Rectangular shield machine
| ◆ Main characteristics of rectangular shield with half pipe section: |
| ● 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. |
| ● The half pipe rectangular shield machine is used in the tunnel without digging the road, using 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. |
| ● "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 GuangXin Heavy industry Co.,Ltd.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 the first construction example, overcome all the world problems. |
| ◆ JD2840*3140 Patent number of EPB shield machine：201220404306x |
