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.
 Reservoir construction method / 2264504
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.

The invention relates to the construction, in particular, to the design of the metal tank of large capacity for storage of hydrocarbons floating roof. Known metal tanks for storage of hydrocarbons, including wall and the bottom rigidly interconnected by means of a welding seam [1]. The disadvantage of tanks is - the presence of high meridional stresses in the wall due to the inability of radial displacements of the wall in the coupling zone of the latter with the bottom, causing the need to increase the wall thickness and the practical impossibility of using the progressive method of rolling in the construction of the reservoir; - the presence of overvoltage cylindrical wall due to non-uniform sediment soil Foundation. The closest technical solution is the storage tank for petroleum products, including wall and bottom, paired together with the compensation element made in the form of concave corrugated annular member, parallel to the wall is completely sealed the partition is established in the form of vertical ribs to form between it and the wall of the square ring gap with a width equal to its height, which is filled with oil-resistant elastic rubber seal, and Palast settled between concave corrugated annular element, wall and bottom is filled with degassed, incompressible and non-freezing liquid [2]. The disadvantage of this solution is - complex technical and design of the compensation element; - presence in the compensation element unreliable oil resistant seals, which breaks down in practice because of the aging of adhesive bonding rubber to metal, before the expiry of object; - in addition, during the construction of the tank, it is very difficult to fill the inner cavity of the compensation element degassed, incompressible and non-freezing liquid, which generally reduces the overall operational reliability of the object. The objective of the invention is the maximum reduction of the meridional stresses in the metal wall of the tank of large capacity for storage of hydrocarbons, with increased operational reliability of the object. The objective of the invention is achieved in that in a metal tank of large capacity for storage of hydrocarbons, comprising a wall and a bottom interconnected by means of a compensation element, which is the form of an annular parabolicheskogo element located vertically between the tank wall and an annular stiffening rib, hermetically fixed in the circular direction on the bottom of the reservoir is of Varos and having a working height h three times, than the diameter d of the ring parabolicheskogo member, an annular parabolicity element their upper ends also completely sealed in the annular direction respectively on the ribs and the vertical wall of the tank. At the same time to reduce friction wall on the bottom around the outer circular perimeter of the vertical wall of the tank can be mounted roller bearings to protect them from the effects of atmospheric horizontal visor. Figure 1 shows a cross section of a metal tank in the loaded condition. Figure 2 shows the site As presented in figure 1. Figure 3 shows the cross-section 1-1 in figure 1. In the drawings denote: 1 - wall tank; 2 - bottom; 3 - ring parabolicity element; 4 - ring vertical ribs; 5 - roller bearing; 6 - horizontal visor; 7 - the subgrade tank; 8 - stored oil. Metal tank of large capacity for storage of hydrocarbons, including the wall 1, freely resting on the bottom 2, which are interconnected compensation element made in the form of an annular parabolicheskogo item 3 (1, 2, 3), located vertically between the wall of the tank 1 and the annular rib 4, hermetics is fixed in the circular direction on the bottom 2 of the tank and having a working height h three times, than the diameter d of the ring parabolicheskogo member, an annular parabolicity element 3 with its upper ends, also completely sealed in the annular direction respectively on the rib 4 and the vertical wall of the tank 1. The height of annular ribs 4 is 3 times larger than the diameter forming parabolicheskogo item 3 on the basis of ensuring the conditions of equilibrium and reliable retention of the specified element 3 in the working position only by friction forces and hydrostatic pressure of the oil product 8, which hold parabolicity element 3 at the specified position, even without considering the strength of the weld. To minimize friction wall on the bottom on the outer side around the perimeter of the reservoir are mounted roller bearings 5, and to protect this site from external atmospheric influences of the latter provided with a horizontal visor 6. The proposed design of the ring parabolicheskogo element 3 allows you to take its thickness for tanks with a capacity of 50 thousand m3less than 1 mm even with multiple reserves of strength that will allow you to practice effectively reduce all meridional stresses in the wall of the tank 1 to zero. Effective deformation work breakdown the wall 1 and bottom 2 of the tank allows in practice to eliminate any potential appearance in the wall of the tank 1 of any additional stress from a hard pinch, and from temperature effects and non-uniform deformation of the soil Foundation that will allow us to greatly reduce the corrosion rate of the metal, and to improve environmental safety and overall operational reliability of the tank.
