Document Type and Number:
Japanese Patent JP6808211
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a construction method of a reinforcement structure for an erosion control dam that enhances abrasion resistance and impact resistance of a top edge surface of the erosion control dam and is compatible with unmanned construction.SOLUTION: A reinforcement structure 3 includes a first steel member 61 and first elastic members 51a, 51b that form a dam-like body, the first steel member being installed on a top edge surface 37 of an erosion control dam 5 and the first elastic members surrounding a side surface of the first steel member 61. The reinforcement structure further includes concrete 91 placed on the top edge surface 37, and a protection member 8 installed on the concrete 91. The protection member 8 comprises a second steel member 15 made of an L-shaped member, and a second elastic member 52 fixed on the second steel member 15. The protection member 8 is installed by descending onto the first steel member 61 and the concrete 91 before curing, from a position indicated by a two-dot chain line. The configuration enables installation of the protection member 8 using a helicopter and the like, at the same time enhancing safety and reliability of construction work for the reinforcement structure 3, and making the construction method compatible with unmanned construction.SELECTED DRAWING: Figure 9
