The invention discloses a construction method of a double-layer geomembrane composite anti-seepage wall, and aims to provide a construction method which can effectively solve the problems of geomembrane distortion and floating in the construction process of the geomembrane composite anti-seepage wall in the prior art. The construction method of the double-layer geomembrane composite anti-seepage wall can effectively improve the blocking effect of the geomembrane composite anti-seepage wall. The method sequentially comprises the following steps that A, an anti-seepage wall groove is constructed, specifically, TRD equipment is adopted for cutting and stirring in a foundation to form the anti-seepage wall groove; b, a double-layer geomembrane is laid, the geomembrane is lowered in a U shape, the U-shaped geomembrane comprises a left-layer side geomembrane, a right-layer side geomembrane and a bottom geomembrane connecting the bottoms of the left-layer side geomembrane and the right-layer side geomembrane into a
