Large-scale garbage dump slope shaping construction method

The invention discloses a large-scale garbage dump slope shaping construction method, which is characterized by comprising the following steps: step A, laterally opening a film in the upper part of agarbage dump to separate the construction section from the upper film, and then disassembling at two ends of a transverse slit, and separating the film and simultaneously packaging and binding the separated films and transporting the films out of the construction area; B. vertically excavating the garbage slope from the outside to the inside at the first construction section; C. laying tiled geogrids at the bottom of the dump pit and anchoring with U-shaped rivets; D. piling up bagged gravels in the marginal area of the garbage slope; and E, backfilling the garbage and wrapping the gravel jutebags with the folded geogrids at the edge of the garbage slope. The upper and lower layers of tiled geogrids are connected by connecting rods so as to form a high-quality and stable garbage slope toensure sustainable operatio
