The invention provides a steel centering machining device and a construction method. Mold supports are arranged according to the radian required by the design, steel bars are bent to a first clamping groove of the next mold support through a clamping groove angle by means of a first clamping groove, the operation is repeated, and the steel bars are bent to a first clamping groove of the last mold support; the steel bars slide to a second clamping groove along the cambered surface, if the steel bars just enter the second clamping groove, it shows that the angle meets the design requirement, and the steel bars slide into a third clamping groove through the radian; and the steel bars are triangularly welded through braces, so that the purpose of increasing the bearing capacity is achieved, the safety performance of a centering is improved to a certain extent, the safety performance of diversion tunnel supporting is improved, and the safety of engineering construction is guaranteed. Manpower is reduced, material
