Abstract

FIELD: construction engineering. SUBSTANCE: this is intended for storing evaporating petroleum products such as gasoline primarily at gas-filling stations. Storage is provided with guarding in the form of 0.5 m thick walls having roofing. Installed on foundations inside walling are reservoirs for petroleum products. Also provided is compartment for location of pumps which are connected with reservoirs by pipelines through system of valves. Storage incorporates water-proofed vessel located inside walling or outside it below ground water level and connected by piping with sumps installed under each storage reservoir. Reservoirs are installed in sumps through supports and create space with them. Sump spaces are hydraulically interconnected. Aforesaid embodiment of storage simplifies design and simultaneously prevents fouling of environmental medium when gas-filling stations are in operation. EFFECT: higher efficiency. 5 cl, 2 dwg

Description

 The invention relates to construction and can be used to store evaporating oil products, such as gasoline, mainly at gas stations.

 An analogue of the invention is a tank for storing oil and oil products, including a foundation, a tank located below the groundwater level, a building and a roof [2].

 The disadvantage of the design is the great complexity of its manufacture, installation and repair work. In addition, this design does not prevent the loss of oil from evaporation.

 The closest analogue to the proposed one is a petroleum product storage, including tanks installed on the foundation and a waterproofing tank located below the groundwater level, with floating partitions for separating the oil pumped into them and the working agent placed above it. The storage has a roof and pumps for pumping and pumping oil products and working agent through pipelines [1].

 The known design provides fire safety by preventing the evaporation of oil from tanks, however, this is achieved by the complex design of the tanks and, in addition, there is a danger of contamination of the surrounding soil with oil products, since it is impossible to trace the tightness of the tanks and the bottom.

 The objective of the invention is to simplify the design while preventing pollution of the environment, mainly when working at gas stations.

 This problem is solved in the oil product storage, including tanks installed on the foundation, a waterproofing tank located below the groundwater level, a roof and pumps for pumping and pumping oil products from tanks through pipelines due to the fact that the oil product storage is equipped with pallets hydraulically connected under each tank between themselves and the fence installed around the perimeter of the location of the tanks, having a height greater than the value of the location from the ground the upper level of the tanks, and the roof is installed on the fence, the pallets are connected to the waterproofing tank by pipelines, and the cavity between the fence and the tanks and above the tanks above the level of their location is filled with sand.

This problem is also solved due to the fact that:
- a waterproofing tank is located inside the fencing zone;
- waterproofing tank is located outside the fencing area;
- a partition is installed in the fencing zone, forming a compartment for the placement of pumps with the fence;
- the petroleum product storage has partitions installed between the tanks;
- the fence is made in the form of walls or of brick, or concrete, or of blocks.

 In FIG. 1 schematically shows a storage of petroleum products; in FIG. 2 - section aa in figure 1.

 The oil product storage contains tanks 1 mounted on the foundation 2. Under each tank there is a pallet 3, and between its bottom and the bottom of the tanks there are supports 4, due to which a cavity is formed between the tanks and pallets 5. The pallets 3 are hydraulically connected by pipelines 6.

 The petroleum product storage has a waterproofing tank 7 located below the groundwater level and connected by a pipe 8 with pallets 3.

 Waterproofing tank 7 can be located both inside the fencing zone 9 (see figure 1), and outside the specified zone (see figure 2).

 The fence 9 is installed around the perimeter of the location of the tanks 1 and is made in the form of walls or of brick, or concrete, or of blocks.

The thickness of the walls should be at least 0.5 m. The walls of the fence 9 have a height of H ₁ , the value of which is greater than the value of the upper level H _{2 of the} location of the tanks 1, i.e. H ₁ > H ₂ (figure 1).

 The fence 9 has a roof in the form of a light corrugated roof 10, and inside the fence there is a partition 11, forming a compartment 12 inside the fence zone for accommodating pumps 13 for pumping and pumping oil from reservoirs 1 through pipelines 14. The direction of the oil product into a specific tank is regulated by valves 15 .

 The cavity between and above the tanks, as well as between the tanks and the fence is filled with sand 16.

 Between the tank 1 can be installed partitions 17. The fence 9 in the upper part above the level of location of the sand 16 has ventilation holes 18.

 The cavities of the tanks 1 in the upper part are connected to the atmosphere through taps 19.

 Filling the tanks 1 with oil products, for example gasoline, is carried out by pumps 13. In the process of storing oil products in tanks 1, in case of leakage, the oil enters the pallets 3 and then flows into the waterproofing tank 7, since the pallets 3 are connected by pipelines 6 to each other and to a pipeline 8 with waterproofing 7. The waterproofing tank 7 has a hatch in the upper part (not shown in Fig.), through which it is possible to control the appearance and accumulation of petroleum products and ensure its immediate weaver. The volume of the waterproofing tank 7 ensures the reception of the spilled oil from the largest of the tanks in the event of an accident and does not allow the spill of oil into the surrounding soil. The fence 9 and the partition 11 are a fire wall of the 1st type.

 Due to the presence of sand 16, the accumulation of gasoline vapors in the gas storage room is prevented, which ensures explosion safety.
