In the swimming hall, bypass paths are provided with access through the foot bath and a special exit for the disabled. On the 3rd floor of the pool building at the level of +8,400, the following are designed: a control room, a security rest room, an administrator's room, a bathroom for staff, ventilation chambers, a prechamber. Cleaning facilities are provided on all floors. Designed two stairwells type L1 for climbing to the 2nd and 3rd floors with direct access to the outside. Exterior finishing of facades: basement of the building up to +0,900 - porcelain stoneware cladding, brick walls above +0,900 - insulation and porcelain stoneware finishing according to the ventilated facade system or sandwich panels. The covering is flat, combined, with an organized internal drain. The height of the parapet is not less than 0,6 m. There are exits to the roof via external vertical metal stairs. Filling of window openings - metal-plastic window blocks with two-chamber double-glazed windows. Stained-glass windows - aluminum with two-chamber double-glazed windows. Furnishing of rooms is provided in accordance with their functional purpose. The project documentation provides for measures to prevent criminal manifestations, including a security post on the 1st floor for access control and a control room on the 3rd floor. The accessibility of the building for students with disabilities, including swimming pools, changing rooms, showers and sanitary facilities, has been ensured. An elevator is provided for lifting to the 2nd floor and a fireproof zone for the disabled is designed in the methodological room on the 2nd floor.

Structural and space-planning solutions

Building responsibility level - II. The pool building is designed from two blocks - sports and administrative - and is separated by an expansion joint. The building was designed according to the frame structural scheme, the basement was designed according to the mixed structural scheme. The outer walls of the basement are monolithic reinforced concrete, 300 mm thick, concrete class B25, G100, on sulfate-resistant cement, class A500C reinforcement. The external enclosing walls are designed with brick 250mm thick, insulated with a ventilated facade system (developed at the stage of design and development and must have a technical certificate from the State Construction Committee), as well as in the form of stained-glass windows and hinged sandwich panels (thickness 200mm). Partitions are designed from tongue-and-groove hydrophobized slabs 160 mm thick (2 x 80 mm). Columns - monolithic reinforced concrete. The main column spacing is 6 x 6 m in the administrative part and 15,2 x 6 m in the sports block of the building. Section of columns 400 x 400, 600 x 400 and 700 x 400 mm, concrete B25. Ceilings and covering over the administrative part - monolithic reinforced concrete slabs 200 mm thick on monolithic reinforced concrete beams with a section of 400 x 350 mm. Concrete B25. The covering over the sports part is precast prestressed reinforced concrete slabs of the TT3000 type, 700 mm high. The spatial rigidity and stability of the building is ensured by the joint work of the rigidity of the frames, the stiffening cores formed by the walls of the staircases and the rigid disks of the floors. Pool bowls with dimensions of 10x6 and 25x11 m are designed in monolithic reinforced concrete (B25; \U8). The thickness of the walls is 200 and 300 mm, respectively. The bottom of the pool is a beamless slab 200 and 300 mm thick, respectively, based on monolithic reinforced concrete walls 400 mm thick and columns with a section of 400 x 400 mm. Waterproofing is carried out according to the technology of a specialized organization. Stairs are designed from monolithic reinforced concrete, B25 concrete. The calculation of load-bearing structures was carried out on a computer. The foundations are made of 500 mm thick slabs on a natural foundation. Concrete class B25, G100, \U6 on sulfate-resistant cement, reinforcement class A500C. The relative mark of 0,000 corresponds to the absolute mark of 3.35. The base of the foundations is sandy gray sandy loam with gravel, plastic with cp=9°, c=0,13 kg/cm2, /2 2 E \u100d 1,4 kg / cm. Estimated soil resistance of the base - not less than K = XNUMX kg / cm, pressure on the base soil - no more than p = 0,775 kg / cm2. The maximum groundwater level is at a depth of 1,0 m. Groundwater is non-aggressive to concrete of normal permeability. Soils are highly aggressive to betone of normal permeability in terms of sulfate content. In order to protect the concrete of underground structures, the water resistance grade of concrete is \\^6 on sulfate-resistant concrete, the concrete surface is protected by coating with bitumen twice. The design documentation provides for the device for internal waterproofing of the basement by applying the Lakhta waterproofing compound to the surface. It is planned to install sheet piling along the perimeter of the building from Larsen-U sheet pile, 12 m long. The expected draft of the building is no more than -2,7 cm.
