Currently, CRCHI is striving toward its annual targets with full commitment and practical efforts, achieving remarkable progress in several overseas engineering projects.

"CRCHI No.1324" Slurry Balance TBM Successfully Launched

Recently, the "CRCHI No.1324" slurry balance tunnel boring machine, developed by CRCHI, was successfully launched in Singapore. It will be used for the construction of Contract CR117 of the Cross Island Line Phase 1. The machine has an excavation diameter of 7.22 meters and a total length of approximately 100 meters, with a tunneling distance of about 1,000 meters and a minimum turning radius of 300 meters. It will pass through strata mainly consisting of the Kallang Formation, with some sections crossing fault zones.

China's Largest TBM Exported to Italy Successfully Launched

Recently, the "CRCHI No.1418" earth pressure balance TBM, developed by CRCHI, was successfully launched for the Lot 1A section of the Sarno railway project in Italy. This machine is currently the largest diameter earth pressure balance TBM exported from China to Italy, marking the official start of the tunneling phase for the railway project.

"CRCHI No.1238" Double Shield TBM Successfully Launched

The innovative double shield TBM "CRCHI No.1238," developed by CRCHI, was recently launched in Singapore to support the construction of the Cross Island Line Phase 1. The machine has an excavation diameter of 7.72 meters and features a dual shield structure, allowing for turnaround launching and disassembly within the tunnel.

"CRCHI No.1265" and "CRCHI No.1264" Successfully Met Underground

The Bucheon Cable Tunnel Project in South Korea has reached a critical milestone. The "CRCHI No.1265" slurry balance TBM completed a 1,315-meter drive and successfully arrived at the designated position, where it met the "CRCHI No.1264" earth pressure balance TBM coming from the opposite direction. The two machines achieved a successful underground rendezvous and will now undergo disassembly and recovery within the tunnel.
