Problems solved by technology

However, directly repairing the slope of the existing garbage dump is prone to the risk of slope slippage, and it is difficult to guarantee the stability of the slope after repairing. The vacated effective storage capacity and continued landfilling of garbage will increase the possibility of slope instability.

Embodiment Construction

[0016] Such as figure 1 As shown, the schematic diagram of slope shaping of a large garbage dump is composed of compacted garbage 1, tiled geogrid 2, U-shaped rivets 3, folded geogrid 4, geotechnical connecting rod 5, and bagged gravel 6. The compacted garbage 1 is placed on the fully paved geogrid 2, and the compacted garbage pile must be rolled repeatedly to reduce the settlement of the garbage in the later stage. The tiled geogrid 1 is fixed with U-shaped rivets 3 to prevent the grid from shifting. When construction is compacting the rubbish heap 1, bagged crushed stones 6 at the edge of the pile are piled up simultaneously, and the particle diameter of the crushed stones is 5-16mm. The upper part of the compacted garbage 1 is folded back to a certain length to lay the geogrid 4 flatly, and the folded geogrid 4 is reserved for the bottom of the compacted garbage 1 to lay the geogrid flatly, and the bagged gravel 6 at the edge of the compacted garbage 1 is wrapped. The bot...

Abstract

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 operation of the landfill. The construction process is simple.

Description

technical field [0001] The invention belongs to landfill treatment of urban and urban domestic garbage, in particular to a construction method for slope shaping of large garbage dumps. Background technique [0002] With the development of urbanization in our country, people's living standards have improved significantly, but the disposal of domestic waste brought about by urbanization has become more and more difficult. Under normal circumstances, domestic waste is mainly disposed of in two ways: landfill and incineration, among which landfill is widely used due to its low investment, simple process, and large processing capacity. In big cities, due to the scarcity of land resources and the location of waste landfills cannot be too far away, the construction land for domestic waste landfills is very tight, and it has become increasingly difficult to increase the storage capacity of domestic waste landfills simply by opening up new plots . In the large landfills that have b...
