CONCRETE BLOCK AND LAYING STRUCTURE USING THE SAME
Document Type and Number:
Japanese Patent JP2018115475
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a concrete block and a laying structure using the same which improve the workability in general concrete blocks, improve the stability of various concrete blocks after construction, further reduce the suction phenomenon of soil on the ground side of the concrete block, promote consolidation effect, and prevent unequal settlement of concrete blocks even if they are served for a long time.SOLUTION: In a concrete block 20 provided with unevenness on the ground plane side, an upper surface groove portion is provided on a surface facing the ground plane of the concrete block 20, and the upper surface groove portion communicates from one side portion of the concrete block 20 to the other side portion.SELECTED DRAWING: Figure 3
