tunneling machinery is an important product of construction machinery, which is mainly used in the mechanized construction of tunnels, roadways and pipe holes in the horizontal direction. It mainly includes full face tunnel boring machine (shield machine, hard rock tunneling machine, pipe jacking machine, etc.), horizontal directional drill, cantilever tunnel boring machine and other products. Its leading product is full face tunnel boring machine, and "shield machine" is a popular name for such products in China. At present, the industrial scale of China's tunneling machinery industry is about 14billion yuan. It is estimated that after several years of development, it is expected to reach a scale of 20billion yuan, which can basically meet the needs of domestic construction, and has begun to occupy a certain position in the international market

the market scale of leading products ranks first in the world.

the full face tunnel boring machine is the most advanced tunnel construction machine in the world at present. After years of technological development, after the 1950s, it has reached maturity and large-scale use. At present, according to incomplete statistics, Tian Hongfu said that the total production of full face TBMs in the world has reached more than 7000, with a retention of about 4000

the full face tunnel boring machine is a complex integrated system integrating machinery, electronics, hydraulics, control and information technology. The working environment is special, and it has high requirements for the stability, reliability and adaptability of products. Therefore, the R & D, manufacturing and use of the full face tunnel boring machine has been the weakness of China's manufacturing and construction enterprises for a long time. In fact, before the beginning of this century, China's full face TBM market and technology were basically monopolized by professional companies in the United States, Japan, Europe and other developed countries, mainly including heirik, wilt, Robbins, Mitsubishi Heavy Industries, Hitachi shipbuilding, Komatsu, Kawasaki heavy industries, Ishikawa, etc

after 2005, with the continuous development of large-scale infrastructure construction in China, especially the launching of urban subway, water diversion project, river crossing tunnel and other projects, the demand for full face tunnel boring machine in the domestic market has expanded sharply. On the one hand, the market demand has stimulated a number of domestic enterprises to fully enter the full face tunnel boring 287 automatic fire alarm system industry through technology introduction and joint venture cooperation; On the other hand, the competent government departments recognized the importance and development potential of the full face TBM industry and gave sufficient attention and support. For example, the research and development of large slurry balanced shield machine was included in the 863 project plan of the Ministry of science and technology to promote its design, test and scientific research

after just a few years of development, in the fierce market competition, a number of domestic enterprises have stood out, and a large number of engineering and technical personnel have grown up in a large number of design, manufacturing and construction practices. Chinese enterprises can be said to have basically mastered the design, manufacturing and construction technology of conventional full face tunnel boring machines. By the end of 2012, the market share of domestic enterprises has accounted for more than 70% of the total market. The production conditions and manufacturing capacity of several top enterprises have exceeded that of most internationally renowned enterprises, and they basically have independent research and development capabilities and independent intellectual property rights, and their products have begun to enter the international market. It should be said that the industrial scale and market scale of China's full face tunnel boring machine have ranked first in the world

usher in a critical period of growth

China's tunneling machinery industry, with full face tunnel boring machines as its leading products, has ushered in a critical stage of further growth after a process of start-up, exploration and high-speed development. Of course, just like the problems encountered in the development of other manufacturing industries in China, there are still many deficiencies in the development of China's tunneling machinery industry, such as scattered industrial structure, lack of core component technology, lack of standards, weak industry management, irregular market competition and other problems, which need to be solved in the future to make the industry develop healthily and continuously

in the environment of huge market demand and market potential in China, facing increasingly fierce market competition at home and abroad, how to maintain the healthy, sustainable and stable development of the industry, I think we should form a consensus in the industry in the following aspects and work together

first, actively adjust the industrial structure, improve industrial concentration, strengthen industrial management and enterprise self-discipline, correct excessive industrial protection and local protection, oppose unfair price competition, improve the market competition environment, further strive for policy support from the competent government departments, support enterprises with independent intellectual property rights and R & D capabilities to become bigger and stronger, and improve the competitiveness of industries and enterprises

second, continue to strive to improve product R & D capabilities and technical levels. For mature products, strengthen testing and testing, stabilize product quality, and further improve product reliability; Around the National 863 plan, accelerate the research and development of key technologies of TBM and large-diameter full face tunnel boring machine

third, for some major accessories that basically need to be imported at present, such as main bearings, main drives, some hydraulic parts, control systems, etc., support powerful supporting enterprises to tackle key research and development, and strive to break the situation of completely relying on imports as soon as possible

fourth, strengthen the development of the international market. Enterprises with export conditions must focus on both domestic and foreign markets. This is an effective way to alleviate the problem of overcapacity. To explore and stabilize the international market, first, publicity to improve the popularity of our products, second, product quality should be stable and meet the construction requirements, and third, service should be in place. In addition, we must not develop domestic price competition abroad, which is detrimental to others and ourselves. There are many negative examples in other industries in this regard, so we should not repeat the mistakes
