Architectural and space-planning solutions

The project documentation for the reconstruction of the gas station of the Gazprom Neft company designed: construction of a gas station building with a canopy with the demolition of existing buildings; replacement of fuel dispensers, tank farm, technological and engineering networks; transfer of information signs and replacement of the supply cable. The designed filling station is a complex of buildings and structures designed to receive and deliver (500 fillings per day) 3 grades of gasoline (Ai-92, AI-95, AI-98) and diesel fuel for simultaneously refueling four vehicles, which includes : control room building with a shop and cafe, utility rooms; canopy over the platform of filling islands over 2 fuel-dispensing columns (TRK) of the TOKHEIM company of the Quantium 400T 4 model, and underground fuel tanks (two tanks - double-walled two-section with a volume of 50 m3 (25 + 25); platform for tank trucks (AC) with an emergency tank with a volume of 15 m3; drain well; platform for diesel generator set; temporary parking for 3 cars; garbage bin area; tire inflation post; underground storm water treatment facilities; lightning rods. The designed control room building with a shop and a cafe is a one-story rectangular volume with dimensions in the axes of 15,70 m x 10,70 m and a height of 4,04 m. The main entrance is designed in the center of the trading room with the installation of a sliding door. The building will include administrative and amenity premises, a shop floor with an operator's workplace and a cafe, utility rooms of the shop and a cafe, and engineering rooms. The outer walls of the gas station buildings are designed from three-layer metal "sandwich panels" on a metal frame. Roofing - rolled, with a base of three-layer metal roofing "sandwich panels" on metal structures, with internal drainage. The entrance to the building for visitors is designed along a ramp. Glazed doors - with anti-shock film. The canopy is a “T”-shaped structure with overall dimensions in terms of 18,00 x 8,00 m and a height to the top of building structures h = 5,8 m, under which there are two fuel dispensers and a transitional canopy with dimensions in terms of 9,2 .8,0 x XNUMX m. The structure is designed in a metal frame with building structures sheathed with aluminum composite panels. Roofing - from steel profiled flooring on metal structures. Drainage from the roof of the canopy is organized through drainpipes passing in the lining of the columns. The design documentation provides for unhindered access for people with disabilities and people with limited mobility to the gas station building.

Structural and space-planning solutions

The frame of the gas station building is designed according to a two-span structural scheme. Frame pitch in axles – (5,150+5,400+5,150) m. Frame spans in axles – (3,800+6,900) m. The frame columns are made of steel, made of square pipes measuring 160x5mm in accordance with GOST 30245-2003. The columns on which the canopy rests over the passage to the gas station building are made of steel from square pipes measuring 200x8mm in accordance with GOST 30245-2003. The fastening of all columns to the foundation slab is provided rigid. The roof beams are designed from rolled steel I-beams according to STO ASChM 20-93 and channels according to GOST 8240-97. Coating purlins are taken from rolled steel channels according to GOST 8240-97. The roof beams are fastened to the columns and the girders to the beams are hinged. The covering of the gas station building is designed from steel galvanized profiled sheets H75-750-0,8 in accordance with GOST 24045-94 for metal beams and girders. Fastening sheets of corrugated board to the bearing structures of the coating is provided by self-tapping bolts on all supports in each wave. Between themselves, the sheets are fastened with combined rivets with a pitch of 300 mm. The spatial rigidity and stability of the gas station building are provided by the rigidity of the columns fixed in the foundations, vertical ties, as well as the rigidity of the coating disk. The outer walls of the gas station building are made of hinged insulated panels of the "Sandwich" type, fastened to the frame columns with self-tapping bolts. The load-bearing structures of the gas station building were calculated using the SCAD 11.3 design and computer complex without taking into account the joint action of the “building-foundation-foundation” system. The foundation for the gas station building is designed in the form of a monolithic reinforced concrete slab made of concrete of class B20 in terms of strength, grades W6, F150, 200 mm thick with longitudinal and transverse ribs 600 mm high to support the frame racks. Under the foundation slab, a preparation of 100 mm thick from B10 class concrete is provided Bulk soils under the foundation slab are replaced by a cushion of medium-sized sand, laid with layer-by-layer compaction. For a relative mark of 0,000, the mark of the finished floor of the gas station building is taken, corresponding to the absolute mark of +6,800m in the Baltic system of heights. The canopy over the fuel dispensers and the transition to the gas station building is designed according to the frame structural scheme and is supported by the bases of the columns on the metal portals of the fuel tanks, welded to the embedded parts of the foundation slabs. The canopy frame columns above the fuel dispensers are made of steel, made of square pipes measuring 250x8 in accordance with GOST 30245-2003, on which the coating of I-beams is pivotally supported according to STO ASChM 20-93 and purlins of steel rolled channels in accordance with GOST 8240-97, combined with steel galvanized profiled sheets H75-750-0,8 according to GOST 24045-94. Fastening sheets of corrugated board to the purlins is provided by self-tapping screws in each wave. Between themselves, the sheets are fastened with combined rivets with a pitch of 300 mm. The spatial rigidity and stability of the canopy are provided by the rigidity of the columns fixed in the foundations, the hard disk of the roof, as well as the fastening of the roof beams to the columns of the gas station building. The calculation of the load-bearing structures of the canopy was performed using the SCAD 11.3 design and computer complex without taking into account the joint action of the “structure-foundation-foundation” system. The foundations for the portals of the fuel tanks are designed in the form of monolithic reinforced concrete slabs made of concrete of class B20 in terms of strength, grades W6 in terms of water resistance and F150 in terms of frost resistance. Under the foundation slabs, a cushion of medium-sized sand is provided, laid with layer-by-layer compaction. In accordance with the "Technical report on engineering and geological surveys for the construction of a gas station ...", made by LenTISIZ CJSC in 2010, code 245-10 archive No. 11353, the base of the sand cushion under the foundation slab of the gas station building is layered, light loam , silty, soft-plastic, light brown, with interlayers of water-saturated sands, with single gravel, with rare ferruginous spots, with the following characteristics (IGE-2): ρII=1,95 g/cm3, e=0,778, IL=0,62, φII=17°, cII=0,020MPa, E=8,0MPa. In accordance with the Technological report on engineering and geological surveys, the basis for sand preparation under the foundation slabs of the portals of fuel tanks are light, silty, soft-plastic loams, with layers of hard-plastic, gray, with gravel and pebbles 10-15%, with lenses and nests of sands saturated with water , with the following characteristics (IGE-4): ρII=2,07 g/cm3, e=0,576, IL=0,54, φII=21°, cII=28 kPa, E=11,0 MPa. The normative depth of seasonal freezing of bulk soils is 1,14 m. Underground waters for the period of surveys were opened at a depth of 0,5 m. This level is close to the maximum. Groundwater is not aggressive to all brands of concrete in terms of water resistance.
