Four legs 3, 3, 3, 3, 4, 4, 4, 4 respectively
is installed protrudingly. Each leg 3, 4 surrounds the hole 2 and is spaced at 90° to the center. Each of the legs 3 and 4 has the same height and has a substantially truncated pyramid shape, with one side continuing to the side surface of the substrate 1 to form a vertical surface 1a, and the other side facing the square hole 2. An inclined surface 1b is formed.
表裏に形成される傾斜面１ｂ，１ｂのなす角α

減少に役立つことになる。 In Fig. 15, blocks were laid as an offshore embankment, and block group B was laid in a layered manner. As a method of laying, as shown in FIG. 16, it is preferable to stack other blocks A' so as to straddle the legs 3, 3 of adjacent blocks A and A.
When blocks are stacked as shown in Figure 16,
Gap 5 between the lower block and the upper block
is formed, and this gap 5 serves to reduce the lift force acting on the block.

In cooperation with the central hole, the lifting force acting on the block is reduced as much as possible, and it functions as a stable foot protection block.In addition, the blocks can be freely changed direction within the octagonal area and laid against each other. This can improve work efficiency, and when used as a wave-dissipating block, it can be used to block waves or currents,
The weight of the legs can be varied in relation to the direction of the river flow by rotating the blocks horizontally, or by stacking blocks to increase or decrease water resistance. Regardless of the type of block, it is possible to adjust wave dissipation or water flow, etc.
