SMALL RIVER PC BRIDGE AND CONSTRUCTION METHOD THEREOF

摘要

PURPOSE: A PC bridge for a small river and a construction method thereof are provided to reduce construction time because a concrete placing work in a construction site is not required. CONSTITUTION: A PC bridge for a small river comprises a bottom base plate for scour prevention, a precast deck(21), precast abutments(22), and a precast slab(23). The bottom base plate is arranged on the bottom of a small river. The precast deck is formed on the top of the bottom base plate and has sheath pipes(211) and tendons(212). The precast abutments are formed on both ends of the precast deck and are connected to the precast deck and the precast slab. Both ends of the precast slab are supported to the top ends of the precast abutments.
