Architectural solutions

The designed building of the swimming pool without stands for spectators is a separate 1-2-3-4-storey building with different cover configurations. A building with a basement, of a broken rectangular shape in plan, with dimensions in the extreme axes of 58,20 x 65,40 m. For a relative mark of 0,000, the level of the finished floor of the 1st floor was taken. The highest vertical height of the building from the planning ground level to the top of the parapet is 19,2 m. Functionally and structurally, the building is divided into two blocks. One block includes sports halls with a group of auxiliary and related premises, amenity premises, administrative premises, catering premises and a technical floor. The second block includes three basins. In the basement floor, pool maintenance rooms (water treatment, dosing of chemical reagents), dressing rooms with showers (separately for administration and staff), rest rooms, generator room, inventory, ventilation chamber, prechamber, water metering unit, engineering communications rooms, utility rooms are designed. On the ground floor, a hall with an administrator's desk and a cash desk, a security room, a cloakroom for visitors, a control room, locker rooms with showers (men's, women's and children's), halls with pool bowls, locker rooms for coaches and judges, a gym, a nurse's office, laboratories, a preparatory classes, judges' room, loading cafe, technical and auxiliary premises. On the second floor, a hall, administration premises, a cafe for 48 seats, a doctor's office with a waiting room, and bathrooms are designed. On the third floor - administrative offices, bathrooms. On the fourth technical floor - ventilation chambers, prechamber, boiler and machine rooms, main switchboard, technical rooms. For evacuation and communication between floors, one stairwell L1 and one stairwell H2 were designed, which have exits to the territory adjacent to the building. Designed metal fire escapes for climbing to the roof and ladders on the height differences of the roof. Independent evacuation exits are designed from the basement floor. The building provides for the installation of a passenger elevator with a carrying capacity of 400 kg, two small cargo lifts with a carrying capacity of 100 kg and one platform lift. External walls - from the planning mark of the ground to the mark of 0,000 - monolithic reinforced concrete with foam insulation and subsequent finishing with porcelain stoneware on an adhesive solution. External walls from the mark of 0,000 to the mark of plus 3,970 m - brick with mineral wool insulation and subsequent finishing with porcelain stoneware according to the "ventilated facade" system. The outer walls above the mark plus 3,970 m are stained-glass windows and a system of hinged self-supporting sandwich panels finished with facade cassettes. Partitions - brick, from aerated concrete blocks, plasterboard (simple and moisture resistant) on a metal frame with mineral wool filling, tongue-and-groove (simple and moisture resistant). Windows and stained-glass windows - aluminum profiles filled with double-glazed windows. Doors - metal-plastic, metal and wooden, glazed and deaf, in fire-resistant and conventional design, custom-made and in accordance with GOST. Roof (covering) - combined insulated: above the multi-storey block - flat low-slope, above the block of pools - gable and flat low-slope. Roofing - from rolled materials, separate operated areas - with a protective coating of paving slabs. The drain is internal. Exterior finish of the building - ceramic granite slabs, aluminum composite facing panels. Finishing of premises and floors - in accordance with the purpose of the premises: floors - granite, porcelain stoneware, concrete, ceramic tiles, TZI linoleum, lint-free carpet. The design of the floors in the halls of the pools is provided according to the "warm floors" system; walls - ceramic, polymer or glass tiles, plaster, water-based paint; ceilings - water-based paint; suspended and false ceilings - slatted, aluminum and "Armstrong" type. Measures are provided to ensure the accessibility of the building for the disabled and people with limited mobility: the dimensions of the entrance vestibule are taken to be at least 1,5 m deep and at least 2,2 m wide; width of corridors - not less than 1,6 m; floor covering - from materials that do not allow slipping, roll materials - lint-free; lifts are designed in the lobby area and on the bypass path of the health pool; width of door and open openings - not less than 0,9 m.

Structural and space-planning solutions

The building of the pool is divided by an expansion joint into 2 blocks. The pool building is designed according to the frame structural scheme. The columns are monolithic reinforced concrete. The pitch of the columns is variable (the maximum pitch is 6,0x9,6 m, in the pool area the pitch is 30,0x3,3÷6,0 m), the section of the columns is 400x400 mm, concrete B25. Ceilings and roofing - from precast concrete slabs with a maximum span of 9,6 m and a thickness of 400 mm, in the area of ​​\uXNUMXb\uXNUMXbrooms with wet and wet conditions - from prefabricated ribbed reinforced concrete slabs. Concrete B25. Covering over the pool - steel trusses with a span of 30 m with a step of 3,3 ÷ 6,0 m, made of closed bent-welded profiles (upper chord - from □ 180x140 x 5, lower chord - from □ 140x5, grating - from □ 100x5) on which purlins made of closed bent-welded profiles and bent channels (step 1,5 and 3 m) and profiled flooring H75 were laid. Horizontal stiffness ties at the level of the upper chord of trusses and vertical stiffness ties from the truss plane - from closed bent-welded profiles. Pipe steel C345 and C255. Vertical braces of the frame stiffness - cross and portal - from closed bent-welded profiles. The outer walls of the basement and basement are made of monolithic reinforced concrete 250 mm thick. Concrete B30. External walls of the building up to elev. +3,970 and in the pool room - according to the "ventilated facade" type, consisting of self-supporting brickwork of ceramic solid brick KORPO 1NF / 150 / 2,0 / 25 250 mm thick on the mortar M75 and the ventilated facade system "AluWALL" (TS 3026-09) . Brickwork - with reinforcement and fastening to reinforced concrete with galvanized steel anchors. The outer walls of the building above el. +3,970 - hinged sandwich panels 150 mm thick finished with facade cassettes. Partitions - from aerated concrete blocks, in rooms with a damp and wet regime - from tongue-and-groove hydrophobized slabs. The bowls of the pools are made of monolithic reinforced concrete. Walls of the big pool - variable thickness from 350 to 200 mm. Walls of small pools - 200 mm thick. Bottom slabs of small pools - 200 mm thick supported on columns through reinforced concrete beams. Beams - section 300x450 mm. The bottom slab of the large pool is made of monolithic reinforced concrete with a thickness of 300 mm. Concrete B25, W8, F100, working reinforcement A-500s. The spatial rigidity and stability of the building is ensured by the joint work of pinched columns, vertical braces and floor hard disks. The load-bearing structures were calculated on a computer using the SCAD Office program and manually using the SNiP formulas. Stairs - prefabricated reinforced concrete steps (series 1.155.1) on metal stringers. The foundations are taken (including pools) pile. Driven piles with a section of 35x35 cm, 19 and 20 m long. Piles are designed according to series 1.111.1-KL-8. Concrete B25, W6, F100. Forces in piles do not exceed 55 tons. Columnar grillage made of monolithic reinforced concrete with a thickness of 400÷600 mm, concrete class B25, W8, F100. The connection between piles and grillage is rigid. The calculation of the foundations is made manually according to the formulas of SNiP. The relative mark of 0,000 corresponds to the absolute mark of 6.02. In accordance with the report on engineering and geological surveys, the base of the foundation is dusty gray sandy loam with gravel, plastic pebbles with IL=0,26, E=120 kg/cm2. The permissible design load on the pile (64 tf) was adopted based on the results of static sounding. Before mass pile driving, the bearing capacity of the piles will be checked by static tests. After driving the piles, control tests of the piles will be carried out. The maximum level of groundwater is at a depth of 0,8 m. Groundwater is non-aggressive to concrete of normal permeability.
