Metal vertical cylindrical reservoir with double bottom for storage of liquid products In reservoir between the main bottom and an additional vertical wall there is a flat circular element and a thin elastic distributing gasket. Stiffening ribs are welded to an additional vertical wall, normally to its surface, and also to edges of the main and additional bottom. |

Structure to hold liquids of large volumes on heterogeneous base Structure for storage of liquids of large volumes on a heterogeneous base comprises a support foundation slab and a reservoir installed on it. The support foundation slab is made with an inclined foot, having alternating thickness with the thickening difference b=0÷1h in the area of the suggested tilt, where the h is the rated thickness of the support slab. The reservoir is installed with displacement of its centre, relative to the centre of the support foundation slab by the value a=0.1÷0.4(D2-D3) towards the side opposite to the direction of the suggested tilt, where D3 - reservoir diameter, D2 - diameter of the support foundation slab. |

Metal reservoir of large volume for storage of hydrocarbons Metal reservoir includes wall and bottom connected to each other with the help of compensation element. Compensation element is arranged in the form of circular parabola-shaped element arranged strictly vertically between wall of reservoir and circular stiffening rib fixed tightly in circular direction at reservoir bottom and having working height h, which is three times more than diametre d of circular parabola-shaped element. Circular parabola-shaped element by its upper ends is also absolutely tightly fixed in circular direction accordingly on stiffening rib and vertical wall of reservoir. |

Cylinder-shaped reservoir for oil products storage Reservoir is mounted on a foundation and consists of a tapered bottom, a body wall, a floating roof with a rim seal, a receptor-and-dispenser unit, a drainage unit and a device for bottom sedimentation washaway. The receptor-and-dispenser unit is mounted inside the foundation in immediate proximity to the bottom taper base; the drainage unit and the device for bottom sedimentation washaway are mounted below the bottom taper vertex; the floating roof design provides for maintenance of technological clearances between the roof and the reservoir top edge and between the roof and the bottom taper vertex when the roof is in the uppermost and lowermost positions accordingly. |

Large reservoir for oil product storage Reservoir comprises wall and bottom connected one to another by compensating member. The compensating member is made as concave corrugated annular member. Partition made as vertical stiffening rib is installed in parallel to wall in air-tight manner so that annular gap is created between the wall and the partition. The gap is filled with elastic rubber oil-resistant material. Cavity between concave annular member, wall and bottom is filled with degassed incompressible liquid and with nonfreezable liquid. Roller frictionless bearings are installed from outer side along the full wall perimeter. Vertical annular stiffening rib is located beyond the bearings so that the stiffening rib, the bearings and the wall define annular gap filled with rubber sealant and then with elastic oil-resistant member. |

Method involves preparing building site and ground base; mounting reservoir and performing hydraulic tests thereof. Reservoir mounting is performed in several stages. At the first stage reservoir is built without stationary metal bottom, has projected edges and is provided with temporary flexible bottom air-tightly pressed against projected edges with the use of pneumatic system. After that preliminary hydraulic tests are performed by filling reservoir with water. At the second stage temporary flexible bottom is demounted after complete ground base compaction, deformed ground base is smoothed up to reaching design mark by filling the formed cavity with filling material. Then waterproofing material is applied to smoothed base, permanent metal bottom is formed and the ready vessel is subjected to final hydraulic tests. |

Foundation includes ring-shaped foundation member located under reservoir walls and base formed as a row of piles driven in ground and connected by ring-shaped end cross having cuts. Reservoir bottom center includes plate with levers located in ring-shaped end cross cuts and connected to ring-shaped foundation member by rods. |

Storage structure for liquid hazardous materials Structure includes pit and reservoir with hazardous material to be stored arranged in pit. Reservoir is made as elastic water-proof bag. Pit walls and bottom are waterproofed. Pit has width L ≥ 4R and depth H ≥ 3R. Pit is filled with water up to H-h level, where h is unfilled pit part height. Volume of unfilled pit part exceeds reservoir capacity volume. Reservoir is floating in pit and spaced a distance from walls and bottom thereof. The distance is not less than reservoir radius R. Reservoir is connected to pit walls by flexible ties or netted system to provide control of reservoir location inside the pit. |
