Applications of Omega Seals
Omega seals are widely used in several critical applications, particularly in the construction of immersed tunnels and aqueducts. Their unique design allows them to handle significant movements and water pressures, making them essential for infrastructure projects.
Immersed Tunnels
In immersed tunnels, Omega seals serve as secondary seals, working in conjunction with Gina gaskets. They prevent water ingress and accommodate the movements caused by environmental factors such as soil settlement and temperature changes. Trelleborg’s expertise in this area has led to successful projects, including the Dalian Bay immersed tunnel in China.
Aqueducts and Canals
Omega seals are also utilized in aqueducts and canals, where they provide watertight solutions for joints subjected to considerable axial movements. The seals are designed to handle the stresses associated with temperature variations and structural shifts, ensuring long-term reliability.
Bored Tunnels
In bored tunnels, Omega seals facilitate joint movement while maintaining water pressure integrity. They are often supplied as closed rings, allowing for effective sealing between tunnel elements and structures like rail stations.
Conclusion
Omega seals are a vital component in modern infrastructure projects, particularly in demanding environments like tunnels and aqueducts. Trelleborg’s commitment to quality and innovation ensures that these seals meet the highest standards of performance and durability. With a lifespan of over 100 years and the ability to withstand extreme conditions, Omega seals are an investment in the future of infrastructure.
