Construction method of spatial curved-surface high tower structure

The invention discloses a construction method of a spatial curved-surface high tower structure. The construction method comprises the following steps: I, forming a tower body unit layer by layer by using cast steel components: 1, firstly assembling and splicing a plurality of cast steel components of each layer of the tower body unit by using a special assembly positioning tool and welding, and then welding connecting upright columns of each layer to the inner sides of the corresponding cast steel components to form a multi-layer- tower body unit; and 2, adjusting the curved surface radius and verticality of each layer of the tower body unit and finishing anticorrosion coating; and II, performing hoisting layer by layer from bottom to top and welding the multi-layer tower body unit so as to form a spatial curved-surface high tower. The construction method has the advantages that a high-rise cast steel structure can be arranged conveniently, and the construction safety can be ensured; various types of high tow
