Polygonal gravity type foundation of offshore booster station
The invention provides a polygonal gravity type foundation of an offshore booster station. The polygonal gravity type foundation comprises a supporting table, at least two transition columns and polygonal concrete cavity piers. The bottom of the supporting table is fixedly connected with the top of a transition column. The bottom of the transition column is fixedly connected with the top of the polygonal concrete cavity pier; the transition column comprises a steel circular pipe and a prestressed concrete circular pipe which are connected up and down; the top of the polygonal concrete cavity pier is provided with a sand injection hole and a lifting lug. The foundation is suitable for rock-based geology with deep and shallow covering layer burying, compared with a traditional jacket steel structure foundation of an offshore booster station, rock-socketed is not needed under the rock-based geology condition, and the foundation is mostly made of concrete materials, so that the structure manufacturing cost can be reduced; and after the polygonal gravity type foundation is manufactured and assembled on a wharf or a dock, a special ship is adopted for floating transportation and wet dragging transportation, large hoisting equipment is not needed, offshore assembly is not needed, offshore operation procedures are greatly reduced, the construction cost is low, and application and popularization are facilitated.
本发明提供一种海上升压站的多边形重力式基础，包括支撑台、至少两根过渡柱以及多边形混凝土空腔墩；所述支撑台的底部与过渡柱的顶部固定连接；所述过渡柱的底部与多边形混凝土空腔墩的顶部固定连接；所述过渡柱包括上下连接的钢圆管和预应力混凝土圆管；所述多边形混凝土空腔墩的顶部设置有注砂孔和吊耳。本发明适用于覆盖层埋深浅的岩基地质，相较于海上升压站传统导管架钢结构基础，在岩基地质条件无需嵌岩，且该基础大部分采用混凝土材料可以降低结构造价；并且该多边形重力式基础在码头或船坞制造拼装完成后，采用专有船舶浮运湿拖运输，无需大型起吊装备，无需海上拼装，大幅减少海上作业工序，施工费用低，有利于推广应用。
