Preventing concrete leakage in tunnel lining formwork is crucial for the structural integrity, durability, and aesthetics of the tunnel. Leakage can lead to honeycombing, voids, exposed rebar, and ultimately compromise the lining’s performance. How to prevent concrete leakage in tunnel lining formwork I. Formwork Design and Fabrication: Tight Joints: This is paramount. Formwork panels must be precisely […]

In modern tunnel construction, the tunnel lining trolley—also known as a formwork trolley or lining formwork system—is a crucial piece of equipment used to support and shape the inner concrete lining of tunnels. As tunnels are built in various geological conditions and for different purposes (such as transportation, mining, or water conveyance), the choice of lining […]

Double-row slewing bearings are critical components in heavy machinery, designed to handle significant axial, radial, and moment loads while enabling rotational movement. Due to the demanding environments they operate in, they are susceptible to various faults. Understanding these common issues and their solutions is crucial for maintaining equipment performance and longevity. Common Faults of Double-Row Slewing […]

Double-row slewing bearings are crucial components in many heavy-duty machines, and noise can be a significant indicator of an underlying problem. Troubleshooting the noise involves a systematic approach to identify the cause and implement the correct solution. Double row slewing bearing noise troubleshooting 1. Identify the Type of Noise and When it Occurs: Normal Sounds: A […]

Prefabricated steel structures have become a popular choice in modern construction due to their strength, durability, and cost-effectiveness. One of the most common questions buyers and contractors have is about the price per ton of prefabricated steel. The price per ton of prefabricated steel structure can vary significantly due to several factors, including the type of steel, […]
