Intelligent manufacturing "adds wings" to China's high-speed rail
2022-07-28
Recently, the Puyang Jinan section of the Jinan Zhengzhou high speed railway is under intense construction. In order to speed up the construction progress, China Railway Third Bureau, the construction party, is the first in China to apply the intelligent construction technology of fabricated bent cap to the field of high-speed railway construction, which makes the high-speed railway construction "like a tiger", marking that the intelligent construction of high-speed railway in China has stepped to a new level. On July 25, the reporter saw at the construction site that the traditional scene of a large number of workers erecting formwork, binding reinforcement and pouring pier concrete no longer exists. The construction personnel prefabricated the main engineering components of High-speed Railway Piers such as bent cap and pier column in the intelligent workshop in advance, and then transported them to the construction area to complete the assembly as quickly as "building blocks". "The intelligent construction technology of fabricated bent cap has changed the traditional construction mode of high-speed rail." Sun Maosong, executive vice president of the Institute of artificial intelligence at Tsinghua University, told reporters, "For example, this is like building a house. The traditional building of a house is built brick by brick on the site, which is time-consuming, laborious and polluting the environment. Now it is time to make 'prefabricated blocks' in the factory and only need to assemble them on site. This mode can not only improve efficiency and reduce pollution, but also ensure the quality of products due to standardized design and production." In recent years, the state has vigorously promoted the digitalization and intelligent transformation and upgrading of traditional manufacturing. China Railway Third Engineering Bureau accurately grasped the new development stage, implemented the new development concept, accelerated the transformation and upgrading of engineering construction from traditional construction methods to intelligent construction, and increased the new energy and vitality of engineering construction. "Aiming at the needs of pain points, since the construction of Zheng Ji project started in May 2021, we have integrated advanced technologies such as digital simulation, intelligent vision, intelligent robot and Internet of things into various production processes in the production of bent cap of prefabricated pier, built the first intelligent production line of large and medium-sized prefabricated concrete prefabrication in China, and realized the intelligent factory prefabrication of prefabricated pier components of Zhengzhou Ji high-speed railway in Henan Province." Wang Jin, director of the Technology Development Department of China Railway Third Bureau, told reporters. It is understood that intelligent prefabrication, through advanced digital intelligence technology, comprehensively manages the people, machines, materials, methods and environment in the production of bent caps in the intelligent factory, improves the production efficiency of bent caps, ensures the production quality of bent caps, and significantly improves the intelligent process of bent cap prefabrication production equipment. "The successful application of intelligent prefabrication in Zhengzhou Jinan high-speed railway has effectively shortened the production and construction cycle, improved the quality control level of products and projects, reduced the impact on the environment, and provided an effective guarantee for the safe, high-quality, intelligent and green construction of high-speed railway." Wang Jin said that compared with the traditional construction method, the assembly construction can improve the efficiency by more than 30% and reduce the on-site operators by more than 40%. At the evaluation meeting of scientific and technological achievements of the project "research and application of intelligent construction technology for prefabricated bent caps" held in Puyang, Henan Province on July 17, industry experts such as sun Maosong, academician of the Chinese Academy of Engineering Sun Yu, and deputy chief engineer Wu Wei of CETC 54 Institute agreed that the research and development technology of this achievement is difficult and comprehensive. It has been authorized by a number of domestic technical patents, has complete independent intellectual property rights, and the overall technical level has reached the international leading level. The economy Remarkable social benefits and broad application prospects. According to the introduction, the successful application of the intelligent construction technology of prefabricated bent cap on Zhengzhou Jinan high-speed railway will produce linkage and demonstration effects, promote the improvement of the intelligent construction level of high-speed railway, increase the diversity of railway bridge construction methods, and better meet the high standard requirements of rapid construction, environmental protection, low noise and so on in urban areas, environmental protection zones and other environments. "In the future, China Railway Third Bureau will promote the intelligent construction of engineering into a series of technical industries, form the intelligent factory production of large, medium and small series of concrete components such as simply supported box girders, piers, track slabs (sleepers), auxiliary components, and make the concrete component prefabrication intelligent factory bigger and stronger, and make a brand." Wang Jin said. (Xinhua News Agency)
