The utility model relates to a wetland environmental protection field especially relates to build special structure of backfilling of wetland. Contain the limit wall, the bian bi cross -section is trapezoidal, contains plain soil layer above this limit wall, element soil layer top contains a retaining space, and a permeability cell is stretched out in the retaining space, still contains the packing layer, and the water pipe has been placed to the packing layer top, contains the soil horizon above the water pipe, the soil horizon contains down, and bulge stretches into the packing layer. Beneficial effect: down bulge is arranged in the packing layer, and past the time, can be packed purify sewage from the packing layer, and through purifying the back, because bulge stretches into the packing layer, the water after the purification can get into the soil horizon, can not cause the influence to the plant on the soil of top.
