Shotcrete of Shennong Tunnel in Taijiao Railway contracted by China Railway Tunnel Group

In the north of China, these areas along the border of Shanxi and Henan provinces are surrounded by many mountains, but the transportation is difficult. Taijiao railway which was built over 40 years ago is unable to meet the requirement of modern society, so new Taijiao railway is newly built.

Taijiao high-speed railway was built on 16th June. Shennong tunnel with length of 11.54km was the most difficult to construct. Many difficulty such as insufficient strength of tunnel lining concrete, cavity, leakage had been solved by successfully CRTG.

Over 3,000 meters of concrete lining of Shennong Tunnel has passed non-destructive testing by several testing departments. Wet shotcrete machine HBT-12D manufactured by our company has played an important role in concrete shotcreting. Both shotcrete effect and efficiency won the praise of our customer.
