- Abstract:
- The National Sliding Centre in Yanqing Competition Area of 2022 Beijing Winter Olympics is the first standard venue constructed in China. It is also one of the venues with the highest design and construction difficulty and the most complex construction technology in the Winter Olympics. It has the characteristics such as large floor space, multiple building subitems, scattered distribution and large terrain elevation difference. Therefore, its fire water supply system design is quite challenging. Combined with project characteristics and municipal conditions, four kinds of fire water supply system schemes were formed with the development of the project and the evolution of external conditions. The advantages and disadvantages of different schemes were discussed from three aspects including engineering quantity, feasibility and reliability. The scheme Ⅳ was eventually adopted. That is, the departure area 1 and departure area 2 adopt temporary high-pressure fire protection systems, while other single buildings in the competition area adopt high-pressure fire protection system. The two systems shared the same fire water tank, forming a combination of high-pressure and temporary high-pressure fire water supply system scheme, which can provide a reference for the design of fire water supply system of large venues in mountainous areas and mountain building groups.
