The utility model discloses a collecting device for an underground water sample with fixed depth, which comprises a wellhole (1) and a well cover (4), wherein the well cover (4) is arranged on the upper end of the wellhole (1), and a percolating section (2) is arranged at the lower section of the wellhole (1). The wellhole (1) having an integral structure is adopted and is used in a combination way with different length specifications so as to meet the requirements on layering collection of a superficial layer underground water sample. 3-5 sampling wells with different depth are arranged at each sampling point, and water samples of underground water at different depth can be collected by the percolating section (2) of the wellhole (1), thus realizing the correct layering collection. The collecting device is simple in structure, convenient for use, and low in manufacturing cost, and is a practical and fast and convenient layering collecting device for the underground water sample.
