The object of temporary construction is a single-level contactless car wash with dimensions in the axes of 35.30 by 6.00 m. Roof: flat. The car wash building has a rectangular shape with an elevation of 4.450 m (below the advertising banner). The height in the technical room is 3 m. 0.000 located: 6 stations for washing cars (separated by PVC banners with maintenance instructions) a container with equipment (made according to a standard design, consisting of a complete set of equipment on a single rack with connection of a water treatment station, a washing station and a two-speed heater) a container for technical personnel , 2 parking spaces with a vacuum cleaner.

Constructive decisions.

The project adopted a monolithic slab foundation made of concrete B 22.5, M 6, P150, arranged on a densely compacted sand and gravel base. For a relative mark of ±0.000, the mark of the top of the reinforced concrete was taken. slabs Ground bindings see master plan. Waterproofing - vertical (all surfaces in contact with the ground - coating with liquid penetron or hot bitumen for 2 times). Backfill the sinuses of the pit with medium-grained sand, followed by thrombus from the coefficient. compaction Ku = 0.95 (from natural density). Reinforcement of the foundation slab and slabs is carried out with meshes of individual reinforcing bars 0 12, 16 A-Sh with a step of 150 mm in both directions. Grids are installed in the upper and lower zones of the foundation slab. Reinforcing bars are combined into a mesh using a knitting wire. Overlapping of reinforcing bars should be performed in divergence with a long overlap of at least 34 0 of the reinforcing bar. The production of formwork, reinforcement and concrete work is carried out in accordance with the requirements of SNiP 3.03.01-87. Excavation and concrete work in the winter period should be carried out in accordance with the requirements of SNiP 3.03.01-87, taking into account the following requirements: exclude freezing of the soil by blocking (one blocking is equal to one shift), after which cover the work site with a layer of insulation (insulating fill or mother). up to air temperature = -10 ° С, concreting should be carried out with concrete with antifreeze additives and electrical heating should be carried out. Earthworks will be carried out in accordance with the requirements of TSN 50-302-96. Backfilling should be carried out with compacted sand with water pouring every 300 mm.

Water supply and drainage.

Water supply and replenishment of irretrievable water losses of a typical contactless car wash is carried out from intramaidan water supply networks. The connection point is the pipeline for supplying cold water to the DHW system in AITP. At the connection point, a water consumption meter with a pulse output is installed, weld-in ball valves are designed. The laying of water pipes along the AITP is made of galvanized steel pipe; to prevent the formation of condensate, thermal insulation from the K-FLEX ST material is designed from the tie-in point to the exit of the pipes into the ground. Further, through pipelines mounted from pressure polyethylene pipes Isoproflex-Arctic 50/110, located in the soil below the freezing depth, water is supplied to the technological room - the car wash container. Taking into account modern requirements and technologies, the project provides for the recycling water supply of the self-service car wash. Contaminated process water after use enters the receiving trays-wells and then by gravity separate discharge through pipelines mounted from corrugated two-layer pipes Ikaplast Du160 mm, is fed into the Flotenk-settler-sand trap, where particles of large fractions are deposited. Further, the clarified effluents enter the Flotenk unit, where they undergo complex treatment. The Flotenk block is a tank that includes a gasoline oil separator, an aeration system and a storage tank, made in one housing. The treatment plant uses a method based on the ability of microorganisms to use many organic and some inorganic compounds contained in wastewater as a nutrient. Deep biological treatment allows you to remove a variety of organic compounds, including toxic ones, from wastewater. Oil-petrol oil separator - with a capacity of 6 l / s, coalescent modules are installed on it, from which free, as well as partially mechanically emulsified oil products are released from wastewater. The advantage of modules is that modules are self-cleaning. When flowing, water creates vibrations, i.e. the modules vibrate, thereby contributing to the floating of oil particles and the settling of particles of suspended solids. The oil-petrol separator is equipped with a signaling sensor that controls the thickness of the oil layer that has surfaced. When the limit oil volume is reached, an alarm is activated that allows the separator to be emptied in a timely manner. Maintenance of the modules is carried out by removing them and washing them with a jet of water, followed by installation in their seats at least once every three years. Removal of the oil film, after the level sensor is triggered, is carried out by pumping out the sewage truck with subsequent removal to a special landfill. fine flotation filter, filled with NES hydrophobic sorbent. The sorbent is a composite material based on natural aluminosilicates. It has a number of advantages in comparison with the sorbent widely used for these purposes based on activated carbon. It allows: to operate treatment facilities without replacing the sorption load for up to 3 years, to ensure a high level of cleaning throughout the entire period of operation. Purification degree: for suspended solids (sv) – up to 20 mg/l; for oil products - up to 0,3 mg/l. After treatment, the treated effluents are discharged by gravity into the existing well of the intramaidan storm sewer networks. If necessary, the treated effluent undergoes additional treatment at the TVT unit located in the premises of the technical staff unit (see Fig. VC). The unit (symbol TVT) is designed for post-treatment of car wash wastewater and subsequent discharge of the leachate (depending on the results of water analysis) into the sewer or return pipeline for supplying water to the car wash. The modules of the TVT installation contain replaceable filter cartridges manufactured by Geyser LLC. At present, only the Geyser company has the technology for mass production of these materials. PGS polymers are fundamentally new materials that combine three filtration methods at once: mechanical, sorption and ion-exchange. None of the existing materials provides cleaning for such a wide range of chemical compounds as PGS polymers, microglobules have a large inner surface (up to 500 m2/g). The surface of the microglobule itself is covered with active groups on which ion exchange occurs. The escaping ions directly interact with the chemically active surface of the polymer, bypassing the stage of diffusion into the depth of the granule, which is traditional for ion-exchange resins. As a result, the volumetric filtration rate of PGS polymers is 10-20 times higher than that of conventional granular ion-exchange resins. This is an important advantage of UCG polymers. Removal of mechanical impurities preferably takes place in the surface layers of the polymer. The size of the time can be anything in the spectrum: 0.01-3.5 µm. By changing the synthesis conditions, it is possible to obtain the required porosity of the material with a spread of no more than 10%. At present, Geyser has studied and developed technologies for the production of more than 30 modifications of PGS polymers. Materials with both cation-exchange and anion-exchange properties have been obtained. For the complex removal of harmful impurities from water, the best performance is for a polymer based on resorcinol - "ARAGON". Mechanical filtration of all particles larger than the dimensions of the outer pores of the material occurs on the surface. The filtration channel has a complex tortuous shape with a gradient porosity. This makes it impossible to discharge filtered harmful impurities into purified water, which often happens during pressure surges. The number of free channels in the material gradually decreases, reducing the pressure of purified water. The filter element based on the "ARAGON" material can be used repeatedly. With the beginning of filtration, the EMC for supplying raw water to the HWT opens, the servomotor opens the ball valve on the filtrate supply line, and water from the mixing tank is supplied by a pump to the middle and upper dirty water collectors, interconnected by a jumper with an air vent. From the collectors, water under constant pressure (to be specified during debugging tests) is supplied through connecting pipelines to the cavities of the filtration cartridge modules. In modules water passes "outside-inside" replaceable cartridges. The entire volume of dirty water supplied on the cartridge is filtered through them. All contaminants are collected on the surface or volume of the cartridges, forming a layer of deposits. Subsequently, the thickness of this layer increases and, as a result, the filtrate flow decreases. After a significant increase in resistance and, as a result, an increase in the pressure drop at the inlet and outlet of the HPT installation, the filtration process decreases or stops. The performance and resource of the cartridges depend on the content of contaminants in the water. Pure water (filtrate) through the internal cavity of the cartridges enters the lower manifold, from where it is fed through the rotameter (water meter) and the ball valve with an electric drive under the pressure of the installation pumps into the pressure absorber well and then by gravity through the control well into the existing well. The project also provides for a wash water circulation pipeline that supplies purified process water to the car wash equipment in a constant circulation cycle, which prevents stagnation and icing at sub-zero temperatures. All reinforced concrete structures and parts are subject to waterproofing. Before starting earthworks, it is necessary to call representatives of the operating organizations of underground engineering networks and structures to clarify the locations of networks on the ground. The project provides for water supply to the self-service car wash from intramaidan water supply networks with the equipment of a water consumption metering unit in the AITP building. Stationary self-service car wash is a fully automated, publicly available equipment supplied in a single container unit and used for car washing. The management of the washing process and the dosage of detergents and conservation, water heating, payment calculation and implementation of the programs selected using the buttons is carried out by an industrial computer. The main unit in the equipment is a high-pressure pump that creates a working water pressure of 30 to 120 bar. The pump is driven by a three-phase voltage electric motor. Water with detergents is supplied under high pressure through a high-pressure hose system with outward washing and through a spear or brush to the surface of the car. Car washing is done quickly and efficiently. The high-pressure fitting at the end of the spike forms a jet of water in the form of a spatula. Washing efficiency is enhanced by a low-pressure stainless steel boiler for hot water. The water used for washing is improved by softening and cleaning in the water recycling process. Improvement of water is carried out when cleaning from mechanical impurities and minerals. Thanks to this, the effectiveness of the action of chemicals increases, and the surface of the washed car after drying does not leave stains and streaks. Chemicals used in cleaning are dosed under computer control and using dosing pumps or injectors, which guarantees their economical consumption and gives the expected washing effect. The use of products recommended by the company guarantees high quality of services and accurate operation of the equipment. The equipment is equipped with an anti-freeze system. It works on the principle of forced water circulation. When the ambient temperature drops below 3ºC, a thermostat placed outside the sink will turn on the anti-freeze system, which prevents the water inside the piping system from freezing. In the premises of the block of technical personnel, the project provides for the placement of an additional wastewater treatment plant for wastewater treatment of waste water from Geyzer LLC, which operates in conjunction with external treatment facilities. The removal of process waste from the washing equipment is provided for by gravity pipelines, mounted from HDPE sewer pipes, laid in the thickness of the floor and further to the OS. After treatment, the treated effluents are discharged by gravity into the existing well of the intramaidan storm sewer networks.

Heating, ventilation and air conditioning.

The project provides for the heat supply of the sink from the boiler unit located in the technical compartment of the sink (supplied with a block of heating equipment in the technological container). The coolant is antifreeze. The heating system is combined. The room of the technical module is heated by an electric heater with a power of 1,5 kW, which maintains the internal temperature in the room within +5ºС. The room for technical personnel is heated by two electric heaters with a total power of 3 kW, maintaining the internal temperature of the room within +18ºС. In the washing compartments, an underfloor heating system is designed to provide a comfortable car wash, which prevents the possibility of icing and ice formation. Air is released from the heating system at the highest points of the system (on the underfloor heating collector) using automatic air vents. Pipelines of the heating system are laid with a slope of at least 0,002. Ventilation of the premises of the technical module and personnel is natural. The premises are equipped with ventilation openings equipped with adjustable grilles. All work on the manufacture and installation of heating systems must be carried out in accordance with the requirements of SNiP 3.05.01-85. The design parameters of the outside air are taken in accordance with Appendix 8 of SNiP 2.04.05-91 for parameters "A": Parameters "A". Warm period of the year: outdoor temperature tн = 20,6°C; specific enthalpy J = 48,1 kJ/kg. Parameters "B". Cold period of the year: outdoor temperature tн = - 26C; specific enthalpy J = – 25,3 kJ/kg. The specified parameters are provided in accordance with the requirements of SNiP 2.08.02-89*, SNiP 2.04.05-91 with a normally operating heating system and proper operation of the equipment.
