TerraLink® Shored MSE walls
RECo engineers have pioneered this innovative solution to link a new structure to an existing structure with TerraLink® anchored earth retaining wall technology. These MSE structures are utilized for widenings or adding new structures by linking the new wall by way of anchors or nailing to an existing concrete retaining wall, or a natural feature such as sloped terrain where only a narrow space is available for the necessary soil reinforcements and backfill.
The Reinforced Earth® and TerraLink® technologies can be combined to ensure a continuous facing and sound structural behavior.
Mainly used in;
> Road and railway widenings
The continuous increase in road and railway traffic in urban areas makes the existing infrastructure under-dimensioned. Infrastructure widening with structure additions using our TerraLink® MSE solution is a quick and efficient fix to loosen traffic bottlenecks and stabilize existing structures.
> Earth shoring
TerraLink® anchored retaining walls are an excellent cost-effective way for building a conventional earth-retained structures or a shoring system in close proximity to an existing slope or structure reducing high costs involved in typical design conceptions for the significant earthwork.
The TerraLink® anchored earth retaining wall solution
Components resembles our typical Reinforced Earth® MSE wall solution:
- Facing panels are made of precast concrete or welded wire mesh
- Steel or geosynthetic soil reinforcement strips are connected to the facing elements
- Select or engineered backfill
The TerraLink® connections
Our new TerraLink® anchored retaining walls are meant to be linked to an existing structure with either one, or a combination of the two different methods for linking:
> Friction link
Alternating layers of soil reinforcements, each layer connected to one or the opposing surface
- those being solely connected to the back face of the new structure
- those being solely connected to the face of the existing structure
> Direct link
All soil reinforcement connecting the two extremities are structurally linked directly to one another.
Prior to the TerraLink® anchored retaining walls configuration, our engineers will assess the conditions of the existing structure(s) as it is important to evaluate the stability of the existing structure and the environment. We consult with you on internal and external stability in support of the new, reconfigured structure, including revised load conditions and extended service life.
Advantages of TerraLink® shored MSE walls
