The cofferdam-free hydraulic reclamation construction method comprises the steps that an anti-fouling screen is arranged on the periphery of an island building area, and a north sand dike, an east sand dike, a south sand dike and a west sand dike are formed in the island building area through hydraulic reclamation; the top width of the north sand dike is widened through hydraulic reclamation on the inner side of the north sand dike; sand quilts are laid on the inner side of the east sand dam, the inner side of the Nansha dam and the inner side of the west sand dam for the first time; the inner side of an area defined by the east sand dike sand quilt, the Nansha dike sand quilt, the west sand dike sand quilt and the north sand dike which are laid for the first time is subjected to centralized hydraulic reclamation; sand quilts are laid on the top of the east sand dike sand quilt, the top of the Nansha sand dike sand quilt and the top of the west sand dike sand quilt for the second time, and the sand quilts laid for the first time and the sand quilts laid for the second time jointly form a sand quilt cofferdam; intensively blowing and filling the inner side of the sand quilt cofferdam; paving geotechnical cloth and surface protection block stones, throwing and filling cushion layer stones, throwing and filling bottom protection block stones, and mounting fence plates. The construction on the inner side of the sand dike can be prevented from polluting the open sea, a storage yard can be provided for sand nearby, and meanwhile sand quilt filling construction is facilitated.
本发明公开了一种人工岛无围堰吹填施工方法，包括：在造岛区外围设置防污屏，在造岛区吹填形成北沙堤、东沙堤、南沙堤和西沙堤；在北沙堤内侧吹填加宽北沙堤顶部宽度；在东沙堤内侧、南沙堤内侧、西沙堤内侧第一次铺设砂被；在第一次铺设的东沙堤砂被、南沙堤砂被、西沙堤砂被与北沙堤围成的区域内侧集中吹填；在东沙堤砂被顶部、南沙堤砂被顶部、西沙堤砂被顶部第二次铺设砂被，第一次铺设的砂被与第二次铺设的砂被共同形成砂被围堰；在砂被围堰内侧集中吹填；铺设土工布、护面块石、抛填垫层石料、抛填护底块石、安装栅栏板。本发明既能防止沙堤内侧的施工污染外海，又能给沙料就近提供堆场，同时还方便充灌砂被施工。
