CORROSIONPROOF STRUCTURE AND CORROSIONPROOF METHOD OF HEAVY CORROSIONPROOF STEEL SHEET-PILE JOINT SECTION

摘要

PROBLEM TO BE SOLVED: To provide the corrosionproof structure of heavy corrosionproof steel sheet-pile joints in which the mutual joint sections of extremely heavy corrosionproof steel sheet-piles exposed to the flying of the tide and an ebb and a flow for a prolonged term are corrosion-protected firmly and simply, including sections where heavy corrosionproof films are not formed, while preventing the peelng of the corrosionproof films. SOLUTION: The corrosionproof structure 1 of the heavy corrosionproof steel sheet-pile joint sections has a structure in which joint regions are shielded and fixed by a protective cover 10 to joints 21a and 22a for the first and second heavy corrosionproof steel sheet piles 21A and 22B. The protective cover 10 is constituted integrally and elastically in an approximately L-shaped cross section from an inserting plate section 11 and a shielding plate section 12. A pushing adjusting member 30 is installed to the shielding plate section 12 for the protective cover 10, and the member 30 is constituted so as to adjust a space between the steel sheet pile 21A and the shielding plate section 12 under the state in which the steel sheet pile 21A is pushed. The joint regions are filled with an underwater curable anticorrosive. COPYRIGHT: (C)2004,JPO
