Deepwater soft foundation composite foundation and construction method
The invention discloses a deepwater soft foundation composite foundation which comprises a caisson partially sinking below the sea surface and located above the seabed surface; a plurality of caisson bay hollow nodes are reserved in the caisson, are of hollow structures and penetrate through the caisson in the height direction of the caisson; the positions, corresponding to the caisson compartment hollow nodes, of the top of the caisson are each provided with a hoop. A steel pipe pile is coaxially inserted into each caisson compartment hollow node; according to the deep water foundation structure with the pile foundations floating along with the caisson and the construction method, the characteristics of the deep foundation of the pile foundations and the shallow foundation of the caisson are fully utilized, a hectometer water depth cross-sea foundation structure is designed, an efficient construction method with the pile foundations floating along with the caisson is formed, the construction time of a cross-sea bridge under severe sea conditions is shortened, and the construction efficiency is improved. Through initial positioning of the pile foundation, a permanent and temporary structure of foundation structure construction is achieved, and efficient construction of the soft foundation structure with the water depth of 100 meters is achieved.
本发明公开了一种深水软弱地基复合基础，包括：沉箱，其部分沉入海面以下，并位于海床面以上；所述沉箱内预留有多个沉箱隔舱空心节点，其为空心结构，沿着所述沉箱的高度方向贯通；沉箱顶部对应沉箱隔舱空心节点的位置分别设置一个抱箍；每个所述沉箱隔舱空心节点内同轴插入一根钢管桩；本发明的桩基随箱浮运深水基础结构与建造方法，充分利用了桩基础深基础和沉箱浅基础的特点，设计了百米水深跨海基础结构，形成了桩箱同浮的高效施工方法，减少了跨海桥梁在恶劣海况下的施工时间，通过桩基础的初定位实现了基础结构施工的永临结构，实现了百米水深软弱基础结构高效施工。
