Abstract

The invention relates to a slurry extractor and an extraction method thereof. The slurry extractor comprises a cylinder barrel, a second lifting rope and a sleeve pull rod; the top of the cylinder barrel moves up and down through the traction of the sleeve pull rod and the second lifting rope. The slurry extractor and the extraction method thereof are characterized in that a slurry inlet is formed in the center of the top of the cylinder barrel, a slurry seal piece matched with the slurry inlet is arranged in the cylinder barrel, a seal piece pull rod is vertically fixed in the center of the slurry seal piece, the seal piece pull rod moves up and down through the traction of a first lifting rope, a lifting screw is arranged in the center of the bottom of the cylinder barrel, and the lifting screw is equipped with an annular balancing weight. The slurry extractor can be lowered to different depths of slurry liquid and simultaneously complete grouting and sealing of the slurry liquid, and the independence of the slurry liquid at the depth is guaranteed. Meanwhile, the balancing weight of the slurry extractor can be increased according to the depth, density and the size of buoyancy of the extracted slurry liquid, and it is guaranteed that the slurry extractor can sink to a specified depth, so that the extraction work of the slurry liquid at different depths can be completed.

Description

[technical field] [0001] The invention relates to the technical field of mud extractors, in particular to a mud extractor and its extraction method. [Background technique] [0002] The mud extractor is a device used to extract mud, which is mainly used in the detection of mud parameters when foundation piles are formed into holes in civil engineering construction. In the construction of civil pile foundation, the method of mud wall protection is often used for the hole formation of cast-in-place piles. The ratio parameters of mud have a great relationship with the hole-forming and forming quality of cast-in-place piles. The detection of mud parameters has become an important means of quality control of bored cast-in-place piles. . For this reason, how to obtain mud in the foundation pile forming hole becomes a problem that has to be faced in the project. The method used in the past is to randomly use a container to take some samples on the surface of the slurry as a test s...
