Buoyancy type ocean pile foundation anti-pulling detection device and mounting method thereof
The invention relates to the technical field of offshore anti-pulling detection, and discloses a buoyancy type ocean pile foundation anti-pulling detection device and an installation method thereof.The buoyancy type ocean pile foundation anti-pulling detection device comprises a hoop device and two dynamic positioning ship rafts, a girder is arranged between the two dynamic positioning ship rafts, and a disc is fixedly arranged at the position, coaxial with a pile foundation, of the center point of the girder; the top end of the hoop device is fixed below the disc through a plurality of steel bars. The hoop device comprises an inner hoop and an outer hoop which are fixedly connected, the inner hoop tightly holds the pile foundation, a plurality of grooves are correspondingly formed in the outer side of the inner hoop and the inner side of the outer hoop, and compressed springs are arranged in the grooves; a water suction pump on the dynamic positioning ship raft equivalently pumps seawater out of the dynamic positioning ship raft, and pile foundation uplift detection is carried out. The pile foundation spring type hoop device tightly holds the pile foundation, the compressed spring generates acting force between the outer side of the inner hoop and the inner side of the outer hoop, the acting force generated on the outer side of the inner hoop increases the friction force between the inner hoop and the pile, and the problem that the pile and the hoop device in a traditional single hoop detection device slide relatively is effectively solved.
本发明涉及海上抗拔检测技术领域，其公开了一种浮力式海洋桩基抗拔检测装置及其安装方法，包括抱箍装置和两艘动力定位船筏，大梁设于两艘动力定位船筏之间，大梁中心点与桩基同轴位置固定设有圆盘；抱箍装置顶端通过多根钢筋固定于圆盘下方；抱箍装置包括固定相连的内箍和外箍，内箍抱紧桩基，内箍外侧和外箍内侧排布对应设置多个凹槽，凹槽内设有压紧的弹簧；动力定位船筏上抽水泵等量地将海水从动力定位船筏抽出，进行桩基抗拔检测。本发明由桩基弹簧型抱箍装置抱紧桩基，压紧的弹簧在内箍外侧与外箍内侧之间产生作用力，产生在内箍外侧的作用力增加了内箍和桩之间的摩擦力，有效解决传统的单抱箍检测装置中桩和抱箍装置发生相对滑动的问题。
