THE ARCH BRIDGE AND THE CONSTRUCTION METHOD IMPROVING WATER FLOWING

摘要

PURPOSE: An arch bridge improving the water flow and a construction method thereof are provided to minimize the horizontal reaction actuating on an arch angle block comprising the arch bridge. CONSTITUTION: A mold stands on foundation supported in a bedrock layer(S21). A steel reinforcement is arranged to be connected to the foundation(S22). An arched board in which the width gradually becomes narrow is mounted. Side walls are installed at the both sides of the arched board(S2). Soil is poured on the arched board(S3). The arched board in which the soil is poured is paved. A natural rock pattern is formed on the outer surface of the sidewall(S4).
