In this sampling device for deep geological survey, after the sampling drill bit penetrates into the soil layer at a specified depth, the sampling drill bit is rotated in the opposite direction to the unidirectional sampling barrel, and after the soil sample enters the sampling drill bit from the barrel mouth of the unidirectional sampling barrel, the rotation is stopped, the sampling rod group is taken out, the sampling rod is removed, and the soil sample is taken out from the sample taking hole, thereby realizing the functions of deep geological survey and sampling;
