The invention provides a single stand column flower-shaped tower and a construction method thereof. The lower-shaped tower comprises a tower body, a tower crown connected to the top of the tower body and an overhauling structure connected to the tower crown. The tower crown comprises a first truss disc, a second truss disc and a third truss disc which are connected with the tower body in a sleeving mode. The first truss disc, the second truss disc and the third truss disc are sequentially arranged in a horizontal and spaced mode from bottom to top. A set of first rigid supports are connected in a radial and annular mode in the direction from the first truss disc to the second truss disc, a first inhaul cable is connected between opposite angles of every two adjacent first rigid supports in a shear-fork shape, and a set of second rigid supports are annularly arranged in a vertical plane between the second truss disc and the third truss disc; and a second inhaul cable is connected between opposite angles of every two adjacent second rigid supports in the shear-fork shape. The single stand column flower-shaped tower is simple and stable in structure, the single stand column top truss stress puzzle is greatly solved, and overall stability is achieved; and construction of the single stand column flower-shaped tower is more convenient and faster, and the entirety has more plasticity while it is guaranteed that a tower crown structure is stable in stress.
