Zusammenfassung: | The utility model relates to a subaqueous patch sealing device processed by a vacuum pre-pressing weak subgrade, consisting of a glue injection pump, a glue transmission pipe, an elastic clamp with upper and lower clamping plates and a pressing block; wherein, one end of the glue transmission pipe is communicated with the glue injection pump, and the other end thereof is fixed on the inner side of the lower clamping plate of the elastic clamp; the front part of the pressing block is positioned between the upper and the lower clamping plates of the elastic clamp. When in use, the edge part of a patch film plate is clamped between the pressing block and the lower clamping plate, the patch film plate is adhered to a tear which is to be mended under water. When the glue injection pump is started, glue liquid flows from the glue transmission pipe fixed on the inner side of the lower clamping plate and reaches between the patch film plate under the pressing block and the sealing film which is to be patched.
