Architectural and space-planning solutions

The station for checking the technical condition of vehicles is designed to carry out technical inspection of cars and trucks (diagnostics of vehicle parameters that affect traffic safety). The station building is designed as a 3-storey one, with a basement, without an attic, with a roof gas boiler house. The main entrances to the building and entry / exit of cars are provided from the street, as well as from the territory adjacent to the designed building. In the basement floor, engineering and technical service rooms, amenity rooms, and an archive room are designed. On the ground floor there is a diagnostic room, administrative premises with a hall for customers who draw up technical inspection documentation. Service rooms are designed on the second and third floors: sanitary facilities - dressing rooms with lockers for outdoor, home and work clothes, bathrooms, showers, dining rooms, offices. On the roof, a ventilation chamber and a roof gas boiler room are provided. The building has two evacuation stairwells of L1 type and an external metal evacuation staircase. Exterior finish of the building: Socle - facing with natural stone. Walls - cladding with Alucobond composite panels. Roof - with roll coating (PVC-membrane), with an internal drain, partially exploited (passage area to the boiler room). The project documentation provides for the accessibility of the first floor with a reception area for disabled visitors.

Structural and space-planning solutions:

The level of responsibility of the building is normal. The building is designed in a steel frame with ceilings made of prefabricated reinforced concrete hollow flooring. Frame - three-story four-span frame-link. Columns and frame beams - from rolled profiles. Rigidity and stability of the frame is ensured by rigid pinching of the columns into the foundations, frame nodes of the frame in the transverse direction, in the longitudinal direction - by vertical ties, a hard disk of the cover. Structural analysis was performed using the SCAD 11.3 software package. The foundation of the building is monolithic reinforced concrete slabs 500 mm thick with different bottom marks: minus 3,650 - in the part of the building where the basement is located; minus 2,430 - in the non-basement part of the building. At the base of the slabs - dense sands of medium size with design characteristics ρ = 2,07 t/m3, φ = 38°, c = 0,02 kgf/cm2, E = 400 kgf/cm2; silty sands ρ = 2,00 t/m3, φ = 34°, c = 0,02 kgf/cm2, E = 250 kgf/cm2. Bulk soils that fall into the base of the foundations are removed and replaced with a cushion of medium-density sand. The estimated settlement of the building is less than 1 cm, the depth of the compressible thickness is 9,0 m. The walls of the basement are monolithic reinforced concrete with a thickness of 400 mm. Construction material - class B25, W6 concrete; F100, class AIII fittings. Basement waterproofing from groundwater: the use of high-grade concrete for water resistance W6; installation of pasting waterproofing of a closed basement contour, the use of waterproofing gaskets in the working seams of concreting. The relative elevation of 0,000 corresponds to the absolute elevation of 19,600 m.

Boiler rooms. For heat supply of heating systems and hot water supply of the station for checking the technical condition of transport, a block-modular automated gas roof boiler house was designed. The dimensions of the block-modular boiler house are 6,00x4,00,x2,60. According to the degree of explosion and fire hazard and fire resistance, the boiler room belongs to the category "G" and "II". The installed capacity of the boiler house is 400 kW. As easy-to-reset structures, at the rate of 0,03 m2 per 1 m3 of the volume of the boiler room, a part of the easy-to-reset roof with an area of ​​1,9 sq.m is provided. Heat consumers belong to the second category in terms of heat supply reliability. Viessmann closed-chamber hot water boilers were accepted for installation - two Vitoplex 200 SX2 hot water boilers, 200 kW each, with 2-stage gas burners GP-26.10H from Oilon. The estimated heat output of the boiler house, taking into account losses in the networks and the boiler house's own needs, will be 348 kW, including: for heating - 152 kW; for ventilation - 116 kW; for hot water supply - 54 kW; for losses in heat networks and own needs of the boiler house - 26 kW. The main type of fuel is natural gas QpН = 8000 kJ/m3. The operating mode of the boiler house is year-round. The scheme for connecting heat networks intended for transporting the coolant to the heating and heat supply systems for heaters is independent (dependent), two-pipe, hot water pipelines - independent closed, through heat exchangers (dependent). It is planned to control the temperature of the coolant depending on the outside air temperature. Regulation of the boilers and maintaining the necessary parameters of the coolant is provided by the automation of the boiler room. The heating system is closed, two-pipe. The operation of the boiler room is in automatic mode, without the constant presence of service personnel. The water temperature at the outlet of the boilers is 85°C. The heat carrier at the outlet of the boiler room is water with a temperature of 80 ° C (for heating systems), and with a temperature of 65 ° C (for hot water systems). Preparation of hot water for DHW - in the consumer's ITP For the preparation of hot water for the needs of heating, ventilation and DHW systems, it is planned to install two plate heat exchangers from the Ridan company with a rated power of 200 kW each. The following pumping equipment is accepted for the installation: to ensure the circulation of the heat carrier of the boiler circuit, each Vitoplex 200 SX2 boiler is equipped with a Wilo boiler pump of the TOP-S 50/7 brand; to ensure the circulation of hot water in the heating system of the boiler room, a circulation pump manufactured by "Wilo" brand "Star-RS 15/4-130" is provided. in the event of a decrease in tap water pressure, a Wilo pump of the MHI 203-3 brand (1 pc.) was installed. Initial filling of the heat supply system - chemically treated water - from the tank. Periodic replenishment of the system is provided directly from the water supply through the pressure regulator downstream, maintaining a static pressure not higher than 6 bar.
