Self-elevating drilling platform pile shoe bottom bearing capacity hydraulic testing device
The invention relates to a self-elevating drilling platform pile shoe bottom bearing capacity hydraulic testing device, a plurality of hydraulic jacking mechanisms are arranged in the circumferential direction of a pile shoe at intervals, each jacking mechanism is provided with a pressure detection mechanism, and the pressure detection mechanisms are used for detecting the tripping-in depth and the stress condition of the pile shoe; and a data acquisition computer is electrically connected with the pressure detection mechanism and is used for receiving and displaying information detected by the pressure detection mechanism and controlling the pressure hydraulic jacking mechanism to act according to the detected information. A circle of uniformly distributed multi-point hydraulic testing devices are arranged on the peripheral edge of a pile shoe, and before the pile shoe is ballasted to penetrate into a seabed soil layer with uncertain bearing capacity, the hydraulic testing devices around the pile shoe are started to pre-detect the bearing capacity of a soil body, the bearable pressure intensity of the soil body is obtained, and whether an egg shell type stratum exists or not is recognized, therefore, the risk that the pile shoe continues to conduct ballast injection is recognized in advance.
本发明涉及一种自升式钻井平台桩靴底部承载力液压测试装置，沿着所述桩靴的周向方向间隔设有若干个液压顶升机构，每个所述顶升机构上均设有压力检测机构，所述压力检测机构用于检测桩靴的下入深度以及受力情况；数据采集计算机，其与所述压力检测机构电连接，用于接收并显示所述压力检测机构检测的信息，并根据所述检测的信息控制所述压力液压顶升机构动作。通过在桩靴周围边部布置一圈均匀分布的多点液压测试装置，在桩靴被压载贯入承载力不确定的海底土层之前，启动桩靴周围液压测试装置进行土体承载力预探，获取土体可承载的压强大小，以及识别是否存在“鸡蛋壳”式地层，由此来提前识别桩靴继续压载贯入的风险。
