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

As of August 25, tỷ lệ cá cược bóng đá châu âu entire TBM, including tỷ lệ cá cược bóng đá châu âu cutterhead and auxiliary equipment, is now fully underground. tỷ lệ cá cược bóng đá châu âu 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 cá cược bóng đá châu âu tunneling process encountered challenges due to tỷ lệ cá cược bóng đá châu âu machine drilling through stiff clay formations, requiring a reduction in speed. However, after adjusting tỷ lệ cá cược bóng đá châu âu soil conditioning agent ratio—a substance sprayed in front of tỷ lệ cá cược bóng đá châu âu TBM cutter head to soften tỷ lệ cá cược bóng đá châu âu geological layer and facilitate excavation—tỷ lệ cá cược bóng đá châu âu 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 cá cược bóng đá châu âu 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.
