FIELD: construction. SUBSTANCE: 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. EFFECT: prevents reservoir tilting under cyclic loads in process of operation due to bringing of centre subsidence differences and reservoir edges to normative values. 2 dwg
The invention relates to the construction, in particular to structures for storage of liquids in large volumes located on a heterogeneous basis, typically the slopes. The known method of the device of buildings and structures on a slab Foundation on any soil Foundation, in particular folded weak or loose soils large capacity (see RF patent №2352723; CL E02D 35/00; 2009 - equivalent). The disadvantage of this method is the complexity of its implementation and the need for geodetic observations during the first years of operation. Know the construction of oil storage in earthquake-prone areas, including the device reservoir on slab foundations (see RF patent №2182952; CL EN 7/00; 2002 - prototype). A disadvantage of the known construction of the Foundation of the tank is that when using this Foundation tank on the ground with uneven (the cross) deposition of engineering-geological elements does not ensure uniform sediment, resulting in possible roll. The technical result of the problem is the elimination of roll of the vessel under cyclic loads during operation by adjusting the difference between the sediment centre and edges of the tank to the specified values. The technical result is achieved by the fact that in the construction of DL the storage of large amounts of liquids at heterogeneous base, including the supporting base plate and installed on the tank, according to the invention the supporting base plate is made with an inclined sole that has a variable thickness with a difference thickening b=0÷1h in the area of the proposed roll, where h is the design thickness of the base plate and the tank is installed on the supporting base plate shifting its center relative to the center of the supporting base plate on the value of a=0,1÷0,4(D2-D3) in the opposite direction of the intended roll 7, where D3 is the tank diameter, D2 is the diameter of the circular support base plate. The novelty of the claimed proposal due to the fact that the use of non-axial arrangement of the supporting base plate and the tank and inclined soles of the supporting base plate with variable thickness, allows to achieve the guideline values for difference between sediment edges and center of the tank, and to avoid roll, when designing tanks on a heterogeneous basis. The invention is illustrated in the drawing, in which figure 1 shows a construction for storage of large amounts of liquids (side view); figure 2 - is a plan (top view). Structure for storing large amounts of liquids consists of bags of gravel-sand mixture 1. diameter D1, which is the supporting base plate 2 with a diameter D2, and undamental plate installed tank 3 with a diameter D3. While supporting base plate 2 is made with an inclined sole that has a variable thickness on the magnitude of b=0÷1h in the area estimated roll (where h is the design thickness of the supporting base plate). The center of the tank 4 is displaced relative to the center 5 of the supporting base plate 2 by the value a=0,1÷0,4(D2-D3) on the horizontal axis 6 in the direction opposite to the direction of the intended roll 7. A specific example of the construction of facilities for the storage of large amounts of liquids is a facility for the storage of petroleum displacement 30000 m3for PPF "Zarechye" (OJSC "Chernomortransneft"), where the diameter of the base plate 2 was D2=52 m, and the diameter of the tank 3 is constituted D3=45,6 m, the shift of the center of the tank 4 relative to the center Foundation 5 amounted to a=1.5 m On the calculation results of the difference precipitate the center and edges of the tank was within normal limits, and roll - was completely absent. Structure for storing large amounts of liquids on a heterogeneous basis, including supporting the base plate and mounted on her tank, characterized in that the supporting base plate is made with an inclined sole that has a variable thickness with a difference thickening b=0÷1h in the area of the proposed roll, where h is the design thickness of the support plate and the tank is installed with an offset of its center relative to the center is and the supporting base plate on the value of a=0,1÷0,4(D2-D3) in the direction opposite direction of the intended roll, where D3 is the tank diameter, D2 is the diameter of the supporting base plate.
