The Qatar World Cup is the latest global event attracting worldwide attention. The 2022 Qatar World Cup will attract global attention once it is opened on November 20.
The main stadium of the World Cup – Russell Stadium, as an activity venue, has frequently been on the hot search. Most notably, it is the first World Cup venue constructed by China as the general design and construction contractor, which has created many Chinese and world records. It is known as the World Cup main stadium with the largest scale, the most complex system, the highest design standard, the most advanced technology and the highest degree of internationalization in the world.
In addition, many Chinese enterprises have participated in the grand competition and remarkable infrastructure construction:
CRCC undertook the sports venue of the World Cup – Russell Stadium;
Seiko steel structure jointly participated in the construction of the Russell Stadium;
PowerChina undertook the construction of the first photovoltaic power station in Qatar, and made many efforts to ensure the power demand of the World Cup;
……
Among them, the Qatar photovoltaic power station contracted by China Power Construction Corporation installed 2 million solar panels, with a total investment of 417 million dollars.
Screwman is no stranger. PV is an important part of the new energy industry and is being used in various key projects. PV panels need to use a large number of fasteners. Stainless steel fasteners are widely used in the photovoltaic industry as the “strong” of anti-corrosion and impact resistance. At the same time, for the sake of later maintenance and repair, various fasteners with anti loosening and locking functions are also preferred.
In the first two years, the country introduced new infrastructure projects. The construction of new infrastructure mainly focuses on the development of science and technology, including the 5G infrastructure, intercity high-speed railway, new energy vehicle charging pile and other seven fields. The development of new infrastructure indicates that the fastener industry has new and additional development opportunities on the basis of the original traditional infrastructure. With the new development, fasteners have more possibilities.
This time, at the Qatar World Cup, Chinese enterprises clearly demonstrated their capabilities in new infrastructure projects. In the process of construction projects, from design to construction, Chinese enterprises have provided a series of solutions, completed the integration of different construction projects, steel structure projects, large machinery, ultra-high strength fasteners and other domestic resources, and worked together to make every place of the Cartal World Cup where Made in China appeared.
Whether it is a super large infrastructure project like the Russell Stadium, or a small and medium-sized construction project, fasteners are everywhere and silently guard the infrastructure safety. Fasteners are frequently used in construction machinery, equipment and facilities, and structural connection. Different applications have different strict quality standards.
The surface connection of Russell Stadium is very complex, and tens of thousands of connectors are used in it. It is understood that 4672 connectors are required for the entire front wall. These fastening connections shall not have any deviation, otherwise the shape will be changed. It took a lot of effort to install fasteners and aluminum plates. Finally, technicians overcame the problem by using technology skills such as dynamic positioning and simulation technology.
In the selection of fasteners, such large-scale infrastructure must be strict. For example, the general performance of the locknut can not meet the requirements of the stadium, so the high-strength locknut dedicated to large-scale infrastructure equipment and facilities should be used, and the product manufacturing, testing and heat treatment should pass the standard.
High strength bolts are also often used in building structures, but high strength bolts commonly used in building structures cannot be reused, so the requirements for such bolts are higher. High strength bolts are generally Grade 8.8 and Grade 10.9, of which Grade 10.9 is the most widely used.
In addition to infrastructure projects, Chinese automobile enterprises are also involved. Among them, China’s Yutong Bus and Jinlong Automobile have become the only suppliers of special buses for the Qatar World Cup, and they are also environmentally friendly pure electric buses. This is the first time that China’s new energy buses have been introduced in large quantities in international large-scale sports events.
The machining accuracy of high-strength fasteners for automotive engines is very high, and the accuracy and stability of processing equipment are very important. Fasteners used for vehicles on site in Qatar are more strict, and have a sound management system for equipment selection, testing, etc.
The reporter interviewed the Chinese enterprises’ engineers stationed in Qatar about the World Cup operating vehicles. He said that because the local temperature in Qatar is relatively hot, it is a challenge to the performance of power batteries and vehicles, which requires staff to pay attention to the performance of new energy vehicles and conduct real-time monitoring.
As we all know, one of the quality properties of automobiles is determined by the manufacturing technology of automobile fasteners. In particular, new energy vehicles need high-performance, high light and high-precision fasteners, high-quality high-performance bolts, which play an important role in the lightweight of automotive vehicles.
If fastener enterprises want to match high-performance new energy vehicles, they need to develop and improve new materials, improve manufacturing technology, make vehicles and fasteners closely fit, and conduct synchronous research and development. Finally, the functions of the whole vehicle and fasteners are highly matched and coordinated, so as to move forward in a more important field.
Whether it is a capital construction project or a transportation trip, there are many places that need fasteners. In recent years, China’s production and manufacturing capacity in high-strength fasteners has been improving and applied in more and more important projects.
The ability of Made in China to compete in the Qatar World Cup is a proof of the continuous progress of China’s manufacturing industry and R&D capabilities. Scientific and technological innovation and equipment manufacturing are strong backing. In the process of innovation, fasteners in China are also emerging in every large-scale infrastructure, high-speed rail and aviation, and are moving towards becoming high-end supporting industry chains in many industries.
