Tiejian Heavy Industry "China Roadheader" Wins the First Hunan Provincial Product Innovation Award

Hunan Innovation Award Certificate

It is reported that the "Hunan Provincial Innovation Award" is a new award. It is jointly commended by the Hunan provincial party committee and the provincial government. The award certificate is issued by the provincial Party committee secretary and the provincial governor. It is the highest level and most influential annual science and technology award in Hunan Province. The biggest highlight of this science and technology awards and innovation conference. The 10 Product Innovation Awards that were awarded this time are the result of massive innovations in the province's industrial and agricultural fields in the past three years. After undergoing various layers of selection, they represent the highest level of manufacturing in Hunan and even in China. They are truly "created in Hunan. "" China creates "new business cards."

It is understood that open rock tunnel boring machine (TBM) is China's first large-diameter full-face rock tunnel boring machine independently developed by Tiejian Heavy Industry relying on the 12th Five-Year National High-Tech Research and Development Program (863 Program) and is known as the construction machinery. The "aircraft carrier" and the "drilling machine king" of the tunnel boring machine possessed 7 advanced technological innovations and applied for more than 30 patents, including more than 20 invention patents. It is the first open rock tunnel excavation with complete independent intellectual property rights in China. Machine national industrial brand. The product has an excavation diameter of 7.93m, a total length of 205m, a total weight of 1500t, and an installed power of more than 5000kW. It integrates tunnel excavation, support, slag discharge, ventilation, and drainage, and can complete tunnel construction in a safe, environmentally-friendly and efficient manner. Relying on this project innovation, Tiejian Heavy Industry broke through the large-diameter TBM multi-system coordination technology, high-power, variable-load, high-precision electro-hydraulic control system design and integration technology, electro-hydraulic hybrid drive system, cutter disk variable diameter technology, and key component status. Monitoring and diagnostic technologies, as well as vibration analysis and vibration reduction technologies, and other core technologies have overcome technological bottlenecks that have constrained the development of the industry and have achieved major breakthroughs in the development of major countries. This product has taken the lead in completing tunnel penetration since the construction of Jilin Songlin Project, creating a breakthrough of 86.5m in the daily progress, and the most successful tunnel construction in the 1200m tunnel, successfully challenging the "long distance, large burial depth, high stress, and high water pressure. "High temperature, high temperature, large water inrush, easy rock burst" world-class geological problems, the transformation of high-strength, high-risk, high-pollution tunneling engineering operations into a safe, efficient and green construction mode to meet the tunnel construction is fast, high-quality, efficient and safe , environmental protection, and high integration of construction requirements.

On May 28, 2017, China Railway Construction Heavy Industry Co., Ltd. will soon celebrate its 10th anniversary. The award's acquisition reflects the government, society, and industry’s high recognition of the independent innovation of Tiejian Heavy Industry, and presented a thicker anniversary to the Group’s 10th anniversary. The gift, as a young enterprise that established its tenth anniversary, quickly developed into a leading company in the national roadheader equipment manufacturing industry in a short period of time, and created an industry legend. Tiejian Heavy Industry has always been revitalizing the national industry as its mission, persisting in building its rapid independent innovation capability into the company’s core competitiveness, and continuously making innovative breakthroughs in the field of roadheaders. It has successfully developed the world’s first dual-mode inclined well TBM, the world’s first Taiwan permanent magnet synchronous drive shield machine, domestic first large-diameter hard rock tunnel boring machine (TBM), domestic first single shield TBM, domestic first double shield TBM, domestic first large-diameter earth pressure balance shield machine , China's first "big burial, variable diameter" open hard rock boring machine (TBM), 11-meter domestic first high-speed railway large-diameter slurry shield machine, 13-meter domestic first large-diameter mud balance shield Construction machine, 3m domestic minimum TBM and other iconic tunneling equipment. Since TJC's TBM products were put into use in national key construction projects, it has been used in frequent successes and has made repeated efforts to create and refresh TBM construction records at home and abroad. With excellent performance, reliable quality, excellent quality, and good market performance, TBM products have repeatedly created and refreshed TBM construction records. Recognized by users and recognized by the market, the domestic market share has reached more than 80%, leading China's rock boring machine technology to catch up with similar foreign products and reaching the international advanced level. In June 2016, TJM TBM was the most successful construction machinery industry in China. The self-innovation high-end equipment represented by the company was successfully selected into the National Twelfth Five-Year Scientific and Technological Innovation Exhibition. It was reviewed by party leaders Xi Jinping and Premier Li Keqiang. The CCTV “Focus Interview” also focused on Tie Jian’s TBM. The outstanding performance in the national construction and construction has been acclaimed by all sectors of the society. Tiejian Heavy Industry TBM has become China's TBM brand and the most beautiful national business card for high-end equipment innovation, leading the Chinese shield from "Made in China" to "Created in China." "Innovation and development.
