Engineering Cases

At the end of 2007, by adopting cutters designed and transformed by Techgong, the engineering from Honghuayan to Renmin North Road of Chengdu Subway Line One boosts four times of mileage longer than that by adoption of the former cutters.

At the beginning of 2008, the adoption of transformation proposal of the design of Techgong strengthened lead cutters facilitates smooth achievement of the engineering from Yunfeng North Street to Beisi Road in Tiexi District in Shenyang Subway Line One and eventually the shield machines completed the whole process of construction in safety.

In Aug. 2008, Nanjing Yangtze River across-river tunnel engineering smoothly processed from the center of Yangtze River to the south of Yangtze River by adopting cutters improved and produced by Techgong after proceeding to the bottom of the river. Chairman of the board Liu Yuhai and other leaders were invited to participate in the Get-Through Celebration.

In the first half year of 2009, by adopting cutters produced by Techgong according to a new design concept, Beijing Rail Transit Line Engineering from Beijing Station to Beijing West Station normally advanced for hundreds of meters after over 67 meters by the former cutters.
