The Tuen Mun – Chek Lap Kok
Link (TM-CLKL) will provide a direct route between the Northwest New
Territories and Hong Kong – Zhuhai – Macao Bridge (HZMB), the Airport and North
Lantau. The TM-CLKL Northern Connection
Sub-sea Tunnel is the first vehicular tunnel in Hong Kong to be constructed
under the sea using Tunnel Boring Machines (TBMs). When boring underneath the seabed, the
excavation chamber at the front of the TBM is under high pressure (up to a
maximum of 6 times of atmospheric pressure). Specially trained workers need to
routinely carry out maintenance works in the pressurized excavation chamber for
inspecting and replacing worn out cutter discs of the TBM cutterhead. The speakers will give an overview of the
tunnel construction and Hong Kong’s unprecedented application of hyperbaric
works in tunnelling including the relevant regulations, hyperbaric modes and
the Contractor’s proposal and implementation.
Free of Charge.
