Summary:The invention discloses a fabricated multi-layer integral mounting method for an inner support of a steel sheet pile cofferdam of a deepwater foundation. The fabricated multi-layer integral inner support is prefabricated on a backfield, an inner support lowering temporary platform, a crossed support reinforcing structure and an inner support hanging system are mounted at the top end of a pluralityof bored pile steel pile casings in the cofferdam, and then the fabricated multi-layer integral inner support is hoisted on the inner support lowering temporary platform and lowered to be mounted a designed-elevation position through the inner support hanging system. According to the fabricated multi-layer integral mounting method for the inner support of the steel sheet pile cofferdam of the deepwater foundation, the inner support is prefabricated into the fabricated multi-layer integral inner support and is then lowered to be positioned, so that the field construction efficiency is greatlyimproved, and the field co
