Urban Tunneling Challenges

Surface Disruption and Safety Risks
Urban infrastructure projects are tough. City streets are hard to access. Heavy traffic makes moving things difficult. Underground utilities make things complicated. You must think about how the public is affected. There are risks like ground sinking or holes forming. Stopping traffic is not easy. It costs money and can upset people.
Tunneling accidents can happen. Water and mud rushing in cause almost half of accidents. Collapses and big changes in shape cause over a third of incidents. Some tunnels, like Dayaoshan Tunnel, had big accidents from mud and landslides. The old Tanna Tunnel had a huge rush of mud each day during building. Soft rock can change shape by more than 20 centimeters. This happens when there is a lot of stress.
Crew Exposure in Confined Spaces
You need to keep crew exposure low in tight spaces. This keeps your team safe and your project running well. Confined spaces have dangers that can hurt workers. The table below shows some risks you should know:
|
Hazard Type |
Description |
|---|---|
|
Atmospheric Risks |
Not enough oxygen, poisonous gases like hydrogen sulfide, and air that can catch fire. |
|
Physical Hazards |
Getting trapped in loose stuff, stuck, and not much room to move in emergencies. |
|
Rescue Complications |
Bad air and physical dangers make rescue hard. |
Working near highways and railways is risky for the public. You must protect other people and their property. Crew exposure goes up when workers are close to fast traffic.
CEGC helps you deal with these problems. Projects like the Yangtze River to Huaihe River Water Diversion and Foshan Xuda Power Tunnel show how CEGC’s trenchless solutions help city contractors. You can trust CEGC for tunnel machines and Microtunnelling Machines that lower exposure and make things safer.

|
Rotation Speed |
Tracks how fast the tunneling head spins. |
|
Face Pressure |
Measures pressure at the tunnel face. |
|
Inclination |
Watches the angle of the machine. |
|
Grouting Pressure |
