Construction method of subway side wall tripod single-side aluminum mold

The invention discloses a construction method of a subway side wall tripod single-side aluminum mold, which comprises the following steps of: 1, constructing a bottom plate (4) and a reverse side wall (5), and installing a haunch angle template (1), so that a haunch angle structure (8) is formed between the reverse side wall (5) and the bottom plate (4); 2, binding reinforcing steel bars of a subway side wall (7); 3, assembling a formwork support system; 4, adjusting and reinforcing the formwork support system; 5, pouring the subway side wall (7) with concrete; 6, after pouring of the subway side wall (7) reaches the design strength, removing the formwork support system, and removing the formwork support system to the next construction section through universal wheels; and 7, repeating the step 1 to the step 6 until construction of the whole subway side wall (7) is completed. By means of the combined structure of the aluminum formworks and the triangular formwork supports of the aluminum formworks, the side w
