REINFORCEMENT STRUCTURE OF EXISTING BREAKWATER, REINFORCEMENT METHOD OF EXISTING BREAKWATER, AND REINFORCEMENT BODY

摘要

PROBLEM TO BE SOLVED: To provide a simple reinforcement structure of an existing breakwater, facilitating construction, and having high reinforcement effect.SOLUTION: A breakwater 1 is constructed by disposing caissons 11 side by side on a mound 2. Reinforcement bodies 3, each of which is formed by providing a friction increasing mat 32 under the bottom surface of a block body 31, are installed on both end sides of the caissons 11 in the longitudinal direction of the breakwater adjacent to each other on the mound 2 in a land side and an ocean side of the breakwater 1. Thereby, resistance force against sliding and overturn of the breakwater 1 caused by waves toward the land and the ocean is increased, and also scouring of the mound 2 by waves overflowing the breakwater 1 is prevented.
