The invention relates to a construction technology, and particularly discloses a construction technology for precise alignment in the construction process that a steel box girder is provided with a consolidation pier. The construction technology comprises the steps that 1, in the installation construction process of the steel box girder, before the steel box girder on lifting beam section is connected with the consolidation pier, an embedding sleeve is fixed to the lower side of a bottom plate of the steel box girder; 2, an embedded sleeve is arranged over the consolidation pier, the positions, in the embedded sleeve, of the intersection areas of each pair of longitudinal and transverse square pipes are aligned to steel bar reserved gaps in the lower side of the steel box girder; 3, the upper ends of finished deformed steel bars on the consolidation pier are arranged in the intersection areas of each pair of longitudinal and transverse square pipes; 4, when the steel box girder on lifting beam section is connected with the consolidation pier, the embedded sleeve is matched with the interior of the embedding sleeve, the finished deformed steel bars are inserted into the steel bar reserved gaps in the lower side of the steel box girder. The problems are solved that in the construction process that the finished deformed steel bars are aligned to the reserved holes in the bottom plate of the box girder at a high altitude, hidden safety hazards to construction operators exist, and the operation difficulty during the manual operation is high.
