A casing pipe extends in a vertical direction, and two adjacent casing pipes are connected by a plurality of link mechanisms; the link mechanism includes two supports, the two supports are hinged by a first pin to form a hinged portion, an upper end and a lower end of the link mechanism are hinged to two adjacent casing pipes by second pins separately, a sensor is fixed to the link mechanism, and the link mechanism has an initial state of extending in the vertical direction and an extending state in which the hinged portion extends outwards to be located on an outer side of the casing pipe; a driving mechanism drives a push portion to move towards the link mechanism; and a downward pressing apparatus is used for pressing a top end of the topmost casing pipe downwards to push the hinged portion into a side wall of the borehole.

Arrangement device for multiple sensors outside borehole of sliding mass and arrangement method

An arrangement method for deformation of a locked patch crack of a rock slope, includes: connecting a filling pipeline on a bladder-type monitoring probe to a mortar guiding pipe through an automatic locking and unlocking device, clamping a portion to be clamped on a bladder by a clamping assembly, driving a clamping driving mechanism to move towards an adit by a push driving mechanism, and pushing the bladder into the adit; injecting cement mortar into the bladder through the mortar guiding pipe by utilizing a high-pressure injection machine to expand the bladder until an upper surface and a lower surface of the bladder abut against an upper surface and a lower surface of the adit, and making a monitor on the bladder abut against the upper and lower surfaces of the adit; and arranging a plurality of bladder-type monitoring probes in an array in the adit.

Monitoring device for deformation of locked patch crack of rock slope and arrangement method

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.
