Construction method of assembled girder crane foundation for high-speed railway box girder field

The invention discloses a construction method of an assembled girder crane foundation for a high-speed railway box girder field, and belongs to the technical field of high-speed railway box girder prefabrication. The method comprises the steps that firstly, waterproof protection construction is carried out on an existing roadbed, and then the assembled girder crane foundation is hoisted on the roadbed. The assembled girder crane foundation comprises a plurality of cuboid girder crane foundation single bodies, the plurality of girder crane foundation single bodies are spliced into a column, andthe front end faces and the rear end faces of every two adjacent girder crane foundation single bodies are fixedly connected through connecting steel plates and fixing bolts. The method is green andenvironment-friendly, the construction process is simple, universality is high, the popularization and practical value is high, girder crane foundation concrete components can be recycled, energy consumption is reduced, and th
