Underwater packer with high sealing reliability
The invention provides a high-sealing-reliability underwater packer. The high-sealing-reliability underwater packer comprises an annular sealing bag, a turning plate assembly, a pressing and holding part, a traction part and a grouting pipeline, wherein the turning plate assembly is annularly connected to the outside of the annular sealing bag; the turning plate assembly comprises a turning plate and a wing plate connected to one side of the turning plate, and rubber layers are bonded to the surfaces of the turning plate and the wing plate in a vulcanized mode. After grouting, the annular sealing bag presses the turning plate assembly to turn and block the annular gap, and the wing plate blocks the gap between the adjacent turning plates. According to the underwater packer with the high sealing reliability, the surfaces of the turning plates and the wing plates are bonded with the rubber layers in a vulcanized mode, so that the tops of the turning plates and the wing plates are in flexible contact with the outer wall of the sleeve or the inner wall of the outer pile, the adjacent turning plate assemblies are in flexible contact, and the bottom ends of the turning plate assemblies are in flexible contact with the upper surface of the annular supporting plate; and the top end of the turning plate assembly is in flexible contact with the inner wall of the outer pile, so that the sealing performance of the underwater packer is greatly improved, slurry leakage can be effectively prevented, and a secondary sealing guarantee is provided for the annular sealing bag.
本发明提供了一种高密封可靠性水下封隔器，包括环形密封袋，环布连接在环形密封袋外的翻板组件，压持部件，牵拉部件，灌浆管线；翻板组件包括翻板以及连接在翻板一侧的翼板，翻板和翼板表面硫化粘接有橡胶层；灌浆后，环形密封袋压动翻板组件翻转并封堵环形间隙，所述翼板封堵相邻翻板间隙。本发明提供的高密封可靠性水下封隔器，翻板和翼板表面硫化粘接有橡胶层，使翻板和翼板顶部与套筒外壁或外桩内壁之间为柔性接触，相邻翻板组件之间为柔性接触，翻板组件底端和环形支撑板上表面为柔性接触，翻板组件顶端和外桩内壁为柔性接触，大大提高了水下封隔器的密封性，可有效防止漏浆，为环形密封袋提供了二道密封保障。
