[0002] Fly ash contains harmful substances such as dioxins and heavy metals, and the treatment method usually adopted is landfill. The process is that the fly ash is first transported to the treatment plant, treated, and then packed in ton bags and transported to the landfill for landfill. In order to prevent the fly ash from contacting the groundwater, the landfill site is usually large and located in an area with stable geological conditions, far away from the fly ash treatment plant; the landfill often adopts an inverted trapezoidal structure, and the ton bags are hoisted into the foundation pit during landfilling, and then compacted and covered.

[0003] The problems are: 1. Since the upper end of the ton bag is an open structure, the dust generated during the packaging, transportation, lifting, landfill compaction and other processes will cause secondary pollution to the environment along the way and in the surrounding areas.

[0004] 2. Since the foundation pit of the landfill is an inverted trapezoidal structure, and the fly ash poured into ton bags is approximately columnar, a large porosity will be generated on the slope of the foundation pit during landfilling, which is not easy to compact, making it difficult to collect and treat the leachate and biogas.
