Slope protecting and reinforcing structure for island-building cofferdam

The utility model relates to an island-building cofferdam side slope protection reinforcing structure which comprises a film bag laid on a side slope and a grouting anchor rod used for grouting the film bag, the grouting anchor rod is arranged on the film bag in a penetrating mode and is anchored downwards to the position below a riverbed scouring line along the side slope, and the lower portion of the side slope is backfilled with backfill soil covering the lower portion of the film bag. A plurality of grouting holes are formed in the outer wall of the grouting anchor rod at intervals. The film bags are filled with concrete through the grouting anchor rods to reinforce and protect the side slope of the island-building cofferdam, and therefore the technical problem that in the prior art, the side slope of the island-building cofferdam for construction of the in-shore structure of a bridge is seriously scoured by water flow is solved. And the anchor rod goes deep below a river scouring line, so that the anti-s
