Gradient functional concrete tower column structure and construction method thereof

The invention discloses a gradient functional concrete tower column structure and a construction method thereof. The gradient functional concrete tower column structure comprises a functional layer and a structural layer whose cross sections are arranged in sequence from outside to inside; a functional structure transitional area is arranged between the functional layer and the structural layer; the functional layer and the structural layer are respectively formed by pouring; a concrete tower column structure, which has no macroscopic interface, whose components are in gradient transition andwhich simulates skin, is formed among the functional layer, the structural layer and the functional structure transitional area; the mixed concrete of the functional layer and the structural layer istransported to the field to be poured; during pouring, the top surface of the concrete of the functional layer is always kept to be about 30 cm higher than the concrete of the structural layer; vibrating is carried out during
