Recently，China Railway Construction Heavy Industry Co., Ltd. and Shanghai Tunnel（Singapore）Jointly built“Channel Express”The cutter head of the slurry balance shield machine breaks out of the rock，It marks the successful completion of the nine-month cross-sea water tunnel.，Help Singapore add another important water transmission trunk line。

The cross-sea tunnel connects the Tuas Water Reclamation Plant in Singapore with Jurong Island, the core industrial area.，It is one of the key infrastructure projects of Singapore's water system.。The tunnel runs under the seabed for a long distance.，High construction water pressure，And traverse mudstone for long distances.、Siltstone and sandstone，High compressive strength of rock，There is fracture zone stratum in the tunnel section.，The construction is difficult.。

According to project characteristics and construction requirements，The R & D team of Railway Construction Heavy Industry has carried out targeted design of shield machine.，It is also equipped with multiple intelligent management and monitoring systems.，For tunnel safety、Reliable、Efficient construction provides a guarantee.。

China Railway Construction Heavy Industry Integrates Value Creation into R & D Service Management，To provide customers with full escort services from equipment installation and commissioning to run-through.。“Channel Express”The maximum daily footage during shield tunneling is 17.6 meters，Maximum monthly footage of rock formation 289.6 meters，The excellent reliability of the equipment has been highly recognized by customers and owners.。
