Reinforced Soil Wall is a composite material formed by fascia, frictional Soil, and the Reinforcement (Steel/Polymer). The Reinforcement layers are mechanically connected to a range of facings, such as RCC Panel, Concrete Block, Gabion, Geobags etc. as per the aesthetic, suitability and other technical requirements of the Project. Reinforced Soil Wall are strong, durable and versatile. RS Wall can be designed to accommodate ground movements during construction, and some years thereafter. Reinforced Soil Wall can be constructed for more than 20m or so following the codal provision. The Reinforced Soil Wall can be used for the landscaping work also.
We are in the construction of the following types of Walls for the last several years and the structures constructed by us are performing satisfactorily.
- Reinforced Soil Wall with Block Fascia Unit
Reinforced soil wall is a composite system consisting of concrete block units in combination with a mass of soil which is reinforced and stabilised by geogrid. This type of wall units is self-aligning. They are cast with an inter-locking system in the form of an anchor shear key built into each unit which enables the alignment of blocks between two rows and connection to geogrid. The shear key also ensures consistent batter. Another key feature offered by these units is the staggered hollows formed by the alignment of blocks, when filled with gravel behave as vertical stone columns (via aggregates) which adds additional stability to the wall. Reinforced soil walls with block fascia and geogrid reinforcement are relatively flexible structures. Concrete blocks are dry-cast and because of its size and modularity, it provides a flexible fascia to the reinforced soil wall structure.
- Reinforced Soil Wall with Precast Fascia Unit
A Mechanically Stabilized Earth (MSE) retaining wall is a composite structure consisting of alternating layers of compacted backfill and soil reinforcement elements, fixed to a wall facing.
The wall facing is relatively thin, with the primary function of preventing erosion of the structural backfill. Soil retaining walls are designed to bring stability to natural slopes in construction projects. Stabilization for MSE retaining walls comes from the interaction between the backfill and soil reinforcements, involving friction and tension. The result is a coherent gravity structure that is flexible, stable and can carry a variety of heavy loads.
Reinforced soil wall comprises of thin pre-cast reinforced concrete fascia panels, polymeric strips geostrap connected to the pre-cast units by passing around cavity shaped Connectors and passing around anchor bars at the rear, the earth fill and accessories, The connectors are cast into the panels. Geostrap is generally laid in zigzag pattern passing around the rear anchor bars. Rear anchor bar is used just to keep the geostrap in position during the filling and compaction operation and has no design the filling and compaction operation and has no design significance. The polymeric strips are typically spaced at 1.0m c/c in horizontal plane and 0.8m c/c in vertical plane. Geo-stap is provided in varied strengths between 30kN to 100kN.
- Reinforced Soil Wall with Gabion Fascia Unit
The Reinforced Soil Wall with Gabion Fascia is a worldwide used systems designed for use in a wide range of applications in road, mining and rail infrastructure works. This System is a modular system to form a gabion fascia MSE wall with integrated tail-mesh to provide additional reinforcement for soil reinforcement. The system consists of gabion baskets for the main fascia unit, thus creating the rectangular shaped cells used for stone confinements. The gabion baskets are made of elements built using hexagonal mesh made of galvanized plastic wire 2.70 mm in diameter. Thus, this is executed by combining the embankment behind the front side of the retaining structure with tensile elements such as geogrid, hexagonal mesh, etc. This type of structure is stable by combination with tensile elements and the surrounding backfilled soil. The front side of the structure serves an aesthetic purpose and prevents local erosion, and tensile elements used as a reinforcement to hold the fascia combinedly served as a soil retention system. The system makes the construction of a retaining structure with a very steep frontal inclination as per the design requirement.
