According to reports, this shield machine has a total length of 60 meters, a total weight of more than 1600 tons, and a total power of 11,870 kilowatts, which is the highest in China.
Involved in the field of tunnel boring machine manufacturing, this is a major measure for the North Heavy Industry Group to adapt to the development of “major equipment, high-end complete setsâ€. Through the introduction of digestion, absorption and innovation, we have mastered the entire series including the earth pressure balance shield. Manufacturing technology for machine, mud-water balance shield machine and hard rock roadheader. Among the many bidding projects in China, Beifang Heavy Industry Group, as the only bidding entity in China, has repeatedly defeated foreign competitors and won the bid for 24 large tunnel boring machine manufacturing contracts.
The Beijing Railway Underground Diameter Line Project won by the North Heavy Industry Group is the largest diameter double-track electrified railway tunnel project in the city. It starts from Beijing Railway Station in the east, west to Beijing West Railway Station, and is adjacent to Mingcheng Wall and Zhengyangmen. Therefore, it was listed by the Beijing Municipal Government as “the most difficult and risky underground project under constructionâ€. On November 5th, this shield machine passed the acceptance of experts, and all the indicators met the factory requirements.
Heavy creation of China's largest diameter shield machine
The Heavy Industries Group of the North Heavy Industry Group lasted 10 months to manufacture China's largest mud-water balance shield machine with a diameter of 11.97 meters. On December 7, this "big Mac" split for the Beijing Railway underground diameter line project was developed. Dismantled and shipped to the capital. This is the eighth unit manufactured by the Heavy Group and the fourth shield machine manufactured this year. Building the world's largest shield machine manufacturing base, the North Heavy Industry Group has taken another solid step.
