[0002] At present, the commonly used manual mud extraction tool for a cast-in-place pile is difficult to extract mud at different depth positions, and has poor sealing performance, thereby causing the extraction tool to sink in the mud, and the mud to leak out or enter the mud at a non-extraction position during lifting, so that the ideal mud extraction effect cannot be achieved, and the mud detection test is inaccurate.

[0003] The patent application document with the application number CN201510052381.2 discloses a mud extractor and an extraction method thereof, which comprises a cylinder, a second lifting rope, and a sleeve pull rod. The top of the cylinder is pulled up and down by the sleeve pull rod and the second lifting rope. The top of the cylinder is provided with a mud inlet in the center. The cylinder is provided with a mud seal that is matched with the mud inlet. The mud seal is vertically fixed with a seal pull rod in the center. The seal pull rod is pulled up and down by a first lifting rope. The bottom of the cylinder is provided with a weight lifting screw. The weight lifting screw is provided with an annular counterweight. The mud extractor can be lowered to different depths of the slurry, and simultaneously complete the injection and sealing of the slurry, thereby ensuring the independence of the slurry at the depth. Meanwhile, the counterweight of the slurry extractor can be increased according to the depth, density, and buoyancy of the extracted slurry, so that the mud extractor can be sunk to the specified depth, thereby completing the extraction of the mud at different depths. However, the document has the following defects:

[0004] 1. The mud seal pulled by the first lifting rope is difficult to be coaxial with the cylinder in actual use, and the sealing effect is not ideal, which may cause mud leakage or mud inflow during lifting.

[0005] 2. The first lifting rope and the second lifting rope are in a split structure, lack of cooperative matching, and are difficult to operate. On the one hand, the depth of the cylinder needs to be controlled, and on the other hand, the mud seal needs to be sealed with the cylinder. CONTENT OF THE INVENTION
