INSIDE tỷ lệ kèo cá cược bóng đá TBM TUNNELING ROBOT’S DEEP DIVE AT HANOI METRO LINE 3

As of August 25, tỷ lệ kèo cá cược bóng đá entire TBM, including tỷ lệ kèo cá cược bóng đá cutterhead and auxiliary equipment, is now fully underground. tỷ lệ kèo cá cược bóng đá machine has excavated approximately 100 meters, installed 7 temporary tunnel segments, and assembled 58 permanent tunnel segments.

After nearly a month of TBM operation, tỷ lệ kèo cá cược bóng đá tunneling process encountered challenges due to tỷ lệ kèo cá cược bóng đá machine drilling through stiff clay formations, requiring a reduction in speed. However, after adjusting tỷ lệ kèo cá cược bóng đá soil conditioning agent ratio—a substance sprayed in front of tỷ lệ kèo cá cược bóng đá TBM cutter head to soften tỷ lệ kèo cá cược bóng đá geological layer and facilitate excavation—tỷ lệ kèo cá cược bóng đá 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, tỷ lệ kèo cá cược bóng đá 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.
