"Pile first method" interpolated jacket foundation construction system for implantable rock-socketed pile
This application discloses a "pile first method" interpolated jacket foundation construction system for an implantable rock-socketed pile. The construction system comprises a steel pile casing, a steel pipe pile prefabricated with pile core bottom sealing concrete and a jacket; the steel pile casing is sank to a preset position, the steel pipe pile prefabricated with the pile core bottom sealing concrete is implanted in the inner side of the steel pile casting, and a first annular space among the bottom of the steel pipe pile, the steel pipe pile and a rock-socketed hole wall and a second annular space between the steel pipe pile and an overburden layer are both prefabricated with grouting pipelines; and after the first annular space and the second annular space are grouted, the tip part of a pile leg column of the jacket is inserted into the steel pipe pile and fixedly connected with the steel pipe pile, and a third annular space is prefabricated with a grouting pipeline. This systemproposes to pre-pour pile core the concrete to seal the bottom in the pile before the steel pipe pile is shipped, the construction risk is reduced, a offshore construction window is saved, the construction quality of the pile core concrete and the grouting construction quality of a rock-socketed section are ensured, and at the same time, the grouting quality of the rock-socketed section is ensured.
本申请公开了植入式嵌岩桩的“先桩法”内插式导管架基础施工系统，施工系统包括：钢护筒、预制有桩芯封底混凝土的钢管桩和导管架；将钢护筒沉桩至预设位置，预制有桩芯封底混凝土的钢管桩植入钢护筒内侧，钢管桩底部、钢管桩和嵌岩孔壁之间的第一环形空间、钢管桩和覆盖层之间的第二环形空间均预制有灌浆管线；待第一环形空间和第二环形空间灌浆完成后，将导管架的桩腿柱插尖部位插入钢管桩内并与钢管桩固定连接，第三环形空间预制有灌浆管线。本申请提出了在钢管桩出运前预先浇筑桩芯混凝土进行桩内封底，不仅降低了施工风险，节省了海上施工窗口，更保证了桩芯混凝土施工质量和嵌岩段灌浆施工质量，同时确保嵌岩段灌浆质量。
