Architectural and space-planning solutions

The designed filling station is a complex of buildings and structures designed to receive and dispense (500 fillings per day) 3 grades of gasoline (Ai-92, AI-95, AI-98) and diesel fuel, for refueling six vehicles at the same time. The complex includes: a control room building with a shop, bistro cafe and utility rooms; canopy over the platform of filling islands for 3 fuel dispensers (TRK) with underground fuel storage tanks - single-chamber volume 50 m3, single-chamber volume 40 m3, and two double-chamber 30 m3 each; platform for tankers (AC); underground storm water treatment facilities; a platform for placing a diesel generator set for backup power supply of filling stations; transformer site; temporary parking for 6 cars; garbage collection area; cabinet "water / air"; drain wells; lightning rods; flagpoles; information board. The building of the control room with a shop and a cafe-bistro is one-storey, "L" shaped in plan, with dimensions in the axes of 23,60 x 8,68 m and 4,09 x 2,79 m and a height 4,30 m. The main entrance is designed in stained-glass windows with the installation of a metal-plastic sliding glass door. The building will include administrative and amenity premises, a trading floor of a store with an operator's station and a cafe-bistro, utility rooms of the store and a cafe, and engineering premises. The outer walls are designed from non-combustible metal facade panels with a polymer coating. The roof is flat, made of rolled materials, with a base of three-layer metal roofing "sandwich panels" on steel structures, with external drainage. The entrance to the building for visitors is designed along a ramp. The lower part of the entrance glazed doors to a height of 0,3 m is protected by a shockproof strip. A canopy is a complex structure with overall dimensions 12,60 x 27,70 m and 12,60 x 41,30 m and a height of 5,70 m to the top of the building structures. The structure is designed in a steel frame with the building structures sheathed with metal panels. Roofing - from steel profiled flooring on metal structures. Drainage from the roof - external organized, through drainpipes passing in the lining of the columns. The project documentation provides for unimpeded access for disabled people and people with limited mobility to the gas station building.

Structural and space-planning solutions

The control room building is designed according to the frame structural scheme. External walls - hinged from three-layer "sandwich" panels, 150 mm thick on a steel frame, with Liberta 200 panels facing. Partitions made of - gypsum boards on a steel frame filled with mineral wool boards. Covering the canopy building - H75-750-0.8 corrugated board, along the beams. The columns are steel. The main column spacing in the control room building is 3,11 x 7,96 m, square pipe columns 140 x 5 (half-timbered posts 100 x 100 x 3), canopy column spacing 7,4 x 9,0 m, square pipe columns 400 x 10 and 200 x 8. Operator room beams - steel, from a rolled profile: I-beams 25B1 according to STO ASChM 20-93 and from channels 16P and 24P. The canopy is designed from steel beams, I-beams 40Sh2, 20B1 according to STO ASCHM 20-93. Roof - rolled with insulation. Structural analysis was performed using the SCAD program, version 11.1, the calculation of foundations was performed using the SNiP formulas. The spatial rigidity and stability of the control room building is ensured by pinching the columns in the foundation in two directions and by the hard disk of the cover. Spatial rigidity and stability of the canopy is ensured by the pinching of the main columns in the foundations and the rigidity of the roof disk. The foundations in the control room building are a monolithic reinforced concrete slab 180 mm thick with a beam (rib) along the contour 650 mm high, the foundations for the canopy columns are columnar from monolithic reinforced concrete. Concrete B20, W4, F150. The thickness of the plate for the tanks is 400mm. Concrete B20, W4, F50. Under the foundation of the control room, a sand cushion 1250 mm thick is provided, under a canopy - 200 mm thick. The relative elevation of 0.000 corresponds to the absolute elevation of +60,150 m. In accordance with the report on engineering and geological surveys of LenTISIZ CJSC (reg. No. 0916/1) of 2010, the base of the foundation is silty plastic sandy loam with the following characteristics  = 25; E = 140 kg/cm2. Design soil resistance of the base R = 1,7 kg/cm2. The maximum pressure under the base of the foundation is p = 0,9 kg/cm2. The maximum groundwater level is near the daylight surface. Groundwater is non-aggressive to concrete of normal permeability. In order to protect the concrete of underground structures, the side surfaces of concrete structures are coated with hot bitumen 2 times. The expected average draft will not exceed 2 cm.

Engineering equipment, utility networks, engineering activities

Water supply, according to the conditions of connection, with an estimated flow rate of 5.62 m3 / day. - one polyethylene inlet with a diameter of 63 mm, a length of 300 m and a laying depth of 1,3-2,05 m with a connection to the water supply of the residential village "Tsvety": Drainage of domestic wastewater, according to the conditions of connection, with an estimated flow rate of 0,96 m3 / day. - three outlets from pipes with a diameter of 110 mm with a total length of 9 m and a laying depth of 1,2 m through the projected domestic sewerage network from pipes with a diameter of 200 mm, with a total length of 90 m, with a laying depth of 1,44 m to 2,53 m, with further flow of wastewater through SPS into the pressure sewer network of PE pipes with a diameter of 63 mm, with a total length of 130 m, laying depth from 1,86 m to 2,02 m, and further along the sewer networks of the residential village "****" to the CSA. Discharge of surface water, according to the conditions of connection, with an estimated flow rate of 11,7 l / s through a storm sewer system made of PP with a diameter of 250 mm with a total length of 131 m with a laying depth of 2,53 to 1,14 m with the installation of local treatment facilities of the Ecoplus company with a capacity 15 l / s and further flow of wastewater through the sewage pumping station into the roadside ditch along the Pulkovo highway. Power supply - with a design load of 70 kVA according to the IIIrd category of reliability, including for heat supply - 27,1 kVA and 5,10 kVA according to the Ist category from reliability with a 0,4 kV cable line from a new transformer substation being built up to Main switchboard of the building using 2 5,1 kVA UPSs. The source of heat supply for heating and ventilation is electricity. Heating in administrative, utility and technical rooms is provided by electric oil radiators. The premises of the trading floor are provided with air heating, combined with supply ventilation. For premises of pantries of food and non-food products - the "warm floor" system with electric heating. Electrically heated air curtains are provided at the entrance doors to the trading floor and to the pantry. Ventilation - supply and exhaust with mechanical stimulation and natural. The air exchange of the premises is taken according to the multiplicity, according to the sanitary standards of the outside air per person, in the trading floor - according to the calculation for providing air heating. A supply and exhaust unit with a rotary heat exchanger was designed. In case of failure of the supply unit, the trading floor does not work. In the bathrooms, shower room, switchboard room, drying cabinet - independent exhaust systems with mechanical stimulation. In order to assimilate heat surpluses during the warm period, in the premises of the trading floor and in the office of the head, air conditioning systems of the split type, with inverter control, are provided. Outdoor units are located on the roof.
