SCOUR PREVENTING CONSTRUCTION AROUND PILE-SHAPED BODY, AND CONSTRUCTION METHOD OF SCOUR PREVENTING CONSTRUCTION AROUND PILE-SHAPED BODY
To provide a scour preventing construction around a pile-shaped body and a construction method of a scour preventing construction around a pile-shaped body capable of easily managing a top end height without the necessity of shaping and not damaging a foundation structure and an incidental installed object.SOLUTION: A positioning cradle 13 is installed on a water bottom 1 in a peripheral edge portion of an installation position of an asphalt mat 3, and then asphalt mats 3-1-1 and 3-1-2 are lifted down by using a hanging metal fitting 15, to lay them on the water bottom 1. In the same procedure, the remaining asphalt mats 3-2, 3-3,... are sequentially laid on the water bottom 1. The asphalt mat 3 is laid so as to provide an overlapping portion. Then, a foundation pile 9 is inserted into an installation hole 11 formed in a center of the asphalt mat 3, and the foundation pile 9 is installed on the water bottom 1. After that, a ring-shaped rectangular hat 5 is installed so as to cover a gap 12 between the foundation pile 9 and the asphalt mat 3, and a weight 7 is installed on the asphalt mat 3, to complete scour preventing construction 2.SELECTED DRAWING: Figure 1
【課題】整形が不要で天端高さを容易に管理することができ、基礎構造物や付帯設置物を損傷させることがない杭状体周辺の洗掘防止工および杭状体周辺の洗掘防止工の施工方法を提供すること。【解決手段】アスファルトマット３の設置位置の周縁部の水底１に位置決め用の架台１３を設置した後、吊金具１５を用いてアスファルトマット３−１−１、３−１−２を吊り降ろし、水底１に敷設する。同様の手順で、残りのアスファルトマット３−２、３−３…を水底１に順次敷設する。アスファルトマット３は、重なり部分を設けて敷設される。次に、アスファルトマット３の中央に形成された設置孔１１に基礎杭９を挿入し、基礎杭９を水底１に設置する。その後、基礎杭９とアスファルトマット３との隙間１２を覆うようにリング矩形ハット５を設置し、アスファルトマット３上に錘７を設置して、洗掘防止工２を完成する。【選択図】図１
