Flexible protection technology was born in Europe in the 1940s and was introduced into the Chinese market in the 1990s. After nearly ten years of engineering application, flexible protective net technology has achieved certain development in China. The Wenchuan earthquake on May 12 in 2008 made the flexible protective net technology undergo a "real gun and live ammunition" test. The result was that the protective net system collapsed, and the falling rocks could not be stopped or covered! This has caused significant losses to the lives and property of the country and the people.

What's the problem? What is the reason? what to do? This question is sharply placed in front of the company's management team. After analysis and research, it is unanimously believed that China's flexible protection network technology is backward (60 years behind foreign countries) and has weak protection capabilities (protection level 250KJ, 8000KJ abroad, an order of magnitude difference). The fundamental reason is that China lacks flexible protection network system detection equipment and product performance No verification test. Over the past decade, we have done a lot of fruitful work closely around the "improving flexible protection technology", changing the current situation where protection technology lags behind foreign countries for 60 years, and achieving a leap in China's protective network technology for 60 years. Sichuan Aoist Slope Protection Engineering Co., Ltd. has become an enterprise integrating flexible protection technology research, product design and development, production and manufacturing, survey and consulting, engineering design and construction installation. It is the three standards of the Ministry of Transport's "Flexible Protection Network System" One of the main drafting units is one of the three companies that fully master flexible protection technology around the world. The company's business covers multiple fields of railway, highway, hydropower industries and geological disaster prevention and control, and has become a leading enterprise in the domestic flexible protection industry and a leading enterprise in the development of protection network technology.

Scientific research

The company took the path of school-enterprise cooperation, leveraging the talent advantages of Southwest Jiaotong University, Chengdu Science and Technology and scientific research institutions, and established a scientific research and development team led by professors and senior engineers. It has the industry's first-class scientific research level and product development capabilities, and dozens of papers are in many places. This article published in core Chinese journals, accounting for 70% of industry papers. Over the past decade, 140 million yuan of scientific research funds have been invested.

Technology development

The company has established a world-leading foot-size impact testing platform, and has multiple sets of flexible protection network static testing and testing equipment. The flexible protection product testing and testing technology is in the leading position in the industry. The series of products developed by the company have obtained more than 70 utility model patents and invention patents; in 2020, the company's flexible protection technology has obtained the progress of battlefield protection technology in the People's Liberation Army of China. Second prize, the company's flexible protection technology won the first prize of Science and Technology Progress of the China Transportation Association in 2021.

Quality assurance

The company has established a technical standard system with product quality standards as the main body. In July 2009, it passed the IS0 9000 quality management system certification for the first time, and passed the GB/T 19001 and GB/T 50430 quality management system certification in 2012, 2015, 2018, 2020 and 2021 respectively. The Weining collapse test in Guizhou, the Fuling energy dissipation test in Chongqing, and the Guanghan Pine Forest Sub-guiding test were carried out, and the performance of the system products and components was comprehensively tested. Actively participate in the editing and promotion of national industry standards, and adhere to the current national standards "Methods and Evaluation of Rockfall Impact Testing of Flexible Passive Protection Products on Railway Slopes") JT/T 1328-2020) and "Slope Flexible Protection System" (JT/T 1328-2020) and the EU ETAG027 standard organize production and inspection, the protection system performance has obtained CMA quality certification, and it meets the A-level standard. The CNAS and national CMA certification reports are obtained for component performance and anti-corrosion testing.

Engineering Design

The company focuses on engineering design, and customer needs are the direction of product development and service. The company introduces and integrates advanced survey and rockfall analysis technologies from the United States, the United Kingdom and Japan, and introduces first-class hardware and software equipment, which can accurately measure and analyze large and complex mountains and slopes, and provide scientific protection engineering design solutions. Up to now, the company has undertaken and completed technical services and engineering installations of more than 1,200 domestic projects and nearly 100 international projects, with a project quality rate of 98%. The "Integrated Solution for Guided Protection Systems" provided to customers by Beijing Mentougou Sanwen Road and Lingshan Road, Guangzhou Qinglian Expressway, and the "Integrated Solution for Passive Protection Systems" of Baocheng Line K425 Working Point have been successfully applied and praised by customers; The Xicheng Railway Red-crowned Crane Flexible Protection Network Project, which was constructed, won the 18th China Civil Engineering Zhan Tianyou Award.
