INSIDE kết quả xổ số miền nam hôm nay TBM TUNNELING ROBOT’S DEEP DIVE AT HANOI METRO LINE 3

As of August 25, kết quả xổ số miền nam hôm nay entire TBM, including kết quả xổ số miền nam hôm nay cutterhead and auxiliary equipment, is now fully underground. kết quả xổ số miền nam hôm nay machine has excavated approximately 100 meters, installed 7 temporary tunnel segments, and assembled 58 permanent tunnel segments.

After nearly a month of TBM operation, kết quả xổ số miền nam hôm nay tunneling process encountered challenges due to kết quả xổ số miền nam hôm nay machine drilling through stiff clay formations, requiring a reduction in speed. However, after adjusting kết quả xổ số miền nam hôm nay soil conditioning agent ratio—a substance sprayed in front of kết quả xổ số miền nam hôm nay TBM cutter head to soften kết quả xổ số miền nam hôm nay geological layer and facilitate excavation—kết quả xổ số miền nam hôm nay TBM’s tunneling speed has returned to normal at approximately 35-40 mm per minute.

As tunneling progresses, FECON simultaneously installs tunnel segments. With its advanced robotic arm, kết quả xổ số miền nam hôm nay segment installation process takes around 30 to 35 minutes for each tunnel ring, which consists of six segments. Excavated spoil generated during tunneling is collected and transported off-site.
