MSE retaining walls for railway structures
The inherent strength and flexibility of a Reinforced Earth® wall solution give powerful solutions for rail and transit stakeholders, their engineers, and constructors to meet strict structural, geotechnical and economical challenges of all types in terms of sizes and complexities. Reinforced Earth® and TerraTrel® mechanically stabilized earth (MSE) technologies serve as the ideal retaining wall solutions for concrete or wire mesh panel infill walls on Class I Railroads.
Under some restrictive circumstances, the most effective alternative to MSE walls will be T-Wall™. It is a precast modular retaining wall system and it offers an optimal solution when designers are challenged with constraints related to highly restrictive rights-of-way, narrow in-fill clearances, obstructions behind the wall facing, etc. Our precast modular retaining wall system, T-WALL™, has been used successfully in the railway industry for decades now.
During railway widenings and twinnings when designers encounter existing structures in close proximity to new structures, then the shored retaining wall TerraLink® solution is to be considered the best option. TerraLink® can be constructed in front of an existing structure or natural soil or rock where there is only a narrow space between the two.
Cut and cover railway tunnels
TechSpan® precast concrete arches are frequently used for the construction of railway tunnels in earth embankments or in cut-and-cover conditions. The TechSpan® solution involves a strong soil-structure interaction, associating three-hinge prefabricated concrete arches to a structural backfill. The main advantages of TechSpan® are the structural quality, rapidness of installation and adaptability to the specific clear opening size requirements of each project. Reinforced Earth® is a perfect complementary technique for the construction of head walls and wing walls when combined with TechSpan® precast concrete arches.
Noise protection for MSE walls for railway structures
The construction of railways close to residential areas can be a source of noise disturbance for the people living nearby and RECo’s sound absorbing panels have proven to be an effective solution to mitigate noise.
