摘要
The present invention relates to a structure for restraining local scour around a pier of a bridge constructed over a river or over the sea and, more particularly, to a stone filled strand net (30) for local scour prevention which is formed in such a manner that a reticulate body is filled with filling stones (15), such as gravel, boulders, or crushed stones, and is sutured, and a construction method of a pier scour prevention hole using the same. The reticulate body is formed with a strand net which is woven by a strand (10) connected to a porous plate (20) in which a plurality of through holes (21) is formed, and the reticulate body is filled with the filling stones (15) and is sutured to complete the stone filled strand net (30). The completed stone filled strand net (30) is seated on a river bed around a pier (40) to resist scour. The present invention can remarkably enhance tensile strength and wear resisting quality of the reticulate body for the stone filled strand net (30), thereby increasing structural stability and durability of the pier scour prevention hole which is formed by masonry construction of the stone filled strand nets (30).
