number: JP,2022-161290
Category (FI): E02D3/12,102
Stage: PROBLEM TO BE SOLVED: To provide a monitoring device and a monitoring method which can confirm an effective diameter of a soil improving body with high reliability.SOLUTION: A monitoring device 1 is used when a soil improving body S is constructed in a high-pressure injection stirring method for pulling up a filling pipe 3 inserted into a ground G while rotating the filling pipe 3 while injecting a harder from a nozzle 3a of the filling pipe 3, and thereby constructing the soil improving body S, and includes a rod 6 provided with an imaging mechanism 7 for imaging the harder injected from the nozzle 3a. The rod 6 is configured so as to be inserted into the ground G so that the imaging mechanism 7 becomes the same depth as a lower end improved by the harder injected from the nozzle 3a, on an outer edge part of a schedule effective diameter in the soil improving body S, and to be pulled up together with the filling pipe 3.SELECTED DRAWING: Figure 1 (Grant)
