The utility model discloses a connect sealing device for prevent osmosis membrane perpendicularly, its characterized in that it is a cavity to connect sealing device, two at least difference holdings have in the cavity prevent osmosis membrane starting and destination point's sleeve pipe, the sleeve pipe with it has the agglutinate layer to prevent filling in the space between the osmosis membrane tip. The utility model has the advantages that, it has increased the infiltration route of preventing osmosis membrane end connection department to connect sealing device, makes and prevents that osmosis membrane has good ductility, can the hermetic seal when fixed connection prevents osmosis membrane, still have the ability of resisting the soil body and being out of shape to and stronger chemical stability, used material structure is simple, convenient to use.
