The First TBM Exported from China to Italy Successfully Completes Excavation

On February 22, 2024, as the cutting head of the CREC 699 shield machine, developed by China Railway Engineering Equipment Group Co., Ltd. under CRHIC, slowly penetrated through the wall, the excavation phase of the Italian CEPAV railway project was brought to completion, marking that the first TBM exported to Italy by China had successfully completed its excavation work.The CEPAV project, located in Northern Italy, is a high-speed railway that spans from Milan to Verona. Comprising two tunneling sections, the tunnel stretches for a total of 9.6 kilometers. CREC 699 shield machine is 155 meters long, with an excavation diameter of 10.03 meters and overall weight of 1800 tons. Throughout the excavation process, the machine has achieved a maximum excavation mileage of 38 meters per day and 704 meters per month.

Dual-line Tunneling Project Completed by the Largest Combined Rectangular PipeJacking Shield Machine

On January 19, 2024, the equipment takeover ceremony was held at the site of the Shenzhen Subway Line 12 Project (Phase II). The dual-line tunneling engineering has been completed by adopting “CREG 1179” (“Dayu · Juejin”), the super-large cross-section combined rectangular pipe-jacking shield machine jointly developed by China Railway Engineering Equipment Group Co., Ltd. (CREG) under CRHIC and other units. It is the first time in the world that super-large section machinery is used in underground excavation of metro station, which is of revolutionary significance to the construction method of urban metro stations.The platform station is 208 meters long, the single track of the jacking section which covers the left and right tracks is 70 meters, and the section of the formed station is 22.6 meters wide and 13.5 meters high. The earthing in the site is shallow, with abundant groundwater around it. And there is a newly built culvert below the site, thus facing such challenges as hig...
