Large-scale garbage dump slope shaping construction method

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...
