Seaborne artificial island structure suitable for sludge foundation and construction method
The invention provides a seaborne artificial island structure suitable for a sludge foundation and a construction method. Rock block replacement is carried out on the sludge foundation, a rock block toe pad is arranged on the sludge foundation, a rock block layer is arranged on the upper portion of a rock block replacement layer, a first-stage sea sand filling layer is arranged on the inner side of the rock block layer, and a gravel cushion layer and a first-stage geotechnical cloth are arranged between the rock block layer and the first-stage sea sand filling layer. A sand pipe bag pile is arranged at the position, close to the front section, of the top face of the first-stage sea sand filling layer, trigonum sea sand filling is arranged on the outer side of the sand pipe bag pile, a transition layer is arranged, and a second-stage geotechnical cloth is arranged between the transition layer, the trigonum sea sand filling and the top of the sand pipe bag pile. A rock block protective surface layer is arranged on the outer side of a seaborne artificial island, and a rock block cushion layer is arranged between the transition layer and the rock block protective surface layer. It is not needed to carry out grouting or drainage plate solidification on the sludge foundation during construction, the engineering investment is reduced, the construction period is shortened, and environmental pollution is reduced. Sand pipe bags and the sea sand filling layer are arranged stage by stage according to the filling height, the arrangement is flexible, the fracture surface type is simple,and construction is convenient.
本发明提供了适用于淤泥质地基的海上人工岛结构及施工方法，对淤泥质地基进行块石置换及设置块石护脚，块石置换层上部布置块石层，块石层内侧设置第一级海砂填筑层，块石层与第一级海砂填筑层之间设置碎石垫层及第一级土工布；第一级海砂填筑层顶面的靠近前段位置设置砂管袋堆，砂管袋堆外侧设置三角区海砂填筑，并设置过渡层，过渡层与三角区海砂填筑、砂管袋堆顶部之间设置第二级土工布；在海上人工岛外侧设置块石护面层，过渡层与块石护面层之间设置块石垫层。本发明施工中不需要对淤泥质地基进行灌浆或排水板固结处理，降低工程投资和施工工期，减少环境污染；根据填筑高度分级设置砂管袋及海砂填筑层，布置灵活，断面型式简单、施工方便。
