Active puncture antiskid device and method for bottom of pile shoe of self-elevating drilling platform
The invention relates to a self-elevating drilling platform pile shoe bottom active puncture antiskid device which comprises hydraulic jacking puncture mechanisms, a pressure detection mechanism and a data acquisition computer, the hydraulic jacking puncture mechanisms are distributed in the circumferential direction of a pile shoe, the hydraulic jacking puncture mechanisms can actively puncture a stratum, pile anchoring can be achieved at the bottom of the pile shoe, and the pressure detection mechanism can detect the pressure of the pile shoe. The hydraulic jacking puncture mechanism is arranged on the pile shoe to prevent lateral sliding of the pile shoe, a pressure detection mechanism is arranged on the hydraulic jacking puncture mechanism and used for detecting the tripping-in depth and the stress condition of the pile shoe, the pressure detection mechanism is electrically connected with a data acquisition computer, and the data acquisition computer is used for receiving and displaying information detected by the pressure detection mechanism. And the movement of the hydraulic jacking puncture mechanism is controlled according to the detected information. The method is used for actively pre-detecting the bearing capacity of seabed soil near the bottom of the pile shoe, so that an egg shell stratum is actively recognized and removed, and the risk of pile pitching puncture when encountering the egg shell stratum is avoided.
本发明涉及一种自升式钻井平台桩靴底部主动穿刺防滑装置，包括液压顶升穿刺机构、压力检测机构和数据采集计算机，液压顶升穿刺机构分布在桩靴的周向上，液压顶升穿刺机构能够主动穿刺地层，实现桩靴的底部能够锚桩，以防止桩靴侧向滑动，液压顶升穿刺机构上设有压力检测机构，压力检测机构用于检测桩靴的下入深度以及受力情况，压力检测机构与数据采集计算机电连接，数据采集计算机用于接收及显示压力检测机构检测的信息，以实现检测的信息控制液压顶升穿刺机构的运动。本发明用于主动预探桩靴底部附近的海底土承载力，从而主动识别除“鸡蛋壳”地层，避免在遇到“鸡蛋壳”地层时出现插桩穿刺的风险。
