A method for manufacturing a large-scale balance weight of a steel sheet pile ship lift, which simplifies the processing flow of the large-scale balance weight. The method first cuts a continuous casting steel blank into single pieces of steel sheet pile with grooves, and measures and marks the steel sheet pile. Then, two groups of steel sheet pile are assembled together by processing and pre-installing gap pads. After the preliminary assembly is completed, the balance weight is marked again, and then the locking bolt holes, pin shaft holes and lifting lug holes are drilled and processed, and the holes are counterbored. The next step is to cut and install the edge plates at the top and bottom of the grooves. The trial lifting is performed and the lifting shaft hole reinforcing plates are pre-installed to ensure the stability of the structure. The stop seat plates are further processed and installed to provide protection for the final stability. Finally, the overall performance of the balance weight is verified by the second trial lifting, and the remaining edge plates are pre-installed. The present application can realize efficient processing of large-scale steel sheet pile balance weight by using conventional general equipment.
