FIXING CONSTRUCTION FOR UNDERWATER FACILITIES

摘要

A conventional method for fixing an artificial structure to create a seaweed forest artificially in order to relieve efflorescence is to attach the artificial structure directly to a rock, tie a rope, and suspend a weight. However, the conventional method caused problems such as difficulties of underwater operations encountered by divers, the corrosion of ropes, the escaping of ropes by ocean currents, and damage to ropes. In order to solve the problems, the invention provides supports which have a polygonal frame and have a structure with open top and bottom; and a ring-shaped fixing part device which has connection units with one side connected to a main line via a ring formed and with the other side formed with a fixed ball, and has a fixing unit maintaining the fixed state, wherein the connection units and the fixing unit are accommodated to a rail structure arranged on the outer wall of the support so as to fix a longline fixing device in the lower area of water.
