Fix them above the measuring rope 7. Avoid disturbing the hole wall during the hanging process, thereby causing the hole to collapse. Then slowly pull up the second pull rope 12 until the tank body turns from vertical to horizontal in the mud hole, fix the second pull rope 12, and no longer lift it. (Depending on different needs, this device can sample vertically or horizontally, and this step is omitted for vertical sampling). Then pull the first pull rope 6, transmit force through the second pull ring 17, and the spring 2 is pulled and extended. The sealing cover 15 slowly opens, and the mud in the hole enters the sampling tank. Then slowly release the first pull rope 6, the spring 2 shortens and returns to its original state, and the sealing cover 15 is closed. Then release the first pull rope 6, and the tank body turns from horizontal to vertical in the mud hole. (This step is omitted when sampling vertically), loosen the measuring rope 7 on the resting reinforcement, and pull the measuring rope 7, fish out the sampling tank, pour the sample slurry in the filling body into the mud storage container, and properly store the sample for test use. It should be noted that the device is suitable for various types of pile foundation construction environments.
