Abstract: Aimed at the problem that assembly production and construction of infrastructure which is easy to be ignored during the process of building industrialization, combined with the need for industrial development, a kind of prefabricated foundation for substation fence which can replace traditional cast-in-place strip foundation is designed. Its basic component type has two main kinds such as non corner and wide sleeper corner. Meanwhile, whole prefabricated foundation for substation fence is designed optimally and an innovation that the grid form of floor reinforcement at the corner is adopted at double bi-directional diagonal connection is raised. Finally, please briefly analyse economic benefits of prefabricated foundation for substation fence in use.
