The viscosity, sand content, specific gravity and the like of the slurry can influence the effect of the slurry retaining wall, which directly influences the engineering quality of the diaphragm wall. Therefore, the slurry in the trench section needs to be sampled, and relevant parameters (viscosity, sand content and specific gravity) of the slurry are tested, and the tested slurry parameters meet relevant national, industrial and local standard specifications, so that a slurry sampling device is urgently needed to sample in the construction process of the underground diaphragm wall. However, the diaphragm wall excavation process may traverse different geological layers. For different stratum conditions, sampling and testing are carried out on mud at different depths (stratum conditions). The current mud sampler of diaphragm wall in underground can only sample the mud of top layer and bottom, can not sample the mud of the different degree of depth.
