HALF ASSEMBLY-TYPED CONSTRUCTION SYSTEM AND METHOD OF COMMON DUCT

摘要

A construction structure and method of a semi-prefabricated common duct is provided to minimize excavation work for constructing a common duct and improve workability. A construction structure of a semi-prefabricated common duct comprises a base(10), and steel assembly wall forms(20) installed at two sides of the base(10). The steel assembly wall form(20) comprises a wall form(20a) to which wall steels(20b) are assembled. A steel assembly slab form(30) is installed on the wall form(20a), and comprises a slab form(30a) to which slab steels(30b) are partially or entirely assembled. A concrete(50) is cast in the steel assembly wall form(20) and on the steel assembly slab form(30). A reinforcing support(40) reinforces and supports the steel assembly wall form(20) until the concrete(50) is cured.
