Falling stone prevention fence of dual connection structure for improved safety

摘要

The present invention relates to a rockfall prevention fence of a dual connection structure with improved safety. The present invention can provide the rockfall prevention fence with sharply improved safety, since a connection state of a wire rope can be maintained even when a tension spring is separated, by that the wire rope (20) slides to be moved until an adaptor (21) of one end of the wire rope (20) is latched at a first sliding hole (631) of a joint (60) and at the same time a cap (51) of one end of an auxiliary rope (50) is latched at a second sliding hole (61) in case connection between one side of a pillar (10) and one end of the wire rope (20) is separated, on the basis of the dual connection structure of multiple wire ropes (20) arranged horizontally at multiple pillars (10) and multiple auxiliary ropes (50) which straightly overlap with two wire ropes extended horizontally from both sides of the pillar.
