Beijing Olympic Water Park is the first Olympic venue to be tested for completion after the completion of the competition. Jean-Pruono, the president of the International Federation of Slaves Incidental Recirculation Committee, commented that it is "an international first-class standard." And its builders, Beijing Construction Engineering Group, a construction company is most proud of: "Olympic Water Park in the construction of a large number of the use of advanced science and technology, presented to everyone is an energy-saving, green Olympic venues." Olympic Water Park is the 2008 Beijing Olympic Games rowing, canoeing, marathon swimming and Paralympic rowing competition venues, located in Shunyi District, northeast of Chaoyangbai Bei Xiaoying Beixiao Zhen. Venue construction planning area of ​​about 162.59 hectares. The total construction area of ​​about 32,000 square meters, of which a permanent construction area of ​​about 18,000 square meters, the temporary construction area of ​​about 14,000 square meters. "Water source air conditioning" more than half of winter energy saving Shunyi Olympic Water Park central air conditioning uses groundwater resources heat pump air conditioning. Unlike ordinary central air conditioning power consumption, fuel consumption or gas, it is the use of energy contained in the soil heating or cooling. According to Cheng Yan, project manager of a construction company water park in Beijing Water Conservancy and Hydropower Park, general contractor for water park construction, compared with ordinary air-conditioners, water-source heat pump air-conditioners can save 20% -30% of summer air-conditioning energy while winter-heat energy can save more than half . Water source heat pump air conditioning system is groundwater as a heat source, by the water source heat pump units, shallow geothermal energy acquisition system and building heating and cooling system composed of air conditioning system. It does not have any chemical reaction and pollution discharge, without the cooling tower, boiler room, low operating costs. In addition to complete the cooling, heating tasks, it can also provide domestic hot water. Water Park project in the hydrostatic boathouse, main stand two water source heat pump room, for hydrostatic dinghy, dinghy library and the main stand and other buildings for cooling, heating and domestic hot water. "No one was transported out of garbage" "When digging this water park, we did not have one of our garbage shipped out." Zhang Gang, head of the water park technology at a Beijing-based construction company, said. During the construction and construction, the water in the Olympic Water Park has been excavated for 2 million cubic meters of earthwork, all of which is sandy soil with poor soil quality and can not be directly used for construction. If discarded, soil replacement will inevitably cause huge environmental pollution and farmland damage, and the cost is high. They backfill these sand "self-produced". In addition, a mountain of landscapes was piled up in the park, thus completely eliminating the earthwork generated by itself and eventually losing one cubic meter of inferior soil. This has never been done before in the construction of venues. Water purification once a month "Water Park in the design of the most difficult is how to maintain the track water quality." Cheng Yan said. The water inside the stadium is stagnant water, do not have the conditions of natural circulation cleaning, if only rely on water and water to maintain water quality, the price is immeasurable. The Olympic Water Park opened the hydrodynamic area and the hydrodynamic area, making the hydrodynamic area the "driving force" of the entire circuit water cycle. The Olympic Water Park under water to establish an underground track water cycle processing station, 24 hours a day non-stop operation, the water to be treated inflow from the hydrostatic circuit, training road outflow. The processor purifies 72,000 tons of water a day, purifying the entire track once a month. What's more, it boasts the world's most advanced ozone filtration and cleaning system that automatically keeps water quality at optimum levels. Sewage to achieve zero discharge As the water cycle system in dealing with the track water, the system itself to the recoil purification, it will also produce part of the sewage. In order to purify this part of the sewage, a tail water treatment station is also set up on the side of the track water circulation treatment system to purify the recoil sewage generated by the circulation system. The treated water will be used for watering and settling Sludge will be used as fertilizer to achieve zero discharge of sewage. In addition, in order to make full use of water resources, water for drinking water, domestic water and reclaimed water in water parks shall be subject to the principle of "high quality, high quality, low quality and low use", in addition to the track water cycle treatment system. Direct drinking water is provided after treatment. Green water is supplied from groundwater and partially reclaimed water. In afforestation, drought-tolerant plants are selected and central computerized control systems are used for irrigation. Programming is performed according to different plant and soil water requirements and automatic irrigation is achieved, saving 30% water.
Brass fasteners are used for their physical and aesthetic properties. Brass is utilized due to its high thermal conductivity and corrosion resistant properties, it is suitable for use in hot and cold environments, and resistant to water corrosion, making it a staple of industries such as heating and plumbing. Brass fasteners are largely non-magnetic (like any fastener, slight magnetic properties can develop during the manufacturing process) and resistant to tarnishing.
Brass fasteners are suited for some marine environments, including brackish water and slow current sea water; brass in this environment develops a protective green coating. Brass fasteners are also commonly used with wood applications, as the golden coloring blends well with the tan wood. Brass is a softer metal and must be used with care, always drilling pilot holes and using driver bits that fit the head of the screw precisely to prevent stripping. Brass Bolts also require a pilot hole be driven before installtion.
