TerraLink® shored MSE structures
Shored Reinforced Earth (TerraLink) structures are widely used by engineers who have to expand or rehabilitate existing infrastructure.This innovative solution is the most effective solution in cases where there is not enough space for expansion and it is necessary to build new fill retaining structures in front of existing structures or slopes.
Road and railway widenings
The constant increase in road and railay traffic in urban areas makes the existing infrastructure inadequate. Using our TerraLink® solution, it is possible to expand infrastructure with building additions, relieve traffic bottlenecks and stabilize existing structures.
TerraLink® is a cost-effective way to construct a conventional fill retaining structure or shoring system in restrictive proximity to an existing slope or structure. Typical design concepts include significant earthworks and renovations through excavation and overfill. TerraLink offers an excellent alternative by reducing these high costs.
The TerraLink® solution
The components are similar to our typical Reinforced Earth® wall solution:
•Surface panels made of precast concrete
•Steel or geosynthetic soil reinforcements connected to the panels
• Connections with soil nails
The TerraLink™ connections
Our solution is intended to link an existing structure with the new TerraLink® structure. These structures are designed with either one, or a combination of two different methods for linking:
> Friction link
Successive reinforcement layers,
- are attached to the back face of the new structure or
- are attached to the front face of the existing structure.
> Direct link
The reinforcements at both structure boundaries are directly connected to each other.
In TerraLink® design, the characteristics of the existing structure or the condition of the existing slope (slope angle, bedrock type, etc.), the stability of the nailed structure within itself, and the analysis of the final structure to be formed play a key role.
