The invention discloses a buried deep circulation battery pack, which comprises a battery, an indirect wire, an air duct, an output wire, a T-shaped pipe joint and an L-shaped pipe joint. The batteryis a narrow and long lead-acid battery, four batteries of the same specification are divided into two pairs connected into a group, the positive and negative pole terminals of adjacent batteries are connected with indirect wires, and the remaining positive pole terminals of the first battery and the remaining negative pole terminals of the last battery are respectively externally connected with output wires. The ventilation interface of the first battery is sealed with an L-shaped pipe joint, and the ventilation interface of the other three batteries is sealed with a T-shaped pipe joint. Eachpipe joint is serially connected with a guide pipe to form an external ventilation channel, and the outlet of the guide pipe is exposed to the ground. A retainer ring, a sealant layer and a polar marking adhesive layer are added on the outer wall of the pole terminal of the battery from the inside to the outside, so that the insulation structure is reliable and the safety performance is guaranteed, and the requirements for buried installation of the communication base station are completely met.
