The main frame 2 includes a first frame 21, a second frame 22, and a connector 23. The first frame 21 and the second frame 22 are spaced apart from each other. The first end of the connector 23 is rotatably connected to the first frame 21, and the second end is rotatably connected to the second frame 22. The first frame 21 is connected to the traction component 1. The mounting part 3 is disposed on the main frame 2 and is used to install the pore water pressure gauge. The traction component 1 provides traction force for the auxiliary retrieval and placement device for the pore water pressure gauge to realize the lifting and lowering of the device in the borehole.
[0033] When the pore water pressure gauge auxiliary pick-up and drop device encounters resistance from the transversely moving soil layer within the borehole during the pick-up and drop of the pore water pressure gauge, the connecting piece 23 and the second frame 22 can rotate relative to the first frame 21 to avoid the transversely moving soil layer, thereby reducing the resistance caused by the transversely moving soil layer and preventing the pore water pressure gauge auxiliary pick-up and drop device from getting stuck in the borehole. This allows the pore water pressure gauge to be smoothly placed to or removed from the designed depth of the borehole. Accordingly, the pore water pressure gauge can be placed to the designed depth of the borehole, improving the accuracy of the monitoring results of the water pressure in the soil around the pile.
