Architectural and space-planning solutions

The project documentation provides for the construction of a stationary filling station with an operator building and a canopy over fuel dispensers (TRK). The control room building is one-story, rectangular in plan, with dimensions in the extreme axes of 17,33 x 10,62 m. The height from ground level to the top of the parapet is 4,34 m. The height of the premises to the bottom of the suspended ceilings is 3,0 m. The level of the finished floor corresponding to the absolute mark of 0,000 is taken as a relative mark of 18.00. At the level of 0,000, the following are designed: a service room for drivers and passengers, amenity room for operators, a utility room for a fast food corner, a store for related products, a room for receiving, storing and preparing food for sale, a low-temperature chamber, a medium-temperature chamber, a room for receiving, storing and preparation of non-food products for sale, ITAT and ITSO maintenance room, amenity room for refuellers, as well as a room for household equipment and PPSh, bathrooms, a water metering unit, a room for cleaning equipment. The height of the premises to the bottom of the protruding structures is 2,7, 2,5 m. The covering (roof) of the control room is flat on the "sandwich"-panels "Petropanel" with an internal drain and electric heating of the funnel. Roofing - rolled (Technoelast "Flame-Stop"). Wall fencing of the building - three-layer sandwich panels 150 mm thick on a steel frame. Finishing - facing with aluminum panels with a polymer coating. Partitions - frame-sheathed on a metal frame with a heat and sound insulating layer of mineral wool materials, including fireproof ones with a fire resistance limit of EI45 100 mm thick. The interior decoration of the premises and the floors are designed in accordance with the purpose of the premises: floors - ceramic tiles; walls and partitions - pasting with glass wallpaper followed by painting, ceramic tiles; ceilings - suspended type "Armstrong", drywall, type "Grilyato"; Facade stained-glass window and windows - aluminum frame filled with two-chamber double-glazed windows with anti-shock film. The canopy over the fuel dispensers (TRK) is a frame-type structure, “T”-shaped in plan with dimensions of 8,0 x 22,0 m and 8,0 x 13,9 m. The height from ground level to the top of the roof is 5,52 m. The location of the fuel dispenser is between the columns. Covering (roof) - flat on metal structures. Roof - profiled steel sheet. Downspouts are designed inside three columns supporting the canopy and are completed with a full height electrical heating system. Suspended ceiling - metal sheet with a polymer coating. Columns of circular cross section - unlined, powder coated. The sides of the dispenser islands are made of stainless steel. Measures are envisaged to ensure the accessibility of the building and structures for people with limited mobility (MGN). The height of the side stone at the intersection of the blind area with the carriageway does not exceed 4 cm. The longitudinal slope of roads and pedestrian walkways does not exceed 5%. The evacuation entrance and exit to the service building is equipped with a ramp. The coating is hard, non-slip. Doorways do not have thresholds. The width of the door panels is assumed to be at least 0,9 m.

 Structural and space-planning solutions

 The control room and shed buildings are designed in a steel frame. Level of responsibility – II. The constructive scheme of the control room building is a complete frame. The node supporting the roof beams on the columns is hinged. The spatial immutability of the frame of the control room is ensured by the joint work of the columns, rigidly fixed in the foundation, and the bonded disk of the cover. The sections of the main load-bearing structures of the frame were adopted: columns - square pipes according to GOST 30245-2003 from steel C255; covering beams - I-beam according to STO ASCHM 20-93 from steel C255, covering corrugated board - H75-750-0.8 according to GOST 24045-94. As external enclosing walls, hinged wall panels of the "Sandwich" type 150 mm thick are used, the coating is corrugated board, laid directly on the upper belts of the coating runs. A fachwerk system has been developed for fixing wall panels. The foundation for the control room building is a non-buried monolithic reinforced concrete slab 300 mm thick made of B25, W6, F150 class concrete. To prevent freezing of the base of the foundation slab, it is provided for its insulation with plates of extruded polystyrene foam. An artificial base is arranged under the foundation slab. In accordance with the report on engineering and geological surveys, the base is the EGE-1 layer (light silty loam, grayish-brown weathered, ferruginous, with sand interlayers, semi-solid), which has the following characteristics: ρн=2,02 t/m3; e=0,650; n=23o; Сn=0,25 kg/cm2; E=130 kg/cm2. The average pressure under the sole of the foundation slab is 0,22 kg/cm2. The design soil resistance of the base is 2,92 kg/cm2. The expected settlement of the foundation slab is 1,0 cm. The spatial invariability of the canopy frame is ensured by the joint operation of the columns, rigidly fixed to the foundation, and the bonded disk. The node for supporting the main beams of the roof on the columns is hinged. Columns - square pipes according to GOST 30245-2003 from steel C255, canopy beams are designed from I-beams according to STO ASChM 20-93 from steel C255, corrugated board - H75-750-0.8 according to GOST 24045-94. The foundations for the canopy columns are monolithic reinforced concrete, made of B25, W6, F150 class concrete. In accordance with the report on engineering and geological surveys, the base is the EGE-1 layer. The average pressure under the base of the foundation is 0,88 kg/cm2, the design soil resistance of the base is 2,92 kg/cm2. The expected settlement is 4,0 cm, the maximum horizontal displacement is 2,9 cm. The foundations of underground tanks are taken on a natural basis in the form of a monolithic reinforced concrete slab 400 mm thick, concrete class B25, W6, F75. The basis for the foundations for the tanks is the EGE-2 layer (light silty gray loam, with sand nests, with sand lenses, with gravel, soft-plastic), which has the following characteristics: ρн=2.03 t/m3; e=0.664; n=19o; Сn=0.21 kg/cm2; E=100 kg/cm2. The design of the foundations provides stability against ascent. Coating waterproofing of the outer faces of the foundations in contact with the ground is provided. The calculation of the main load-bearing structures was performed using the SCAD software package version R11.3. The displacements and deflections obtained as a result of the spatial calculation of the building frame do not exceed the maximum allowable values. The relative mark of 0,000 corresponds to the absolute mark of 18.00. The maximum level of groundwater is expected during periods of snowmelt and heavy rains on the surface of the earth, at absolute levels of 16.00 - 16.50.
