Architectural and space-planning solutions

The building of the catering workshop for servicing high-speed trains is rectangular in plan, 94,50 x 70,45 m in size, has a basement floor, 2 above-ground floors. In the basement floor, 2,70 m high, there are amenity rooms for personnel (cloakrooms, showers, bathrooms, etc.), rooms for engineering equipment. On the ground floor with a height of 4,80 m, a complex of industrial premises, a room for loading raw materials and shipping finished products, located at the ends of the building, and sanitary facilities were designed. On the second floor with a height of 3,30 m, administrative and service premises, a canteen complex for staff were designed. On the roof there are superstructures with rooms for accommodating ventilation equipment and exits to the roof. To ensure technological connection between floors and evacuation, two stairwells L1 and two stairwells H2 with access to the street, a passenger elevator with a capacity of 630 kg, and two freight elevators with a capacity of 1000 kg are provided. For access to the technical premises of the basement, isolated entrances from the street are provided. The roof is flat, combined with an internal organized drain. Exits to the roof are provided from the volumes of stairwells. Filling of window openings - metal-plastic window blocks with double-glazed windows, stained-glass windows. Facade finishing: socle - facing solid brick; walls of above-ground floors - wall three-layer panels with an inner layer of insulation and a coating of metal profiled sheet, attached to the frame of the building. Partitions - depending on the functional purpose of the premises - from aerated concrete blocks, in rooms with a wet regime and technical rooms - brick. Interior decoration is carried out in accordance with the functional purpose of the premises. The building of the checkpoint is one-story, without a basement, with a plan size of 9,0 x 6,0 m with security premises located in it, a bathroom, a water metering unit. External walls - brick with external insulation made of MPV with plastering and painting with facade paints. The roof is flat combined.

Structural and space-planning solutions

The building was designed according to the frame-bonded scheme. The spatial rigidity and stability of the building are ensured by the joint work of columns, hard disks of floors and stiffening diaphragms, divided by a temperature-strain joint into two blocks. Level of responsibility II. Relative elev. 0.000 corresponds to 14,7. Columns - monolithic reinforced concrete with a section of 400 x 400 mm, concrete B25, class AIII reinforcement. Overlappings - monolithic reinforced concrete without crossbars 250 mm thick, concrete B25, class AIII reinforcement. Walls (diaphragms) - monolithic reinforced concrete 200 mm thick. Basement walls - monolithic reinforced concrete 200 mm thick, concrete B25, W6, F100, class AIII reinforcement. Fastening of wall sandwich panels 150 mm thick is carried out to the columns, in the openings - metal fachwerk. Foundations - monolithic reinforced concrete grillages on piles. Piles - prefabricated reinforced concrete S180-35S, consisting of S120.35VS and S60-35NS, according to series 1.011.0-v.8. The joints of the piles are protected by a bitumen-polymer coating. Seal of piles in the grillage is hard. The design load on the pile - 100 tf was adopted on the basis of the report "Statika Engineering" inv. No. 1510 issue. In 2008. Grills - columnar 600-750 mm thick, concrete B25, W6, F100. The basement floor slab freely rests on the grillage. Technical report on engineering and geological surveys for the development of working documentation for the construction of a catering workshop for servicing high-speed trains. The maximum position of the groundwater level with a free surface should be expected during periods of heavy precipitation and snowmelt at abs. mark ~ 13,0 - 12,5 m. After carrying out planning work on the territory, a change in the groundwater regime is possible. Pressure waters were encountered at depths of 15,5 - 18,2 m, the pressure in wells No. 9787 and 9788 was 6,7 - 8,3 m. According to the results of chemical analyzes in accordance with SNiP 2.03.11-85, in relation to concrete of normal permeability, groundwater exhibits a low degree of aggressiveness in terms of the content of aggressive carbon dioxide, pressure waters are slightly aggressive (in well No. 9788 - moderately aggressive) in terms of the content of aggressive carbon dioxide and hydrogen indicator. Soils in most of the territory are non-aggressive, in the area of ​​well No. 9787 they are slightly aggressive. In relation to steel, soils are characterized by high corrosive aggressiveness. Expected draft 2,0 cm. Calculations are made in SCAD 7.31R2 The designed checkpoint building is one-storey. Walls - brick 250 mm thick, brick M100, F50 on the CPR M100. Coating - monolithic reinforced concrete slab 200 mm thick, concrete B 25, class AIII reinforcement. Foundations - monolithic reinforced concrete tape on a natural basis; sole width - 850 mm, concrete B25, W6, F100, class AIII reinforcement. The design soil resistance of the base is 1,5 kg/cm2, the design pressure is 0,82 kg/cm2. The basis for the structures of external heat supply networks are fluid-plastic loams R = 0,587 kg/cm2. The average pressure on the base does not exceed 0,3 kg/cm2. Maximum pressure 0,651 kg/cm2. Under the supports of external networks, monolithic and prefabricated (FBS) reinforced concrete foundations are designed on a natural basis. Foundation concrete B25, W6, F100. Driveways under the networks are organized by the installation of lattice racks and trusses with a span of up to 20 m from a corner in accordance with GOST 8509-93.
