ROAD CONSTRUCTION METHOD NEAR BRIDGE ABUTMENT

摘要

PROBLEM TO BE SOLVED: To provide a road construction method near a bridge abutment capable of absorbing an angle of rotation due to the deflection of a bridge girder with a square hooked connector installed to a joining portion between a floor slab at the bridge beam side and a floor slab at the earthwork side. SOLUTION: A square hooked connector 40 is installed in the joining portion between an extended floor slab 17 at the side of a bridge beam 1 and an auxiliary floor slab 23a at the earthwork 7 side; and plural movement-restricting connectors 30 etc. are installed in the auxiliary floor slabs 23 etc. at the earthwork side thereby permitting the expansion and contraction of the structure.
