SEAWALL BLOCK AND SEAWALL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a seawall block that can improve workability when constructing a seawall structure.SOLUTION: A seawall block 10 is configured as follows: three protrusions 11a, 11b and 11c are provided at intervals in the left and right direction in a lower surface of a body plate part 11; each of the protrusion 11a, 11b and 11c is insertable on the upper surface of the body plate part 11, and three grooves 11d, 11e and 11f with a front end closed and a rear end opened are provided at intervals in the left and right direction, respectively; the body plate part 11 of the seawall block 10 of the upper stage side and the lower surface of two overhanging plate parts 12 are brought into contact with the body plate part 11 of the seawall block 10 of the lower stage side and the upper surface of the two overhanging plate parts 12, respectively, when vertically stacking the seawall blocks 10; and three protrusions 11a, 11b and 11c of the seawall block 10 of the upper stage side are inserted in three grooves of the seawall block 10 of the lower stage side, respectively, while each forward direction movement is blocked.SELECTED DRAWING: Figure 1
