China Ship Heavy Industry (Qingdao) rail transportation equipment Co., Ltd. was established in February 2011. It is jointly funded by Qingdao Beihai shipyard Co., 704 Research Institute and 713 Research Institute under the banner of Chinese ship heavy industry. The registered capital is 70 million yuan. It is the only tunnel boring machine production enterprise in the group. The company is located in the Qingdao high and new technology industry development zone spring Yang Road, the construction covers an area of 150 mu, with annual production of 30-40 various specifications of the tunnel boring machine and rubber machinery production capacity. The company has gathered professional scientific research and manufacturing power such as machine, electricity and liquid, and established the first batch of experts' workstations in Qingdao's high-end equipment manufacturing enterprises. Since its creation, the company has passed the ISO9001 quality management system certification, CE certification, the national high and new technology enterprises, 4 invention patents and 12 utility model patents. The product has won the Qingdao Municipal Industrial Design mayor award and the Qingdao high tech Zone Innovation Achievement Award. It is now a member of the China Construction Machinery Association. . The main products of the company are DSUC dual shield hard rock boring machine (TBM) and composite soil pressure balance shield (EPB), which are integrated with machine, electricity, liquid, light, gas and information technology, and are highly intelligent, new and advanced tunnel construction technology. At present, 4 TBM and 1 sets of EPB have been built for the safety, quality and high efficiency of Qingdao Metro Line 2, which has completed a 13 kilometre mechanical driving task, and obtained the general praise of the subway companies and the construction units. In 2017, 8 TBM and 12 EPB were provided for Qingdao Metro Line 1; the TBM for the Philippines Angat diversion project was tailored to the international market; the equipment for line 4 and No. 8 of Qingdao Metro was in the process of preparation and assembly. In addition, the company has strong technical strength and extensive market base in the design, manufacture and installation of rubber conveyor belt products and large steel structure products. The company will fully rely on the strong technical and financial strength of China ship heavy industry group. Under the guidance of "the integration of the military and the people, the deep development", the company will actively introduce and absorb advanced foreign technology and further develop its own intellectual property. With the dual shield hard rock boring machine as the main product, according to the market demand, continuous research and development and improvement of the shield machine product variety series, at the same time taking into account the various underground engineering construction characteristics, R & D production pipe jacking equipment and other supporting equipment. We should strive to form diversified product structures in urban rail transit, urban integrated corridor construction, mining and diversion projects. The value-added service is taken as the new direction of product development, and the product space is expanded in the aspects of technical consultation, engineering management, maintenance, troubleshooting, operation and construction training as well as the supporting construction around the construction. We should actively develop shield machine remanufacturing technology, make full use of idle shield machine resources in the market, and upgrade it to suit different construction projects. According to the market target of "basing ourselves on Shandong, looking at the whole country and paying attention to overseas". With strength and performance, we will tap a broader market.
