The invention discloses a deep soil distributed collector with a freezing function, and relates to the technical field of environmental pollution investigation. A vertical downward drilling support driving unit for driving a drill rod to vertically drill into a soil layer is mounted above a crawler; a horizontal sampling freezing driving unit which is used for carrying out distributed sampling and freezing sampled soil to prevent organic pollutants from volatilizing is jointly installed at the bottom end and in the drill rod, and a structure which is used for horizontally and transversely collecting soil samples around a deep soil layer in an extending mode is further arranged on the drill rod in a carrying mode, so that one-time vertical downward drilling is achieved; according to the method, soil samples at multiple surrounding point locations are collected at the same time, large drilling equipment does not need to be used for drilling for multiple times to obtain multi-point soil samples, in addition, whe
