The invention discloses a construction method for piles. The construction method includes the steps of implementation, pipe sinking, pouring, pipe drawing and the like. Construction is convenient, and the construction effect is good. By means of adjusting the compaction coefficient D, the form coefficient alpha and the bearing capacity coefficient m, environment friendliness is achieved, and the application range of the soft and hard soil area is widened; the shape and the size of an expansion head are guaranteed, soil around the expansion head can be reinforced and compacted, and the discreteness of the bearing capacity of the expansion head is overcome; and the bearing capacity of the expansion head is improved and guaranteed, the bearing capacity of the expansion head can be predicted, and pile bodies can be anchored into the expansion head to form expansion head anchor piles till the multistage expansion head is formed. Positioning, pipe sinking, pouring, tamping and extending and pipe drawing are conducted, multiple devices act in a streamlined manner, and work efficiency is improved. The inner tamping cast-in-place piles are constructed in the centers of the cement-soil piles, and restraint of the cement-soil piles in the hardening period is avoided; and a common pipe sinking process usually lasts for shorter than one day, the construction period of the construction method usually lasts for shorter than five days and even shorter, and timeliness is greatly improved.
