The steel concrete synthetic rigid-frame bridge, and that application

摘要

PROBLEM TO BE SOLVED: To provide a structure for efficiently improving river revetments and constructing substructures at narrow sites only by relatively compact lifting equipment without requiring supports or form work in a river, and provide its construction method.;SOLUTION: A revetment structure 60 made of or highly rigid wall bodies such as diaphragm walls and sheet pile bulkheads of steel pipes is used also as the foundation of a bridge or artificial ground. Head parts of the revetment wall bodies are extended upward from a ground surface. Main beams made of H-shape steel or T-shape steel formed by cutting H-shape steel at its web are welded to produce slab bridge panels 70, and the slab bridge panels 70 are mounted to bottom sheet steel 72, which forms a form-cum-strength member at the head parts. Concrete 82 and 84 is pored in such as way as to cover the slab bridge panels 70 and the head parts of the revetment wall bodies 60 to constitute rigid connection at the joint part between the revetment wall bodies 60 and the slab bridge panels 70.;COPYRIGHT: (C)2007,JPO&INPIT
