Traditionally, river embankments built using natural stones are filled with eels, catfish,
Fish such as crabs, shrimp, and small fish could live here, and a natural ecology was nurtured here, giving humans a sense of the natural environment and its richness. However, in recent years, with the development of construction using concrete blocks, the situation has completely changed, and fish can no longer live in the embankments, and the favorable natural environment of rivers appears to be completely disappearing.

Next, an embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, the interlock block according to the embodiment mainly includes a mating end portion 2 having a mirror surface 1, and a retaining portion formed integrally with this mating end portion and having a butt end 4 at the rear end. It is composed of 3. In the block joint surface 5 of the mating end portion 2, a groove 6 having a substantially semicircular cross section is formed over the entire circumference of the block joint surface 5. Further, from the mirror surface 1 to the groove 6
Grooves 7, 8 having semicircular and quarter-circular cross sections are formed in the block joint surface 5 of the joint end portion 2, leading to the grooves 7 and 8. This groove 7 is formed at a position apart from both ends of the long side a of the mirror surface 1 by the length of the short side b.
are formed at the corners of both ends of the long side a' opposite to the long side a.

る。 Next, a method of constructing the interstitial block constructed as described above will be explained. In the case of the valley pile construction method, first, as shown in Figs. 5 and 6, grooves 7 shown in Fig.
Blocks A with A are arranged horizontally in a row at a 45 degree inclination. Next, a block B having the groove 7B shown in FIG. 4 is inserted into the valley of the block A.
Tilt them 45 degrees in the opposite direction and line them up horizontally. After that, stack blocks A and B repeatedly, and then stack normal seawall blocks on top. When the blocks A and B are assembled, the semicircular grooves 6 of the adjacent blocks A and B are brought together to form a habitat passage for fish inside the retaining wall. At the same time, the semicircular grooves 7 and the quarter-circular grooves 8 of the adjacent blocks A and B are brought together to form an entry and exit passage for fish. Therefore, when the grooves 7 and 8 are located below the water level 12 of the river, fish can freely come in and out through the grooves 7 and 8 and live there. The above-mentioned interstitial block can also be constructed using the laying method.

As explained above, in the present invention, a semicircular groove extending in the circumferential direction of the mating end, a semicircular groove and a quarter-circular groove leading from the rectangular mirror surface to the groove, A semicircular groove is formed on one long side of the mirror surface, and a quarter circular groove is formed on both corners between the other long side and short side. Since the semicircular groove is located the length of the short side from the end of the long side, the cross-sectional area can be increased without increasing the external dimensions of the block or impairing its strength or function. This has the effect of creating a large and long habitat passageway and entrance/exit passageway. Furthermore,
The grooves of the fish nest block of this invention are semicircular or 4 grooves.
Since it is in the shape of a quarter circle, it is easy to remove the formwork, and it is easy to manufacture, and it can be constructed using the same method as ordinary blocks.
