It is reported that China railway construction heavy industry TBM is the only product in China's construction machinery industry to enter the Beijing exhibition hall to participate in this exhibition

it is understood that the key product of this exhibition is China's first hard rock tunneling machine (TBM) independently developed by China railway construction heavy industry relying on the national "863 Plan". It successfully runs through the first section of the "Yinsong Yinchang" diversion tunnel, the largest water diversion project in Jilin Province. The maximum monthly excavation reaches 1209.8 meters, creating the largest TBM excavation history in China

it is reported that this Hard Rock TBM, which runs through Jilin drinking water project, has a 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, mucking, ventilation, drainage and other functions, and can safely, environmentally and efficiently complete tunnel construction at one time. It has been listed in the National 863 plan and 973 Plan of the 12th Five Year Plan for research. It safely crosses the special unfavorable geological zone with changeable rock strata, and successfully tunnelled 6863 The structure of the fixture the fixture itself has no fixed structure (for example, the metal wire can be clamped by winding, or two flat plates can be clamped for 5 meters, creating a new record of domestic TBM construction with a monthly average footage of 756.3 meters, a maximum daily footage of 86.5 meters, and a continuous footage of more than 920 meters in May and June, creating the most similar tunnel construction in China. In recent years, thanks to technical support, the construction has been smooth, and the task has been completed 110 days ahead of the planned construction period
