ものであった。In recent years, rock fishing has become explosively popular as an easy and healthy form of recreation, and artificial rock fishing spots have been set up near cities where fishing spots are scarce. However, the structure of conventional artificial rock fishing spots is mainly made of iron pipes or steel frames. Examples include piers for sea fishing parks, etc. In either case, the appearance does not match the natural landscape, and in addition, fishing from a far distance from the water surface, and fishing from the shore while being in direct contact with seawater etc. The structure made it impossible to enjoy play.

。Figure 5 shows an example of installing several artificial rock reefs 5 adjacent to a conventional sea fishing park pier to create an artificial fish reef, or partially exposing a portion above the water surface to create a small artificial rock fishing spot. . In this case, each artificial rock reef 5 is designed so that it is always exposed above the water surface after installation, or so that it is submerged underwater at high tide and a part of it is exposed above the water surface at low tide, or always. It is installed appropriately so that it is submerged under the water surface.

磯遊びを楽しむことができる。(Effects of the Invention) By installing the artificial rock reef of the present invention in water using the installation method described above, it is possible to artificially and easily create a suitable appearance and environment similar to that of a natural reef. To safely and easily perform rock fishing, playing on a rock, etc. on a part of a pseudo-reef exposed above the water surface, while directly coming into contact with nature such as seawater. Further, by installing fiber-reinforced mortar-sprayed fiber-reinforced mortar layers on the artificial reef, it is possible to enjoy fishing and playing on the shore even at night by arranging optical fiber illumination devices at appropriate locations on the layer.
