The invention provides an underwater packer. The underwater packer comprises an outer pile, a sleeve arranged in the outer pile, a plug arranged at the bottom end of the sleeve, a grouting pipeline arranged on the sleeve, a plurality of resin turning plates annularly distributed between the outer pile and the sleeve, and sealing cloth connected between the adjacent resin turning plates in a hot melting mode. The bottom end of the resin turning plate is hinged to the plug, and the top end of the resin turning plate abuts against the inner wall of the outer pile. A sealing bag is omitted, the resin turning plate plays a role in bearing and sealing, the outer wall of the outer pile and the inner wall of the sleeve are both in direct contact with grout, and the outer pile and the sleeve are connected firmly. The inclined face of the top of the resin turning plate and the extrusion face of the protruding part abut against the inner wall of the outer pile, double-layer sealing is achieved, and slurry leakage is avoided. In addition, the sealing cloth and the annular sealing film are arranged, so that the sealing effect is further enhanced; and when the length e of the resin turning plate is equal to (a-0. 5c-0. 5b)/cos (90 degrees-g), the sleeve is inserted into the outer pile from any position, so that the resin turning plate can be ensured to have better sealing performance, and the manufacturing cost of the resin turning plate is the lowest.
本发明提供了一种水下封隔器，包括外桩，置于外桩内的套筒，设置在套筒底端的插头，设置在套筒上的灌浆管线，若干个环布在外桩和套筒之间的树脂翻板，热熔接在相邻树脂翻板之间的密封布；所述树脂翻板底端铰接在插头上，所述树脂翻板顶端抵接外桩内壁。省略了密封袋，树脂翻板既起到承重作用又起到密封作用，外桩外壁和套筒内壁均直接接触浆液，两者连接牢固更强；树脂翻板顶部的斜面以及凸出部的挤压面均抵接外桩内壁，双层密封，不会漏浆；此外，还设有密封布、环形密封膜，进一步加强了密封效果；得出树脂翻板长度e＝(a‑0.5c‑0.5b)/cos(90°‑g)时，套筒从任何位置处插入外桩内，都可保证树脂翻板具有较好的密封性，且树脂翻板的造价成本最低。
