Construction method of steel box core concrete combined cable bent tower

The invention belongs to the technical field of cable bent tower construction, and particularly relates to a steel box core concrete combined cable bent tower construction method which comprises the following steps: step 1, mounting a combination section positioning bracket; step 2, mounting reinforcing steel bars of the combination section; step 3, hoisting, adjusting and positioning a steel tower reference section; fourthly, concrete pouring is conducted on the combination section; and 5, constructing the upper steel tower. According to the construction method of the steel box core concrete combined cable bent tower, by arranging the first step to the fifth step, when the steel box core concrete combined cable bent tower is constructed, a steel box is subjected to segmented machining in advance, then segmented hoisting construction is conducted, and the hoisting weight of a steel structure is reduced; and the hoisting and assembling steel tower sections and the installed and positioned fixed steel tower sec
