Description

The proposal relates to technology for strengthening and stabilizing coastal soil and amorphous coastal deposits and is intended, in particular, to prevent destruction and detachment of soil-amorphous masses of coastal reservoirs.

Currently, technical means are known for strengthening the banks of reservoirs, the most representative of which contain aggregates for arranging the coastal boundary of a reservoir, including watercraft, and mechanisms for increasing the height of coastal soil [SU 996632, 1979; RU 41312, 2004; SU 1682455, 1991; RU 2232223, 2004; RU 2236500, E02B 3/00, E02D 11/00, 2004]. The last of these technical solutions is the closest in essence and the achieved result.

A significant and obvious drawback of this prototype is the ability to stabilize only the height of the coastal soil when it is densely folded and the absence of technical means to fix unstable coastal amorphous deposits in the form of peat, vegetation and weak landslide soils.

The technical task and the positive result of the proposed technical complex is to increase the reliability of the strengthening process of the coastal boundary of the reservoir, in particular, to prevent separation of unstable amorphous layers of the coastline to prevent the drift of these floating “islands” that interfere with navigation, as well as the operation of hydropower plants.

The specified task, the technical result and the effectiveness of the technical complex are achieved due to the fact that

the technical complex for stabilization of the coastal boundary of the reservoir, including a floating platform, an dredging projectile, is characterized by the fact that the platform is equipped with a grader blade for profiling the crest and slopes of an underground submarine shaft, and is also equipped with grippers for introducing aquatic plants into the submerged shaft, the complex also has an elastic an elongated pipeline, fixed in its initial flattened position on a bobbin, its cavity is filled with hydroreactive polymer material, while the walls of the pipe water feature built in in these valves, to adjust to the pressure of the high and low reservoir water.

Figure 1 shows a schematic flow diagram;

figure 2, 3 - working equipment. The technical complex includes a floating platform 1, a dredging device 2 (dredger), a device in the form of an elongated blade 3 for planning the underwater surfaces of the formed submerged soil shaft 4. If necessary, use a piling unit 5 to exclude shaft movements in the presence of landslide horizons of bottom soil. The upper part of the underwater shaft - its crest is strengthened with the help of water-growing: shrubs, reeds, coogs, etc. The top of the ridge, hidden under the air-water section, can be equipped with long initially flat elastic, or resilient, elements 6 in the form of volumetric, but initially flat, flattened pipelines (sleeves) 7, mounted on a bobbin and filled with a polymer hydroreacting material 8, and in them the walls are fitted with valves 9 and 10, which operate when the water level rises and when the horizon of medium waters decreases, for example, using float regulators.

The technical complex for stabilization of the coastal boundary of the reservoir works as follows. At the coastal boundary, represented by unstable amorphous geological deposits (peat, vegetation, inclusions of soil layers), to prevent their separation from the shore and carried away by currents, atmospheric flows, form an underwater shaft 4; the crest of the shaft is set below the water-air horizon (at the level of "SPM", "UNV") - to exclude stagnation of water in front of the coastline. For this work, they use a floating platform 1 with its technical equipment: a dredging shell 2 excavates part of the bottom soil and form an elongated dump 4 along the coastal boundary. If necessary, for example, in the presence of landslide horizons, the shaft is fixed by immersion of piles using a piling unit 5, the underwater part of the shaft is planned by a planner (blade) 3. Next, water-growing plants are planted along the shaft ridge 4, which are introduced using grabs 11 of platform 1. If In the water area, a significant fluctuation of the water horizons is observed: from “UNV” - “USV” to “UVV”, then the crest of the shaft 4 is equipped with initially flat elongated elements 6, unwinding them from the reels. These elements are filled with polymer hydroreacting material, for example, PGT (polyhydrogel in the form of micro-nanoporous particles). When the water level rises, the valves 9 open, water enters the cavities of the elements 6, the volume of the element increases sharply and the artificially formed elastic crest of the shaft, preventing wave washing of the shore; so that there is no separation of amorphous masses and their ablation does not occur in the open water area of the reservoir. These technological methods prevent peat masses from separating from the coast (in most of the North-West of Russia there are reservoirs with unstable peat banks). And when the water level drops, the valves 9 are closed, and water from the cavities of the element 6 is discharged through the valves 10, lowering the shaft ridge to the original one, so that it is always hidden under water.
