The invention aims to provide a carrier pile construction method. According to the characteristic that the soil layer where the pile end is located is harder, punning and compaction are conducted on the soil body of the pile end directly through kinetic energy, and the requirements of multiple geological conditions and design requirement change are met through the improvement of the pore-forming mode and the pile-forming mode. To achieve the purpose, the construction method includes the steps that 1, a pile casing or an outer tube is sunk into the set depth through power at the pile position; 2, punning is conducted on the soil body at the bottom of a pile hole through the hammering kinetic energy of a heavy hammer or an inner tube in the pile casing or the outer tube, and the soil body of the pile end is reinforced and compacted; 3, punning is conducted repeatedly, the penetration of several times of striking of the heavy hammer or the inner tube is measured, when the penetration measuring value meets the design value, punning is stopped, the soil body, within certain depth and range, below the pile end is reinforced and compacted, a pile end carrier is formed, and the equal calculation area Ae of the carrier pile is achieved; 4, pile body construction is conducted.
