CORROSION-PROOF COVERING BODY FOR STEEL SHEET PILE, AND CORROSION-PROOF STRUCTURE FOR STEEL SHEET PILE

摘要

PROBLEM TO BE SOLVED: To provide a corrosion-proof covering body for a steel sheet pile, and a corrosion-proof structure for the steel sheet pile, which secures adhesion to the steel sheet pile to improve corrosion-proof durability by following the deformation of the steel sheet pile and suppressing deformation caused by the fastening force of a fixing means while securing quality such as super-long-term durability and excellent impact resistance by coating a resin corrosion-proof layer with a high corrosion resistant metal plate.;SOLUTION: Recesses 331 are formed in the high corrosion resistant metal plate to increase flexural rigidity in the width direction of a linear part 34 and to suppress the deformation of the linear part 34 by the rigidity increasing effect. A close contact state between the steel sheet pile and a petrolatum sheet 31 of the corrosion-proof covering body 3 can thereby be maintained, suppressing the entry of water, oxygen, corrosive ion, etc. between them. The degradation and outflow of the petrolatum sheet 31 is thereby prevented to improve corrosion-proof durability.;COPYRIGHT: (C)2011,JPO&INPIT
