Architectural solutions

The fuel dispensing complex is designed for refueling cars with three grades of gasoline (AI-92, AI-95, AI-98) in automatic mode and includes the following buildings and structures: service block building; platforms for 4 fuel dispensers with a canopy; ground heat-insulated tanks for fuel; overpass under the fuel line with a filling console of the lower filling; container yard; advertising installation; flagpoles. The building of the service block is one-story, rectangular in plan, with dimensions in the axes of 6,40 x 2,90 m, and a height of 3,47 m to the top of the parapet. A service room and a bathroom are designed in the building. External enclosing structures - wall and roof three-layer panels with an inner layer of insulation and a coating of metal profiled sheet, attached to the metal frame of the building, installed on the foundation slab. Canopy over fuel dispensers - rectangular in plan, dimensions 54,00 x 7,50 m, height 5,50 m - made of a metal frame coated and lined with painted metal profiled sheet. Ground fuel tanks are prefabricated tanks, thermally insulated and lined with aluminum hinged panels.

 Structural and space-planning solutions

 Service block building; the canopy over the filling islands, the overpass for the fuel line, the ground fuel tanks and their fencing are designed in steel structures. Steel structures are manufactured by the PNSK Production Association. The service block is a prefabricated modular building, consisting of a steel frame with external walls and sandwich panels. The building - complete factory assembly, is delivered to the construction site in finished form and installed on the foundation slab. The 54,0 m long canopy consists of six Standard 6 modules. The constructive scheme of the module is a spatial structure measuring 9,0 x 7,5 x 0,9 m, consisting of a column and trusses of a mutually perpendicular direction. The longitudinal frame is a T-shaped structure: a two-console truss with a cantilever outreach of 4,5 m, rests on a column 4,6 m high. The columns consist of two channels connected by planks. Farms of the transverse direction - cantilevered, fixed in pairs to the longitudinal farm. Along the perimeter of the module, the longitudinal frame truss and transverse trusses are combined into a spatial system by perimeter trusses. Trusses are designed from closed bent-welded and rolled profiles. Covering of the canopy - steel profiled flooring. The rigidity of the coating disc is ensured by frequent fastening of the steel corrugated board to the steel girders with self-tapping bolts, and by connecting the corrugated board sheets together with combined rivets. The stability of the module is ensured by embedding the columns in the foundations, a spatial system of trusses with rigid junctions, and a hard disk of the cover. The calculation of load-bearing steel structures was performed using the SCAD software package. Fuel tanks - ground, thermally insulated, with a fence made of hinged aluminum composite panels on a steel frame. The foundations of the structures are designed from monolithic reinforced concrete on a natural basis in accordance with engineering and geological surveys carried out at the construction site. The foundation of the service block is a shallow slab 300 mm thick. Protection against freezing of soils at the base of the slab is provided. The foundations for the columns of the canopy are free-standing columnar foundations with anchor bolts for attaching the columns; the depth of foundations is below the depth of soil freezing. The foundations for fuel tanks are 300 mm thick slabs with embedded parts for fixing the tanks. Under all the foundations, the project provides for the installation of a cushion of medium-grained sand with compaction up to sk = 1,65 t / m3 with a thickness of 0.50 to 1,0 m. The foundation material is B15 class concrete, class AIII reinforcement. Groundwater during the survey period was recorded at a depth of 1,5 - 2,0 m from the earth's surface. Groundwater is not aggressive towards concrete of normal permeability. A relative elevation of 0,000 corresponds to an absolute elevation of 2,950 m.
