FIELD: construction.SUBSTANCE: invention is designed for use in hydraulic engineering, in particular, to create dams of tailing dumps in areas with significant anthropogenic load on water facilities. The method includes preparation of the base for the dam and laying of soil material into the dam bank. Soil material is represented by anthropogenic bottom deposits of contaminated water facilities having permissible filtration capacity and sufficient strength according to hydroeconomic calculations. Anthropogenic bottom deposits are previously prepared by dehydration in containers from geotextile material to moisture of 40-50% and compaction under by gravity on a specially prepared site. Afterwards containers with dehydrated residue are delivered to the place of construction by dump trucks and are laid by mobile cranes in layers. The promising direction is usage of this device in areas of far north, since in these areas usually there are no sufficient soil materials suitable for creation of antifiltration elements. Local materials used to fill the dam bank are in permafrost condition and their usage causes significant difficulties. Utilisation of heterogeneous bottom deposits is provided, environmental compatibility and fail-safety of dam operation increase, erected structures are more stable.EFFECT: reduced filtration losses, timing of construction, minimised complexity and labour intensiveness of works. |
