Reducing noise from tunnel lining equipment is crucial for worker health and safety, environmental compliance, and maintaining good relations with nearby communities. Noise in tunnels is often amplified due to the confined space and hard, reflective surfaces. Here’s a breakdown of strategies, following the hierarchy of controls (elimination/substitution, engineering controls, administrative controls, СИЗ). How to Reduce Tunnel […]
Customizing a tunnel lining trolley (also known as a formwork traveller or gantry) is a complex engineering process, essential for ensuring the trolley perfectly matches the specific requirements of a particular tunneling project. Standard, off-the-shelf trolleys rarely fit unique tunnel geometries, geological conditions, or construction methodologies. Customized Tunnel Lining Trolley 1. Understanding the Need for […]
Туннельные тележки подкладка, also known as tunnel formwork systems or tunnel shuttering machines, are essential equipment used for in-situ concrete lining in tunnel construction. Depending on tunnel structure, размер, and construction methods, tunnel lining trolleys can be classified into several types. These are large, mobile structures used inside tunnels to support the formwork for cast-in-place concrete […]

To prevent corrosion in steel structures, a multi-faceted approach is essential, addressing design, material selection, surface preparation, and protective coatings. How to Prevent Corrosion in Steel Strcture Design Considerations Minimize Moisture Traps: Design details should prevent water accumulation and allow for drainage. Inclined surfaces, drainage holes, and avoiding sharp edges can help. Ensure Adequate Ventilation: Promote […]

Repairing weld cracks in steel structures is a critical task that requires careful planning, execution, and inspection to ensure the structural integrity is restored and the crack doesn’t return. This is a job for critical structures and should ALWAYS be performed by qualified welders following approved procedures under the supervision of experienced engineers or inspectors. Repairing Cracks […]
