Pile-first method jacket foundation in-pile slurry leakage prevention construction system and construction method
The invention discloses a pile-first method jacket foundation in-pile slurry leakage prevention construction system and a construction method. The construction system comprises a steel pipe pile and a jacket, the jacket is inserted into the steel pipe pile, and an annular grouting space for pouring grouting materials is formed between the steel pipe pile and the jacket; and a gravel filling layer is further filled above the mud surface elevation in the steel pipe pile. The construction method comprises the steps that the steel pipe pile is piled to the designed elevation; the filling amount of gravels or gallets in the steel pipe pile is determined; the jacket is mounted; the jacket is leveled and locked; and the grouting materials are poured into the annular grouting space. Aiming at the construction of a pile-first method jacket foundation, in particular to a jacket structure of which a grouting connection section is above the mud surface elevation and the pile diameter is relatively large, the pile-first method jacket foundation in-pile slurry leakage prevention construction system has the characteristics of simple construction method, low equipment requirement, saving of offshore construction time, reduction of grouting material loss rate and construction cost and the like, and a powerful guarantee is provided for ensuring the connecting quality of the jacket and the steel pipe pile.
本申请公开了一种先桩法导管架基础桩内防漏浆施工系统及施工方法，该施工系统包括：钢管桩和导管架，所述导管架内插于所述钢管桩设置，在所述钢管桩和所述导管架之间形成用于灌注灌浆料的环形灌浆空间；在所述钢管桩内部的泥面标高之上还填充有碎石填充层。施工方法包括：将钢管桩打桩至设计标高；确定所述钢管桩内碎石或瓜子片的填充量；安装导管架；导管架的调平与锁定；向所述环形灌浆空间灌注灌浆料。本申请针对先桩法导管架基础施工，尤其是灌浆连接段在泥面标高以上并且桩径较大的导管架结构，具有施工方法简单、设备要求低、节省海上施工时间、减少灌浆材料损耗率和施工成本等特点，为确保导管架和钢管桩的连接质量提供了有力保障。
