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.

FIELD: construction. SUBSTANCE: horizontal tank on saddle supports includes cylindrical shell, bottoms and has the following relations of basic design parameters: ratio of distance between the edge of cylindrical shell and axis of saddle support to the length of cylindrical shell is K, multiplied by the tank volume to the power of N, besides K varies from 0.37 to 0.42, and N varies from 0.12 to 0.15. EFFECT: optimal installation of saddle supports, providing minimum bending moment, arising in shell, and minimum calculated values of wall thickness of the cylindrical shell. 3 dwg
The invention relates to storage tanks for petroleum products and other liquids and can be used in oil refining, chemical industry and other sectors of the economy. The famous design of the horizontal tank on saddle supports, comprising a cylindrical shell, heads, saddle supports (GOST 17032-2010 "steel horizontal Tanks for petroleum products. Technical terms."). A disadvantage of the known horizontal tank on saddle supports is that it does not establish the optimal installation location on saddle supports from the edge of the cylindrical shell to the axis of the saddle supports. The aim of the invention is to obtain the optimal range of distances from the edge of the cylindrical shell horizontal tank on saddle supports to the axis of the saddle supports. The objective is achieved due to the fact that in the known horizontal tank on saddle supports, comprising a cylindrical shell, heads, saddle supports, the ratio of the distance from the edge of the cylindrical shell to the axis saddle supports to the length of the cylindrical shell is K multiplied by the volume of the tank in degree N, and K varies from 0.37 to 0.42, and N varies from 0.12 to 0.15. Horizontal tank on saddle supports schematically shown n the figure 1. The maximum bending stresses occur over supports or between the supports depending on the distance between the axis of the saddle supports 3 and the edge of the cylindrical shell 1. Values of bending moments in a cylindrical shell defined by the dependencies given in GOST R-2007 "Vessels and apparatus. Norms and methods of strength calculation. The calculation of the shells and heads from the impact of supporting loads". An example of a change of the bending moment over the saddle support M1and between the saddle supports M12for shells with a diameter of 3,200 m, length 12.0 m, 100 m3the distance between the edge of the cylindrical shell and the axle saddle supports e is shown in figure 2. In this example, the intersection of the graphs gives the optimum value of the distance between the edge of the cylindrical shell and the axle saddle supports e=2,7 m Figure 3 presents the graphical dependence of the ratio of calculated optimal values of the distance from the edge of the cylindrical shell to the axis of the saddle support e to the length of the body L of the volume of the tank Vp. Considered standardized horizontal tanks 5, 10, 25, 50, 75 and 100 m3. The curve presented in figure 3, can be approximated by the equation:
When changing K in the range from 0.37 to 0.42, and N from 0.12 to 0.15 deviation of calculated values from equation (1) from the optimal relations e/L shall not exceed 15%. The proposed expressions for positioning saddle supports are optimal and allow for minimal bending moment in the horizontal shell of the tank and, as a consequence, the minimum calculated wall thickness of the cylindrical shell. Horizontal tank on saddle supports, comprising a cylindrical shell, heads, saddle supports, characterized in that the ratio of the distance between the edge of the cylindrical shell and the axle saddle supports to the length of the cylindrical shell is K multiplied by the volume of the tank in degree N, and K varies from 0.37 to 0.42, and N varies from 0.12 to 0.15.
