Abstract
The present disclosure relates to a device for laying out a prefabricated magnetic field and a method for responding state of a slip mass in the prefabricated magnetic field. The device may include a traction mechanism, a control mechanism and a layout probe. The layout probe may include a shell, a circuit board and at least one set of layout mechanism equipped in the shell. The layout mechanism may include a cartridge, a screw pole, an electromagnet, a driving mechanism and a pressing mechanism. The traction mechanism may lay down the layout probe to a default location of a drill hole. The control mechanism may control the driving mechanism to transmit an uppermost permanent-magnet in the layout probe to the cartridge nozzle and be attracted by the electromagnet. The pressing mechanism may move the electromagnet which presses the permanent-magnet in the inner wall of the drill hole.
