Placing manner of canning steel sheet-pile and protective cover null of canning

摘要

PURPOSE:To keep off any damage at the time of driving a heavy corrosionproof part by covering a steel sheet pile provided with a heavy corrosionproof covered layer at a seawater contact part with a protective cover free of attachment or detachment via a buffer member, and driving the steel sheet pile. CONSTITUTION:A heavy corrosionproof covered layer 2 of polyethylene resin or the like is applied to a seawater contact pat on an outer surface of a steel sheet pile 1, thereby constituting an outer surface covered steel sheet pile 1A. Likewise, the heavy corrosionproof covered layer 2 is applied on an inner surface of the steel sheet pile 1, constituting an inner surface covered steel sheet pile 1B as well. Then, each of protective covers 3, 7 is attached to the heavy corrosionproof covered layer of these outer and inner surface covered steel sheet piles 1A, 1B free of attachment or detachment. Each of these protective covers 3, 7 is made up of a plate material 4 of a steel sheet covering the outer surface or inner surface of the steel sheet pile 1 and a cushioning material 5 of rubber or the like covering this plate material 4. These protective covers 3, 7 are attached by an engaged device tightly attached to the steel sheet pile 1 and bolts and nuts. With this constitution, any damage to a heavy corrosionproof part at the time of driving the steel sheet pile is thus preventable.
