According to Jining Qilu Evening News 17, located in the North District Ren Xing Lu underground pipe gallery is under construction, the research and development of independent innovation of Yangzhou Xin Guang heavy equipment Co. Ltd. patent technology - 3 meters high, 2.7 meters wide (2.2 meters *2.5 meters clearance) two rectangle shield machine set in the successful use of engineering construction. Become the first application in the industry. The development of this technology makes the construction of underground comprehensive pipe gallery farewell to the "round pipe jacking" and "rectangular buried" era, avoids the road excavation, solves the problems of many joints and leaks, and improves the structural strength and beauty of the segment structure of the underground pipe gallery.
Yangzhou Xin Guang heavy equipment limited company independent innovation research and development of shield machine technology patent in November 17, 2015, is located in the North District Ren Xing Lu underground pipe gallery is under construction, is 30 meters high, 27 meters wide (22 meters clearance *2 5 meters) two rectangle shield used in the process of engineering construction, become the first successful the application of industry.
Earth pressure balance shield machine patent: 201220404036X
Underground pipe gallery constructed by two rectangular shield process
Two rectangular shield machine is in the case of no excavation of the road, the use of the upper and lower two pieces of splicing segments, and gradually laying forward in the tunnel. Compared with the whole country, the underground pipe gallery mostly uses open pit excavation, rectangular buried, multi piece splicing, round pipe jacking process, facing the road excavation, segment contact more, leakage problems.
Tube wall used in two rectangular shield tunneling process
"Two square rectangular", "shield construction" and other independent research and development of construction technology to build a "Jining characteristics" underground integrated gallery. At present, Jining has built more than 30 kilometers of underground integrated pipe gallery, in the province's 17 cities in the forefront. Yangzhou Guang Xin heavy equipment company through independent innovation of R & D patents, in the R & D equipment completely owned independent intellectual property rights, in the country and even the world have successfully set up construction examples, overcome all the world problems.
