The first shield tunneling machine in xinguang section of no. 5 subway line 6 started smoothly

Recently, the shield tunneling between the rookie park station and guangxi university station of the first phase of nanning rail transit line 5 project started smoothly, and the shield tunneling construction began.

The left line is 1458 meters long, and the right line is 1323 meters long. There are two contact channels in the section, which are all constructed by freezing method. In this section, there are many undercutting structures, complicated geological conditions and difficult construction. After long distance tunneling, the shield tunneling undercuts guangxi university station and its affiliated structure of line 1, and finally connects to guangxi university station of line 5.

This time, the first shield tunneling starts from the right line. Before the shield tunneling starts, orbital corporation has organized the compilation and review of all kinds of safety construction plans, and formulated feasible emergency plans, so as to provide reliable technical support and support for the smooth starting tunneling of the shield tunneling machine.
