The invention discloses a composite pile structure capable of weakening the influence of negative friction resistance and a construction method, solves the problem that a composite pile structure in the prior art suffers from negative friction resistance, and has the beneficial effect of effectively transferring the negative friction resistance suffered by a pile body, and the specific scheme is as follows: the composite pile structure capable of weakening the influence of the negative friction resistance comprises a cast-in-place pile, the top of the cast-in-place pile is connected with a precast pile, the precast pile is sleeved with an annular first component in the annular direction, at least one first concave part is arranged on the outer surface of the precast pile, each first concave part is provided with a first tooth-shaped track, the first tooth-shaped tracks are arranged in the height direction of the precast pile, and second concave parts are arranged on the inner surface of the first component.
