The Best Competition Time of the Olympic Park Hockey Field

The best time for the Olympic Park hockey field: Beijing is neither too hot nor too cold in spring and autumn, and the climate is mild. This is an ideal tourist season, especially in autumn, with clear sky and pleasant climate. It is praised as "Golden Beijing" by Chinese and foreign tourists. The best tourist months in a year are April, May, September and October.

Beijing is located on the northern edge of North China Plain, surrounded by mountains and the sea. It is a typical warm temperate semi-humid continental monsoon climate with four distinct seasons. Spring flowers, autumn moon, summer rain and winter snow have their own characteristics. The annual average temperature is 1 1.8℃, the coldest is 1.6℃, the hottest is July, and the monthly average temperature is 26. 1℃. Beijing has shorter spring and autumn seasons and longer winter, with an average annual precipitation of 644 mm and a frost-free period of 180 days. Although the winter in Beijing is very long, the indoor heating equipment is very good and warm as spring. Because of the great temperature difference between indoor and outdoor, you still need to take a sweater and a cotton coat when you travel to Beijing in winter.

Newspapers, radio stations and TV stations in Beijing all have weather forecast columns and explanations, so please pay attention. You can also call 859, which provides the weather forecast in English and Chinese for the same day and the next day.

However, most of Beijing's tourism projects are cultural relics, scenic buildings and folk customs. These projects are not affected by the climate, so you can visit Beijing all year round. In winter, travel agencies and restaurants in Beijing offer off-season prices, which can save a lot of money.

There are three competition venues in the Olympic Forest Park: Olympic tennis court, Olympic hockey field and Olympic archery field. Among them, hockey and archery field belong to temporary venues. After the 2008 Beijing Olympic Games, artificial lawns and other parts will be used in other ways.

Geographical location and land occupation

The hockey field is located in the south of the Olympic Forest Park, with a total construction area of 15546 square meters. It is mainly composed of the final venue, preliminary venue, 14 annex, stands, various auxiliary parking lots and road facilities. The final venue is located on the west side of the land center, with 12000 seats; The preliminary venue is located on the east side of the land center and has 5000 seats. Of the 14 ancillary buildings built around, 6 are functional rooms in the back yard during the Games, and 8 are rooms for spectators in the front yard during the Games.

1. Hockey courts require high water permeability and water retention.

There are also hockey fields and archery fields in the Olympic Park, and their positions echo the tennis center in the park. In the construction of hockey field, it is a test for the project to develop turf that can effectively penetrate water and maintain proper moisture in Beijing's dry soil environment. At present, the turf of hockey field has been determined, and the design of the whole grass layer should be determined next month.

The person in charge of hockey field construction said: As the Olympic hockey venue, there are clear requirements in many aspects, such as water seepage, water retention, ball rebound, ground sole friction, ball rolling performance, rolling deviation and so on. Among them, the double requirements of both water seepage and water conservation put forward a new test for construction. According to the requirements, after sprinkling water for 35 minutes, the average water on the surface of the stadium is 3 mm, and the water in any place should not be less than 2 mm. Therefore, the construction personnel adopted the five-layer paving method of lime-fly ash soil, coarse asphalt, medium asphalt, lawn damping layer and artificial lawn, which passed the examination of the International Music Federation and reached the highest certification standard. It is reported that the stadium will become the highest level hockey venue in China after its completion.

2. Green Olympics: It is green before, during and after the games.

The Olympic Park Hockey Field with a building scale of 15546 square meters is mainly composed of Hockey Field A, Hockey Field B, 14 ancillary buildings, stands, various auxiliary parking lots, roads and facilities. Hockey field A is located on the west side of the land center. As the final venue, the audience capacity is 12000. Hockey field B is located in the east of the land center, which is a preliminary venue that can accommodate 5000 seats. During the Olympic Games, it aims to hold the Olympic Games men's hockey (12 team) and women's hockey (10 team) competitions; The purpose of the Paralympic Games is to hold five-a-side and seven-a-side football matches of the Paralympic Games. As the host of the 29th Olympic Games in 2008, there will be two gold medals in men's and women's hockey.

3. Interpret the concept of green Olympics in the park before the Games.

In the process of construction, the construction unit pays great attention to the cleanliness of the site. The blue enclosure on the construction site is uniform and the publicity column is patchy. The road surface is clean and tidy, and all kinds of materials, finished products, semi-finished products and waste products are listed in piles. Material identification boards, floor passage signs and safety warning signs can be seen everywhere in the construction site. In the living area of migrant workers, there are clothes drying areas, reading rooms and shower rooms.

Then according to the first article, the division of labor and the implementation of responsibilities are clearly defined. Then, an evaluation is performed. Ways to keep the garden site clean and tidy: throw cigarette butts and fine; A fine for not wearing a helmet; The construction site is specially cleaned every day, and it is legal to clean it three times in the morning, noon and evening, and not once; There should be no dust on the on-site fire fighting equipment; You can't leave a pimple the size of a broad bean on the construction site.

After a period of time, the completion of work, the exhaustion of materials and the clearing of the site gradually become the last process of daily construction, and the construction workers will consciously put the garbage and waste in the designated place. Gradually, everyone got used to nature, and the construction site became a green one.

4. Paving and greening will be carried out during the Games, and Olympic Forest Park will be built after the Games.

The hockey field and archery field in the Olympic Park are temporary venues, which will be restored to the green space of the Olympic Forest Park after the games.

In addition, in order to embody the concept of green Olympics, the sewage from the functional and auxiliary rooms of the archery range enters the self-built sewage treatment station to generate reclaimed water for recycling such as greening and watering, so as to realize zero sewage discharge; All air conditioning systems adopt fluorine-free environmental protection refrigerants, which do not destroy the ozone layer and realize the environmental protection commitment to BOCOG. Choosing energy-saving and environmental-friendly solar energy as the bath water heater for athletes and officials not only saves electricity, but also can be recycled after use; At the same time, permeable bricks are laid on the sidewalks and squares of the stadium, so that rainwater can penetrate underground and be directly recycled.

5. High-tech Olympics: Attach importance to the application of science and technology and persist in independent innovation.

In the design and construction of Olympic hockey field and archery field, relevant parties actively implement the concept of high-tech Olympics. In addition to a series of designs such as steel structure and solar energy, the second company of Beijing Housing Corporation, the construction party, set up a scientific and technological research team, and successfully adopted new materials and technologies such as integrated thermal insulation decorative finished board, external wall thermal insulation technology, stand waterproof technology and artificial lawn technology of outdoor training ground, which not only improved the scientific and technological content of the project, but also accelerated the progress of the project and ensured the construction quality of the reconstruction and expansion project of the Olympic ice hockey training ground.

The project department actively cooperated with the design unit to promote the application of new materials and technologies, sealed the joints of steel plates with weather-resistant glue, and used the one-component polyurethane of Bayer Company in Germany as the indoor waterproof material, which solved the technical difficulties in waterproofing the joints between the stand slope and the functional building. At the same time, in order to reduce the vibration and noise of the stands, the project department independently innovated and changed the original design of the lap joint between the grating plate and the stand to a short lap joint. The test shows that this small change not only reduces the solder joints and saves the cost, but also has a good noise reduction effect. The steel structure construction of hockey field won the Beijing Great Wall Cup Award.

The hockey field project is a temporary venue, but the general living group requires that the project must be done in accordance with the standard requirements of the official venue to ensure the use of functions and ensure completion. There is a contradiction between the maintenance of color steel plate in auxiliary building and the installation of water and electricity. It is very difficult to drill holes in tile iron, install power switch and clean basin and mirror safely, and it is irregular, which affects the appearance. Technicians put their heads together and skillfully installed stainless steel pads at the hole of the joint, which solved the aesthetic problem well.

Environmental protection solar shower equipment, originally designed for centralized supply throughout the site, has long pipes and poor heat preservation effect. Technicians adopted the suggestion of Qin Yunshan, the chairman of Jules Company, and redesigned and laid out the solar energy, which not only solved the heat preservation problem, but also saved water pipes. Fire-proof boards are selected instead of fire-proof coatings to meet the fire-fighting requirements, and the fire-proof boards can be recycled, which fully embodies the concept of running the Olympics diligently.

In addition, the artificial lawn of Australian international brand is selected for hockey field, which has three characteristics of smoothness, water retention and water permeability, and better embodies the concept of high-tech Olympics.

6. From design to construction, people's Olympics are being staged in ice hockey venues.

At the beginning of the design, each stand of the hockey field has a two-way ramp for the disabled, a unique shower and a 1 10 bathroom. During the construction period, the construction party changed the width of the hockey field from1.2m to1.8m, etc. This is also a good interpretation of the construction concept of the People's Olympics.

In addition, the operation mode of ice hockey project is multi-discipline, multi-job, multi-team and interspersed operation, which increases the difficulty for the overall coordination of field commanders and puts forward a severe test for logistics support. As the saying goes, the soldiers and horses have not moved, and the food and grass go first. The Olympic Project Department of the Second Company of the Owner's Housing Corporation strictly abides by various rules and regulations, and puts forward high standards and strict requirements for the accommodation of migrant workers, which improves the living conditions of migrant workers to the greatest extent and provides a solid guarantee for the battle ahead. First, set up standard living quarters, health rooms, activity rooms and solar bathrooms, and assign special personnel to clean them every day. Toilets are sprayed with disinfectant every day; The second is to care for the health of migrant workers and hold large-scale medical clinic activities; The third is to establish night schools for migrant workers and insist on studying and training twice a month; The fourth is to formulate and implement the Measures for the Administration of Living Areas for Foreigners, the Measures for the Administration of Domestic Waste and the Detailed Rules for Food Hygiene and Prevention of Food Poisoning; Fifth, all migrant workers should be registered in real-name registration system, and wear work cards, temporary residence permits and workers' grade certificates, so as to be standardized and institutionalized.
