[Objective] Aiming to solve the problem in construction of foundation engineering in the field of water conservancy, water conservation and civil construction engineering that the steel cage processing platform has the disadvantages of high cost, inconvenient use, large material waste, poor standard and poor processing quality, based on the design idea of "systematization and modularization", a steel cage fabrication platform is designed.[Methods] The machining platform mainly consisted of a fixed support module and a fixed shaft module. The fixed frame module was composed of a pair of fixed supports and the fixed shaft module was composed of a high cage module, a middle cage module and a low cage module. The internal fixing axle module was connected with the external fixing shaft module through the inner rolling bearing. The outer surface of the outer fixed shaft module was provided with a plurality of main rib inserts. The main reinforcement plate was provided with a transverse main reinforcement groove and a longitudinal reinforcing hoop or a supporting hoop slot.[Results] The design could solve the problem that the dimension of reinforcing steel cage of various pile foundations was not universal, and to solve the problems of steel cage processing was not unified, not standard and the steel cage could only be used in a project once. This design could not only make the steel cage more conform to the standard requirements, but also could prevented contamination of the cage caused by soil and oil contamination in the production process. It could greatly improve the production and construction efficiency, and could save costs and protect the environment.[Conclusion] The improvement design of the steel bar cage processing platform is of great importance to the sustainable development of equipment and materials in different types of infrastructure projects. The design can further realize the cyclic application of building materials.
