Revetment structure and revetment construction method

摘要

PROBLEM TO BE SOLVED: To provide a revetment structure and a revetment construction method capable of suppressing horizontal movement of the revetment structure and ensuring stable water impermeability. SOLUTION: In a bank protection structure, a space is provided between a water-impervious base on the sea floor in which a groove having a bottom along a horizontal plane and a side wall perpendicular to the horizontal plane is formed on the upper surface, and a side wall of the groove at the bottom of the groove. It is arranged so as to fill the gap between the bank protection structure arranged in an open state, the impermeable layer arranged so as to fill the space between the bank protection structure and the side wall of the groove, and the space between the bank protection structure and the side wall of the groove. , Has a load transfer material that can transmit the horizontal force from the bank protection structure to the side wall as a shear force, and the thickness in the vertical direction is set so that it does not buckle in the vertical direction when the horizontal force is transmitted to the side wall. It is provided with a load transfer layer. [Selection diagram] Fig. 1
