Lock catch steel pipe pile cofferdam for offshore inclined bare rock bearing platform construction and construction method of lock catch steel pipe pile cofferdam
The invention provides a lock catch steel pipe pile cofferdam for construction of an offshore inclined bare rock bearing platform, which is characterized by comprising a cofferdam body formed by folding a plurality of lock catch steel pipe piles, ring beams are respectively mounted on the inner side and the outer side of the cofferdam body, concrete is poured in gaps around the lock catch steel pipe piles, and meanwhile, the ring beams are connected with the lock catch steel pipe piles. An inner supporting structure is arranged in the cofferdam body. The steel pipe piles are embedded in the bedrock through the guide holes, underwater excavation of the bedrock is changed into dry operation excavation of the bedrock, the strength and integrity of the bedrock are fully utilized to stop water, underwater concrete is not needed to stop water, and the length of the steel pipe piles can be freely adjusted to adapt to an inclined seabed surface; the lock catch steel pipe pile cofferdam and the complete bed rock of the seabed form a whole through underwater concrete, the steel pipe columns can be reused, steel is saved, the usage amount of bottom sealing concrete is saved, and the construction efficiency is improved.
本发明创造提供了一种海上倾斜裸岩承台施工用锁扣钢管桩围堰，其特征在于：包括由若干锁扣钢管桩合拢成的围堰本体，并在围堰本体内侧和外侧分别安装圈梁，并在锁扣钢管桩周围缝隙浇注有混凝土，同时，在围堰本体内设有内支撑结构。本发明创造通过引孔将钢管桩埋入基岩内，将水下开挖基岩变成干作业开挖基岩，充分利用基岩自身的强度和完整性来止水，而不用水下混凝土来止水，可利用钢管桩长度可以自由调整来适应倾斜的海床面，通过将锁扣钢管桩围堰与海床完整的基岩通过水下混凝土形成整体，钢管柱可以重复利用，节约钢材，节约封底混凝土用量，提高施工效率。
