Offshore electrical platform pile-sleeve foundation structure with anti-caisson structure
The invention provides an offshore electrical platform pile-sleeve foundation structure with an anti-caisson structure. The offshore electrical platform pile-sleeve foundation structure comprises a jacket and a sleeve, an anti-caisson is arranged at the bottoms of the jacket and the sleeve, a grouting system is arranged between the jacket and the sleeve, a grouting connecting section is arranged on the sleeve, a steel bar reinforcing structure is arranged at the bottom of the grouting connecting section and in the sleeve, and a passive grouting separator is arranged below the steel bar reinforcing structure; and the anti-caisson comprises a top plate on the top layer, a panel is welded to the lower portion of the top plate, a plurality of apron boards are welded to the periphery of the topplate, and a plurality of rib plates are arranged on the inner sides of the apron boards at intervals. According to the offshore electrical platform pile-sleeve foundation structure, the stability ofthe offshore electrical platform foundation during bottom setting can be effectively improved, the bearing capacity of the grouting connecting section and a pile foundation of the platform structurein the bearing strength limit state is guaranteed, and a new thought is provided for offshore electrical platform design.
本发明提供了一种具有防沉箱结构的海上电气平台桩‑套筒基础结构，包括导管架和套筒，导管架和套筒的底部设置防沉箱，导管架和套筒之间布置灌浆系统，套筒上设置灌浆连接段，所述套筒内部在灌浆连接段的底部设置钢筋增强结构，钢筋增强结构下方设置被动式灌浆分隔器，所述防沉箱包括顶层的顶板，顶板的下部焊接面板，顶板的四周焊设多个裙板，裙板内侧间隔布置多个筋板；本发明可有效提高海上电气平台基础坐底时的稳定性，保障平台结构在承载强度极限状态下灌浆连接段及桩基的承载能力，为海上电气平台设计提供新的思路。
