Description

The invention relates to the construction and can be used in the construction of iron concrete tanks for the storage of oil and oil products, mainly gasoline. A known reservoir for petroleum products, predominantly gasoline, including steel walls, a thin flexible sheet sheath attached to the wall, a bottom and a cushion made of a continuous and permeable material, such as oil sand, with a leakage control tube on it, The drawbacks of the tank are low corrosion resistance, in conditions of long-term underground storage of oil. In these words of operation, the danger of loss, tightness has not only the bottom, but also the walls along their entire height with the subsequent penetration of the product into the environment. In addition, in case of loss of tightness of the walls in the area between the shell of the specified reservoir and the bottom, the oil product also gets access directly to the environment. The closest in technical essence to the invention is a reinforced concrete tank for storing petroleum products, including a bearing bottom / wall, an inner steel lining, insulating and filtering layers, a collection of petroleum products and discharge pipes 2. The disadvantages of the known reservoir are also low reliability of environmental protection from pollution with oil products and laboriousness of repair work. The aim of the invention is to increase the reliability of the environmental protection from pollution to oil products and reduce the labor intensity of repair work. The goal is achieved by the fact that in a reinforced concrete tank for storing petroleum products / including a base plate, walls, internal steel cladding / insulating and filtering yolis, a collection of petroleum products and discharge pipes, the filter layer is located under the steel cladding, and the insulating layer is placed on reinforced concrete bottom, with steel cladding installed against the wall with a gap communicated with the filtering layer. At the same time, the steel facing of the bottoms may have a slope from the periphery to the center, and the bottom to the collection of oil product. In addition, the steel facing of the bottom may also have a slope from .., the center to its periphery, and the bottom - to the collection of petroleum products. Moreover, the collection can be made in the form of a perforated pipe or in the form of an ear. FIG. 1 shows a tank with a collection of petroleum products in the form of a perforated pipe, a section; Figure 2 - the same, with a collection of petroleum product in the form of a bottle. The tank includes supporting reinforced concrete walls 1, bottoms 2 t with internal steel cladding 3 and a drainage system consisting of a filtering layer 4, an oil product collection made in the form of a drain 5 or in the form of a seal .6 and a discharge pipe 7. F1 liting layer is located under the steel cladding 3, and the supporting reinforced concrete bottom 2 has an insulating layer 8. The filtering layer can be made of sand, rubble or gravel, and the carrying bottom can be made of reinforced concrete. At the same time, steel ob-JiH4OBKa 3 is installed relative to wall 1 with a gap 9 communicated with filter 5 with a layer 4. The gap 9 is made with minimal dimensions that ensure the penetration of the petroleum product - gasoline down between the steel facing and the reinforced concrete wall. In addition, the steel facing 3 of the bottom 2 has a slope from the periphery to the center of the bottom, or also from the center of the bottom 2 to the periphery, and the bottom itself is always towards the collection 5 or B. Ten days can be created, for example, at the expense of a sheet. In turn, the collection:: nickname 5 or b of petroleum product is located under the carrying bottom 2 in its most reduced part. The oil product assembly can be made in the form of a perforated pipe (drain) or in the form of a primrose. The insulating layer 8 can be made / for example from an epoxy compound. Work on the construction of the product is carried out in the following way. The bearing bottom of reinforced concrete is erected on a previously prepared base with the device of all necessary intermediate layers (for example, preparatory, anticorrosion, depending on the specific conditions). etc. An insulating layer is applied to the surface of the bottom to prevent prognosis of o through the bottom of oil products. A filtering layer (Lesok, crushed stone) is placed on the top of the insulation layer, a drainage pipe is mounted, and then a steel cladding is laid on top of the drainage system. At. In this case, in steel cladding, the ss s are filled from the periphery to the center of the bottom or from its center to the periphery, and the slope is at the very bottom in all cases of f. The collection is located in the lower part of the bottom. UkJ1OH in the bottom is performed either at the expense of

the construction of the bottom, or for the account-nabetonkn.

Wall cladding, depending on the design of the tank and the methods of its construction, is carried out both before and after the construction of walls. In a tank with prefabricated walls, cladding is laid into the formwork form of the panels during their concreting. With monolithic walls, it can serve as an internal formwork for concreting. In another case, the gap between the cladding and concrete of the walls is provided by various gaskets or lubricants that prevent adhesion of the concrete to the shell.

Facing can be performed. also after the erection of walls. In this case, the gap between the stencil and the cladding is formed during the installation of the cladding. If the steel lining is not sealed, both in the walls / and the bottom (for example / in the place of welds) the oil product enters the drainage system and is discharged from the pesiepByar / does not penetrate into the environment / which prevents the bottom of the insulation from under the drainage system by layer.

The present invention allows to increase the level of reliability of environmental protection from pollution. In addition, if necessary, troubleshooting. the work is dry; It is sufficient to open only the steel lining / without opening the bottom itself / that improves the ex-. reservoir operation and reduces reservoir decommissioning during repair work;
