The world of super large section rectangular pipe jacking machine "open up" Dalian line

By December 25th, Chinese China Railway Engineering Equipment Group Limited company independent research and development of the world super large section rectangular pipe jacking machine manufacturing, assembly line in Dalian dry million manufacturing base.

      “ &rdquo development; rectangular pipe jacking machine excavation section of 10.42 meters wide, 7.55 meters high, is currently the highest in the world, breaking the 2014 in Zhengzhou Zhongzhou Street tunnel record of the world's largest rectangular shield section records.

      the rectangular pipe jacking machine is made by tunnel equipment China China Railway Engineering Group under the company on the basis of previous construction experience, through innovation, using two layer six cutter layout design, cutting area adjacent cutter mutual cross section excavation coverage will reach 95%, due to the small range of multicutter tunneling, less disturbance to the ground, the surface subsidence will be greatly reduced. The equipment line marks reached world leading level on China of pipe jacking machine product design and development in the round, rectangular series.

      “ next, open ” rectangular pipe jacking machine will be shipped to Tianjin, used in Tianjin Metro Line 11 Neijiang Road Station black cattle city entrance crossing construction.

      with the development of society, the city to speed up the process, more and more buildings, the construction of many city facilities are in contention, the ground space shortage of contradictions become more prominent, the way is to solve the contradiction of &ldquo & rdquo; development of underground space;. The development and utilization of underground space, can make the part function of the city from the ground underground, from &ldquo to “ ” 2D; 3D ” transformation, can greatly improve the space utilization of city land, alleviate the contradiction between city development and land resource.

      shield type pipe jacking machine with its excavation and construction process is simple, fast, high quality, safety, cave features such as environmental protection, has gradually become the city underground space development equipment “ ”, ditch, common pipe in the underground city of city tunnel, subway station entrance, crossing the underground parking lot, underground mall and civil air defense projects, gas storage caverns and other aspects, has a wide range of applications and market prospects.

      integrated service providers, China Railway Engineering Equipment Group China tunnel equipment manufacturing Co. Ltd. as a professional engaged in tunnel equipment research and development manufacturing and technical services, adhering to the &ldquo professional manufacturer of professional services; ” in recent years, is committed to the development of city space and tunnel construction to provide more safe and efficient, complete sets of mechanical construction the product cost is lower, and gradually formed a research and development of earth pressure balance pipe jacking machine, hard rock slurry pipe jacking machine series pipe jacking machine equipment manufacturing capacity, but also developed a drilling rig, wet machine and other mechanical products complete construction of tunnel waterproof board laying machine, spray, can provide complete solutions for customers, has provided fully mechanized excavation equipment and high intelligence for dozens of signs a number of railway, subway, urban construction and electric power field of Tunnel Engineering Close service. January 2015, China railway equipment successfully developed the largest diameter of the rock boring machine, effectively enhance the efficiency and safety of the tunnel construction, the successful occupation of the world's high ground. In April 2015, the company developed the first domestic hard rock slurry pipe jacking machine, fill the technology gaps in municipal tunnel mechanized tunneling in domestic city, small diameter under complicated geological conditions, and successfully applied to the Guangxi Nanning municipal sewage treatment works.

      at present, our products are not only used in domestic subway construction projects, and exported to Malaysia, Singapore, India, Lebanon, Israel and other countries, the &ldquo Chinese shield ” “ ” China manufacturing; new meaning, high-end smart.
