Title:
CORROSION PREVENTION STRUCTURE OF STEEL PIPE SHEET PILE
Document Type and Number:
Japanese Patent JP2015187364
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a corrosion prevention structure of a steel pipe sheet pile, which eliminates an inclination of an anti-corrosion metal thin plate at a fastening fixed portion of a corrosion prevention cover when preventing the corrosion of the steel pipe sheet pile by double-layer coating corrosion prevention, secures the tightness of the corrosion prevention cover, and can surely exhibit corrosion prevention performance.SOLUTION: The corrosion prevention structure of a steel pipe sheet pile has: a flat part 32 which is formed at a peripheral edge of a body part 31 of an anti-corrosive metal thin plate 3; a fixed plate 41 which is arranged along a rear surface side of the flat part 32, and fixed to a steel pipe sheet pile 1; extension parts of an anti-corrosion layer 21 and of a cushion layer 22 that are laminated between the fixed plate 41 and the flat part 32; a pressing plate 43 which is arranged along a surface of the flat part 32, and extends up to a boundary portion between the flat part 32 and the body part 31; stud bolts 44 which fasten a clearance from the pressing plate 43 up to the fixed plate 41; and a block 46 which is arranged at a side opposite to the body part 11 with the stud bolts 44 interposed between them, and functions as a spacer for restricting the coming of the pressing plate 43 and the fixed plate 41 close to each other.
