Artificial fish reef, sinking, fishway, and seawall member using waterside installation members

摘要

PPROBLEM TO BE SOLVED: To provide a means, whereby when a plurality of seashore installation members are connected to one another to make an artificial reef, a submerged mattress, a fish path, or a shore protection member, the connecting of the seashore installation members can be performed more firmly, at a higher working efficiency, and the members can be installed more stably, despite the influence of forces of, for example, streams or waves. PSOLUTION: The artificial reef 14 includes a seashore installed member 1 composed of a plurality of natural stones 3 with a through-hole 2 and a chain 4, that is inserted into the through-holes 2 of the natural stones 3 to unite them together; shackles 16 attached to both ends of the chain 4 of the member 1 and each composed of a substantially a U-shaped body 19 with insertion holes 15 and a connecting rod 21, that crosses the opening 20 of the body 19 to connect both ends; and anchor bolts 18, inserted into the insertion holes 25 of the shackles 16 and driven into the ground 17 on a seashore.
