Digestion and introduction of technology and innovation
To make the Chinese roadheader and shield machine develop its own research and development capabilities as soon as possible, Wang Jianye believes that the best technology path is the introduction, digestion, absorption, and innovation, plus integrated innovation, and cited examples from Japan and South Korea. In the advancement of science and technology, the combination of foreign technology and independent innovation is introduced. Based on the introduction and introduction of advanced technologies and equipment, efforts are made to innovate and integrate supporting technologies to form independent intellectual property rights and core competitiveness.
He said: "In fact, we have introduced many technologies such as cutter head material technology, hydraulic transmission technology, electric drive control technology, steel structure design and welding technology, and information network technology. Now we need to do digestion and absorption, And then innovate."
Like most other industries, the heavy machine industry has introduced many foreign advanced technologies and equipment, but the problem of re-introduction, light digestion, absorption, and re-innovation is very prominent. At present, the company’s production contracts are full and have long since taken into account the absorption of imported technology, and even talk about re-innovation.
Experts pointed out that the state should strengthen the macro-management of the introduction, digestion, absorption, and re-innovation of major technological equipment such as large-scale roadheaders. For example, through the investment of state funds, enterprises and the society as a whole will be encouraged to increase the amount of capital investment they have absorbed, change the situation in which the imported technology is rich and powerful, and absorb and lose money. The scientific and technological forces involved in production, research, and research are jointly digested and absorbed. Innovation. For the introduction of major equipment, user units should absorb the participation of manufacturing enterprises, jointly track the development of international advanced technologies, and carry out innovative activities based on digestion and absorption and localization to form independent intellectual property rights.
Wang Mengshu said that neither the tunneling machine nor the shield machine is a general-purpose device, and different machines must be designed according to the different geological conditions of the underground. In the design, it is necessary to combine civil engineering and machinery, and it is mainly civil engineering. In other words, the development of the equipment must be based on the project, with the construction unit as the main body, and the construction unit should provide the design parameters, and carry out debugging and acceptance of the equipment. In the past, when Chinese companies were developing equipment, manufacturing companies were often disconnected from construction units. Equipment produced was often not suitable for engineering needs.
F policy recommendations
Opportunities for companies to innovate independently
In order to improve the independent R&D level of large-scale construction machines such as China's large-section roadheaders as soon as possible, Wang Jianye proposed four policy suggestions: First, manage the market well. The so-called good management of the market is to manage import well and give domestic companies an opportunity for independent innovation. For the import of major technical equipment, a high tariff policy should be implemented. Second, reform the standard management system. The new product standard should be proposed by the company and it is best to publish it through an intermediary agency such as an industry association. Third, the first set of major equipment must be purchased domestically, and orders must be made in advance. Equipment that was needed in 2010 cannot be ordered until 2009. Fourth, the scientific and technological development of products should be managed centrally and the recommendations should be concentrated in the National Development and Reform Commission.
Wang Mengshu also believes that the issue of localization of roadheaders should be led by the National Development and Reform Commission, with decision-making under it, and the role of the society and association should be fully utilized.
Wang Mengshu also reminded the importance of the development and manufacture of small shields and small boring machines, because of its large usage, accounting for more than 80% of all usage. In order to fundamentally change the situation in which pipelines are buried and dug, the small shields and small roadheaders in the construction of underground underground trenches and sewers in the city should have many Applications.
Experts pointed out that after more than 40 years of hard work, China has initially formed a team of scientific research, design, manufacture and construction of boring machines. This is the basis for the establishment of a roadheader industry in China. In the long run, we cannot always rely on foreign equipment and talents to develop underground space. We must establish our own industrial system for roadheaders. This will not only meet the urgent needs of the project, but also save a lot of foreign exchange and drive the development of other industries. .
G advantage enterprise
Heavy machinery companies have obvious advantages
With regard to the problem of “maintaining†the manufacturing of tunnelling machines and shield machines, there has been a dispute between the construction machinery industry and the heavy mining machinery industry. Afterwards, we finally reached a consensus that who can do it. Now it seems that the final production, or several heavy machinery companies.
At present, in addition to the Shanghai Tunnel Company, there are companies such as the Second Heavy Machinery Group, Shanghai Heavy Machinery Factory, Dalian Heavy Machinery Group, Shenyang Heavy Machinery Group, and Shougang Heavy Machinery Company in the production of roadheaders or shield tunnels.
Shanghai Tunnel Stock Co., Ltd. has now formed the advantages of shield machine R&D and mastered the core technology of tailor-made shield machine for different regions and geological conditions. The second heavy machinery group is a large-scale Chinese machinery manufacturing enterprise integrating development, design, and manufacturing.
Dalian Heavy Industries Crane Group is a large-scale state-owned enterprise established by the reorganization of Dalian Heavy Industry Group and Dalian Daqi Group, two leading enterprises in China's heavy machinery industry. In the past two years, the Group has cooperated with Germany's Herrenknecht Company and American Robbins Company to produce tunnel boring machines.
At the beginning of last year, Shenyang Heavy Machinery Group Co., Ltd., a joint venture with Germany-based WIRTH drilling equipment manufacturing company and French NFM Technology Co., Ltd., jointly created a new company, Shenyang Wilt Heavy Tunnel Engineering Machinery Complete Equipment Co., Ltd. The newly-built enterprises will mainly rely on projects such as the Cross-river Tunnel in the south of China and the urban subway in the north to produce roadheaders.
Wang Mengshu believes that Luoyang can also become a roadheader research and development base. He pointed out that Luoyang has a bearing factory and a mining machinery factory, and the Ministry of Railway Tunnel Engineering Bureau is also in Luoyang. During the development process, the tunnel bureau can carry out structural design according to different geological conditions. The mine machinery factory conducts process design and is responsible for processing. Finally, the two companies jointly perform assembly and commissioning.
As for so many enterprises in the production or preparation for the production of roadheaders and shield machines, will not form a decentralized problem, Wang Jianye gave a negative answer. He said that each type of equipment must have a business group in order to create complementary advantages.
H typical business
Shanghai Tunnel Company
Shanghai Tunnel Engineering Co., Ltd. is a listed company. In the early 1990s, it developed China's first earth pressure balance boring machine. In 2005, Shanghai Tunnel Joint Stock Company took the lead in developing China's first "anterior number" of metro shield machines with independent intellectual property rights, and its market price was only two-thirds of that of imported shields. In the course of construction progress, the “anterior number†continuously updated the shield machine to advance the record, and the fastest advancement was 38.4 meters.
Relevant person in charge of Shanghai Tunnel Stock Co., Ltd. had publicly stated that the company has now formed the advantages of shield machine R&D and mastered the core technology of tailor-made shield machines for different regions and geological conditions. At the same time, the company has a number of shield machine design and manufacturing talents. It has built China's first experimental platform with independent intellectual property rights and the world's largest multi-shield machine, providing intellectual support and hardware for the industrialization of shield machines. Protection.
Shanghai Tunnel Company revealed that the company will continue to study the key manufacturing technologies for the domestic industrialization of the metro shield machine, and seize the opportunity from the localization, serialization, and intelligent development of the shield machine, thereby expanding into the entire construction field and making it bigger. Strong China shield industry.
Second Heavy Machinery Group
The Second Heavy Machinery Group is a large-scale Chinese machinery manufacturing enterprise integrated with development, design, and manufacture. It has more than 600 designers and technicians, including 55 experts enjoying special government allowances, and has experience in organizing the development of large-scale complete sets of equipment technologies. And talent. In the late 1980s, Erzhong Group began to enter the roadheader industry. At the beginning of 1991, the company selected technical personnel to go to Germany's famous underground construction company Hochtief to carry out tunneling machine construction and equipment training. It is reported that the Group has signed an agreement with Australian Terratec Corporation to establish a roadheader design company. The purpose is to support Terratec's technology and rely on the design company's technical operations to give full play to the advantages of the manufacturing capabilities of the company. The company has built its own proprietary intellectual property technology to fill gaps in domestic boring machine technology and in China. Even in the international market, there is a large market advantage for the roadheader manufacturing base.
Wang Jianye stated that the Group is located in the western part of China, the west route of the South-to-North Water Diversion Project, as well as the construction of many railways, highways, large and medium-sized hydropower stations and other projects. For the roadheaders needed for these projects, the second-tier has obvious geographical advantages. While shortening the transportation distance in large numbers, it will also reduce the cost of installation, commissioning and service.
