The invention discloses a construction method of a deformable template of a variable cross-section high pier, which comprises the step of installation of each pouring section external mould assembly, wherein each pouring section external mould comprises a plurality of layers of templates which are fixedly superposed together in sequence from bottom to up; each layer of template is formed by the encircling of two transverse templates and two longitudinal templates; the transverse templates are rectangular and have the width equal to that of a pier; the longitudinal templates are isosceles trapezoid and have the altitude equal to that of the transverse templates; and the next step of operation can be conducted according to the existing method after the installation of each pouring section external mould assembly is completed. With the method, a tower crane and a large template are omitted, the cost is saved, the defect that a large device is difficult to transport in an access road in mountain area is overcome,
