Novel pile foundation jacket foundation grouting connection section structure and construction method thereof
The invention discloses a pile foundation jacket foundation grouting connection section structure. The structure comprises a steel pipe pile, a mud storage barrel with the top end closed is arranged in the steel pipe pile, an extension plate is arranged at the bottom end of the mud storage barrel, the tail end of the extension plate is connected with the inner wall of the steel pipe pile, and themud storage barrel, the extension plate and the inner wall of the steel pipe pile form an annular grouting area; and a main guide pipe insertion section is inserted into the annular grouting area, andgrouting materials are poured between the main guide pipe insertion section and the steel pipe pile. According to the structure, soil in the pile is partially guided out of the pile and partially stored in the pile, no soil exists in the grouting connection section and is isolated from the interior of the steel pipe pile, the problem that the grouting insertion section cannot be arranged below the mud surface is effectively solved on the premise that the structural construction requirement of the grouting connection section and the structural safety of a pile foundation jacket are met, a series of problems that mud is sucked, steel pipe pile cantilevers are too long, the sealing performance of the lower end of the grouting connection section cannot be guaranteed, and steel pipes are wasted are solved, and the foundation structure safety, construction convenience and structure optimization design are improved.
一种桩基导管架基础灌浆连接段结构，包括钢管桩，所述钢管桩内设置有顶端封闭的储泥筒，所述储泥筒的底端设置有外延板，所述外延板的末端与钢管桩内壁相连，所述储泥筒、外延板与钢管桩内壁构成环形灌浆区，所述环形灌浆区内插设有主导管插入段，所述主导管插入段与钢管桩之间灌注有灌浆料。本发明通过将桩内泥土部分导至桩外、部分储藏在桩内，并使灌浆连接段内无泥土且与钢管桩内部隔绝，在满足灌浆连接段结构构造要求及桩基导管架结构安全的前提下，有效解决灌浆插入段无法设置在泥面以下问题，进而避免吸泥、钢管桩悬臂多过长、灌浆连接段下端无法保证密封性、钢管浪费等一系列问题，提高基础结构安全性、施工便利性和结构优化设计。
