Du Jiahao, the secretary of Hunan Provincial Party Committee, and Xu Dazhe, the Governor of Hunan Province, attended the conference and presented awards to the winners. Tiejian Heavy Industry Open Rock Tunnel TBM (TBM) was successfully selected into the top ten innovative products and won the first product innovation award, becoming the only product selected for underground engineering equipment.

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.
