China’s Cross Passage TBM Ready for Operation in Melbourne, Australia

中国专利金奖盾构进军海外

 

News from China Railway Engineering Equipment Group Co., Ltd (CREG) on October 31 -- Zhengzhou-based CREG’s “Cross Passage TBM (Tunnel Boring Machine)”, gold medal winner of China Patent Award, won the bid for cross passage construction of Western Distributor in Melbourne, Australia. So far, the installation and debugging of the Cross Passage TBM has been finished at the construction site to embrace its first performance overseas.

10月31日,记者从中铁工程装备集团有限公司了解到,该公司荣获“中国专利金奖”的“隧道联络通道用盾构机”,不久前成功中标澳大利亚墨尔本西部干道联络通道项目后,现已抵达施工现场并安装调试完毕,即将迎来该型号产品在海外工地的首次始发。

 

“Excavation usually takes 3 months with traditional freezing or grouting method, while it only takes 15 days by using Cross Passage TBMs.” According to Jia Lianhui, chief engineer of CREG, based on the Cross Passage TBM and its construction method, CREG staff has designed a complete set of equipment for horizontal tunneling, with different modules adopted according to cross passage’s length and alignment. The equipment is characterized by its high mobility, a pioneer in this field across China. Besides, CREG staff has creatively developed a balanced and uniformly-loaded support technology and formed a security system for horizontal tunneling to effectively guarantee the safety of employees during the construction.

“在开挖效率方面,传统的冷冻法、注浆加固法需要3个月时间的工程,采用联络通道盾构法施工仅需15天左右。”中铁装备总工程师贾连辉告诉记者,通过“隧道联络通道用盾构机及其联络通道掘进方法”项目,中铁装备研发人员设计出一种集成模块化横向掘进的联络通道成套设备,具有实现设备高效移动装配等先进特点,属于行业首创。同时创新性提出了主隧道平衡均载支护技术,并构建了横向掘进安全体系,可有力保障施工安全。

 

In recent years, the TBMs developed by CREG have not only been used in Dubai, Italy and Denmark, but also exported to Paris of France, the birthplace of TBM.

近年来,中铁装备研发出的一系列盾构机不仅应用到了迪拜、意大利、丹麦,还出口到了盾构机的发源地法国巴黎。(中文来源/河南日报 翻译/赵汉青 任晶晶 审校/张玉红)
