Improved underwater packer
The invention provides an improved underwater packer which comprises an outer pile and a sleeve arranged in the outer pile, the outer pile and the sleeve form an annular gap, and the improved underwater packer is installed in the annular gap; the improved underwater packer comprises an annular sealing bag, a plurality of turning plates connected to the annular sealing bag, a pressing part, a traction part and a grouting pipeline. The outer side edge of the annular sealing bag is pulled by a pulling part, the inner side edge of the annular sealing bag is pressed by a pressing part to form a bottom sealing part, and an outlet of the grouting pipeline is connected with an inlet of the annular sealing bag; the pressing and holding component and the traction component are connected to the outer wall of the sleeve or the inner wall of the outer pile, and after grouting, the annular sealing bag presses the turning plate to turn over and block the annular gap. According to the improved underwater packer, gaps of any size can be blocked, the structure is simplified, the sealing effect is good, and slurry leakage can be effectively prevented.
本发明提供了一种改进型水下封隔器，包括外桩和置于外桩内的套筒，所述外桩和套筒形成环形间隙，所述改进型水下封隔器安装在环形间隙中；所述改进型水下封隔器包括环形密封袋，若干个连接在环形密封袋上的翻板，压持部件，牵拉部件，灌浆管线；所述环形密封袋外侧边被牵拉部件牵拉，所述环形密封袋内侧边被压持部件压持形成底部密封部件，所述灌浆管线出口和环形密封袋入口连接；所述压持部件和牵拉部件连接在套筒外壁上或外桩内壁上，灌浆后，所述环形密封袋压动翻板翻转并封堵环形间隙。本发明提供的改进型水下封隔器，不仅可封堵任意大小的间隙，且简化了结构，密封效果好，能有效防止漏浆。
