The invention relates to the protection of the environment, and in particular to methods of purification of waters from radioactive and toxic S="ptx2">

The known method reburial of radioactive and toxic waste, including waste disposal in the primary capsule, sinking them to the bottom of the water area, removing them from the bottom, the manufacture of the container, the loading of capsules with the waste encapsulation and subsequent immersion of the container in the bottom waters /1/.

The disadvantages of this method are the complexity and mnogodelnosti the manufacture of containers, their low capacity and the need for transportation of containers with special vehicles to the place of burial.

The closest is the way reburial of radioactive and toxic waste in large containers on the bottom, including the manufacture of pre-stressed concrete Thor-capacity, transportation of its surface waters to the location of the container, sinking her to the bottom waters and fixed opposite the location of the container, the loading of the waste container, lifting it to the surface waters and subsequent transportation to the place of disposal of waste /2/.

The disadvantages of this method is that it does not provide for the disposal of waste in kruper the conditions of the container and lifting it to the surface of the waters.

The technical challenge is to simplify the method of reburial of large containers and submarines from the bottom of the waters, while ensuring environmental process reliability and safety by eliminating tilting and possible signs of resonance hoisting-and-transport vehicle and the container in the smooth lifting and transportation.

The problem is solved in such a way that in the way that the reburial of radioactive and toxic waste in large containers with bottom waters, including the production of top-capacity, transportation of its surface waters to the location of the container, the dip and fixed opposite the location of the container, loading container, rise to the surface waters and subsequent transportation to the place of burial, according to the invention torus tank is made with an internal diameter commensurate with the length of the container, and inlet hatches for ballast water, equipped with perimeter rope hoist mechanisms and skipping ropes in mutually perpendicular directions for education lattice bottoms, transported Thor-the capacity of surface waters to the place, salati pull and consistently fail under the container by pushing ropes in thickness of bottom waters during simultaneous reciprocating movement to the formation of the lattice bottoms tor-capacity, then the ends of the ropes cut off and fixed on the outer side of the torus capacity with damping anchors, then produce lift Thor-capacity on the surface of the waters by filing in the cavity tor-capacity air, and the subsequent transport of surface waters to the place of burial.

The proposed method differs from the known fact that the torus tank is made with an internal diameter commensurate with the length of the container, and an inlet hatches for ballast water, equipped with perimeter rope hoist mechanisms for skipping ropes, which have mutually perpendicular directions for the formation of a lattice-plate. Thor-capacity dipped by intake of ballast water so that the container is located inside the torus, and then produce the tension and their penetration into the thickness of the bottom waters in reciprocating motion by means of winches up until the ropes, digging in the mud, will not be placed under the container. Then the rope tightened and cut off from the winch, locking the ends on the outer side of the torus capacity with damping anchors. Thor-the capacity to raise the water surface by forcing air into the cavity top-emkosti containers, including submarines, without tilting them and ensure the safety of the process, because it eliminates the possibility of resonance of the vehicle with the load effect of the soft mounting latticed bottom and streamlined top-capacity, continuously interacting with the water environment of the area. The reciprocating motion of the ropes provide a loosening of the bottom waters and facilitate their depth when driving rods-pushers and available under the bottom of the container.

The method is illustrated in the drawings, which depict: Fig.1 - tor-capacity Assembly (top view); Fig.2 - I-I of Fig.1; Fig.3 - same as in Fig. 1, when loading the container; Fig.4 - I-I of Fig.3; Fig.5 - same as in Fig. 4, after loading the container; Fig.6 - same as in Fig.5, when afloat.

The method is as follows.

Thor-container 1 is produced in the coastal area of pre-stressed concrete or metal inlet manholes 2. The inner diameter of the torus capacity should be commensurate with the size recycling container 3 for free its placement inside the torus and torus capacity assigned based on characteristics of the recyclable container. Top-container is about perpendicular directions for the formation of the bottom 6. The cable hoist mechanism 4 consists of a pair located on opposite outer sides of the torus vessel 1 reversible winches 7 (pulling and braking), rope 5, the guide rollers 8, the vertical rod pushers 9. If necessary, the cable hoist mechanism 4 are equipped with devices for additional loosening of the soil. Next to Thor-the container 1 around the circumference of the fixed four separate guide wire with anchors at the ends (not shown) and fixed spur-bearing 10.

Thor-capacity 1 swimming or tow is transported to the location of bulky waste container 3, ropes 5, located in mutually perpendicular directions, pushing and immersed torus capacity on the bottom as follows. In the cavity of the torus vessel 1 through the inlet 2 hatches fill the ballast water from the basin and lower guides cables, fixing them on the perimeter of the recyclable container 3. After filling the cavity with water tor-capacity begins to gently sampaguita on guide ropes and is located on the bottom so that the recyclable container 3 is placed between the ropes 5 inside of the torus (see Fig.1 and 2). For fixing the position put forward spurs-support 10. Then the rope 5 is pulled by winches 7. Impacts by means of a pair of winches 7 produce reciprocating motion of the rope 5, which in turn is slid under the bottom of the container 3 to the formation of the lattice bottom 6 top-container (see Fig.3, 4). After that the ends of the ropes cut off from winches and fixed on the outer side of the torus capacity with damping anchors 11 (see Fig.5). Then, in the cavity of the torus vessel through the inlet hatch 2 pumped air to the displacement ballast water from it, and Thor-capacity smoothly vertically along the guides up to the surface of the waters, rising disposable container 3 formed of ropes 5 lattice plate 6 (see Fig.6).

Thor-container 1 with a container 3 is transported by surface waters with a tug to the place of burial.

Smooth transportation provides a flexible slatted bottom 6.

The proposed method will allow you to raise from the bottom of the waters of the large containers with radioactive and toxic waste, including to raise sunken submarines, ensuring environmental safety due to the volume of the enclosing container without tilting, smooth tear it from the bottom, lifting and soft transportation on the surface of the waters.
