Modular apron board pile shoe of self-elevating drilling platform and drilling platform
The invention discloses a modular apron board pile shoe of a self-elevating drilling platform. The modular apron board pile shoe is characterized by comprising a pile shoe body and a plurality of apron board modules uniformly distributed on the outer side of the pile shoe body at intervals, wherein each apron board module comprises an apron board connector connected to the outer side of the pile shoe body and an apron board main body connected to the bottom of the apron board connector, the apron board main body is of a closed structure or a semi-closed structure, and the lowest point of the apron board main body is lower than the lowest point of the pile shoe body. The apron board main bodies in the apron board modules are inserted into a hard soil layer before the pile shoe body, so that a hard-upper-layer and soft-lower-layer egg shell stratum can be damaged in advance, namely the structure of the hard soil layer is damaged, the bearing capacity of a foundation is reduced, and the puncture risk in the pile inserting process is reduced; and gaps exist between the apron board modules, soil at the bottom of the pile shoe body is extruded and then discharged from the gaps between the apron board modules, a soil backflow channel is formed, and the influence of the apron board modules on ballast in a soft soil layer is reduced.
本发明公开了一种自升式钻井平台模块式裙板桩靴，其特征在于：包括桩靴本体以及间隔均布地布置在所述桩靴本体外侧的若干裙板模块；所述裙板模块包括裙板连接体，连接在所述桩靴本体的外侧；裙板主体，连接在所述裙板连接体的底部，所述裙板主体为封闭结构或半封闭结构，所述裙板主体的最低点低于所述桩靴本体的最低点。本发明的裙板模块中的裙板主体先于桩靴本体插入硬土层中，能够提前破坏上层硬下层软的“鸡蛋壳”地层，即破坏硬土层结构，降低地基承载力，从而减小插桩过程中的穿刺风险；裙板模块之间存在间隙，桩靴本体底部土体被挤压后从裙板模块之间的间隙中排出，形成土体回流通道，减小裙板模块对软土层中压载的影响。
