近日,由上海城建隧道股份设计研发的超大矩形顶管掘进机在河南郑州纬四路下穿中州大道隧道接收井准确进洞,圆满完成我国自主知识产权超大顶管装备在中原大地的“处女航”。郑州纬四路下穿中州大道隧道位于郑州市郑东新区和中心城区分界线中州大道下方,采用矩形顶管机施工,施工过程中存在着大断面、长距离顶管顶进等技术难题,并且在顶进过程中还将穿越各类复杂的地下管线,工程难度较大、风险较高。值得一提的是,此次担任隧道掘进任务的矩形顶管掘进机“中州一号”尺寸为世界之最,已申请多项国家专利、发 Recently, the super-large rectangular pipe jacking machine designed and developed by Shanghai Urban Construction Tunnel Co., Ltd. passed through the receiving well of Zhongzhou Avenue under Weibei Road, Zhengzhou, Henan Province, and successfully completed the tunneling of the ultra-large pipe jacking equipment with independent intellectual property rights in the Central Plains. “. Zhongwei Avenue under Weibei Road in Zhengzhou is located at the bottom of Zhongzhou Avenue, between Zhengdong New District and downtown area of ​​Zhengzhou City. Rectangular pipe jacking machine is used for construction. During construction, there are technical problems such as large cross section and jacking of long distance jacking pipe, etc. In the process of jacking will also cross all kinds of complex underground pipeline, the project more difficult and higher risk. It is worth mentioning that this time as a tunnel boring task of rectangular pipe jacking machine ”Zhongzhou One " size for the world, has applied for a number of national patents, made
