Ecological island for sea reclamation and ecological island building method
The invention relates to an ecological constructed island for sea reclamation. The ecological constructed island comprises a reef bottom cushion layer, a hollowed-out rock-fill layer, an island surface leveling layer and a post-constructed concrete island surface which are sequentially laid from bottom to top. The reef bottom cushion layer is laid at the reef bottom and is formed by laying artificial pebbles into the sea; the hollowed-out rock-fill layer is laid on the reef bottom cushion layer and formed by sea reclamation units which are put into the sea and naturally sink to the bottom to be stacked. Through holes are formed in the middles of the artificial pebbles; the island surface leveling layer is paved on the hollowed-out rock-fill layer, and is cemented and fixed by artificial pebbles through concrete glue, so that gaps of the lower hollowed-out rock-fill layer are filled, and a closed space is provided for pouring and forming of the post-cast concrete island surface; and the post-cast concrete island surface is formed by pouring concrete on the surface of the island surface leveling layer, infiltrating the concrete into the lower island surface leveling layer, and mixing and condensing the concrete with the graded artificial pebbles in the layer to form the sea-reclamation land-building island surface which can be exposed out of the sea surface. The device has both pressure-bearing and ecological functions, the damage of blown sand to the ecological environment of the offshore reef is reduced, and meanwhile, the flexibility of sea reclamation construction is improved.
本发明涉及一种填海造陆用生态筑岛，包括自下而上依次铺设的礁底垫层、镂空堆石层、岛面找平层、后筑混凝土岛面；礁底垫层铺设于礁底，由人造卵石投海铺设而成；镂空堆石层铺设于礁底垫层上，由填海单元投海自然沉底堆积而成；填海单元为人造卵石，中间设有贯通孔；岛面找平层铺设于镂空堆石层上，由人造卵石通过混凝土胶进行胶结固定，实现对下部镂空堆石层空隙的填补，为后筑混凝土岛面浇筑成型提供封闭空间；后筑混凝土岛面采用混凝土浇筑于岛面找平层表面，并渗入下部岛面找平层，与层内级配人造卵石混合凝结，构成可露出于海面的填海造陆岛面。本发明兼备承压与生态功能，减小了吹沙对近岸礁边生态环境的破坏，同时提高了填海施工的灵活性。
