China's domestically developed, world's largest-diameter vertical shaft boring machine 'Qiming' was officially put into operation in Taicang City of east China's Jiangsu Province on Tuesday, for the Chongming-Taicang Yangtze River Tunnel project. #Trending #ChinaInnovates | CCTV

An Earth Pressure Balance (EPB) Tunnel Boring Machine (TBM) works by maintaining soil pressure at the tunnel face to prevent collapse and manage ground stability. It uses a rotating cutterhead to excavate soil, which is then mixed with conditioning agents to create a soil paste that balances pressure while being conveyed through screw conveyors. As the TBM advances, it simultaneously installs precast concrete segments to form the tunnel lining, ensuring structural stability. Tunnelling is vital

The Earth Pressure Balance (EPB) TBM "CREC No.1093", developed and manufactured by #CREC, successfully traversed the first section of the Wakrah and Wukair Drainage Tunnel Project in Doha, Qatar recently. This breakthrough has laid a solid foundation for the on-time completion of the project, as well as the relief of local sewage pressure. Thanks to the safe and reliable EPB TBMs "CREC No.1092" & "CREC No.1093" and the efficient quality services of CREC, EPB TBMs have been performing well on the

An Earth Pressure Balance Tunnel Boring Machine (EPB TBM) is a type of mechanised tunnelling machine designed for soft ground conditions. It operates by using a rotating cutting wheel at the front to excavate soil, which is then mixed with a controlled amount of additives to create a paste-like material. This material helps maintain pressure at the tunnel face, balancing the external earth pressure and preventing collapse. The excavated material is transported through the machine using a screw c
