Construction method for offshore anchor flexible cofferdam island building
The invention discloses a construction method for offshore anchor flexible cofferdam island building, which comprises the following steps of: constructing a water area foundation: pouring bank protection bearing piles on the water area foundation by adopting an underwater mixing pile engineering ship, so that the bank protection bearing piles and the water area soft foundation form a composite foundation; and an island wall structure is built, specifically, a plurality of first wave-resistant sand bags are stacked on the bank protection bearing piles, sand is blown into the first wave-resistant sand bags, and the sand bag dam bank protection structure which is of a closed-loop structure and is higher than the horizontal plane is formed. Building a land area platform: blowing sand into the whole island until the sand filling amount in the island reaches the elevation to form the land area platform; and then a plastic drainage plate is inserted into the sludge at the bottom of the land area platform for drainage consolidation treatment, so that the artificial island is formed. The shape can be designed according to requirements and does not need to be set into a circle; the original riverbed soil body cannot be greatly damaged; the steel consumption is low; and the later-period dismantling cost is low.
本发明公开了一种用于海上锚锭柔性围堰筑岛的施工方法，包括如下步骤：建设水域地基步骤：采用水下搅拌桩工程船在水域地基上浇筑护岸承重桩，以使护岸承重桩与水域软弱的地基形成复合地基。建设岛壁结构步骤：通过多条第一抗浪砂袋堆垛在护岸承重桩上，并向第一抗浪砂袋内吹砂，以形成闭环结构且高于水平面的砂袋堤坝护岸结构。建设陆域平台步骤：向整个岛内吹砂直至岛内填砂量达到标高，以形成陆域平台；接着用塑料排水板插入陆域平台底部的淤泥处进行排水固结处理，以形成人工岛。其形状可以根据需求设计，而无需必须设置成圆形；其不会对原河床土体造成较大的破坏；其耗费钢材量较低；其后期拆除成本较低。
