China Railway Construction Heavy Industry's "Long Distance Space Spiral Hard Rock Tunnel Boring Machine" Won the Gold Prize of China's Innovation "Good Design" in 2023

Recently，At the 2023 China Innovative Design Conference and Good Design Award Presentation Conference，Railway Construction Heavy Industry“Long-distance space spiral extra-hard rock tunnel Boring Machine”Won 2023“Good design”Gold Award。It is reported that，The selection was recommended by good design organizations and 15 partners in seven regions of the country.，Comments by letter、Preliminary evaluation、Final Rating Series Review，Finally, 10 gold awards were produced.、20 Silver Awards。

The world's first large-slope spiral tunnel Boring Machine independently developed by China Railway Construction Heavy Industry Co., Ltd.，The large size and high load capacity cutter and the conical cutter head with small space between cutters are designed, which are suitable for extremely hard rock formation，And that rock break capacity of the cutter head in the extremely hard rock formation is improve.，Effective rock breaking capacity exceeds 300 MPa，The monthly footage of extremely hard rock strata reaches 312 meters.；An attitude adaptive propulsion system was developed to match the shape of the continuous turning tunnel.，And that attitude control capability is improve.，TBMHorizontal turning capacity 200 m，Vertical turning capacity 380 m；A double belt storage bin is developed to adapt to the online transfer of belt conveyor.，Two belts are used to complete 7 kilometers of spiral uphill slag tapping.，Transportation volume of muck per hour≥300 tons；It solves the problem of hard rock breaking in Beishan underground laboratory in China.、It is difficult to turn continuously、Three Difficult Problems of Efficient Slag Tapping，It provides technical equipment solutions for rapid construction of engineering ramp。

The China Good Design Award is based on the Chinese Academy of Engineering.，Gathering many domestic design model products、System、Process and flow、Typical cases of business and service modes，Domestic Authoritative Design Award in the Field of Innovative Design。President of China Innovative Design Industry Alliance、Honorary President of China Mechanical Engineering Society、Academician Lu Yongxiang pointed out，The Good Design Award is an important measure to enhance China's innovative design capability.，Since its inception in 2015, it has successfully held eight sessions.，A large number of complex systems and equipment representing the high level of innovative design in China have been selected.，To further promote the strategy of innovation-driven development，Make positive contributions to building an innovative country。

Facing the new situation and new challenges，Railway Construction Heavy Industry Focuses on Differentiation、Customized high-end equipment R & D and manufacturing，Committed to solving world-class underground construction problems，Provide a total solution，Customize more heavy equipment for global customers、Provide better solutions for China、Contribute more Chinese wisdom。
