Object - Sports stadium for speed skating - a complex and multifunctional building. The main purpose is to conduct an educational and design process in speed skating, meat hockey, ice hockey, curling, short track, figure skating and holding competitions at the international level. According to the design assignment, the object is characterized as a universal ice arena with a medical and rehabilitation center and a swimming pool. The parameters of the hall of the ice arena are determined by the skating track for a distance of 400 meters and seats for spectators for 2500 seats. with an increase of up to 3000 due to collapsible structures. There are 35 seats for MGN viewers. The space-planning and compositional solutions are substantiated by the parameters necessary for holding speed skating competitions, the conditions of visibility from the spectator stands, and the conditions for ensuring the broadcasting of competitions of a high international level. In the space-planning solution of the complex, the main volume of the ice arena hall is allocated. Large-span coating, made in wood-glued structures, arched trusses. The main volume of the arena hall has an iodo-cylindrical covering, ending with semi-domes on the turns of the stadium. A sports building with a swimming pool, a medical and rehabilitation center is allocated in a separate block. All the main functional areas of the complex are read in the architectural and compositional solution. Entrance spectator zone: vestibule groups, control, cash desks, cafe are turned to the avenue. The medical rehabilitation building with halls and a swimming pool is close to the border of the site from the side of the park. At the ends of the sports building, from the ground level, two radially curved ramps lead to mark 5.5 - the “inner street”. All VIP guests, competition officials, judges, arbitrators have access to their entrance areas; at the level of the second floor of the ice arena there are groups of rooms and boxes facing the hall. In the VIP area for guests and officials, there is an elevator and stairs that lead directly to the arena field. The layout and calculation of the premises were made according to the technological task of the Institute of Sports Facilities. The sports building with a medical and rehabilitation center, a swimming pool, halls, locker rooms and auxiliary facilities for athletes has four dispersed entrance groups. The building is two-story and the planning solution provides not only conditions for training high-class athletes, but also the possibility of using it to visit citizens in their free time from training. For visitors of the MGN group, visits to the pool, halls, saunas and medical rooms are provided.

Structural characteristics of the designed building.

The projected building is a 3-storey oval-shaped structure with a span of 98m and 2 1- and 2-storey outbuildings with basements for engineering facilities and a parking lot. The constructive scheme of the building is a system of monolithic reinforced concrete walls, columns, beams, etc. monolithic reinforced concrete floor slabs resting on them, which ensures the spatial stability and immutability of the building. The outbuildings are cut off from the main structure of the skating rink by temperature-settlement seams. Separate above-ground structures on separate foundations. The ice field is also cut off from the main load-bearing structures of the ice rink by a temperature-settlement seam. The extensions and the main structure of the ice rink are separated by temperature compartments with expansion joints / separate above-ground structures on a common foundation. Building II degree of responsibility with y=1. At all stages of construction and at its completion, it is necessary to conduct geotechnical monitoring of the complex under construction, which includes:

- control over precipitation of the structures of the complex under construction,

- control of compliance with the technological regulations of work,

- control of the technical condition of the erected structures.

The criterion for the completion of monitoring work is the stabilization of the deformations of the designed building.

Foundations

The level of the ice field was taken as ± 0.000, which corresponds to the absolute mark +12.800. 800 mm for outbuildings and an ice field made of concrete class B600 W25 F6 on a pile foundation. Concrete preparation of thicknesses is provided under the foundation slab. 100 of concrete class B100. When performing work on the installation of a slab-piled foundation, be guided by the rules for the production and acceptance of work SNiP 7,5-3.02.01. TSN 83-50-302 and TSN 96-50-302. The project provides for bored piles made using the FUNDEX technology, o2004/450mm b~520^18m from the ground with abs. elev. tips -20 for the main load-bearing structures of the ice rink and outbuildings, and 10.000O/035Omm b = 42-I12m from the ground with abs. elev. points -4 for the ice field made of concrete class VZO W4.000 F6. Piles are carried out in accordance with the technological regulations developed by a specialized organization.
